An employment agency specializing in temporary construction help pays heavy equipment operators

Mathematics

bogdanovich [222]3 years ago

The answer is:
 Number of heavy equipment operators = 22
 Number of general laborers = 11
 The question can be solved by proposing a system of equations, where:
 Ep= number of heavy equipment operators.
 Tg= number of general labored.
 We have two equations, the first is the cost of hiring heavy equipment operators and general workers.
 
 135Ep+89Tg=3949.
 
 
  The second is the number of operators of heavy equipment and general workers that will be contracted. The total is 33.

 Ep+Tg=33.

 Solving the system of equations we have the answer is:

 Ep=22.
 Tg=11.

Answer:
Number of heavy equipment operators hired were 22
Number of general laborers hired were 11

Explanation:
Assume that number of heavy equipment operators hired is x and that number of general laborers is y.

We are given that:
1- Total number of hired people is 33. This means that:
x + y = 33
This can be rewritten as:
x = 33 - y ...........> equation I
2- heavy equipment operators are paid $135, general laborers are paid $89 and that the total payment was $3949. This means that:
135x + 89y = 3949 ............> equation II

Substitute with equation I in equation II and solve for y as follows:
135x + 89y = 3949
135(33-y) + 89y = 3949
4455 - 135y + 89y = 3949
506 = 46y
y = 506 / 46
y = 11

Substitute with y in equation I to get the value of x as follows:
x = 33 - y
x = 33 - 11
x = 22

Hope this helps :)

A rectangle with vertices A(6, 0), K(0,0), L(0,9), and M(6, 9) is rotated around the x-axis. To the nearest tenth of a cubic uni
koban [17]

Answer:

1526.0 cubic units

Step-by-step explanation:

Rotating rectangle AKLM you will get cylinder with height KA and base radius KL.  From the given data

KA=\sqrt{(6-0)^2+(0-0)^2}=6,\\ \\KL=\sqrt{(0-0)^2+(9-0)^2}=9.

The volume of the cylinder is

V_{cylinder}=\pi r^2\cdot H.

Then

V_{cylinder}=\pi \cdot 9^2\cdot 6=486\pi \approx 1526.0\ un^3.

If the United States government lowers the income taxes on the wealthiest Americans, while decreasing welfare payments to the po
Reika [66]

Answer:

True

Step-by-step explanation:

The State gets money out of charging taxes. If they lower taxes they will have less budget, so they will need to cut on the budget. In this case, if they will lower taxes on the welthiest, then they will have more resources, and be richer.On the other hand, the poorest will be poorer since the state will spend less on them, in conclusion as wealthy people will get richer, and poor people poorer, equality will reduce, since the difference between the tails on the  distribution will increase.

On the other side, a financial process is said to be tax efficient if it is taxed at a lower rate than an alternative financial process that achieves the same end, so in this case, tax efficiency will increase
