B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers

Answer:

Answer Below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = 5280 ft/7.85 ft per rotation = 672 rotations.

What is the value of the variable in the equation, r-17=22 *


please help me with this for brainliest and a cupcake

Answers

Answer:

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7,  or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

Answer: x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

Answer: r = 39. Add 17 to both sides and you’re left with r on the left and 39 on the right.
