Answer:
x = 12
Step-by-step explanation:
Given x varies as the cube root of y then the equation relating them is
x = k
← k is the constant of variation
To find k use the condition x = 6 when y = 8, thus
k =
=
=
= 3
x = 3
← equation of variation
When y = 64, then
x = 3 ×
= 3 × 4 = 12
Answer:
6.5%
Step-by-step explanation:
You can find the tax rate by finding the percentage that the initial price increased by.
First, subtract the initial price from the price after taxes.
509.07 - 478 = 31.07
Knowing this we can find the tax rate using an equation like this.

Now we substitute in our values.

With X being the tax rate, we cross multiply both fractions.
3107 = 478x
From here, we solve for x by dividing 3107 by 478.
x = 6.5
Therefore the tax rate is 6.5 percent.
(Note that when you are trying to find the tax rate that you divide by the initial price before taxes to get the correct value.)
Okay Bright, so the central angle is 36 degrees, so according to the formula you have on the top of the screen, we have to do 36/360, which is 1/10 or 0/1.
Then we multiply that by the radius squared. 12^2 = 144.
Finally, we multiply 144 by 0.1, which is 14.4. So
our answer is H. 14.4
.
Notice that we don't multiply the radius squared by

, since the answers are in terms of

.
Hope this helped!
