I need some help, see the picture for the question. Solve for V
Andrei [34K]

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.

andreev551 [17]

Answer:

7

Step-by-step explanation:

Since this equation is already in slope intercept form you can see its 7.

The formula: y=mx+b is a formula to identify the slope and y-intercept.

The m indicates the slope and the b indicates the y-intercept.

LAST QUESTION PLEASE HELP IF YOU CAN FOR 11 POINTS AND BRAINLIEST + THANK YOU
jekas [21]

Answer:

  see attachment

Step-by-step explanation:

The y-intercept is +4 for both lines, so only the third selection is appropriate. The lines appear to have a slope of magnitude less than 1, so ±1/2 seems about right.

(We expect at least one of the inequality symbols to include the "or equal to" case so there is no hole at x=0. Alas, it seems the third answer choice doesn't do that.)
