Answer:
The principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Step-by-step explanation:
Given
Total accrued Amount A = 400.00 (Let say $)Time period t = 9 yearsInterest rate r = 8% = 0.08To determine
Principle P = ?
Using the formula
P = A / (1 + rt)
substituting A = 400.00, t = 9 and r = 0.08 in the formula
P = 400 / ( 1 + (0.08 × 9))
P = $232.56
Therefore, the principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.

Answer:
69°
Step-by-step explanation:
if CA and AT are congruentsides, this means that the angle of C and T must also be the same.
In order for a triangle to be a triangle, they must meet the angle of 180 degrees.
We know CAT is = to 42
So we subtract 42 from 180 = 138 degrees
we then divide 138 by 2 and we get 69
angles c + t are both 69 degrees
Answer:
69°
Step-by-step explanation:
The measure of angle A is given as 42 and the sum of interior angles in a triangle is equal to 180° we subtract 42 from 180 and divide the result with 2 because this is an Isosceles triangle since |AC| = |AT| m<C = m<T
(180 - 42) ÷ 2 = 69°
help, I need help really bad
Answer:
135
Step-by-step explanation:
you need to explain the actual question and not put an image without context
Answer:
angle a = 70
angle b = 45
angle c = 65
Step-by-step explanation:
Now we will try to find the measure of the unknown angle together. Starting with angle b.
Angle b and 135 make a 180 angle together therefore the following expression.
angle b + 135 = 180
b = 45
Now that we have angle be we can try to find angle a. As we know, vertical angles are always equal to one another. Angle a and 70 are vertical to each other.
a = 70
Now that we have angle a and b we can finally find c. A triangle is the a sum of 180 degrees so, a + b + c = 180
70 + 45 + c + 180
c = 65
4. Eddie drops a heavy book onto the floor. What does the energy of the book turn into when the book hits the floor?
O radiant energy
sound and heat energy
potential energy
O kinetic energy
Answer:
Heat and sound energy
Step-by-step explanation:
It starts off as potential energy, which is then converted to kinetic energy and by impact it'll develop a sound and heat energy.
Sound waves generates heat, and if some glass fell on the floor you can heat the shatter from the sound waves. The same goes for a book.
3. Jalen is a lifeguard at a public swimming pool and is planning to string
flags across both diagonals of the rectangular pool. He knows the
dimensions of the pool are 50 meters by 25 meters.
What value represents the length of flag string Jalen will need to reach
across the diagonals of the pool?
Answer:
[tex]Flag = 55.90m[/tex]
Step-by-step explanation:
Given
[tex]Length = 50m[/tex]
[tex]Width = 25m[/tex]
Required
Determine the length of the flag
Because the flag crosses through opposite diagonals of the pool. Its length is the length of the diagonal of the pool.
This is calculated using Pythagoras theorem.
[tex]Flag^2 = Length^2 + Width^2[/tex]
Substitute values for Length and Width
[tex]Flag^2 = 50^2 + 25^2[/tex]
[tex]Flag^2 = 2500 + 625[/tex]
[tex]Flag^2 = 3125[/tex]
Take positive square root of both sides
[tex]Flag = \sqrt{3125[/tex]
[tex]Flag = 55.90m[/tex]
Hence, the length of the flag is approximately 55.90m

Reflect (4,3) across the x-axis. Then reflect the result across the y-axis. What are the coordinates of the final point
Answer: (-4,-3)
Step-by-step explanation:

(-4,3)quadrant 2 wasn't used in this
(4,-3) quadrant 3
(-4,-3)Quadrant 4
just trust me and I don't know how this is
college homework lol but okay
Reflection involves mirroring a point over a line. When (4,3) is reflected across the x and y axes, the final point is (-4,-3)
Given that
[tex](x,y) = (4,3)[/tex]
The rule of reflection across the x-axis is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex](4,3) \to (4,-3)[/tex]
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex](4,-3) \to (-4,-3)[/tex]
Hence, the final point of (4,3) is (-4,-3)

Which statements describe the graph of 2 8/9 ≥ x on a number line? Select three options.
Answer:
✔️The graph contains point zero
✔️There's a closed circle on 2⁸/9
✔️The arrow points to the left
Step-by-step explanation:
The inequality, 2⁸/9 ≥ x, implies that 2⁸/9 is either equal to x or more than x. In other words, the highest value of x is 2⁸/9. Possible value of x is equal to or less than 2⁸/9.
This, on a number line, we would graph the information as follows:
✔️The graph contains point zero
Rationale: point zero is less than 2⁸/9
✔️There's a closed circle on 2⁸/9
Rationale: this indicates 2⁸/9 is included in the possible value of x
✔️The arrow points to the left
Rationale: possible value of x ranges from 2⁸/9 and below.

