Answer: Third option.
Step-by-step explanation:
By definition, the number 64 and the number 9 are perfect squares.
A perfect square it that number obtained by squaring a whole number.
In this case, 64 is obtained by squaring the number 8 and the number 9 is obtained by the squaring the number 3. Then:
Therefore, you can rewrite the expression as following:
This matches with the third option.
Answer:
2441 and 2437
Step-by-step explanation:
The two whole numbers are
2441 and 2437
When added, gives 4878
Note that the scale factor of B to A is (4 / 8) = 1/2
So....the volume of B =
Volume of A * (scale factor)^3 =
2720 * (1/2)^3 =
2720 * 1/8 =

When x varies inversely with y then you'll have
xα1/y
x=k/y where k is the proportionality constant
when x=8. y=10. k=?
8=k/10
make k the subject of the formula
k=10×8
k=80.
When x=6. y=?.k=80
6=80/y
Make y the subject of the formula
y=80/6
y=40/3
