the diagram below models the layout at a camival where g, rp. c. band e are various locations on the grounds. grpc is a parallelogram.
part a: identify a pair of similar triangles (2 points)
part b: explain how you know the triangles from part a are similar (4 points)
part c: find the distance from b to e and from p to e. show your work (4 points)
let g₇= games won in 2007
g₈ = g₇ + 20 % of g₇
= g₇ + 0.20g₇
= g₇(1 + 0.20)
g₉ = g₈ + 50 % of g₈
= g₈ + 0.50g₈
= g₈(1 + 0.50)
= 1.50g₈ substitute the value of g₈
= g₇(1 + 0.80)
= g₇ + 0.80g₇
in 2009, the team won 80 % more games than in 2007.
we can find the area by adding the area of the rectangle to the area of the 2 triangles.
the rectangle is
7+7+7 by 9
21 by 9
a = length * width
a = 21*9
a = 189
the triangles are identical so we find the area of one of them and multiply by 2
the base is 7 and the height is 6.1
a = 1/2 b*h
but since we have 2 of them
2a = 2*1/2 b*h
2a = b*h
2a = (7* 6.1)
add the rectangles area to the area of the two triangles
189 + 42.7
the parker family drove 120 miles on the first day
180m divided by 1.5 is 120m. you can double check this by multiplying 1.5 time 120 , and the answer you would get would be 180.
