Answer:
304m^2
Step-by-step explanation:
First find the surface area of the base by multiplying the length by the width.
(12m) (8m)= 96m^2
Second, find the surface area of the front and back triangles using the formula <em>1/2 (base) (height)</em>. Use the length for the base.
1/2 (12m) (10m)= 60m^2
Next, find the surface area of the side triangles using the formula <em>1/2 (base) (height). </em>Use the width as the base.
1/2 (8m) (11m)= 44m^2
Last, add the surface area of each section. Make sure you add the area of each face.(we only solved for 1 of the front/ back triangles and 1 of the side triangles) To make it easier to understand I wrote out an equation to show how I added the surface areas.
base=a, front/ back triangles= b, side triangles=c
SA= a + 2b +2c or SA= a +b +b +c +c
Using one of the equations above solve for the total surface area.
SA= (96m^2) + (60m^2) +(60m^2) +(44m^2) +(44m^2)
or
SA= (96m^2) + 2(60m^2) +2(44m^2)
SA= (96m^2) +(120m^2) +(88m^2)
SA= 304m^2
Answer:
10 inches
Step-by-step explanation:
They're 36 degrees, so corresponding angles are the same, so the middle line is parallel to the bottom line of the triangle.
But the middle line bisects one of the waist lines of the triangle, so this is the middle line, which is equal to half the length of the bottom line
Answer:

a) y = -x + 2
b) (2,1)
Step-by-step explanation:
Explained in the attachment.
Answer: When they work 10 hours each, they both make $300.
kelli y = 20x + 100
karl y = 25x + 50
substitution:
y = 20x + 100
25x + 50 = 20x + 100
-20x -50 -20x -50
--------------------------------
5x = <span>50
</span>5 5
x = 10
(Then plug into any equation)
y = 25x + 50
y = 25(10) + 50
y = 300
When they work 10 hours each, they both make $300.
