Let x is the interest rate

$17,500 * 2 * x = <span>$2975
</span>$35,000x = $2,975
x = $2,975/$35,000
<span>x = 0.085

0.085 * 100 = 8.5%

Answer: annual interest rate was 8.5%

How do I do this problem please help the middle one

skad [1K]

The slope is 0.10

The y-intercept is 30

The slope, which is 0.10, represents how much is changed per mile driven.

The y-intercept, which is 30, represents the base price to rent the car.

c = 0.10m + 30 represents the situation.

Melissa is stacking storage cubes in a crate the bottom of the crate is 8 inches by 12 inches. The volume of the crate is 768 cu

Karo-lina-s [1.5K]

Answer:

12 cubes can fit in the create.

Step-by-step explanation:

We know that the volume of a the crate is 768 in³, and the definition of the volume is:

$V=A*h$

Where:

V is the volume
A is the area (A=8*12 in²)
h is the height

So $h=\frac{V}{A}=\frac{768}{12*8}=8 in$

Now, we know that the storage cube has a length of 4 in so we have a volume equal to 64 in³. Therefore we just need to divide 768 in³ by 64 in³ it is 12.

Finally, 12 cubes can fit in the create.

I hope it helps you!

A circle has the equation (x-2)^2 +y^2 =5. What are the coordinates of the circle's center?

Elina [12.6K]

The circle with center (h, k) and radius r has equation
.. (x -h)^2 +(y -k)^2 = r^2

You have
.. h = 2
.. k = 0
.. r = √5

The center is (h, k) = (2, 0).
