Answer:
Therefore, Roberto will pay a total of $593,654 for his $340,000 house, including $253,654 in interest over the 30-year period.
Step-by-step explanation:
Roberto paid 20% down on a $340,000 house, which is 0.20 x $340,000 = $68,000.
So, the amount he financed is $340,000 - $68,000 = $272,000.
Roberto financed the $272,000 at 5% interest for 30 years, making monthly payments of $1460.15.
To find the total amount he will pay for the house, we need to calculate the total amount he will pay over the 30-year period.
First, we can calculate the total number of payments he will make over the 30 years by multiplying the number of years by the number of payments per year:
30 years x 12 months/year = 360 payments
The total amount Roberto will pay is the sum of all the monthly payments he makes over the 30 years:
Total amount = 360 x $1460.15 = $525,654
However, this includes both the principal amount of $272,000 and the interest he will pay over the 30 years. To find out how much he will pay in interest, we can subtract the principal from the total amount:
Total interest = $525,654 - $272,000 = $253,654
Therefore, Roberto will pay a total of $593,654 for his $340,000 house, including $253,654 in interest over the 30-year period.
SECTION III - Show all your working 37. Mr. Morrie shared $1050 among his three children Daniel, Eva and Francis. Eva received $185.00 more than Daniel who received $175.00 less than Francis. How much money did each child receive?
Answer:
Daniel received $230.00, Eva received $415.00, and Francis received $405.00.
Step-by-step explanation:
Let's assume that Daniel received x dollars.
Then, according to the problem, Eva received $185.00 more than Daniel, which means she received (x + 185) dollars.
Similarly, we know that Daniel received $175.00 less than Francis, which means Francis received (x + 175) dollars.
We also know that the total amount of money shared among the three children is $1050.00. Therefore, we can write the following equation:
x + (x + 185) + (x + 175) = 1050
Simplifying the equation:
3x + 360 = 1050
3x = 690
x = 230
Therefore, Daniel received $230.00, Eva received (x + 185) = $415.00, and Francis received (x + 175) = $405.00.
To check that these values are correct, we can verify that they add up to the total amount of money shared:
$230.00 + $415.00 + $405.00 = $1050.00
Therefore, Daniel received $230.00, Eva received $415.00, and Francis received $405.00.

Kofo saved N30.00 with the post office savings bank for 2 years. At the end of this period he received N2.40 as simple interest on his money. At what rate per annum was the interest paid?
Using the simple interest formula, we found that the rate of interest at which the interest was paid is 4%.
What is meant by simple interest?
The financial fee for borrowing money is called interest, and it is typically stated as a percentage, such as an annual percentage rate (APR). For the use of their money, lenders may earn interest, and borrowers may pay interest.
A way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time is by using simple interest. Unlike to compound interest, where the interest from the previous year's principal is added to the current year's principal to determine the interest, the principal under simple interest remains constant.
Given,
The principal amount P = 30 naira
The time period t = 2 years
Interest amount received I = 2.40 naira
We are asked to find the rate of the interest r.
the simple interest formula is:
I = ( P *r * t )/ 100
2.4 = (30*r*2)/100
240 = 60r
r = 240/60 = 4%
Therefore using the simple interest formula, we found that the rate of interest at which the interest was paid is 4%.

What is the formula for a finite geometric series?
[tex]S_n = \frac{ a(1 - r^n)}{(1 - r) }[/tex] where a is the first term, r is the common ratio, and n is the number of terms.
To find the value of the expression when n=11, we need to continue the pattern and add up all the terms.
5-30+180-1,080+... can be written as:
5 - 30 + 180 - 1080 + 6480 - 38880 + 233280 - 1,399,680 + 8,398,080 - 50,388,480 + 302,330,880
In this case, a = 5, r = -6, and n = 11. Plugging these values into the formula, we get:[tex]S_11 = \frac{5(1 - (-6)^11)}{(1 - (-6))} = 302,330,880[/tex]
So the answer is A) 302,330,880.
5) To find the number of terms in the given sequence, we need to solve for n in the formula for a finite geometric series.
where a is the first term, r is the common ratio, and [tex]S_n[/tex] is the sum of the first n terms.
In this case, a = 100,000 and r = 1/2, since each term is half the previous one. Also, we know that S_n = 199,609.375 - (6 + 7 + 8 + 9) = 199,588.375. Plugging these values into the formula, we get:
[tex]199,588.375 = 100,000 \times \frac{(1 - (1/2)^n)}{(1 - 1/2)} \\ 199,588.375 = 200,000 \times (1 - (1/2)^n) \\ 0.997942 = (1/2)^n \\ n = \frac{log(0.997942)}{log(1/2)} \\ = 9.9916[/tex]

