Please help me ASAP this a test.!

20in = 70ft

10in = 35ft

Step-by-step explanation:

Since you know that every two inches is 7 feet, all I did was divided 20 by 2, to figure out how many pairs of two inches I had, which I have ten pairs. So now I know I can do 10x7, which gave me 70.

This is the same process for 10 feet, the only difference is there's 5 pairs of 2, therefore you can do 7x5.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

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.
