Answer:
First table
Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y


Where k=Proportionality constant

K remain constant when x and y are in direct proportion
From first table




When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define

It is not direct proportion because k does not remain constant.
From third table


It is not direct proportion because k does not remain constant.
Answer:
B
Step-by-step explanation:
Answer:
C=29
Step-by-step explanation:
a^2 + b^2 = c^2
21^2 + 20^2 = c^2
441 + 400 = c^2
841 = c^2
\sqrt(841) = \squrt(c^2)
29 = c
So 5/8 of $24
5/8 * 24
15
Joshua spent $15.
Hope this helps :)
