The cube of 20 can be written as 20^{3}. Split the 20 up into 2*10. Even though we are doing the cube of this value, first do 2*3=8 and then do 10^3=1000. Now multiply these numbers together so it is 8*1000=8000. Which is answer choice D. 8000

First, let's calculate the actual cost.
239*6=1434 is the actual cost of six nights.
The formula for percent error is |\frac{measured value-accepted value}{accepted value}|*100
The bars (|) stand for absolute value which gets rid of the negative sign if there is one.
Plug in the values: |\frac{1434-1450}{1450}|*100
<span>|\frac{-16}{1450}|*100

32.5% of what is 12.48?
Agata [3.3K]
Percent is the amount of something in a whole per amount of the whole times 100. To solve for this problem, we write an expression and assign x as the number that represents the number where 32.5% is equal to 12.48.

(32.5/100)x = 12.48
x = 38.4

A: 42.4<br> B: 80.2<br> C: 92.8<br> D: 101.6
Vlad1618 [11]

Answer:

B. 80.2 square inches

Step-by-step explanation:

This figure is a composite figure made up of two rectangles (see attachment).

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

In the top rectangle, the length is 3 and the width is 10.2, so A = 3 * 10.2 = 30.6 square inches.

The length of the bottom rectangle is 8 and the width is 6.2, so the area is A = 8 * 6.2 = 49.6 square inches.

Add these together: 30.6 + 49.6 = 80.2 square inches.
