It would be 1/3 because there are three ingredients. Therefore, if he is allergic to one of everything in each category, there are 3/10 things he is allergic to.
Answer: c. 1/2 /4
Step-by-step explanation:
There is a 1/2 gallon of milk.
This 1/2 gallon is pour in equal amounts into 4 small containers which means the 1/2 gallon was divided into 4 places.
Formula is therefore:
= 1/2 ÷ 4
= 1/2 /4
When solved you will get a result of:
= 1/8 gallons
Answer:
720
Step-by-step explanation:
468 = 65% of the original price
So,
468÷ 0.65 = 720 $. Just to be sure 720*0.35 = 468
You have two unknown rates, so we need to develop two equations to solve for these unknowns (based on the information given on the problem statement):
5x + 10y = 725
x + y = 100
By substitution, we get:
5x + 10(100 - x) = 725
5x + 1000 - 10x = 725
-5x = 725 - 1000
-5x = -275
x = -275/-5 = 55
100 - 55 = 45
Thus:
The mechanic who worked for 5 hours charged his time at $55/hr, and the mechanic who worked for 10 hours charged his time at $45/hr.
To verify, plug and chug the results back into the original equations:
5(55) + 10(45) = 725
275 + 450 = 725
725 = 725 [OK]
55 + 45 = 100 [OK]
