1188 = π<em>r</em>²<em>h</em>

For the formula to solve for <em>h, </em>you have to change the equation to:

<em>h </em>= 1188/π<em>r</em>²

which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.

because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)

Since you don't know the radius, you can't simplify this equation.

The answer is <em>h </em>= 1188/π<em>r</em>²

It`s either 100,000 because there is only four 0`s making it 70,000 or it`s 700,000 and you made a mistake of not typing that last zero in which case the question would be pointless to ask because the answer is in the question.

PLEASE ANSWER THIS QUESTION! I BEG OF YOU
Law Incorporation [45]

The difference between the rate of change of B and the rate of change of A is 15.

<h3>How to get the difference in the rates of change?</h3>

First, we need to get the two rates of change.

We have two linear functions.

A: y = 35*x

For function A the rate of change is the slope, wich is 35.

Function B is graphed.

Remember that if a line passes through two points (x₁, y₁) and (x₂,y₂) then the slope is:

a = \frac{y_2 - y_1}{x_2 - x_1}

In the graph, we can see that line B passes through (0, 0) and (1, 50), then the slope is:

a = \frac{50 - 0}{1 - 0} = 50

Then the rate of change of B is 50.

The difference between the rates of change is:

diff = 50 - 35 = 15

Solve |2x - 5| = 4 someone help
ss7ja [257]

\text{Solve the absolute value, remember, there are two answers/outcomes}\\\\\text{First outcome:}\\\\2x - 5 = 4\\\\\text{Solve:}\\\\2x - 5 = 4\\\\\text{Add 5 to both sides}\\\\2x=9\\\\\text{Divide by 2}\\\\\boxed{x=\frac{9}{2}}\\\\\text{Second outcome:}\\\\2x - 5 = -4\\\\\text{Add 5 to both sides}\\\\2x=1\\\\\text{Divide by 2}\\\\\boxed{x=\frac{1}{2}}

368%

<em>convert to a fraction</em>

\frac{368}{100}

<em>divide top and bottom by 2</em>

<em />\frac{184}{50}<em />

<em>divide top and bottom by 2</em>

<em />\frac{92}{25}<em />

92/25 = 3 remainder 17
