Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5
Answer:
62.5% or 63%
Step-by-step explanation:
He has $8. To find the percent of money that he spent on the purchase you put the amount spent over the total amount.
In this case, he spent $5. You would put that $5 over the $8, 5/8. When you divide, you get 0.625. To get a percent, you would multiply this number by 100. You end up with 62.5, or 63 if you round up.

Step-by-step explanation:
<u>Area Of Compound Regions</u>
When a surface has no regular shape, it can be usually divided into smaller regular parts and add their areas. The surface shown in the figure can be split into 3 smaller rectangles (please refer to the image below).
The area of the yellow part is
The pink region has a height h=4 yd - 3 yd = 1 yd
The area of the pink region is
The total area is
Simplifying
(x + -16) * 2 = 256
Reorder the terms:
(-16 + x) * 2 = 256
Reorder the terms for easier multiplication:
2(-16 + x) = 256
(-16 * 2 + x * 2) = 256
(-32 + 2x) = 256
Solving
-32 + 2x = 256
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '32' to each side of the equation.
-32 + 32 + 2x = 256 + 32
Combine like terms: -32 + 32 = 0
0 + 2x = 256 + 32
2x = 256 + 32
Combine like terms: 256 + 32 = 288
2x = 288
Divide each side by '2'.
x = 144
Simplifying
x = 144
