X = 25
Y = 10.8
All I did is divide 30 by 50 which is .6 then I multiple by 18 which is 10.8 for y. Then 15 divided by .6 equals to 25

Can someone please explain how to do this? thank you!
valkas [14]

Answer:

I belive the answer would be 452.16

Step-by-step explanation:

The formula to find the volume of a cylinder is v=\pi r^2h

h = height

r = radius

The radius for this is 4 and the height is 9

instert your number into your equation v=\pi (4)^2(9)

and from there i would just put it into a calculator and you get 144\pi or 452.3893-

Please help <br> Find the value of x
jeka57 [31]

Answer:

54

Step-by-step explanation:

The sum of given angles must be equal to 360°

3x° + 2x° + 90° = 360°

5x + 90 = 360

5x = 270 divide both sides by 5

x = 54

Which is the equation in slope-intercept form for the line that passes through (-2, 15) and is perpendicular to 2x + 3y = 4?
Ilya [14]

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x + 3y = 4 into this form

Subtract 2x from both sides

3y = - 2x + 4 ( divide all terms by 3 )

y = - \frac{2}{3} x + \frac{4}{3} ← in slope- intercept form

with slope m = - \frac{2}{3}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{2}{3} } = \frac{3}{2}, hence

y = \frac{3}{2} x + c ← is the partial equation of the perpendicular line

To find c substitute (- 2, 15) into the partial equation

15 = - 3 + c ⇒ c = 15 + 3 = 18

y = \frac{3}{2} x + 18 → B
