Answer:
the answer is A) h=3V/(Pi*r^2)
Step-by-step explanation:
This question is asking to solve for h, the equation is allready solved for V.
to solve for h means to get h by itself on one side of the equation.
1) V=(1/3)*pi*r^2*h. Divide 1/3*pi*r^2 to the other side of the equation
2) V/(1/3)*pi*r^2=h. 1/3 on the bottom denominator means we can multiply the reciprocal to the bottom and the top and get an equivalent answer. In short, move the 3 from the 1/3 onto the top.
3) (3*V)/(pi*r^2)=h. Simplify.
4) 3V/(Pi*r^2)=h.
If the side length of the original tile is x, then the area is length * width, or x*x which is x^2. That's the first box up there. The new length is x - 4, since the length is what he cut away from. That's the second box up there. The width is still x, so the third box is x, and the area removed is 4x, the last box. So here's your info: box 1: x^2; box 2: x - 4; box 3: x; box 4: 4x
Answer:
Step-by-step explanation:
Number of bags = Total money spent / Cost of each bag
x = number of bags of chips
Simply divide 17.50 by 1.25 to work out how many bags of chips he can purchase.
Number of bags = Total money spent / Cost of each bag
= ?
to be honest I agree that would be 6s
