at the point, 60°+x+45=360°
x=255°
Answer:
one-third of a gallon is in the bucket
Step-by-step explanation:
I think the answer is 14.
the smallest common multiple of 6 and 9 is 18. all multiples of 18 is divisible by 6 and 9.
500 ÷18=27.777777777
there are 27 numbers between 1 and 500 that are divisible by both 6 and 9, but when the quotient is an even number, the multiple of 18 is divisible by 4 as well, so only the multiples of 18 that produce an odd quotient satisfy the requirement.
from 1 to 27, there are 14 odd numbers.
Answer:
7.5
Step-by-step explanation:
Rate of fill-up = 1/44 = 1/44 * 77/77 = 77/3388
Rate of emptying = 1/77 = 1/77 * 44/44 =44/3388
Combined Rate of Fill-up = 77/3388 - 44/3388 = 33/3388 = 3/308
Time for combined fill-up = 308/3 = 102.6667 hours = 102 hours and 40 minutes
