1. you have to figure out what 3/4 of Ella's time is.
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
3. Next you are going to divide 1.6 by .75
4. Now multiple 2.13 by 5.
Answer is 10
3.14(3(2) + 3(4))
3.14( 6 + 12)
3.14(18)
=56.52
Ansley should invite a minimum of 15 guests.
$500 - $130 = $470 / 25 = 14.8 but she needs to be over the amount so
15 guests is the answer
I hope this helps :)
So you already have the formula for calculating the dosage for child with: C = a/(a+12)x 180 ml Not sure why you have double brackets
variables are: a = child's age, so everywhere you have an "a" replace it with the age of child.
Example: 5 year old child
C = 5/(5+12)*180= 5/(17)*180 = 5/3060 = .0016 ml or milligrams
I got 16.8 , but she’ll need roughly 17 gallons of paint :)
how i did it :
1. so you know she’ll need 4/5 per book case, and there are 16 bookcases.
2. So you do 16 x 5, then you get 84
3. and you divide 84 by 5. and you’ll get 16.8, that’s how many gallons of paint she needs
