Thank you for posting your question here. Please see below answers for the problem above:

a. to find the circumference of the tire you need to multiply 3.14 by 2.5:
 = 3.14 x 2.5
 = 7.85 to round of it will be 8

b. to get the number of times the tire have to rotate to travel 1 mile:

1 mile = 5,280 ft

8. There are 3 people who work full-time and are to work together on a project, but their total time on the project is to be equ
Mama L [17]

Answer:

1/6 of the third workers time

Step-by-step explanation:

one of the people is budgeted for 1 /2 of his time to the project and a second person for 1/3 of her time

Let x be the third workers time

Let the completed job time = 1

Time taken for 3 workers to complete the job = 1

\frac{1}{2}+ \frac{1}{3} + x= 1

now we solve for x

LCD = 2*3 = 6

We multiply the whole equation by 6

\frac{1}{2}*6+ \frac{1}{3}*6 + x*6= *6

3 + 2 +6x = 6

5 + 6x = 6

subtract 5 on both sides

6x = 1

divide both sides by 6

x= \frac{1}{6}
