Answer:
[tex]Speed = \frac{3}{2}[/tex]mph
Step-by-step explanation:
Given
Distance = [tex]\frac{1}{2}[/tex] mile
Time = [tex]\frac{1}{3}[/tex] hour
Required
Determine the speed
To do this, we simply divide distance by time
[tex]Speed= \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{1}{2} / \frac{1}{3}[/tex]
[tex]Speed = \frac{1}{2} * \frac{3}{1}[/tex]
[tex]Speed = \frac{3}{2}[/tex]
Hence, the speed is [tex]\frac{3}{2}[/tex] mile per hour
Tyler's speed is 1.5 miles per hour.
The formula for speed is:
= Distance / Time
Distance = 1/2 miles
Time = 1/3 hours
Tyler's speed is therefore:
= 1/2 ÷ 1/3
= 1 / 2 x 3/1
= 3/2 miles per hour or.
= 1.5 miles per hour
Tyler's speed is therefore 1.5 miles per hour.

the Lincoln Memorial. She uses a scale of 15 ft
in the monument to 1 in. in the drawing. The
front of the monument is about 80 ft high and
200 ft long. Will Adoncia's drawing fit on an
sin.-by-11 in. sheet of paper? Explain.
8
Answer:
Since the length of the drawing is 200 ft. and equivalent to 13.33 in. with a scale of 15 ft to 1 in. and the length of the paper is 11 in., Adoncia's drawing will not fit on the sheet of paper
Step-by-step explanation:
The given parameters are;
The scale of the drawing is 15 ft = 1 in.
The actual dimensions of the monument;
Height = 80 ft.
Length = 200 ft.
Therefore, we have;
The required dimension of the paper height = 80/15 = 16/3 = 5.33 in.
The required dimension of the paper length = 200/15 = 40/3 = 13.33 in.
The given paper dimension by 11 in. which is of a dimension of that of a standard letter paper size of 8.5 in. by 11 in.
Drawing length, 13.33 in. > Paper length > 11 in.
Adoncia's drawing will not fit on the sheet of paper.

Consider the equation 3p – 7 + p = 13. What is the resulting equation after the first step in the solution?
p – 7 = 13 – 3p
2p – 7 = 13
3p – 7 = 13 – p
4p – 7 = 13
Answer:
4p - 7 = 13
Step-by-step explanation:
The first step of the solution should be to simplify the left side by combining like terms. In this case, 3p and p are the like terms and 3p + p = 4p so the answer is 4p - 7 = 13.
Answer:
4p - 7 = 13

Answer: $90,000 at 12%
and $80,000 at 9%
Step-by-step explanation:
given data:
cost of property = $170,000.
short term = 12%.
long term = 9%.
total interest paid = $18,000.
Step 1
= 0.12x + 0.09 (170,000-x) = 18,000
collect like terms
= 0.12x + 15300 – 0.09x = 18,000
divide both Sides by 0.03
0.03x = 2700
x = $90,000 at 12%

What is the difference between two measurements of
the same object with values of 3.4 and 3.42?
Answer:
The percentage difference between 3.4 and 3.42 is 0.58651% or 0.02.
Step-by-step explanation:
Find the absolute difference between two numbers: |20 - 30| = |-10| = 10
Find the average of those two numbers: (20 + 30) / 2 = 50 / 2 = 25
Divide the difference by the average: 10 / 25 = 0.4
Express it as percentages: 0.4 * 100 = 40%
in this case, it would be 3.4 and 3.42
Answer: 0.02
Step-by-step explanation: 3.42 is bigger than 3.4 and they are asking for the difference between the two measurements. So, you subtract the 3.4 from the 3.42

of the television?
18-A $450
18-B $360
18-C $320
18-D
$280
Answer:
B
Step-by-step explanation:
The total cost of the television is $360 if a woman bought a new color television with a $40 down payment and 16 monthly payments of $20 each.
It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.
We know the formula for the monthly payment:
[tex]\rm Monthly \ Payment \:=\:\dfrac{\left A\left(i\right)\left(1+i\right)^{n}\right}{\left(1+i\right)^{n}-1}[/tex]
It is given that:
A woman bought a new color television with a $40 down payment and 16 monthly payments of $20 each.
Down payment = $40
Number of months = 16
Per month payment = $20
The total cost of the television = 40 + 16(20)
The total cost of the television = 40 + 320
The total cost of the television = $360
Thus, the total cost of the television is $360 if a woman bought a new color television with a $40 down payment and 16 monthly payments of $20 each.

Answer:
[tex]\frac{s}{2t}[/tex]
Step-by-step explanation:
When you have exponents above a like term and they are being multiplied together, you add them.
For example:
[tex]a^{x} *a^{y} = a^{x + y}[/tex]
So let's group like terms in the numerator:
[tex]4r^{3} r^{-5} s^{-2} s^{-1}t[/tex] We can add terms like in the example.
[tex]4 r^{-2} s^{-3} t[/tex]
Let's rearrange the denominator.
[tex]8r^{-2} s^{-4} t^{2}[/tex]
Now we have:
[tex]\frac{4r^{-2} s^{-3}t}{8 r^{-2} s^{-4} t^{2} }[/tex] Cancel like terms
4/8 = 1/2
[tex]r^{-2} /r^{-2}[/tex] = 1 So it cancels
[tex]s^{-3} / s^{-4} = s^{-1}[/tex] = s Since s is raised to the -1 it goes on top and becomes s.
[tex]t / t^{2} = 1/t[/tex]
Now we combine everything back together:
[tex]\frac{s}{2t}[/tex]

