Answer:
Area of triangles 1 = 18 ft²
Area of triangles 2 = 16 in²
Area of triangles 3 = 90 yd²
Step-by-step explanation:
Given:
1] Height of triangle = 4 ft
Base of triangle = 9 ft
2] Height of triangle = 4 in
Base of triangle = 8 in
3] Height of triangle = 12 yd
Base of triangle = 15 yd
Find:
Area of triangles
Computation:
Area of triangles = (1/2)(Base)(Height)
Area of triangles 1 = (1/2)(4)(9)
Area of triangles 1 = 18 ft²
Area of triangles 2 = (1/2)(4)(8)
Area of triangles 2 = 16 in²
Area of triangles 3 = (1/2)(12)(15)
Area of triangles 3 = 90 yd²
Number One:
One lawn mowed = 15 dollars earned
Two lawns mowed = 30 dollars earned
Three lawns mowed = 45 dollars earned
Four lawns mowed = 60 dollars earned
And so on, so yes, it is proportional.
Number Two:
Week one: 120 dollars
Week Two: 125 dollars
Week Three: 130 dollars
Week Four: 135 dollars
And so on, so yes, I believe it's proportional.
Lucas read 26 pages per hour so it's proportional. Brianna didn't have a proportional relationship. It went: 28, 30 and then 29 pages per hour for her.

Answer:
the period is the to top points of the highest points on top of the crests
Yes 45/45 = 1 +10 = 11
13 > 11
