Each basketball comes in a cubic box with side lengths of 1 foot. The locker is 3 feet long, 2 feet wide, and 5 feet high. How m

ser-zykov [4K]

Answer:

30 basketballs

Step-by-step explanation:

one layer would be 3 x 2 = 6

to find how much you would need to cover the bottom of the locker, you would use the numbers 3 and 2, then multiply them and you get 6. You would need 6 basketballs to cover the bottom of the locker. That would be your first layer

5 layers would be 6 x 5 = 30

So the bottom would be filled with 6 basketballs. Now since the locker is 5 feet high multiply 6 x 5 and that would get you your total of basketballs

What is the solution to StartFraction h over negative 24 EndFraction less-than-or-equal-to 18?

attashe74 [19]

Answer:

h greater-than-or-equal-to negative 432

Step-by-step explanation:

$\frac{h}{-24} \leq 18$

* multiply each side by -24 *

$\frac{h}{-24} *-24=h\\-24*18=-432$

IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )

Thus,

h ≥-432

Which can also be expressed as h is greater than or equal to negative 432

Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.
