Answer:
C. It is just right.
Step-by-step explanation:
We want to compare the ratios ...
bags : liters = 15 : 2
and
bags : liters = 90 : 12
If we multiply the numbers of the first ratio by 6, we see they are identical to those in the second ratio:
(15)(6) : (2)(6) = 90 : 12
The ratio of bags to liters for Peggy's tea matches the ratio Kermit likes. He will think it is just right.
You have to use the formula: a^2 + b^2 = c^2
9^2 + 11^2 = c^2
9^2 = 81
11^2 = 121
81 + 121 = 202
Now you find the square root of 202
That would be 14.2126704
But you can round it to 14.21
