Answer:
8
Step-by-step explanation:
It depends what mathematics you know
Perhaps the most basic way would be by approximation. You could start with, say, 5. 5*5*5= 125. Then 5 is to small to be the cube root of 512.
Try 10: 10*10*10=1000: Too bi. But now we know that the number we want is between 5 and 10.
Try 8: 8*8*8=512.
There are 274.32 cm in 9 feet.
Hope this helps :)
Answer:
The answer is 75 inches.
Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.
Answer:
To convert fraction to decimal, divide 3/10, which would give you . 3 which is already a decimal. To convert decimal to percent, multiply by 100 which would give you 30, hence 30%
