Answer:
-7
Step-by-step explanation:
202 ft^2
The lateral area is the area of all the sides except the base. So you find the area of the triangles (16), then the left rectangle (80), then the right rectangle (90). Finally you add them together.
16+16+80+90=202
Answer:
walk is 24 people
bus is 44 people
Step-by-step explanation:
100% is 80
30% walk
15% bike
55% bus
work out 30%
so 50% is 40
25% is 20 (dived by 2)
5% is 4 (divide 50 by 10)
30% is 24
for bus do 50% is 40
5% is 4
55% is 44 (add)

Answer:
ED: 6.5 cm BE = 14.4 cm
Step-by-step explanation:
Add 20 and 5 to get side AC.
25/20 gives us the scale factor to go from 25 triangle ABE to triangle ACD.
Multiply 26 by the SF to get AD.
Subtract length of AD by AE to get ED. You should get 6.5 cm (don't forget units!!!!)
To go from triangle ACD to triangle ABE, we can do 20/25 to get the scale factor.
Using that number, multiply it with 18 to get BE.
The answer should be 14.4 cm.
This is possible because the two triangles ACD and ABE are similar via the angle angle angle similarity theorem depicted in my screenshot.
