A shopping mall has a moving sidewalk that takes shoppers from the shopping area to the parking garage, a distance of 220 ft. If your normal walking rate is 5 ft/s and the moving sidewalk is traveling at 3 ft/s, how many seconds would it take for you to walk from one end of the moving sidewalk to the other end?

Answers

Answer 1
So you’d add 5 and 3 so it’s 8 ft/s

You then divide 220/8

So it should be 27.5 seconds.

Sorry about that other guy. Hope this helps!

what solution is -5m=8m-2

Answers

Answer:

m=2/13

Step-by-step explanation:

Given function:

-5m=8m-2

Subtract middle value from both side:

[tex]-5m-8m=8m-2-8m[/tex]

Combine like terms:

[tex]-13m=-2[/tex]

Divide both sides by the same term:

[tex]\frac{-13}{13}=\frac{-2}{-13}[/tex]

Divide the terms:

[tex]=\frac{2}{13}[/tex]

Therefore, m=2/13.

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?​

Answers

Answer:

The perimeter of the triangle can be expressed as 5x + 18.

Step-by-step explanation:

Perimeter of an object is the sum of the length of its sides.

For the required triangle, we have;

length of the base = x

length of the second side = 3x + 9

length of the third side = x + 9

Perimeter of the triangle = length of the base + length of the second side + length of the third side

                                        = x + (3x + 9) + (x + 9)

                                        = x + 3x + 9 + x + 9

                                        = 5x + 18

The perimeter of the triangle can be expressed as 5x + 18.

Answer:

  -24

Step-by-step explanation:

We can simplify this to ...

  b^2 +3(b -b^2) -2a

  = b^2 +3b -3b^2 -2a

  = -2b^2 +3b -2a . . . . . . . simplified form

This can be made easier for evaluation by factoring out b.

  = (-2b +3)b -2a

Using the given values, this is

parallelogram has vertices at (4,4), (7,4), (5,2), and (2, 2). The parallelogram is translated 7 units down and reflected across the y-axis. What are the coordinates of the first point of its image (4,4)?​

Answers

Answer:

Step-by-step explanation:

So we move the parallelogram down 7 units and get the coordinates: (-3,4) (0,4) (-2,2) (-5,2)

Then the equation for reflecting across the y-axis is (x,y) ---> (-x,y) Then I think you can solve it from there. Just take the x points and make them the opposite charge.
