3 x $37.25 = $111.75
$229.25 - $111.75 = $117.50
$117.50 ÷ 5 = $23.50
So the answer is B
-1 is the answer
Have a great day
To solve this problem we are going to use the simple interest formula:

where

is the sum of the <span>interest and the principal
</span>

is the principal

is the interest rate in decimal form

is the time in years
<span>
We know for our problem that </span>

,

, and

. Now, let

represents our interest rate. To express the interest rate in decimal form, we are going to divide the rate by 100%:


.
Now that we have all the values we need, lets replace them in our simple interest formula to find the interest rate:

![21000=15000[1+(0.01x)(5)]](https://tex.z-dn.net/?f=21000%3D15000%5B1%2B%280.01x%29%285%29%5D)




We can conclude that the interest rate of your cousin's loan was 8%.
Answer:
The gradient of the line segment between the two points is -1
Step-by-step explanation:
The gradient of the line segment between two points is also known as the slope,
We can find this by using the formula; y₂ - y₁ / x₂ - x₁
The points given to us are;(-1,2) and (-2,3).
This implies x₁ = -1 , y₁=2 x₂ = -2 y₂= 3
We can now proceed to insert our values into the formula;
Gradient = y₂ - y₁ / x₂ - x₁
= 3 - 2 / -2-(-1)
= 1 / -2 + 1
=1/-1
Gradient = -1
Therefore the gradient of the line segment between the two points is -1
Answer:
A. 62.8 in.
Step-by-step explanation:
Circumference of a circle = πd
Diameter (d) = 20 in.
Substitute
Circumference = π × 20
Circumference = 62.8318531
Circumference = 62.8 in. (Approximated to nearest tenth)
