Answer:
905 - 825 = 80
that means 80 min is between those times,
80 min = 1 hr and 20 min
*WARNING THIS WILL NOT WORK FOR SOME QUESTIONS, I AM DOING A SHORTCUT WAY!!*
Answer: <u><em>1 hr and 20 min has passed from 8:25 to 9:05. </em></u>
Part A:
10p + 12v > 3200
p > 12000
v < 15000
(imagine they have the line underneath the symbols)
Part B:
at least 14,000 cups of plain yogurt
(make sure to convert the dollars to cents so that it is accurate)
math:
10p + 12(15000) > 320000
10p > 140000
p > 14000
Answer:
Step-by-step explanation:
The lengths can be found by considering their ratio:
short : long = 1 : 5
The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.
The lengths are ...
1 : 5 = 24 in : 120 in
The pieces are 24 inches and 120 inches in length.
__
Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...
s +5s = 144
s = 144/6 = 24
5s = 5(24) = 120
The lengths are 24 inches and 120 inches.
