Answer:
$90,958.61
Step-by-step explanation: I THINK
So it took him 4/5 of an hour to paint 1/3
that means there is still 2/3 to go
so that means that he will have two times that time to paint the rest of the room
<u>4/5</u> = <u> ? </u>
1/3 2/3
using cross multiplication
(4/5)(2/3) = (1/3) (?)
8/15 = 1/3 ?
divide both sides by 1/3
so that will be 8/5
that means it will take 8/5 of an hour to complete the rest
or 12/5 total to do entire room
Hope this helps ;)
Order is important in ratios so in this one, it says the ration from GIRLS to BOYS.
We know there are 12 girls and 9 boys so the ratio is B. 12:9
114
Just use the Pythagorean theorem and then multiply by 2 to find answer. See picture to see how I did it.
