Terrance is making a scale model of a

Tanya [424]

Answer:

6.4 inches

Step-by-step explanation:

We are going to have to use ratio's here. We know that 1 inch = 2.5 feet and we know that Terrance is making a scale model of a car that is 16 feet long. We need to work out the length of the car in inches so,

1 inches = 2.5 feet

? inches = 16 feet

→ We are going to divide 16 by 2.5 and then multiply that answer by 1 to get our result so

16 ÷ 2.5 = 6.4

6.4 × 1 = 6.4

The final answer is 6.4 inches

A scale model of a tower is 24 inches tall and 18 inches wide. If the height of the actual tower is 60 feet, what is its width?

alex41 [277]

Answer:

45 feet

Step-by-step explanation:

To find the width of the model, we need to find the scale of the model to the actual tower.

Since we know the height of both towers, we can use that as the basis.

24 inches : 60 feet

12 inches : 30 feet

6 inches : 15 feet

So the width of the tower is 18 inches wide.

18 inches will then be equal to 12 + 7 inches : 30 + 15 feet

18 inches : 45 feet

I will mark you as brainlis if you andwer this all.

Answer: See below

Step-by-step explanation:

27. -(a-3)

28. (b-1)(b+3)

29. (c+4)(c+5)

30. d(d+5)

31. -(3/4)(2e-5)

Sorry - I don't have time to enter the details. Look for areas where the expressions can be factored in a manner that forms as many equivalent expressions in both the numerator and denominator.

For example: In problem 30:

(5d-20)/(d^2+d-20) * [??]/20d = 1/4

Factor:

<u>(5(d-4))</u> <u>d(d+5)</u> = 1/4

(d-4)(d+5<u>)</u> 20d

The (d-4), d+5, and d terms cancel, leaving

5/20 = 1/4
