Suppose you can work a total of no more than 38 hours each week at your two jobs. Housecleaning pays $7 per hour and your retail

Answer:

<u>The system of inequalities is:</u>

<u>7x + 8y ≥ 280</u>

<u>x + y ≤ 38</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Amount of weekly hours you can work, no more than 38 hours (≤ 38)

Rate at housecleaning per hour = US$ 7

Rate at retail job per hour = US$ 8

Salary per week, at least US$ 280 (≥ 280)

2. Complete the system of linear inequalities to model this situation.

x = Number of hours per week worked at housecleaning job

y = Number of hours per week worked at retail job

Now, we have:

7x + 8y ≥ 280 (Total of salary of the two jobs should be at least US$ 280), where 7x is the salary received from housecleaning job and 8y is the salary received from retail job

x + y ≤ 38 (You can't work more than 38 hours per week)

Alexxandr [17]

Answer: I think

Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)

If the smallest angle of rotation for a regular polygon is 18°, how many sides does polygon have?
lora16 [44]

Answer:

20 sides.

Step-by-step explanation:

The external angles of a polygon sum to 360 degrees.

So it's 360/18 = 20.

A rocket is launched from the top of a 55-foot cliff with an initial velocity of 138 ft/s.
melisa1 [442]

For this case we have that the equation that describes the height is:

h = -16t ^ 2 + vt + c

Where,

v: initial speed

c: initial height

Substituting values we have:

h = -16t ^ 2 + 138t + 55

Then, to find the time, we use the quadratic formula:

t =\frac{-b +/-\sqrt{b^2 - 4ac} }{2a}

Substituting values we have:

t =\frac{-138 +/-\sqrt{138^2 - 4(-16)(55)} }{2(-16)}

Rewriting:

t =\frac{-138 +/-\sqrt{19044 + 3520} }{-32}

t =\frac{-138 +/-\sqrt{22564}}{-32}

t =\frac{-138 +/-150.21}{-32}

We discard the negative root because we want to find the time.

We have then:

t =\frac{-138 -150.21}{-32}

t =\frac{-288.21}{-32}   \\t=9

Answer:

D. 0 = -16t^2 + 138t + 55; 9 s
