Assume that your present job pays a monthly gross salary of $1,560. You are offered a new position that pays $8.60 per hour with
motikmotik

Answer:

There are 4 weeks in a month and 40 working hours in a week

Since the $8.60 per hour, the gross monthly salary for your new position = 8.60*40*4 = $1,376

Your gross monthly salary at present job = $1,560

So the additional amount that you need to earn at your new position = 1,560-1,376 = $184

The hourly wage for addtional hours more than 40 hours at the new position = 1 1/2 * 8.60 = 1.5*8.60 = $12.90

So, number of hours that you need to work extra = 184/12.90 = 14.26 hours per month

So, number of hours that you need to work extra per week = 14.26/4 =  3.566 hours or 3.57 hours (Rounded to 2 decimals)

To which graph does the point (−1, 3) belong? y ≥ 2x + 6 y ≥ 3x − 1 y ≥ −x + 3 y ≥ −2x + 5
Anna35 [415]
Well first find the slope of the point
y=mx+b  y=-1x+3
slope = -1
then put the problem in point slope form y - y1 = m (x-x1)
y + 3 = -1 (x+1) then solve for y=mx+b again
so y> 2x + 6 is the answer

Find thr valuse of x, rounded to the nearest tenth.<br><br>3.8<br>4<br>2.7<br>2.9​
irina1246 [14]

Answer: 4  (OPTION 2)

Step-by-step explanation:

1. To solve this problem you must apply the  Intersecting secants  theorem, as you can see below:

(A+B)B=(C+D)D

Where:

(A+B)=6

B=x\\(C+D)=8\\D=2

2. Then you must susbstitute values and solve for x, as following:

6x=24\\x=24/6\\x=4

Therefore the answer is the second option.
