Answer:

D. 12²•π

Step-by-step explanation:

Area of a circle = πr²

Radius (r) = ½ of diameter = ½*24 = 12 inches

Plug in the value into the area

Area = π * (12)²

Area = π * 12²

Area = 12²•π

Please help - ACT math practice test

bezimeni [28]

Answer:

Step-by-step explanation:

Let's look at the equation.

$h=-at^{2}+bt+c$

This is a standard negative polynomial equation.

So changing the c value will basically move the graph up/down.

$I$ is true because if it moved up or down, the h-intercept would change.

$II$ is true because if it moved up or down, the maximum would change.

$III$ is true because if it moved up or down, the t-intercept would be moved left or right.

Amber can peel 10 1/2 potatoes in 1/3 of an hour. What is her unite rate

Alexxx [7]

Given that:

- Amber can peel this amount of potatoes:

$10\frac{1}{2}\text{ }potatoes$

- And she can peel them in this time:

$\frac{1}{3}\text{ }hour$

You can determine that the Unit Rate is the number of potatoes she can peel per hour.

Since the number of potatoes is given as a Mixed Number, you can convert it to an Improper Fraction as follows:

1. Multiply the Whole Number part by the denominator.

2. Add the Product to the numerator.

3. The denominator does not change.

Then:

$10\frac{1}{2}=\frac{(10\cdot2)+1}{2}=\frac{20+1}{2}=\frac{21}{2}$

Now you can set up that:

$Unit\text{ }Rate=\frac{\frac{21}{2}\text{ }potatoes}{\frac{1}{3}\text{ }hour}$

Solving the Division, you get:

$\begin{gathered} Unit\text{ }Rate=\frac{21\cdot3}{2\cdot1}\frac{potatoes}{hour} \\ \\ Unit\text{ }Rate=\frac{63}{2}\frac{potatoes}{hour} \end{gathered}$

Hence, the answer is:

$Unit\text{ }Rate=\frac{63}{2}\frac{potatoes}{hour}$
