200 + 20x ≥ 500 I don't get these
Vikentia [17]

Answer:

x ≥ 15

Step-by-step explanation:

200 + 20x ≥ 500

To solve this inequality, you must first subtract 200 from 500.

500 - 200 = 300.

Lastly, divide 300 by 20.

20x = 300

300 ÷ 20 = 15

Therefore, the value of x is 15.

The volume of a cylinder is 525 cm3. The radius of the base of the cylinder is 5 cm. What is the height of the cylinder? The hei
elena-14-01-66 [18.8K]

you do not give a value for PI so I am using 3.14

V=PI x r^2 x H

you know volume and radius so put those into the equation

525 = PI (3.14) x 5^2 x H

525 = 3.14 x 25 x H

525 = 78.5 x H

divide both sides by 78.5

6.687 = H

round off answer as needed 6.7cm or 6.69cm

 NOTE : the answer may vary slightly depending on the value of PI used.

 but this is how you calculate the height.

Answer:

-1/2

Step-by-step explanation:

x_{1}=-7 \ ; \ y_{1}=-4\\\\x_{2}=-11 \ ; \ y_{2} = -2\\\\\\Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\dfrac{-2-[-4]}{-11-[-7]}\\\\\\=\dfrac{-2+4}{-11+7}\\\\\\=\dfrac{2}{-4}\\\\\\=\dfrac{-1}{2}
