Jenica bowls three games and scores an average of 116 points per game. She scores 105 on her first game and 128 on her second game. What does she need to score on her third game to get a mean score of 116?

115 points on her third game.

Step-by-step explanation:

To find the answer add the first and second games together.

128 + 105 = 233 ÷ 2 = 116.5 (then divide by two because there is two games).

This is the average of two games. To find the average of THREE games try different numbers to see which number works.

233 + 110 = 343 ÷ 3 = 114.3

(so we have to try a higher number than 110).

233 + 112 = 345 ÷ 3 = 115 on average (still not enough).

233 + 115 = 348 ÷ 3 = 116. (we found the answer!)

233 + 115 = 348 ÷ 3 = 116

a

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
