Similar triangles have corresponding sides with proportional lengths.
AB/BC = DE/EF
5/9 = 7.5/EF
5(EF) = 9 * 7.5
5(EF) = 67.5
EF = 13.5

Answer:
5/22
Step-by-step explanation:
A bag has 6 blue marbles, 4 red marbles, and 2 green marbles. Wo marbles are randomly chosen without replacement.
Total number of marbles =
6 blue marbles + 4 red marbles + 2 green marbles
= 12 marbles
The probability of picking a blue marble = P(B) = 6/12
Therefore, the probablilty that both marbles picked are blue without replacement is
= 6/12 × 5/11
= 30/132
= 5/22
B + G = 5273
G = B + 231
B + B + 231 = 5273
2B + 231 = 5273
subtract 231 from both sides
2B = 5042
divide both sides by 2
B = 2521
G = 2521 + 231
G = 2752
There are 2752 girls and 2521 boys LETTER D
