Answer:

33 gallons of water to begin with.
Step-by-step explanation:
So we essentially are given two coordinates: (6,87) and (21,222). To find an equation, we simply need to find the slope and y-intercept. We know it's a linear equation because it's a steady stream, meaning a constant slope.
The slope is:

So, the rate at which the stream flows is 9 gallons per minute.
Now, let's find the initial amount of water. To do this, we can use point-slope form. Pick either of the two points. I'm going to use (6,87).

So, there were 33 gallons of water in the tank to begin with.
Answer: 50 + 2x
Step-by-step explanation: It's pretty basic math, you have your flat fee ($50) and then you add your variable 2x. 2 is multiplied by x so you can figure out the amount that it costs to ride the rides.
Step-by-step explanation:
Given
Area of rectangle (A) = 243.9 m²
Length (L) = 15 m
first calculating the breadth (b)
We know
L * b = A
15 * b = 243.9
b = 243.9/ 15
b = 16.26 m
Now
Perimeter (p)
= 2 ( L + b)
= 2 ( 15 + 16.29)
= 62.58 m
