Answer:
30 cans
Step-by-step explanation:
We can use ratios
15 cans x cans
---------------- = ------------------
7*2 people days 4*7 people days
Using cross products
15 * 28 = 14 * x
Divide by 14
15 * 28/14 = x
30 =x
Answer:
Step-by-step explanation:
12/24 reduces to 1/2, whereas 3/4 does not reduce. This pair of ratios does not form a proportion.
If both ratios reduced to the same common value, that would represent a proportion.
Answer:
93
Step-by-step explanation:
The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.
In this case, representing the eighth score with x, the mean is (611+x)/8
Solving for the mean:
88=(611+x)/8
Multiply both sides by 8
8*88=611+x
704=611+x
704-611=x
x=93
1/2 x 9/9 = 9/18
4/9 x 2/2 = 8/18
9/18 + 8/18 = 17/18
17/18 is less than 1
so your answer is false
hope this helps
