Hey guys, I need help with these Scale factor problems! problems are linked in a screenshot below:
AVprozaik [17]

Answer:

  1. A → B: 1/3
  2. correct
  3. A → B: 2/5

Step-by-step explanation:

It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.

  1. A → B = 1/3; B → A = 3
  2. A → B = 2; B → A = 1/2
  3. A → B = 2/5; B → A = 5/2

__

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.

  1. B : A = 1 : 3
  2. A : B = 1 : 2
  3. B : A = 2 : 5

Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.

Stacy and Neil painted 280 ft of their living room wall with 4/5 gallon of paint. How many square feet can they paint with 3 gal
barxatty [35]

Step-by-step explanation:

4/5 gallons for 280 ft² (the ² is missing in the question ...).

3 gallons would be 15/5.

so, what do I need to multiply 4 with to get 15 ?

4×x = 15

x = 15/4

multiplying now also 280 ft² with this factor gives us the answer :

280 × 15/4 = 70 × 15 = 1050 ft²

they can paint 1050 ft² with 3 gallons of paint.
