Answer:
E. 18 children are buying their lunches
F. Rock must pay $50 each month
Step-by-step explanation:
E.
To find a percentage you multiply the number by the percentage;
60 x 70%(0.70) = 42 children brought their lunches
But we need the amount <u>buying</u> their lunches so we would subtract 60 by 42;
60 - 42 = 18 buying their lunches
F.
Again, to find the percentage we multiply it by the original;
$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa
Now we need to find how much Rock still needs to pay for the sofa;
$800 - $200 = $600 more needed to pay for the sofa
Lastly, we must find how much Rock will need to pay <u>each month</u> to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;
$600 / 12 = $50 needs to be paid each month for a year
The sum of the lengths of two shorter sides of a triangle must be greater than the length of the longest side.
The answer is D.

Answer:
6 minutes 8 balloon animals. 45 minutes 60 balloon animals!
Step-by-step explanation:
I divided 15 by 6 and got 2.5, so I then divided 20 by 2.5 and got 8 balloon animals! For the next one I divided 45 by 15 and got 3 then I multiplied 20 by 3 and got 60 balloon animals! Hope this helps!
Answer:
Step-by-step explanation: Part 1) The units rates are
A)
B)
C)
D)
Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume
Part 1) Calculate the unit rate for each size
case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction
Find the unit rate
case B) we have
18 2/2 oz. bottle costs $1.49
Convert mixed number
Find the unit rate
case C) we have
48 1/4 oz. carton costs $2.49
Convert mixed number to an improper fraction
Find the unit rate
case D) we have
64 3/4 oz. carton costs $3.75
Convert mixed number to an improper fraction
Find the unit rate
Part 2) which size is the best buy
we know that
The best buy is the one with the smallest unit rate
so
The best buy is the size 48 1/4 oz
