Solve for w and l by using the system of equations.
2l=-2w+228
l=w+42
Substitute w+42 for l in the first equation.
2(w+42)=-2w+228
2w+84=-2w+228
4w=144
w=36
Now substitute 36 for w in any equation to get l=78.
To graph the equations, first make them equal l.
l=-w+114 and l=w+42 are your equations. You ca plug in values for w to plot points on the graph.
The three is in the tenths place so the numerator is 3 and the denominater is 10 so the equivalent fraction would be 3/10
Answer:
9.) 6.5 ft
10.) 36 ft²
11.) 770 cm²
12.) 10,087 cm³
Step-by-step explanation:
9.) Find the height:
V = lwh
234 = 8(4.5)h
234 = 36h
/36 /36
6.5 = h
10.) Area of base:
B = lw
B = 8(4.5)
B = 36
11.) Area of the base:
B = lw
B = 35(22)
B = 770
12.) Volume of the pyramid:
V = Bh/3
V = 770(39.3)/3
V = 30,261/3
V = 10,087
