It would be 42 miles over 3 gallons
42/3=14
Hope this helps :)
So 1/12 of all dogs are in hound
of the hound gropu, 3/10 is english foxhounds
find what fraciton of all adogs are english foxhounds
so 3/10 of 1/12
in math 'of' means multiply with fractions so
3/10 times 1/12=(3 times 1)/(10 times 12)=3/120=1/40
1/40 of the dogs were english foxhounds
If you have two terms in a sequence, then a term decreased by the previous term=common difference
so
30 and 27
27 decreased by 30 is -3
the common differce is -3
Answer:
1/8
Step-by-step explanation:
1/2 cubed is just 1/2*1/2*1/2 which is 1/8
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]
