Sovle for h: v=1/3πr²h

Mathematics
1 answer:
erastovalidia [21]3 years ago
8 0

Answer:

<h2>h = \frac{3v}{\pi {r}^{2} }</h2>

Step-by-step explanation:

v =  \frac{1}{3} \pi {r}^{2} h

To solve for h multiply through by 3 to eliminate the fraction

That's

3v = \pi {r}^{2} h

Divide both sides by πr² to make h stand alone

\frac{\pi {r}^{2} h}{\pi {r}^{2} }  =  \frac{3v}{\pi {r}^{2} }

We have the final answer as

h = \frac{3v}{\pi {r}^{2} }

Hope this helps you

Find two consecutive even integers such that the square of the second, decreased by twice the first is 52
Fiesta28 [93]

Let the first integer be x. So, the next even number is x+2

Let's translate the formula: the square of the second is (x+2)^2, twice the first is 2x. So, the equation is

(x+2)^2 - 2x = 52

Expand the square to get

x^2+4x+4-2x = 52 \iff x^2+2x+4 = 52 \iff x^2+2x - 48 = 0

The solutions to this equations are

x = -8,\quad x = 6

So, the possible consecutive even numbers are

-8\text{ and } -6\quad\text{or}\quad 6\text{ and } 8

Can someone please help me with question 3
Anastasy [175]

Answer:

8.55 inches tall

Step-by-step explanation:

equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.

Now plug in 4.6 for t you get:

h = -0.75t + 12

h = -0.75(4.6) + 12

h = -3.45 +12

h = 8.55 inches tall
