Answer:

<h2>       H ≈ 10.994424 m ≈ 11 m</h2>

Step-by-step explanation:

V=\pi R^2\cdot H\\\\V=13\,816\ m^3\\R=20\,m\\H=??\\\\13\,816=\pi\cdot20^2\cdot H\\\\13\,816=400\pi H\\\\13\,816\approx1256.637 H\\\\H\approx10.994424\,m

In Walmart parking, there are 175 vehicles parked joe figures out that 64% of the vehicles are white. How many vehicles are NOT
aksik [14]

Answer:

63 vehicles are not white

Step-by-step explanation:

Well you know that there are 175 total vehicles, and that 64% of those vehicles are white.  Therefore the remaining percentage of vehicles must not be white.

100%-64%=36%

This means that 36% of the vehicles aren't white.

Now you must find what 36% of 175 is.  The word "of" always signals for multiplication, which is exactly what you need to do here.  First start by converting the percentage into decimal form:

36%=0.36

Now you can multiply

175 x 0.36 = 63

63 Vehicles are not white

What is the slope of the line that passes through the point (-9,8) and (-3-1)?
natulia [17]

Answer:

Step-by-step explanation:

(x₁, y₁) = (-9 ,8)   and (x₂ , y₂) = (-3 , -1)

Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-1-8}{-3-[-9]}\\\\=\dfrac{-9}{-3+9}\\\\=\dfrac{-9}{6}\\\\=\dfrac{-3}{2}

Rewrite the equation 6x + 7y = 14 into slope-intercept form (y = mx + b)
Tamiku [17]

rearrange into the form y = mx + b

subtract 6x from both sides of the equation

7y = - 6x + 14

divide all terms by 7

y = - \frac{6}{7} x + 2 → in slope- intercept form
