Marina CMI [18]3 years ago

Answer:

Perimeter is equal to all four sides added together.

Length = 3W; L=3W

So

P = 2(W) + 2(L)  substitute the equation for length above you get

P = 2(W) + 2(3W)  and combine

P = 2W + 6W = 8W; put in what the perimeter is and solve for W

66 = 8W, so W = 8.25

W = 8.25, L = 24.75

An architect creates a scale model of a building with a scale of 3 inches =11 feet of the actual width of the building is 121 fe
Tomtit [17]

Answer:

The width of the scale model is 33 inches.

Step-by-step explanation:

This question is solved making a relation with the scale model.

In the scale, 3 inches are worth 11 real feet.

The actual width of the building is 121 feet, so we find it's scale by a rule of three.

3 inches - 11 feet

x inches - 121 feet

11x = 121*3

Simplifying by 3, both sides

x = 11*3 = 33

The width of the scale model is 33 inches.

<h3>How much money does each payment option receive?</h3>

The payment options contemplated by the employer are distributed as follows:

Option A

  • First week: $200
  • Second week: $200 + $50 = $250
  • Third week: $250 + $50 = $300
  • Fourth week: $300 + $50 = $350
  • Fifth week: $350 + $50 = $400
  • Sixth week: $400 + $50 = $450

Option B

  • First week: $200
  • Second week: $220
  • Third week: $240
  • Fourth week: $260
  • Fifth week: $280
  • Sixth week: $300

50 points!!! please hurry
Margarita [4]

Answer:

It comes down to what the equals sign means. It means,  that the two things mentioned on either side of the equation are the same thing. If you do something to the left side, you have presumably changed it.

Step-by-step explanation:

Hope this helps, If it did, then I would really appreciate it if you gave me Brainliest, I only need one more to rank up and it has taken forever to get to where I am currently. Thanks.
