30% is equivalent to 0.3. So 15 x 0.3 = 4.5. Therefore, 30% of $15 is $4.50.
65.95 + 32.63 = 98.58
270 - 98.58 = 171.42
171.42 divided by 14.85 = 11.54

Part A: What does the x-intercept of the function for car 1 represent? (2 points)
For this case, the intersection with the x axis means that car 1 has reached its destination. He traveled 70 km in 70 minutes.
Part B: What does the y-intercept of the function for car 2 represent? (2 points)
For this case, the intersection with the Y axis represents that car 2 must travel 70 km to reach its destination and that it has not yet started its journey.
Part C: What is the domain of the functions for car 1 and car 2? (2 points)
car1:
The domain of the function for this car are all x that range from 0 to 70. Mathematically it can be written as [0, 70].
car 2:
The domain of the function for this car are all x that go from 0 to more infinity. Mathematically it can be written as [0, inf)
Part D: What is the average rate of change from x = 30 to x = 40 for the function representing the motion for car 2? What is the value of this average rate of change?
For the domain between x = 30 and x = 40 the rate of change of the function of the car 2 is 34.69144.
This means that car 2 travels 34.69144 km approximately in 10 minutes. As the slope is negative, then the car is getting closer to its destination.
Answer:
3/2
Step-by-step explanation:
You can divide both 12 and 8 by four. Dividing 12 by four gives you 3 and dividing 8 by 4 gives you 2. This makes the simplified fraction 3/2

Answer:
$3562.50
Step-by-step explanation:
If the cost ratio is ...
labor : parts = 3/5 : 1 = 3 : 5
then the ratio of labor to the whole cost is ...
labor : total = 3 : (3+5) = 3 : 8
The amount saved by not paying for labor is ...
(3/8) × $9500 = $3562.50 . . . labor charge
