Which pair of ratios will make a proportion

1 answer:

6 0

The answer would be C. If you simplify the 12/9 by 3 it would simplify to be 4/3 and 4/3 = 4/3. You can also cross multiply 4/3 = 12/9. 4(9) = 12(3) both would equal 36 so they would be proportional.

Ello bruv... can y'all help me!:

Phoenix [80]

(C)

Step-by-step explanation:

We are going to use the following conversions for this problem:

1 km = 1000 m

1 hr = 60 min

The key is to multiply the given quantity with factors such that the unwanted units cancel out, leaving only the ones we need. In this case, we need meters and minutes. The set up goes like this:

$8\dfrac{\text{km}}{\text{hr}}×\dfrac{1000\:\text{m}}{1\:\text{km}}×\dfrac{1\:\text{hr}}{60\:\text{min}}$

The length of a rectangle is four more than twice its width. The perimeter is 116 in. Find the length of the rectangle.

Marat540 [252]

Answer:

Length is 38.7

Width is 19.3

4x length to 2x width

4+2=6

6x =116

x = 58/3

4 x 58/3 = 77.3

2 x 58/3 = 38.7

4:2

2:1

77.3/2 = 38.7

38.7/2 = 19.3

38.7 + 38.7 + 19.3 + 19.3 = 116
