The six grade is holding a fundraiser were students will make and sell peace necklaces for $1.50 each each student is responsible for selling 12 necklaces and 1/4 of the profits will be donated to earthquake in hurricane relief efforts in puerto rico if there are 130 six graders how much profit will the class send to puerto rico after they pay 45 cents of the earnings for advertisement and supplies

$ 584.89

Step-by-step explanation:

so each student is responsible for selling 12 necklaces...and there are 130 studentsso thats (130 * 12) = 1560 necklaces

each necklace is 1.50so thats (1560 * 1.50) = 2340

profit = revenue earned - expenses

profit = 2340 - 0.45 = 2339.55

1/4 of the profit goes to Puerto Rico

1/4 * 2339.55 = 2339.55/4 = 584.887 rounds to $ 584.89 <==

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
