A cylinder has a volume of 390 cm³. If a cone has the same dimensions as the cylinder then what is the volume of the cone.

Mathematics
1 answer:
dangina [55]3 years ago
8 0

Answer: The volume of the cone is 130 cubic centimeters.

Step-by-step explanation:

We know that to find the volume of a cylinder you will use the formula

V= \pir^{2} *h  Where r is the radius and h is the height.

And to find the volume of a cone you will use the formula

V= \pir^{2}*h /3

So if they have the same dimensions which is the height and the radius then we will just divide the  volume of the cylinder by 3 to find the volume of the cone.

V = 390/3

V =  130 cm^3

Find the gradient and y- intercept of the line with equation 2x+3y-7=0
GaryK [48]

Answer:

Gradient = -2/3

y-intercept = 7/3

Step-by-step explanation:

Convert the equation in y = mx + c form, m is the gradient and c is the y-intercept

2x + 3y = 7

3y = -2x + 7

y = -2/3x + 7/3

I need to solve this system of equations, how do I do that?<br> 3x-4y=20<br> y=3/4x-5
Paha777 [63]

Answer:

Is is Infinitely many solutions so 0=0

<em><u>Step-by-step explanation:</u></em>

<h3>First we have to rearrange/simplify the equations:</h3>

Equation 1: 4y - 3x = -20

Equation (2):  y - 3x/4  = -5

<h3>Then you remove the fractions by multiplication: </h3>

Multiply equation (2) by 4

<h3>The Equations now look like this: </h3>

Equation 1: 4y - 3x = -20

Equation (2): 4y - 3x = -20

<h3>Solve for y on Equation (2):</h3>

y = <u><em>3x/4 - 5</em></u>

<h3>Then plug in this for the y in Equation 1 and then solve:</h3>

4•(<u><em>3x/4-5</em></u>) - 3x = -20

Therefore the answer leads to:

Infinitely many solutions, 0=0

Hope this helped :')

Write the slope-intercept form (y=mx + b) of the blue line. Explain or show your work. Write a one sentence summary comparing th
viktelen [127]

Answer:

Therefore, the slope-intercept form of the blue line is

y = \frac{1 }{2}x + 2

Comparison:

The blue and black lines both have equal y-intercept but different slopes.

The black line is steeper than blue line which means the black line has a greater slope than the blue line.

Step-by-step explanation:

Please refer to the attached graph of this question where we have two straight lines.

The slope-intercept form is given by

y = mx + b

Where m is the slope of the line and b is the y-intercept.

Let us find the slope of the blue line from the points given in the graph.

(x_1, y_1) = (0,2) \\\\(x_2, y_2) = (4,4) \\\\

The slope is given by

m = \frac{y_2 -y_1 }{x_2 -x_1}  \\\\m = \frac{4 -2 }{4 -0}  \\\\m = \frac{2 }{4}  \\\\m = \frac{1 }{2}  \\\\

The y-intercept is given by

y = \frac{1 }{2}x + b  \\\\2 = \frac{1 }{2}(0) + b  \\\\b = 2

Therefore, the slope-intercept form of the blue line is

y = \frac{1 }{2}x + 2

Comparison:

The blue and black lines both have equal y-intercept but different slopes.

The black line is steeper than blue line which means the black line has a greater slope than the blue line.
