Percent increase = (new number - original number) / original number...* 100
= (42 - 20) / 20....* 100
= 22/20 * 100
= 1.1 * 100
= 110 % increase
You can figure this out by doing a proportion:
4.5 pages x pages
---------------- = ---------------
36 minutes 60 minutes(1 hr)
*makes sure that because they are giving you time in minutes that you convert the hour to minutes. also you need to always remember to line up the same factors like in this case line up the pages and the time.
36x = 4.5(60)
36x = 270
x = 270/36
x = 7.5 pages
hope this helps :)
Answer ↣ 12 gallons per minute
Step-by-step explanation ↣ Ok I'm gonna use ratios because I can't draw a graph here.
Ok so if the garden hose supplies 36 gallons of water in 3 minutes, then the ratio is 36:3 because every 3 minutes the garden hose "sprays" 36 gallons.
To simplify this ratio, you need find the amount of water the garden hose supplies in 1 minute.
Well to get from 3 to 1, you have to divide by 3.
Do the same thing to 36. 36/3 equals 12.
So the final ratio is 12:1
This is the unit rate. The unit rate is when one variable is 1 unit (most of the time it is speed).
You can multiply 1 by any number and multiply 12 by the same number.
Here are some ratios...
m=minutes
g=gallons
1m:12g
2m:24g
3m:36g
4m:48g
5m:60g
Hope this helped!
