Answer:

B

Step-by-step explanation:

Given

- 2.5(4x - 8) + 1.2(5x - 1)

Answer:

-10x+20+6x-1.2

Step-by-step explanation:

The given expression is

-2.5(4x-8)+1.2(5x-1)

The missing step in the given problem is when we need to apply Distributive Property

-2.5(4x-8)+1.2(5x-1)=-10x+20+6x-1.2

Therefore, the right choice is B.

Remember that Distributive property is about "distributing" the outside element with each term inside the parenthesis.

Star Wars land encompasses an area of 14.0 acres. [1.00 acre = 4046.86m2]. If Star Wars land were made into a circle, what would
Free_Kalibri [48]

Answer:

<h3>The answer is 134.29 m</h3>

Step-by-step explanation:

First of all we need to convert 14.0 acres to m²

1.00 acre = 4046.86 m²

14.0 acres = 14 × 4046.86 = 56656.04 m²

Area of a circle = πr²

where

r is the radius

To find the radius substitute the value for the area into the above formula and solve for the radius

That's

56656.04 = \pi {r}^{2}

Divide both sides by π

We have

{r}^{2}  =  \frac{56656.04}{\pi}

Find the square root of both sides

r =  \sqrt{ \frac{56656.04}{\pi} }

r = 134.29139

r = 134.29 m to 2 decimal places

Hope this helps you
