You are using a 9 inch paint roller to paint a wall of your bedroom. The roller has a dimension of 1 5/8 inches and a nap thickness of 1/4 inch, as shown

Answers

Answer:

21.38 square inches

Step-by-step explanation:

Given that You are using a 9 inch paint roller to paint a wall of your bedroom. The roller has a dimension of 1 5/8 inches as diameter and a nap thickness of 1/4 inch, as shown

The nap is the fuzzy materials on the surface roller. How much area does the roller cover in one full revelation

The parameters to be considered are:

Diameter = 15/8 inches

Thickness = 1/4 inches

After one revolution rolling, the dimensions of the length will be:

L = 1/4 + 15/8 + 1/4

L = 19/8 inches.

Let the width be equal to 9 inches

The area covered = L × W

Substitute L and W into the formula

Area = 19/8 × 9

Area = 21.38 square inches

Therefore, the area covered by the roller in one full revelation is 21.38 square inches

Anyone know how to do this?? Help pls

Answers

Answer:

The correct answer is A. a = 2s - b - c

Step-by-step explanation:

First you multiply 2 on both sides and you will end up with 2s = a + b + c.

Then to isolate a you would subtract both b and c from both sides of the equation as well to end up with your answer of a = 2s - b - c.

Rectangle PQRS is rotated 90° counterclockwise about the origin to create rectangle people are P prime Q prime R prime S prime . What are the coordinates of point R prime

Answers

Answer:

R'(4, -1)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and reflection.

If a point A(x, y) is  rotated 90° counterclockwise about the origin, the new point is A'(-y, x)

From the image attached, below are the location of the points:

P(-3, -1), Q(-1, -1), R(-1, -4) and S(-3, -4)

If point R(-4, -1) is rotated 90° counterclockwise about the origin, its new location would be at R'(4, -1)

Determine whether the equation is always, sometimes, or never true. 6(x + 1) = 2(5 + 3x)

Answers

Answer:

never true

Step-by-step explanation:

6(x + 1) = 2(5 + 3x)

distribute

6x + 6 = 10 + 6x

combine like terms by subtracting 6x and 6 from both sides

0 = 4

that is not a true statement, so this equation is never true
