Answer:

Step-by-step explanation:

Lisa an experience shipping clerk can fill a certain order in 2 hours.

Jim a new clerk needs 3 hours to do the same job working.

For 1 hours Lisa can fill  1/2 a order.

For 1 hours Jim can fill  1/3 a order.

For 1 hours togethers  can fill 1/2+ 1/3=5/6 a order.

We have the following proportion:

1:\frac{5}{6}=x:1\\\\\frac{5}{6}x=1\\\\x=\frac{6}{5}

Together they will complete the order in 6/5 hours.

a circle with radius 3 has a sector with a central angle of 17/9 pi radians. what is the area of the sector?
r-ruslan [8.4K]

Answer:

The area of the sector is 26.69

Step-by-step explanation:

First of all we need to calculate the area

To solve this problem we need to use the area formula of a circle:

a = area

r = radius =   3

π = 3.14

a = π * r²

we replace with the known values

a =  3.14 *  (3)²

a =  3.14 * 9

a = 28.26

The area of the circle is 28.26

A complete circle has 2pi radians

We divide 17/9 pi by 2pi and obtain the fraction of the total circle

(17pi/9) / 2pi = 17/18

we multiply this fraction with the area of the circle and obtain the area of the sector

28.26  * 17/18 = 12.43cm

The area of the sector is 26.69
