Answer:
-3
Step-by-step explanation:
9×(12+(-5)÷(-8-13)
9×7÷(-8-13)
63÷-21
=-3
For this, it's like finding a partial volume. Altogether, there will be 10 inches of sand, because 4+6 is 10. Because it is in inches, we have to convert it to feet. 10 inches in feet is 10/12 feet, or about .833. This is then used for the volume formula instead of the 1 foot height. So, the equation is 6 times 4 times 10/12. This comes out to be 20.

You have not provided the choices, therefore, I cannot provide you with a specific solution. However, I will explain this problem for you to understand an apply on the choices you have.
Now, the perimeter of the rectangle is the summation of lengths of its four sides.
We have:
length = 12 ft
width = 9 ft
Therefore:
perimeter = 12 + 9 + 12 + 9 = 42 ft
Or: perimeter = 2(12+9) = 2*21 = 42 ft
Or: perimeter = 2*12 + 2*9 = 24 + 18 = 42 ft
Any expression that does not lead to the above result would be wrong
Hope this helps :)
Step-by-step explanation:
Value 1:
r = 5ft, h = 10ft. Substitute:
Value 2:
r = 2in, h = 4in. Substitute:
Value 3:
r = 6m. Substitute:
