Which ratio would allow you to convert from 45 cm into feet? A. 1 inch/2.54 cm...because feet would cancel out B. 2.54cm/1 because cm would cancel out C. 2.54cm/1 inch...because in would cancel out D. 1 inch/2.54 cm...because cm would cancel out

The correct answer is 1 feet/2.54 cm because the cm would cancel out

Step-by-step explanation:

Here, we want the ratio that would allow us convert from 45 cm into feet.

The correct answer here is 1 feet/2.54 cm because the cm would cancel out, leaving us with the feet only.

It would be a case like;

1 feet/2.54 cm * 45 cm

So, we would have;

(45 cm * 1 feet)/2.54 cm

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
