At the beginning of summer, Mark has $200 in savings and Ryan has $350 in savings the brothers have mowing jobs set up for the s
Vanyuwa [196]

9514 1404 393

Answer:

  • Mark: s = 200 +20j
  • Ryan: s = 350 +15j
  • 30 jobs

Step-by-step explanation:

The amount in savings (s) will be the initial amount plus the product of the pay per job and the number of jobs (j).

<u>Mark</u>

He initially has $200, and is paid $20 per job. His savings will be ...

  s = 200 +20j

<u>Ryan</u>

He initially has $350, and is paid $15 per job. His savings will be ...

  s = 350 +15j

<u>Same Savings</u>

The savings will be the same when the difference between the amounts is zero:

  s - s = 0

  (200 +20j) -(350 +15j) = 0 . . . . . substitute the expressions for s

  -150 +5j = 0 . . . . . collect terms

  -30 +j = 0 . . . . . . . divide by 5

  j = 30 . . . . . . add 30

The brothers will have the same amount in savings after they each work 30 jobs.

In the figure, mZRPZ = 95 and TU ||RQ|| VW. Find the measure of angle YSV.
madreJ [45]

Answer:

m\angle YSV=85^o

Step-by-step explanation:

The complete question in the attached figure  

step 1

Find the measure of angle QPZ

we kno that

m\angle RPZ+m\angle QPZ=180^o ---> by supplementary angles (form a linear pair)

we have

m\angle RPZ=95^o ---> given value

substitute

95^o+m\angle QPZ=180^o

m\angle QPZ=180^o-95^o

m\angle QPZ=85^o

step 2

Find the measure of angle YSV

we know that

When two lines are crossed by another line, <em><u>Alternate Exterior Angles</u></em> are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. If the two lines are parallel then  the alternate exterior angles are congruent.

In this problem

The transversal is the line XY

The two parallel  lines are RQ and VW

therefore

m\angle YSV=m\angle QPZ ---> by alternate exterior angle

we have

m\angle QPZ=85^o

therefore

m\angle YSV=85^o
