What is the value of x? -5x = 60

Step2247 [10]

Answer:

x = -12

Step-by-step explanation:

⇒ -5x = 60

Isolate the variable "x" by dividing by -5 on each side.

⇒ -5x/-5 = 60/-5

⇒ x = -12

The solution is x = -12

The formula for the volume V of a cylinder is LaTeX: V=\pi r^2hV = π r 2 h, where r is the radius of the base anThe formula for

Alekssandra [29.7K]

Answer:

$h = \frac{V}{\pi r^2}$

$h = 4 cm$

Step-by-step explanation:

Volume of cylinder is given as $V = \pi r^2 h$

V is the volume the cylinder, r is its radius at the base, while is its height.

To select the formula for h (height) let's make h the subject of the formula as follows:

$V = \pi r^2 h$

$\frac{V}{\pi r^2} = \frac{\pi r^2 h}{\pi r^2}$ (dividing both sides of the equation by $\pi r^2$ )

$\frac{V}{\pi r^2} = h$

$h = \frac{V}{\pi r^2}$

Use the formula above to find the height of the given cylinder where Volume (V) = 36π cm³, and base radius (r) = 3 cm:

$h = \frac{36 \pi}{\pi 3^2}$ (substitution)

$h = \frac{36 \pi}{\pi * 9}$

$h = \frac{36 \pi}{9 \pi}$

$h = \frac{36 \pi}{\pi * 9}$

$h = \frac{36}{9}$ ( $\pi$ cancels $\pi$ )

$h = 4 cm$

What is the value of x? 20 35 60 70

agasfer [191]

I think it’s a 20 but I’m not sure you should use a protractor to measure it and look at the angles and then look how much to add 40 with the value of the X to get your answer good luck!
