Hey there!
To start, first set up a proportion where x is the cost to make 27 copies:
27/x=150/4.50
Now, solve for x by cross multiplying which should look like this:
27*4.50=x*150
Now simplify and solve for x:
121.5=150x
x=0.81
Therefore, it costs $0.81 to make 27 copies.
Hope this helps!

Answer:
$124200
Step-by-step explanation:
Find the total hours worked by each employee: 8 * 5 = 40
$30 an hour people: 98 -11 = 87
Amount of money $30 an hour people each make: 30 * 40 = 1200
Amount of money $45 an hour people each make: 45 * 40 = 1800
$30 in total: 1200 * 87 = 104400
$40 in total: 1800 * 11 = 19800
All in total: 104400 + 19800 = 124200
Well,
If the slope of the lines are the same, then the lines are parralel.
We need to manipulate 2y - 10x = 4 into y = mx + b form.
Add 10x to both sides
2y = 10x + 4
Divide both sides by 2
y = 5x + 2
Do the same thing with the other equation.
Add 2 to both sides
y = 5x + 2
y = 5x + 2
It appears that, not only are they parallel, but they lie on exactly the same line! If this was a System of Simultaneous Linear Equations, then there would be an infinite number of solutions!<span />
Answer:
8 gallons
Step-by-step explanation:
Each rectangular face of the monument has an area of ...
A = bh = (9 ft)(39 ft) = 351 ft^2
The triangular face on top of that rectangle has an area of ...
A = (1/2)bh = (1/2)(9 ft)(10 ft) = 45 ft^2
So, one side of the monument has an area of ...
one side = (351 ft^2) +(45 ft^2) = 396 ft^2
The total area of all four identical sides is ...
surface area = (4)(396 ft^2) = 1584 ft^2
__
Each gallon covers 199 ft^2, to the number gallons required is ...
(1584 ft^2)/(199 ft^2/gal) ≈ 7.96 gal
Since only whole gallons can be purchased, 8 gallons of paint must be bought.
