Answer: B. Circle

Step-by-step explanation:

Since the base is a rectangle and the faces are rectangular, there is no way to slice the prism to get a a circle.

The trapezoid ? Maybe. A diagonal slice starting on a corner will create a quadrilateral with uneven sides.

Pentagon? Imagine starting on the top near a corner-- but not on the corner-- with a diagonal line, slicing down towards the opposite corner. You should be able to get an irregular pentagon.

A rectangle is easy!

No circles!

Enjoy! I hope this helps you.

Answer:

The answer is option B.

Step-by-step explanation:

Since it's a rectangular prism slicing will produce either a rectangle or trapezoid and not or a circle since it's round

Hope this helps you

If it takes 16 yards of material to make 5/2 costumes, how much material will be needed to make 19/2 costumes of that same size?
IRISSAK [1]

yards/costumes:16/(5/2) = X/(19/2)

Cross multiply.

(5/2)x = 152

Multiply both sides by 2/5.

x = 101 1/3 yards

The formula for the volume of a pyramid is V=(1/3) ⁢B⁢h, where B is the area of the base and h is the height. Rearrange the form
PIT_PIT [208]
To make an equation that solves for the height as according to the volume of a pyramid, you must isolate the variable h on one side.

The first thing you have to do is to multiply both sides by 3 to get 3V=Bh.

Then, divide both sides by B to get your answer as h=3V/B.

What is the answer too 2(4w-1)=-10(w-3)+4
Advocard [28]

Answer:

w = 2

Step-by-step explanation:

 2(4w - 1) = -10(w - 3) + 4

 8w - 2 = -10w + 30 + 4

 8w - 2 = -10w + 34

+10w       +10w

18w - 2 = 34

      +2     +2

<u>18w</u> = <u>36</u>

18       18

w = 2

Which of the following is an equation of the line through (2,3) and (-1,-12)
ahrayia [7]

Answer:

y = 5x - 7

Step-by-step explanation:

Using the equation of a line with two points

y_2 - y_1 / x_2 - x_1 = y - y_1 / x - x_1

Giving two points

( -4 , 10)(16 , -2)

x_1 = -4

y_1 = 10

x_2 = 16

y_2 = -2

Using the above formula

y_2 - y_1 / x_2 - x_1 = y - y_1 / x - x_1

-12 - 3 / -1 - 2 = y - 3 / x - 2

-15/-3 = y - 3 /x - 2

Cross multiply

-15(x - 2) = -3(y - 3)

-15x + 30 = -3y + 9

-15x + 30 + 3y - 9 = 0

-15x +30 - 9 + 3y = 0

-15x + 21 + 3y = 0

3y = 15x - 21 ( following y = mx + C

Dividing through by 3 to find y

3y/3 = 15x -21 / 3

y = 15x - 21 / 3

We can still separate

y = 15x / 3 - 21/3

y = 5x - 7

Therefore, the equation of the line is

y = 5x - 7
