Step-by-step explanation:
Please consider the complete question:
Micah is preparing for a piano recital. He practices for 50 minutes on Monday and 90 minutes on Wednesday. By how much did she increase the time she practiced each day?
We will use percent change formula to solve our given problem.
Upon substituting our given values, we will get:
Therefore, Micah had increased the time by 80%.
Step-by-step explanation:
Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 15 gallons of fuel, the airplane weighs 2187 pounds. When carrying 35 gallons of fuel, it weighs 2303 pounds. How much does the airplane weigh if it is carrying 50 gallons of fuel?
----
You have two points relating fuel and weight.
(15,2187) and (35,2303)
------------
slope = (2303-2187)/(35-15) = 5.8
----
intercept = ?
2187 = 5.8*15 + b
b = 2100
-------
Equation:
f(x) = 5.8x + 2100
---
f(50) = 2390 lbs.
