Answer: A. 20%

Step-by-step explanation:

First, to find the total number of teachers, we can add 25+32+18+5+20=100

Next, we divide the number of teachers in 2014 (20) by the total number of teachers (100) as follows:

20 ÷ 100 = 0.2

Finally, to make 0.2 a percentage, we can multiply 0.2 X 100 = 20

Therefore, the correct answer is A.

Answer:

The slope intercept form is $y=\frac{1}{2}x-5$

Step-by-step explanation:

Given : Equation $y+3=\frac{1}{2}(x-4)$

To find : Rewrite the equation in slope-intercept form ?

Solution :

The slope-intercept form is $y=mx+c$

Equation $y+3=\frac{1}{2}(x-4)$

$y+3=\frac{1}{2}x-\frac{1}{2}\times 4$

$y+3=\frac{1}{2}x-2$

$y=\frac{1}{2}x-2-3$

$y=\frac{1}{2}x-5$

Therefore, the slope intercept form is $y=\frac{1}{2}x-5$

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?

Marysya12 [62]

Due to given condition we can conclude:
H = 2D
where D is diameter of base and H height of cone

Volume of cone is calculated by:

V = B*H = r^2*pi*H

Now we need to express H in terms of r. H = 2D = 2*2*r because D = 2r
V = r^2*pi*4r = 4r^3*pi

Answer:

20√2

Step-by-step explanation:

It is helpful to know your multiplication facts. For simplifying the radicals, you remove the perfect squares:

$\sqrt{a^2\cdot b}=a\sqrt{b}$

$-3\sqrt{18}+5\sqrt{72}-\sqrt{2}=-3\sqrt{3^2\cdot2}+5\sqrt{6^2\cdot2}-\sqrt{2}\\\\=-3\cdot3\sqrt{2}+5\cdot6\sqrt{2}-\sqrt{2}=(-9+30-1)\sqrt{2}\\\\=\boxed{20\sqrt{2}}$
