A family is purchasing concrete in order to create a foundation for a rectangular outdoor
Murrr4er [49]

Answer:

42.5 Cubic Yards

Step-by-step explanation:

To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.

Find the value of x​
seraphim [82]

Answer:

x = 66

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360 degrees

103+133+58+x = 360

Combine like terms

294+x = 360

Subtract 294 from each side

294+x-294 = 360-294

x = 66
