1) You need to graph this one in order to find out the ordered pair. Your y-intercept is positive 4, so that's where you should start. From there, your slope is negative 11 so you'll go down 11 times and move one over. The line should go across the ordered pair of (1, -7). So, your answer is C (1, -7).

2) c = 65h
In this equation, c represents the total cost. 65 is the price charged per hour to fix a leak. So, if I were to say it took a plumber two hours to fix a leak then my equation would be:

c = 65(2)
c = 130

Thus, the cost is $130.

3) The problem says solve for x, however, I don't see the input of x anywhere.

4) c = b - bx

c = b(1-x)

c/b = 1 - x

c/b - 1 = -x

-c/b + 1 = x

This equation is read as: negative c over b plus 1 equals x

if the area of a square is 144 feet and the perimeter of the triangle is 28 feet, what is the perimeter of the room's floor?
FinnZ [79.3K]

Answer:

52+12\pi

Step-by-step explanation:

The diagram for the question is attached below

perimeter of the triangle is 28 feet

area of a square is 144 feet

Area of the square is side^2

side ^2= 144

take square root on both sides

side = 12

side of the square = 12

side is the diameter of the semicircle

Diameter = 12 , so radius = 12 divide 2 = 6

circumference of semicircle = 2\pi r=2\pi (6)=12\pi

one side of the rectangle is calculated in the perimeter of triangle and other side is calculated using circumference

perimeter of other two side = 2(12)= 24

Total perimeter = 28+24+12\pi =52+12\pi
