Answer:
3
Step-by-step explanation:
3^10= 3^7(x^3)
59049= 2187(x^3)
59049/2187= x^3
27=x^3
Do the square root of 3 to both sides and you end up with x=3.
Hope this helped :)

Answer:
(D) 30pi inches
Step-by-step explanation:
First, we use the given volume, the given height, and the formula of the volume of a cylinder to find the radius of the base. Then we use the radius of the base to find the circumference of the base.


We set the formula equal to the volume and replace h with 30 in.


Divide both sides by 30pi in.

Take the square root of each side.


The radius of the base is 15 in.
Now we use the radius of the base and the formula of the circumference of a circle to find the answer.

Answer:
Proportion states that the two fractions or ratios are equal
As per the statement: Mrs. Hwang is taking her vehicle to the shop to have the gas tank expanded by 10 gallons. Now, it costs her $42.56 to fill the tank. Once the new tank is in, it will cost her $72.96
Let the tank size now be x
Since, the gas tank expanded by 10 gallons = x + 10
by definition of proportion ;

by cross multiply we get;

using distributive property;

Subtract 42.56x from both sides we get;

Divide both sides by 30.4 we get;
x = 14
Therefore, the tank is her now is, 14 gallons
