Answer:
$35 per hour
Step-by-step explanation:
The total charge is the sum of costs of parts and labor. If h is the cost of a labor hour, then we have ...
188.75 = 75 + 3.25h
113.75 = 3.25h . . . . . . . . subtract 75
113.75/3.25 = h = 35 . . . divide by the coefficient of h
The cost of labor, per hour, is $35.
hello!
so area of a square is calculated by this equation
s^2 = a
which means if you multiply two sides together you get the area
what you want to do now is to find a side of the square
plug in the 900 square meters
s^2 = 900
square root both sides to isoate the variable
s = 30 meters
this means that one side is 30 meters
since it is a SQUARE all four sides are equal
just multiply 30 by 4 and that will get the amount of fencing you'll need
30*4 = 1200 meters
you will need 1200 meters of fencing
WAIT
there is a possibility that one side of the house has already enclosed one side of the fence
so if that's the deal then
30*3 = 900meters
IF ONE SIDE OF THE HOUSE IS ALREADY ENLCOSING ONCE SIDE THEN YOU WILL NEED 900 meters of fencing.
Graphing, Substitution Method and Elimination Method
PEMDAS. Parenthesis comes first. 3+2 = 5 which is then multiplied to 6/2 which is 3 so 3 x 5 is 15.
