We need to think, 28 / 42 = x / 54.
We need to do a proportion for this problem!
First, line up both fractions, then put a equal sign between both fractions.
28 / 42 = x / 54.
We multiply in a diagonal and then we divide by the one without a diagonal.
28 and 54 are a diagonal.
We multiply both numbers!
54 x 28 = 1,512.
Then, we divide by 42.
1,512 / 42 = 36.
Therefore, x = 36.

The first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42
Answer:
1.25 x 10^2 times greater.
or
125 times greater.
Step-by-step explanation:
The required ratio is 5 x 10^7 / 4 x 10^5
= 5/4 * (10^7 / 10^5)
= 1.25 x 10^2 greater.
Answer:
21 feet and 7 inches
Step-by-step explanation:
I multiplied 6 by 12 twice to find out how many inches she needs for the sides of the ladder which got me 154 then i multiplied 7 by 15 which got me 105 then i added the two products together and got 259 then i divided 259 by 12 to find out how many feet were in 259 inches which got me 21 with a reminder of 7
Therefore, the answer is 21 feet and 7 inches
