Answer:
m = -1
Step-by-step explanation:
Find the slope of this line.
x+y=5
y= (-1)x+5
Slope (m) = -1 <-- from y = mx+b
A line parallel to the line will have the slope -1.

Answer:
Part a) 
Part b) 132:89 vs 132 to 89
Part c) 
Part d) 66:7 vs 66 to 7
Step-by-step explanation:
Let
x ----> the number of boys
y ----> the number girls
z ----> the number of adults
we have
x=132, y=89, z=14
Part a) Write the ratio of the number of boys to the number of girls.
To find the ratio of the number of boys to the number of girls, divide the number of boys by the number of girls
so

substitute

Part b) Write the same ratio using another form (A: B vs. A to B)
we have

The other form is
132:89 vs 132 to 89
Part c) Write the ratio of the number of boys to the number of adults
To find the ratio of the number of boys to the number of adults, divide the number of boys by the number of adults
so

substitute

Simplify

Part d) Write the same ratio using another form
The other form is
66:7 vs 66 to 7
Answer:
670.21ft^3
Step-by-step explanation:
Volume of a cylinder=pi*r^2*h
Radius=8/2=4
Height=12
Volume=603.19
Volume of a cone=pi*r^2*(h/3)
radius=8/2=4
Hight=16-12=4
Volume=67.02
603.19+67.02=670.21ft^3
