LisaLisa, an experienced shipping clerk, can fill a certain order in 1010 hours. BillBill, a new clerk, needs 1111 hours to do the same job. Working together, how long will it take them to fill the order?

Step-by-step explanation:

GIVEN: Lisa, an experienced shipping clerk, can fill a certain order in hours.Bill, a new clerk, needs hours to do the same job.

TO FIND: Working together, how long will it take them to fill the order.

SOLUTION:

Total hours taken by Lisa hours

Total hours taken by Bill hours

Let the total time taken when working together be hours

Total time taken by Lisa and Bill when working together

hours

Hence Lisa and Bill will take hours to fill the order when working together.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
