Answer:
To do this you want to divide 7560 by 4. This leaves you with 1845. Therefore, you need 1845 4-inch stacks to build that high. You are not done though. You need to multiply 1845 by 58. This gives you 107,010. It would take 107,010 quarters to get to the top.
Step-by-step explanation:
Answer:
117
Step-by-step explanation:
-3 + m /9 = 10
-3 + m/9 = 10
m/9 = 10 + 3
m/9 = 13
m/9×9 = 13 × 9
m = 117
A quarter Multiplied by a number plus five is equivalent to a number Minus seven
The height of the tank must be at least 1 foot, or 12 inches. We know the floor area (which is length x width) must be at least 400 inches. Therefore these minimum dimensions already tell us that the minimum volume is 400 x 12 = 4800 cubic inches. Since we have a maximum of 5000 cubic inches, the volume must be within the range of 4800 - 5000 cubic inches.
We can set the height at exactly 1 ft (or 12 inches). Then we can select length and width that multiply to 400 square inches, for example, L = 40 inches and W = 10 in. This gives us a tank of dimensions 40 x 10 x 12 = 4800 cubic inches, which fits all the criteria.
