The proportional relationship involving c and b is c ∝ b. The solution to c is c = kb (where k is constant)
Variation is a mathematical notion that relates to variability. Variation is defined to be any change in one quantity as a result of a change in another. Variation questions feature relatively basic connections or formulae in which one variable equals one term.
From the given question
- if c represents the number of calories, and
- b represents the number of brownies.
A direct variation is a type of variation in which an increase in one term increases the other term as well, and, vice versa.
Let assume the proportional relationship follows a direct variation.
Then,
c ∝ b
The solution to c is:
c = kb
(where k is the constant)

Using proportions, it is found that $15.00 in quarters weigh 29.4 grams less today than before 1965.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, a quarter is worth $0.25, hence $15.00 in quarters is composed by 60 quarters, as:
Before 1965, the total weight was of:
60 x 6.25 = 375 grams.
After that, the total weight is of:
60 x 5.76 = 345.6 grams.
Hence the difference is:
375 - 345.6 = 29.4.
$15.00 in quarters weigh 29.4 grams less today than before 1965.

Answer:
a. True, because they are corresponding angles.
b. False, because angles 1 and 2 are supplementary, meaning that they add up to 180 degrees, but 125 + 65 = 190 degrees.
c. True, because they are corresponding angles.
d. True, becuase they are two angles that add up to 180 degrees.
e. True, because they are both interior angles on opposite sides of the transversal.

Answer:
3 hours + 5hours = 8 hours ÷ 2 =
4 hours is your answer.
Step-by-step explanation:
If you have 2 people working and need to know how long it would take them to finish a job. Working together on the same job, you add each of their total hours to do the job alone,, 5 + 3 = 8, then divide the 8 by 2 people
equals 4 hours for 2 people on 1 job.
