How much work is done in an hour by each:
s = 1/6 of the yard in one hourb = 1/10 of the yard in an hour
working together they can do:
1/6 + 1/10 in an hour; or 16/60; we can invert this number to determine how long it takes to finish the yard
60/16 hours

=3 hours and 45 minutes

Answer:

In 3 hour 45 minutes Both working together do all of yard work.

Step-by-step explanation:

Time taken by Steve to do yard work = 6 hours

Work Done by Steve in a hour = \frac{1}{6}

Time taken by Bill to do yard work = 10 hours

Work Done by Steve in a hour = \frac{1}{10}

Work done by both in a hour = \frac{1}{6}+\frac{1}{10}=\frac{5+3}{30}=\frac{8}{30}=\frac{4}{15}

Time taken by by both working together = \frac{1}{\frac{4}{15}}=\frac{15}{4}=3.75=3\,hour\,45\,minutes

Therefore, In 3 hour 45 minutes Both working together do all of yard work.

1. In the figure, m DE=124, and M BC=36. The diagram is not drawn to scale. What is m A? A) 44* B) 62* C) 80* D) 88* please help
Anuta_ua [19.1K]

The relation between arc length and exterior angle is given in the figure.

Now we are given far arc length as DE =124

We are given near arc length as BC = 36

So plugging in the formula to find measure of angle A:

angle A=\frac{far arc-near arc}{2}

angle A=\frac{124-36}{2}

angle A=\frac{88}{2}

Angle A = 44 degrees

Answer : A) 44 degree
