part c: find the distance from b to e and from p to e. show your work (4 points)

answer:

80 %  

step-by-step explanation:

let g₇= games won in 2007

in 2008

g₈ = g₇ + 20 % of g₇

    = g₇ + 0.20g₇

    = g₇(1 + 0.20)

    =1.20g₇

in 2009

g₉ = g₈ + 50 % of g₈

    = g₈ + 0.50g₈

    = g₈(1 + 0.50)

    = 1.50g₈     substitute the value of g₈

    = 1.50(1.20g₇)

    = 1.80g₇

    = g₇(1 + 0.80)

    = g₇ + 0.80g₇

in 2009, the team won 80 % more games than in 2007.

answer:

231.7   cm^2

step-by-step explanation:

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)

      = 42.7

add the rectangles area to the area of the two triangles

189 + 42.7

231.7   cm^2

answer:

the parker family drove 120 miles on the first day

step-by-step explanation:

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.
