A bicycle wheel has a circumference of 62 inches. Find the diameter of the wheel. If necessary, round to the tenths place. A. 39

san4es73 [151]

Answer:

The answer to your question is diameter = 19.7 in

Step-by-step explanation:

Data

Circumference = 62 in

diameter = ?

Process

1.- Write the formula of Circumference, remember that circumference = perimeter.

Perimeter = 2πr

2.- Equal the equation to the value given

2πr = 62

-Solve it for r

r = 62/2(3.14)

-Result

r = 62/6.28

r = 9.87 in

3.- Find the diameter

diameter = 2r

diameter = 2(9.87)

diameter = 19.7 in

Graph the solution of the inequality: 3/7 (35x-14) ≤ 21x/2 + 3

hammer [34]

Hello there!

In order to graph the solution, we need to solve it first.

So let's start....

3/7(35x - 14) ≤ 21x/2 + 3

15x -6 ≤ 21x/2 + 3

15x - 21x/2 ≤ 3 + 6

9x/2 ≤ 9

x ≤ 9* 2/9

x ≤ 18/9

x ≤ 2

See the picture for the graph

Please let me know if you have questions about the answer.

Thanks!
