You can conclude that AE = DE because the triangles are about equal
The correct answer is .25
Set up a proportion: 25/100 = 50/n where n = # of teens surveyed
Simplify fraction: 1/4 = 50/n
Cross multiply: n = 200
So 200 teens were surveyed.
.059, you move the decimal point two times to the left and the other way around when you want to convert into a percent
Answer:
<em>1, 4.5</em>
Step-by-step explanation:
for midpoint
x₁ = -2, y₁ = 0
x₂ = 4, y₂ = 9
for midpoint
(x₁+x₂)/2 , (y₁+y₂)/2
(-2+4)/2 , (0+9)/2
2/2 , 9/2
1, 4.5
