Answer:

h = 3V/(πr²)

Step-by-step explanation:

You are asked to solve a one-step linear equation for h.

<h3>Solution</h3>

The "one step" is to divide by the coefficient of h.

$V=\dfrac{1}{3}\pi r^2h\qquad\text{given}\\\\\dfrac{V}{\dfrac{1}{3}\pi r^2}=\dfrac{\dfrac{1}{3}\pi r^2h}{\dfrac{1}{3}\pi r^2}\qquad\text{divide by the coefficient of h}\\\\\boxed{h=\dfrac{3V}{\pi r^2}}\qquad\text{simplify}$

<em>Additional comment</em>

The equation is "linear" because the variable of interest is h. It has an exponent (degree) of 1. The other "variables" are treated as though they were constants. The equation is conceptually no different from ...

2 = (5/3)h

which you solve by dividing by 5/3 (or multiplying by 3/5).

Which of the following is not an example of using the distributive property to multiply 12 times 22?

s2008m [1.1K]

That would be : 10(2 * 22)

because 12(20 + 2) = 12 x 22.....and 22(10 + 2) = 22 x 12
whereas, 10(2 * 22) = 10 x 44

Find the number of steel ball bearings, each of diameter 0.7 cm, that can be made from 1kg of steel, given that 1cm cubed of ste

liq [111]

Answer:

Ball Bearing Volume = (4 / 3) * PI * radius ^3

Volume = (4 / 3) * 3.14159265 * (.35)^3

Volume = (4 / 3) * 3.14159265 * 0.042875

Volume = 0.17959438 cc

1 cc of steel = 7.8 g

Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc

1 kg = 128.205 cc

Number of ball bearings we can make = 128.205 / 0.17959438

Equals 713.86
