Eric earned 60 points on his last test if there were 75 possible points what was his percent grade

Answers

So 75 points is your 100%. You can do 60 over 75 is equal to X over 100. You divide your numerator(60) by your denominator(75) to get 85.7142857%, or to round to your nearest percent, your answer would be roughly 86%.

THE VOLUME OF A CONE IS 15 PI CUBIC METERS. WHAT IS THE VOLUME OF A CYLINDER HAVING THE SAME BASE AND SAME HEIGHT?

Answers

Okay, so I know that you either multiply the volume of a cone by 3 to get the cylinders volume, or you divide it. I think you multiply it. Just remember, the rule is to multiply the volume of a cone by 3, to get the cylinder volume with the same measurements. So 15 x 3.

Final answer:

To find the volume of a cone and a cylinder with the same base and height, use the formulas for volume of a cone and volume of a cylinder. Solve for r^2 * h in the cone's volume formula, then use this value in the cylinder's volume formula.

Explanation:

To find the volume of the cylinder with the same base and height as the given cone, we need to know the formula for the volume of a cone and the formula for the volume of a cylinder. The volume of a cone is given by the formula V = 1/3 * π * r^2 * h, where r is the radius of the base and h is the height of the cone. Since the cone has a volume of 15π cubic meters, we can set up the equation 15π = 1/3 * π * r^2 * h and solve for r^2 * h. Once we have r^2 * h, we can use the formula for the volume of a cylinder, V = π * r^2 * h, to calculate the volume of the cylinder.

, let's solve the equation 15π = 1/3 * π * r^2 * h for r^2 * h:

15π = 1/3 * π * r^2 * h

Multiplying both sides of the equation by 3, we get:

45π = π * r^2 * h

Canceling out the π on both sides of the equation, we get:

45 = r^2 * h

Now we have r^2 * h, which is 45. Let's plug this value into the formula for the volume of a cylinder, V = π * r^2 * h:

V = π * 45

So the volume of the cylinder with the same base and height as the given cone is 45π cubic meters.

state whether the lines represented by the equations y=1/2x-1 and y+4=-1/2(x-2) are paraller, perdendicular, or neither

Answers

The lines represented by the equations y=1/2x-1 and y+4=-1/2(x-2) are neither parallel nor perpendicular.

What is an equation?

An equation is slope-interceptthat shows the relationship between two or more numbers and variables.

The first equation y=1/2x-1 is already in the slope intercept form. The slope is, 1/2, and the y-intercept is -1.

The second equation y+4=-1/2(x-2)

From this equation, the slope is -1/2 and the y-ina tercept is -3.

When two lines ara e parallel, they have the same slope. one has slope of 1/2 and the other has slope of -1/2 thus these are not the same our lines are not parallel.

When lines are perpendicular, the slope of one is the negative reciprocal of the other which is not satisfied in the given equations.

Thus, we conclude that the lines represented by the equations y=1/2x-1 and y+4=-1/2(x-2) are neither parallel nor perpendicular.

#SPJ2

The easiest way to tell whether lines are parallel, perpendicular, or neither is when they are written in slope-intercept form or y = mx + b. We will begin by putting both of our equations into this format.

The first equation, y =  (1)/(2)x - 1 is already in slope intercept form. The slope is 1/2 and the y-intercept is -1.

The second equation requires rearranging.
y + 4 =  -(1)/(2)(x - 2) \n y + 4 = -(1)/(2)x + 1 \n y = - (1)/(2) x- 3
From this equation, we can see that the slope is -1/2 and the y-intercept is -3.

When lines are parallel, they have the same slope. This is not the case with these lines because one has slope of 1/2 and the other has slope of -1/2. Since these are not the same our lines are not parallel.

When lines are perpendicular, the slope of one is the negative reciprocal of the other. That is, if one had slope 2, the other would have slope -1/2. This also is not the case in this problem.

Thus, we conclude that the lines are neither parallel nor perpendicular.

B. 72s cu units
C. 365 cu. units
D. 108 cu. units

Answers

The value of volume of the sphere shown with a radius of 3 is,

⇒ 36π units³

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Since, We know that;

volume of the sphere is,

V = 4/3π × r³

Here, We have;

r = 3

Hence, We get;

V = 4/3π × 3 × 3 × 3

= 4/3π × 27

=36π

Thus, The value of volume of the sphere shown with a radius of 3 is,

⇒ 36π units³
