Answer:
2880 ways
Step-by-step explanation:
There can be only one arrangement in which boys and girls can sit.
G-B-G-B-G-B-G-B-G
but position of individual boy and girls can be changed.
So, there are 5 girls and 5 slots for them that means they can be arranged in 5! ways,
similarly boys have 4 slots, so they can be arranged in 4! ways.
now, one more thing to consider is that out of 5! arrangements of girls, with each arrangement boys can be arranged in 4! different positions.
so to get the total number of boys and girls arrangements together we would need to multiply the arrangements of both boys and girls.
so the desired answer would be: 5!*4! = 120*24 = 2880 ways.
All you have to do is add exponents when multiplying like monomials. So it's just 4^2

Answer:
x = 250,000
Step-by-step explanation:
A = P(1 + rt)
550,000 = x (1 +2% x 60)
550,000/(1 +2% x 60) = 250,000
x = 250,000
<u>Check your answer</u>
A = 250,000 (1+2%x60)
A = 550,000
