Answer:
c. 56.2 mph
Step-by-step explanation:
In most cars, the speedometer reading is proportional to tire rotation speed, so a larger diameter tire will go farther for the same number of rotations. That is, the distance traveled in a certain length of time is proportional to the tire circumference, which is proportional to the tire diameter.
The car with new tires will actually be going at the speed of ...
(26 in)/(24.5 in) × (53 mi/h) ≈ 56.245 mi/h ≈ 56.2 mph
Answer is C. 52 hours. because you divide the amount her earned with the $24 that he gets each hour
Using the fundamental counting theorem, it is found that 17,576,000 different license plates can be manufactured.
Fundamental counting theorem:
States that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem:
- Since repetition is allowed, for the 3 letters, there are 26 outcomes, hence .
- For the 3 numbers, there are 10 outcomes, hence
Then:
17,576,000 different license plates can be manufactured.