Exercise 2.4.2: Proving statements about rational numbers with direct proofs. About Prove each of the following statements using a direct proof. (a) The product of two rational numbers is a rational number. Solution (b) The quotient of a rational number and a non-zero rational number is a rational number. Solution (c) If x and y are rational numbers then is also a rational number.
Answer:
See Explanation
Step-by-step explanation:
(a) Proof: Product of two rational numbers
Using direct proofs.
Let the two rational numbers be A and B.
Such that:
[tex]A = \frac{1}{2}[/tex]
[tex]B = \frac{2}{3}[/tex]
The product:
[tex]A * B = \frac{1}{2} * \frac{2}{3}[/tex]
[tex]A * B = \frac{1}{1} * \frac{1}{3}[/tex]
[tex]A * B = 1 * \frac{1}{3}[/tex]
[tex]A * B = \frac{1}{3}[/tex]
Proved, because 1/3 is rational
(b) Proof: Quotient of a rational number and a non-zero rational number
Using direct proofs.
Let the two rational numbers be A and B.
Such that:
[tex]A = \frac{1}{2}[/tex]
[tex]B = \frac{2}{3}[/tex]
The quotient:
[tex]A / B = \frac{1}{2} / \frac{2}{3}[/tex]
Express as product
[tex]A / B = \frac{1}{2} / \frac{3}{2}[/tex]
[tex]A / B = \frac{1*3}{2*2}[/tex]
[tex]A / B = \frac{3}{4}[/tex]
Proved, because 3/4 is rational
(c) x + y is rational (missing from the question)
Using direct proofs.
Let x and y be
Such that:
[tex]x = \frac{1}{2}[/tex]
[tex]y = \frac{2}{3}[/tex]
The sum:
[tex]x + y = \frac{1}{2} + \frac{2}{3}[/tex]
Take LCM
[tex]x + y = \frac{3+4}{6}[/tex]
[tex]x + y = \frac{7}{6}[/tex]
Proved, because 7/6 is rational
The above proof works for all values of A, B, x and y; as long as they are rational values

Rimo spends £588 on a plane ticket and $130 on airport tax. Using £1 = $1.34, what percentage of the total cost does Rimo spend on airport tax?
Give your answer rounded to 1 dp.
PLEASE HURRY I'VE POSTED THREE TIMES THIS QUESTION BUT NO ANSWERS ONLY WATCHERS
Answer:
Percentage = 14.2%
Step-by-step explanation:
Given the following data;
Cost of plane ticket = £588
Airport tax = $130
£1 = $1.34
To find the percentage of the total cost spent on airport tax;
First of all, we would convert the ticket cost in pounds (£) to dollars ($).
Cost of plane ticket = £588 to $ = 588 * 1.34 = $787. 92
Total cost = Cost of plane ticket + Airport tax
Total cost = 787. 92 + 130
Total cost = $917.92
[tex] Percentage \; cost = \frac {130}{917.92} * 100 [/tex]
[tex] Percentage = 0.1416 * 100 [/tex]
Percentage cost = 14.16 to 1 d.p = 14.2%
Therefore, the percentage of the total cost spent on airport tax by Rimo is 14.2 percent.

a wagon is pulled at speed of 40.0 m/s by a horse exerting 1800 newton horizonal force what is the power of horse
Answer:
The power of horse is: P = 72000 W
Step-by-step explanation:
Given
F = 1800 Nv = 40.0 m/sTo determine
P = ?
Using the formula
[tex]\:\:\:P=\overrightarrow{F\cdot }\overrightarrow{v}[/tex]
The ⋅ in the formula represents a scalar product, defined by:
[tex]\overrightarrow{v\cdot }\overrightarrow{w}=|v||w|cos\:\theta[/tex]
The angle Ф is zero because F and v are are parallel.
Thus the cosine is 1.
Therefore,
P = (1800) (40.0)
P = 72000 W
Hence, the power of horse is: P = 72000 W
