Both linear and proportional because as x increases y decreases at the same rate
using pythagorean theorem
a^2 + b^2 =c^2
a^2 +8^2 =14^2
a^2 +64 = 196
subtract 64 from each side
a^2 = 132
take the square root of each side
a^2 = sqrt (132)
a=11.48912529
a =11.5
Answer:
D
Step-by-step explanation:
3/5 = 0.6
75% = .75
0.8, 0.75, 0.6, 0.56
The measure of angle ABC is 100 because all you do is add the 60 to the 40 and get 100.
Using a proportional relationship, it is found that Carlos earns an allowance of $7.5 for each chore that he completes.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the constant is:
k = 75/10 = 97.5/13 = 112.5/15 = 7.5.
Hence Carlos earns an allowance of $7.5 for each chore that he completes.
