Tawnee is designing a playground in the shape of a rectangle. If Tawnee increases the length and width of the playground by a sc
svetlana [45]

Answer:

We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Step-by-step explanation:

We know that the perimeter of a rectangle = 2(l+w)

i.e.

P = 2(l+w)

Here

  • 'l' is the length
  • 'w' is the width

Given that the length and width of the playground by a scale factor of 2

A scale factor of 2 means we need to multiply both length and width by 2.

i.e

P = 2× 2(l+w)

P' = 2 (2(l+w))

    = 2P      ∵ P = 2(l+w)

Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

there are 8 uniforms at a fire station. Their total weight is 538 pounds. about how many pounds does each uniform Weigh? would y
earnstyle [38]

If 8= 538 Ib. then take the (538) and divide that by 8. <---- 8 for the 8 uniforms.

Your math should look like this: 538/8= about 67 pounds.

Then do 67*8= 536. (You started at 532 Ib.) this is just 2 pounds off*

So, your answer should be *67* pounds.

*Use paper and a pencil! Sometimes doing mental math can be challenging with a problem like this. So use paper and a pencil, checking your answer wont hurt either!*
