The formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D
<h3>Equation</h3>
- Number of tires needed by each car = 4
- Number of spare tires needed by each car = 1
Total tires needed by each car = 4 + 1
= 5
- Number of cars produced per day = c
Total number of tires, t needed for c cars.
Number of tires needed, t = Total tires needed by each car × Number of cars produced per day
t = 5 × c
t = 5c
For instance,
if 5 cars are produced per day
Number of tires needed, t = Total tires needed by each car × Number of cars produced per day
t = 5c
= 5 × 5
t = 25 tires
Therefore, the formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D

The general form: x^2 + y^2 + Dx + Ey + F = 0, where D, E, F, are constants. If the equation of the circle is in the standard form, we can easily identify the center of the circle, (h, k,) and the radius, r. Note: The radius, r, is always positive.
Answer:
375 kilometers
Step-by-step explanation:
1cm = 75kilometers(150÷2= 75)
2cm = 150kilometers
75×5= 375kilometers
