Since we are finding the unit rate of the cost per comic, we will need to divide $5 by 20 comics which you will get 0.25 cents and divide $7.50 by 30 comics which you will also get 0.25 cents.Therefore, the unit rate and constant of proportionality is 0.25 cents.
Answer:
The answer is option D.
Step-by-step explanation:
cos M = adjacent / hypotenuse
From the picture
b is the adjacent
x is the hypotenuse
so
cos M = b/x

Answer:
x ≈ 13.5
Step-by-step explanation:
Using the sine rule in the triangle, then
= ( cross- multiply )
x × sin27° = 11 × sin34° ( divide both sides by sin27° )
x = ≈ 13.5 ( to the nearest tenth )