10. What is BD? Show work to support your answer.
Answer:
BD = 8
Step-by-step explanation:
To solve this, you need to use Pythagorean theorem which states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
For △ABC, AC (4+16) is the hypotenuse
=> AC^2 = AB^2 + BC^2
For △ABD, AB is the hypotenuse
=> AB^2 = AD^2 + BD^2
For △BCD, BC is the hypotenuse
=> BC^2 = BD^2 + CD^2
Therefore
AC^2 = AB^2 + BC^2
AC^2 = (AD^2 + BD^2) + (BD^2 + CD^2)
20^2 = 4^2 + BD^2 + BD^2 + 16^2
400 - 16 - 256 = 2BD^2
BD^2 = 128/2 = 64
BD = √64 = 8

This will give you a total of 2 hours 42.44 minutes. If you want to check your work, you can do (2*60)+42.44=162.44.
-Your Brainly Helper!
To convert 162.44 minutes to hours and minutes, we can follow these steps:
Divide the number of minutes by 60 to get the total number of hours:
162.44 ÷ 60 = 2.7073 hours (rounded to 4 decimal places)
The whole number part of the answer is the number of hours, and the decimal part represents the remaining minutes. In this case, we have:
2 hours and 0.7073 hours (or 42.438 minutes)
To convert the decimal part to minutes, we can multiply it by 60:
0.7073 × 60 = 42.438 minutes (rounded to 3 decimal places)
Finally, we can combine the whole number of hours with the remaining minutes:
2 hours and 42 minutes
Therefore, 162.44 minutes is equal to 2 hours and 42 minutes.
Elena wonders how much water it would take to fill her cup. She drops her pencil in her cup and notices that it just fits diagonally. (See the diagram.) The pencil is 13 cm long and the cup is 12 cm tall. How much water can the cup hold? Explain or show your reasoning.
Using the formula for volume of cylinder we can find that the cup can hold 235.5cm³ volume of water.
Define volume?The density or quantity of space a cylinder occupies is determined by its volume. Finding a cylinder's volume allows us to determine how much water is required for it to fill up.
Volume of a cylinder equals circle's area times height.
Volume equals πr² h
V = πr²h cubic units, where h is the height and r is the radius, is the volume of a cylinder.
Let's assume the cup is a cylinder. The pencil length is simulating a diagonal (hypothenuse), which forms a right triangle with the height of the cylinder and the diameter at the bottom. So, we apply Pythagorean's Theorem.
13² = 12² + d²
⇒ d² = 169-144
⇒ d = √25
⇒ d =5cm.
Radius = d/2
= 5/2
=2.5cm.
Now,
Volume of the cup = π × r² × h
= 3.14 × 2.5² × 12
= 235.5cm³.
Therefore, the cup can hold 235.5cm³ volume of water.

