Y = 3x + 48 where x is your number of years. I got 48 by multiplying 4 and 12 since there are 12 inches in a foot. (:
The table of the tolls for Henderson is the direct variation since the cost is proportional to the miles traveled.
Answer:
84 cookies
Step-by-step explanation:
First, find the amount she bakes per minute. It is given that Marissa bakes 30 cookies every 15 minutes, or:
30 cookies/15 minutes = 2 cookies/minute.
Marissa bakes 2 cookies per minute. Multiply 2 with 42 minutes to find the total cookies baked in 42 minutes:
42 x 2 = 84
84 cookies is your answer.

Answer:
20 km
Step-by-step explanation:
We will imagine a triangle. The hypotenuse of the triangle is the distance between you and the plane. 16 kilometres is the aerial space between you two, in other words its the base of the triangle. 12 km is the length of the third leg of the triangle. We will apply the pythagorean theorem to find the length of the hypotenuse and the distance between you and the plane.
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root of 400 is c which equals 20 km.
