Answer:
The number of gallons of gas Karl used is 15 gallons.
Option (C) is correct.
Step-by-step explanation:
As given
Karl drove 617.3 miles.
For each gallon of gas, the car can travel 41 miles.
i.e
1 gallons = 41 miles
![1\ miles = \frac{1}{41}\ gallons](https://tex.z-dn.net/?f=1%5C%20miles%20%3D%20%5Cfrac%7B1%7D%7B41%7D%5C%20gallons)
Now find out for the 617.3 miles.
Thus
![617.3\ miles = \frac{617.3}{41}\ gallons](https://tex.z-dn.net/?f=617.3%5C%20miles%20%3D%20%5Cfrac%7B617.3%7D%7B41%7D%5C%20gallons)
![617.3\ miles = 15.1\ gallons](https://tex.z-dn.net/?f=617.3%5C%20miles%20%3D%2015.1%5C%20gallons)
![617.3\ miles = 15\ gallons\ (Approx)](https://tex.z-dn.net/?f=617.3%5C%20miles%20%3D%2015%5C%20gallons%5C%20%28Approx%29)
Therefore the number of gallons of gas Karl used is 15 gallons.
Option (C) is correct.
A)
Monday and Tuesday: 8*6=48
Thursday and Friday: 10*6=60
60-48=12
The answer is 12 more
B)
48+60=108

(a) <em>Slope and intercept
</em>
In the equation y = 2x +8, the coefficient of x is the slope and the constant is the y-intercept.
Thus,
slope = 2; y-intercept = 8
===============
(b) <em>Rate of change and initial amount
</em>
The rate of change is the slope. The units of y are baskets of apples and the units of x are hours. So,
rate of change = 2 baskets of apples per hour
The initial amount when x = o.
When x = 0, y = 8. so
Initial amount = 8 baskets of apples
===============
(c) <em>Graph
</em>
Your graph should look something like the one below.

Answer:
6.5 ft wide by 8 ft long
Step-by-step explanation:
We can let x represent the width of the rectangle. Then the length is ...
L = 2x -5
and the area is ...
A = LW = (2x -5)(x) = 52
2x² -5x -52 = 0 . . . . . put in standard form
(2x -13)(x +4) = 0 . . . . factor
x = 6.5, -4 . . . . . . . . . . values that make the factors zero
The length is then ...
L = A/W = 52/6.5 = 8
or
L = 2W -5 = 2(6.5) -5 = 13 -5 = 8
The rectangle is 6.5 feet wide and 8 feet long.