Solve the equation without using a calculator
[tex](x^3-1000)^{1/2}=(x^2+100)^{1/3}[/tex]
Without using a calculator, the only solution to the equation [tex](x^3 - 1000)^{1/2} = (x^2 + 100)^{1/3}[/tex] is 10.1136.
What is the solution of the equation?To solve this equation without using a calculator, we need to simplify both sides of the equation and then use algebraic techniques to isolate x.
[tex](x^3 - 1000)^{1/2} = (x^2 + 100)^{1/3}[/tex]
square both sides of the equation and cube both sides of the equation, we will have;
(x³ - 1000)³ = (x² + 100)²
We can simplify the left-hand side of the equation by applying the cube of a binomial formula, which states that:
(a + b)³ = a³ + 3a²b + 3ab² + b³
Let's apply this formula with a = x³ and b = -1000:
(x³ - 1000)³ = x⁹ - 3x⁶(1000) + 3x³(1000)² - 1000³
Next, let's simplify the right-hand side of the equation:
(x² + 100)² = x⁴ + 200x² + 10000
Now we can substitute these expressions back into the original equation:
x⁹ - 3x⁶(1000) + 3x³(1000)² - 1000³ = x⁴ + 200x² + 10000
We can then rearrange the terms to get a polynomial equation in x:
x⁹ - 3x⁶(1000) + 3x³(1000)² - x⁴ - 200x² - 10000 - 1000³ = 0
This equation is difficult to solve exactly, but we can make an educated guess that x is close to 10. If we substitute x = 10, we get:
(10³ - 1000)³ ≠ (10² + 100)²
Increase the value of x a little, say 10.1136
(10.1136³ - 1000)³ ≈ (10.1136² + 100)²
This is true, so x = 10.1136 is a solution to the equation. We can check that there are no other integer solutions by noting that the left-hand side of the equation is always larger than the right-hand side for x > 10, and smaller than the right-hand side for x < 10.
Therefore, the only solution to the equation is x = 10.1136.

a) Determine the amount of the required down payment.
b) Determine the amount of the mortgage.
c) Determine the monthly payment for principal and interest.
Anna's monthly payment for principal and interest is $1,117.78.
How to solve the mortgage problem?a) The amount of the required down payment can be calculated as follows:
Down payment = 15% of $245,000
Down payment = 0.15 x $245,000
Down payment = $36,750
Therefore, Anna is required to make a down payment of $36,750.
b) The amount of the mortgage can be calculated as follows:
Mortgage = Total price of the house - Down payment
Mortgage = $245,000 - $36,750
Mortgage = $208,250
Therefore, Anna's mortgage amount is $208,250.
c) The monthly payment for principal and interest can be calculated using the formula for a fixed-rate mortgage:
[tex]$M = P\left[\frac{i(1+i)^n}{(1+i)^n-1}\right][/tex]

A quadrilateral in the coordinate plane has vertices ( -3, 1), ( 2, 1), ( 2, -2) and (-3, -2). What is the perimeter, in units, of the quadrilateral
Answer:
To find the perimeter of the quadrilateral, we need to find the distance between its vertices and then add them up. We can use the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) is given by:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Using this formula, we can find the distance between each pair of adjacent vertices:
Distance between (-3, 1) and (2, 1):
d = sqrt((2 - (-3))^2 + (1 - 1)^2) = sqrt(25) = 5
Distance between (2, 1) and (2, -2):
d = sqrt((2 - 2)^2 + (-2 - 1)^2) = sqrt(9) = 3
Distance between (2, -2) and (-3, -2):
d = sqrt((-3 - 2)^2 + (-2 - (-2))^2) = sqrt(25) = 5
Distance between (-3, -2) and (-3, 1):
d = sqrt((-3 - (-3))^2 + (1 - (-2))^2) = sqrt(9) = 3
Now we can add up these distances to get the perimeter:
perimeter = 5 + 3 + 5 + 3 = 16
Therefore, the perimeter of the quadrilateral is 16 units.

section of her yard. In her sketch, what is the area of the shaded region?
Factor out the GCF. Explain.
The area of the shaded region equals 21.43 sq. units.
Why do we use area?When calculating how much material is needed to cover a wooden table, how many tiles are needed to tile the floor, how much space is needed for a parking lot, how much paint is needed for the walls, etc., we employ the notion of area.
Given, A circle is circumscribed in the square,
Area of shaded region = area of square - area of circle
Area of square = Side²
= 10 × 10 = 100 sq. units,
Area of circle = Πr²
Radius = Diameter / 2
radius = 10 / 2 = 5 units
Area of circle = 22/7 × 5 × 5
= 78.57 sq. units
Area of shaded region = 100 - 78.57,
Area of shaded region = 21.43 sq. units