For a parade, attendance was rounded as 10,000 to the nearest hundred. What was the
greatest and least number of people that could have attended the parade? Explain your
answer.
Answer: (9,950 to 10,049)
Step-by-step explanation:
The nearest hundred is the third digit (counting from the right).
When we round up/down, we must look at the previous digit (the second in this case).
If the digit is larger than 5, we round up
if the digit is 5 or less, we round down.
Then if the rounded number is 10,000.
The rounded down version will be:
10,049
(49 < 50, then we should round down to 10,000)
The rounded up version will be:
9,950.
this number would be the smallest number that can be rounded up to 10,000.
Then the possible range is:
(9,950 to 10,049)

Please help.
Answer:
The radius of each rug on the order is 6 ft
Step-by-step explanation:
The graph shows the relationship between the price of a rug and the radius of the rug
The number of rugs ordered by the customer = 3 rugs
The total cost of the rugs ordered by the customer = $1,350
Therefore, the cost of each rug = $1,350/3 = $450
The radius of the rugs as determined from the chart
At $450, the radius of the rug = 6 ft
Therefore;
Given that all the rugs are identical, the radius of each rug on the order = 6 ft.

a solid pyramid with a square base with side 12 cm and height 25 cm is made of metal. The metal is melted to form spherical ball bearings of radius 7 mm. How many pyramids are needed to form 2490 ball bearings?
Answer:
3 pyramids.
Step-by-step explanation:
The volume of one pyramid is 1/3 * b^2 * h
= 1/3 * 12^2 * 25
= 1200 cm^3.
The volume of one ball bearing = 4/3 * π * 0.7^3
= 1.43676 cm^3.
Therefore the volume of 2490 ball bearings = 2490 * 1 .43676
= 3577.53 cm^3.
So we need 3577.53 / 1200 = 2.98 = 3 pyramids.

- 1. 9(4 - 2x) – 3 = 4 - 6(3x – 5)
Answer:
No real solution
Step-by-step explanation:
First off I'm assuming that the 1 or -1 at the begging is just the problem number:
First you distribute on both sides
36 - 18x - 3 = 4 - 18x + 30
Then combine like terms
33 - 18x = 34 - 18x
Then rearrange the terms by adding 18x to both sides and subtracting both sides by 33. You should get:
0 = 1
When you add positive 18x it cancels the -18x out. And 34 - 33 is 1. Obviously, zero cannot equal 1 so there is no real solution
What is the range of h?
Peter invests $1000 at 4% compounded annually for 10 years and Jose invests $900 compounded annually at 5% for 11 years. Who ends up with more money? And how much more money?
Answer:
Jose ends up with more money with $59 more than Peter.
Step-by-step explanation:
To determine the amount they will have, you have to use the formula to calculate the future value:
FV=PV(1+r)^n
FV= future value
PV= present value
r= rate of interest
n= number of periods of time
-Peter:
FV=1,000*(1+0.04)^10
FV=1,000*1.48
FV=1,480
-Jose:
FV=900*(1+0.05)^11
FV=900*1.71
FV=1,539
Difference: $1,539-$1,480=$59
According to this, the answer is that Jose ends up with more money with $59 more than Peter.

Ariana borrowed some money from her friend in order to help buy a new video game
system. Ariana originally borrowed $150 and agreed to pay back her friend $15 per
week. Write an equation for L, in terms of t, representing the amount Ariana owes
her friend after t weeks.
Answer:
L = 150 - 15t
Step-by-step explanation:
Money borrowed by Ariana = $150
Money she returns each week = $15
Amount of borrowed money will decrease by $15 each week.
In 1 week she will return $15
in 2 week she will return $15*2 = $30
in 3 week she will return $15*3 = $45
...........................
similarly after t week
money she will return = Money she returns in 1 week* no of weeks
money she will return in t weeks = 15*t = 15t
where 15t unit is dollar
So, Amount of borrowed money will decrease by $15t in t week.
Amount of money she woes after t week = Money borrowed by Ariana - money returned in t weeks
Amount of money she woes after t week = 150 - 15t
Since L represents the amount Ariana owes ,her friend after t weeks
L = 150 - 15t is the correct answer
Quadrilateral WXYZ is a rhombus. What is the measure of < XWZ?
A) 64
B) 26
C) 52
D) 32
Answer:
C. 52°Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached below.
Since all the sides and angles of a rhombus are the same, hence, all the right angled triangle in each quadrant are also the same.
From the diagram, < XWZ = < XWV + < VWZ and < XWV = < VWZ
Therefore < XWZ = < VWZ + < VWZ
< XWZ = 2<VWZ
let us calculate the angle <VWZ first.
From ΔVWZ, <WVZ +<WZV + <VWZ = 180°... 1
From the diagram <WVZ = 90°, <WZV = <VZY = 64°
On substituting into 1
90°+64°+ <VWZ = 180°
154°+ <VWZ = 180°
<VWZ = 180°-154°
<VWZ = 26°
Since < XWZ = 2<VWZ
< XWZ = 2(26°)
< XWZ = 52°
Hence the measure of < XWZ is 52°
