the use of the plane varies directly with the square root
of the time the plane is used. If a lesson plus 16 minutes
of plane usage costs $90, what is the total amount
charged for a lesson having 36 minutes of plane usage?
The total amount charged for a lesson having 36 minutes of plane usage is $110.
Given that, a flight instructor charges $50 per lesson, plus an additional fee for the use of his plane.
The charge for the use of the plane varies directly with the square root of the time the plane is used.
x∝√y
x=k√y
Here, 90 = 50 + k√16
k = (90-50)/4
k = 40/ 4
k = 10
For 36 minutes, total charge
Total amount charged = 50 +10√36
Total amount charged = 50 + 10×6
Total amount charged = 50+60
= $110
Therefore, the total amount charged for a lesson having 36 minutes of plane usage is $110.

Answer:
s = 260 - g/2
Step-by-step explanation:
Given the following :
Maximum weight swing can hold = 500 pounds
Let suspect's weight = s
George's weight = g
To reach maximum weight :
Double weight of suspect + (George's weight - 20)
Hence, equation:
2s + (g - 20) = 500
2s + g - 20 = 500
2s + g = 500 + 20
2s + g = 520
2s = 520 - g
Divide through by 2
s = 260 - g/2
The question can be represented by the equation 2S + G - 20 = 500, where S is the suspect's weight and G is George's weight. To solve for the suspect's weight, we need to know George's weight.
The question asks for an equation to determine the weight of the suspect based on given conditions. We can express the condition as a mathematical equation. If we let S be the weight of the suspect and G be the weight of George, the information gives us the equation 2S + G - 20 = 500. To solve for the suspect's weight, we will need the weight of George. Without this, there are an infinite number of solutions for S. However, if we were given George's weight, we could subtract 20 from it, subtract that value from 500, and then divide by 2 to get the suspect's weight. As an example, if George weighed 220 pounds, the suspect would weigh (500 - (220 - 20)) / 2 = 150 pounds.
