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.
They will use 300 pickles on 100 hamburgers.
Step-by-step explanation:
Given,
Ratio of hamburgers to pickles = 3:9
Ratio in simplest form = 1:3
It means one hamburger uses 3 pickles.
No. of burgers = 100
Quantity of pickles = No. of burgers * Pickles per burger
They will use 300 pickles on 100 hamburgers.

Setting d = 0 gives the points where she is at the surface.
therefore 0= 0.1t^2 - 3.5t + 6
apply the quadratic formula to get t = (3.5+- √12.25-4*0.1*6)/0.2
t = (3.5 <span>3.1384709653)/0.2
t= </span>1.80764517352 and <span>33.1923548265

That's as long as I haven't made a mistake :D
Answer:
x=7
Step-by-step explanation:
4(2x-3) = 6x+2
8x-12 = 6x+2
2x = 14
x=7