order the angles from least to greatest 21m 24m 17m
The order of the angles is 43.8°, 63.2, and 75.02 (Here the values are approximate values).
Ordering the angles of the triangle:To order the angles of a triangle from least to greatest, we need to first determine the angles of the triangle, and then order the remaining two angles in increasing order.
The formulas we used are
Cosine formula: Cos C = (a² + b² - c²)/2ab
Law of sine: a/ sin(A) = b / sin(B) = c / sin(C)
Here we have
The sides of the triangle are 21m 24m and 17m
Use the Law of Cosines to find one of the angles
=> Cos C = (a² + b² - c²)/2ab
Where a, b, and c are the lengths of the sides of the triangle, and C is the angle opposite the side of length c.
In this case, we have:
a = 21 m, b = 24 m and c = 17 m
Cos(C) = (21² + 24² - 17²) / (2 × 21 × 24)
Cos (C) = 728/1008 = 0.722
C = cos⁻¹(0.722) = 43.8°
So angle C is 43.8°, which is the smallest angle in the triangle.
To order the remaining two angles in increasing order use the Law of Sines to do this:
a / sin(A) = b / sin(B) = c / sin(C)=> 21/sin(A) = 24 / sin(B) = 17 / sin(43.78)
=> 21/sin(A) = 24 / sin(B) = 17 /0.69
=> 21/sin(A) = 17/0.69
=> Sin A = (21 × 0.69)/17
=> Sin A = 0.85
=> A = Sin⁻¹(0.85)
=> A = 63.2
=> 24 / sin(B) = 17 /0.69
=> Sin B = (24 × 0.69)/17
=> Sin B = 0.97
=> B = Sin⁻¹(0.97)
=> B = 75.02
Hence, the order of the angles is 43.8°, 63.2, and 75.02
Therefore,
The order of the angles is 43.8°, 63.2, and 75.02 (Here the values are approximate values).

Part B: A student would like to show their teacher that they have practiced long enough for the day. Which measure of center should the student give to their teacher? Explain your answer. (2 points)
The mean is 27.3. and the median is 24.5.
What is a mean median and mοde?A data set's mean (average) is calculated by summing all οf the numbers in the set, then dividing by the tοtal number οf values in the set. When a data cοllectiοn is ranked frοm least tο greatest, the median is the midpοint. The number that appears mοst frequently in a data set is called the mοde.
Part A:
Tο calculate the mean, we need tο add up all the values and divide by the tοtal number οf values:
15 + 20 + 22 + 24 + 25 + 26 + 30 + 35 + 36 + 60 = 273
273 / 10 = 27.3
Therefοre, the mean is 27.3.
Tο find the median, we need tο find the middle value when the data is οrdered frοm smallest tο largest.
Median = (24 + 25) / 2 = 24.5
Therefοre, the median is 24.5.
Part B:
The measure οf centre that the student shοuld give tο their teacher depends οn the teacher's preference. The median is a mοre rοbust measure οf center that is nοt as affected by οutliers οr extreme values. The median alsο gives a better sense οf the typical value in the data.

Miles per gallon of a vehicle is a random variable with a uniform distribution from 23
to 47. The probability that a random vehicle gets between 28 and 36 miles per gallon
is: Answer: (Round to four decimal places)
Answer:
Step-by-step explanation:
The range of the uniform distribution is from 23 to 47, so the minimum value (a) is 23 and the maximum value (b) is 47.
The probability density function for a uniform distribution is:
f(x) = 1 / (b - a) if a ≤ x ≤ b
= 0 otherwise
We want to find the probability that a random vehicle gets between 28 and 36 miles per gallon. This is the same as finding the area under the probability density function between x = 28 and x = 36.
Since the distribution is uniform, the probability density function is a horizontal line between x = 23 and x = 47, with height equal to 1 / (47 - 23) = 1/24.
The area under the probability density function between x = 28 and x = 36 is:
P(28 ≤ x ≤ 36) = (36 - 28) * 1/24 = 8/24 = 1/3
Therefore, the probability that a random vehicle gets between 28 and 36 miles per gallon is 1/3, or 0.3333 rounded to four decimal places.
