Answer:
Step-by-step explanation:
Sean buys some T-shirts for $12 each and the same number of belts for $7.50 each. Write an expression in the simplest form that represents the total amount.
So n represents the same number for t-shirts and belts.
Therefore n x 12.50 + n x 7.50 OR n(12.50+7.50)
The problem the student made was that they multiplied 12 times n plus 7.50. They forgot to multiply n times 7.50.
An expression that represents the total amount spent is 12n + 7.50n
Hope this helps!
Regular pay = $9.40
Overtime pay = 9.4 x 1.5 = $14.10
1 hour = 14.10
5 hours = 14.10 x 5 = $70.50
1 employee = $70.50
200 employees = 70.50 x 200 = $14100
Lets write formulas for volume of both cone and can
Cone:
Vc = Bc*Hc/3
Can:
V = B*H
where B is basis and H is height for each
Now because cone fits perfectly inside can that means that both B and H are the same
from this we can see that cone has 3 times less volume than a can that cone is inside of.
if can has 36 volume that means that cone has:
36/3 = 12 volume
Answer is 12.

Answer:
540
Step-by-step explanation:
Amount of antifreeze in the 90% solution + amount of antifreeze in the 20% solution = amount of antifreeze in the 80% solution
0.90 x + 0.20 (90) = 0.80 (x + 90)
0.90 x + 18 = 0.80 x + 72
0.10 x = 54
x = 540
You need 540 gallons of 90% antifreeze solution.
