You can see from the above that only four whole numbers are there whose squares and cubes have the same number of digits
Rectangle Area = length • width
5x • (x + 2) = area
(5x^2 + 10x) is the area, with no further ways to simplify.
Answer:
the answer is 4 hours
Step-by-step explanation:
42-10=32
for the gas money
32 divided by 8 =4 hours
-- Take. -5 . -- Add 12. to it. -- To the result, add 10. --- From that result, subtract 7 . -- The current result is the value of the expression.
Answer:
The problem stats you cannot compress the balls; so you can not round up. You must round down. That means 4 x4 x4. There will be 16 balls per layer and 4 layers. So 48 balls.
The volume of the box is 12%5E3 inches.
You are told the diameter of a ball is 2.5 inches. So the radius of a ball is 1.25 inches
The volume of each ball is %284%2F3%29pi%2Ar%5E3
Subtract the volume of 16 balls from the volume of the box to get the volume of the packing bead material
To get the percentage of beads to box, divide the bead volume by the box volume and multiply by 100%
