A tire has a radius of 7.5 inches. How many inches will the tire travel after one rotation?
1 answer:
Answer:
80
Step-by-step explanation:
You need to calculate the circumference of this wheel to determine how far it travels with each revolution.
First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.
You need to calculate the circumference of this wheel to determine how far it travels with each revolution.
First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.
The magic number here is pi, which is roughly 3.14159265. The digits to the right of the decimal point continue infinitely.
Dividing a circle’s circumference by pi will give you a circle’s diameter.
Multiplying a circle’s diameter by pi will give you a circle’s circumference.

Answer:
The explicit formula for a given geometric sequence is of the form
Step-by-step explanation:
Given sequence is
Let
To find the common ratio r:
Therefore r=-3
Therefore r=-3
Therefore common ratio is -3
Therefore given sequence is geometric sequence.
The explicit formula for a geometric sequence is , where common ratio is r.
From given sequence we are having r=-3
Therefore the explicit formula for a given geometric sequence is of the form
Answer:
180 cars
Step-by-step explanation:
Like you can see in the picture, I like to set up a proportion, so 81 over X and 45 over 100. Then, you can cross multiply, so 81 x 100 = 8100 and then divide, 8100 ÷ 45 = 180, your answer!
