Answer:

9.3

Step-by-step explanation:

last week she worked 45.6 hours. since 40 hours is the limit for normal working hours, she worked 45.6-40 = 5.6 hours overtime.

this week she worked 9.7+8.3+8+9.1+8.6 hours = 43.7 hours.

she worked therefore 43.7-40 = 3.7 hours overtime.

so, in total of the two weeks, she worked 5.6+3.7 = 9.3 hours overtime.

slamgirl [31]

Answer:

there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

Grace has a 15 inch diameter bicycle tire. How many revolutions will it make traveling 500 feet?

Brums [2.3K]

Answer:

Revolution = 127.24 revolutions

Step-by-step explanation:

Circumference of the tire = πD

Where D = 15 inch

So,

C = 15π = 47.1 inch

In feets:

47.1 inch = 3.93 feet.

So, one revolution = 3.93 feet

Travelling 500 feet will make the following revolutions:

Revolution = 500 feet/3.93 feet

Revolution = 127.24 revolutions
