Answer:
18 feet long.
Step-by-step explanation:
Let the bottom section be x feet long, then:
x/6 + x/2 + x = 180
Multiply through by 6:
x + 3x + 6x = 1080
10x = 1080
x = 108 feet,
So the top section = 108/6
= 18 feet long.
Answer locate 3,6 with the slope of -1/4
Step-by-step explanation:
right
Answer:
Step-by-step explanation:
a.
y=0.75x
y-y1=(y2-y1)/(x2-x1)×(x-x1)
y-3=(6-3)/(8-4) (x-4)
y-3=3/4(x-4)
y-3=3/4 x-3
y=3/4 x-3+3
y=3/4 x
if y=f(x)
f(x)=0.75x
c.
f(12)=0.75×12=9$
Zero, because the angles don't add to 180
