4 7 of students at a school are boys. If there are 2723 students at the school, how many are girls? 5 9 of students at a school are girls. If there are 2367 students at the school, how many are boys?

1167 of them are girls in the first situation.

1052 of them are boys in the second situation.

Step-by-step explanation:

Since there are 2723 students at the school and 4/7 of them are boys, the number of boys:

→ 2723 x = 1556

The number of the girls = Total number of students - The number of boys

→ 2723 - 1556 = 1167

Since there are 2367 students at the school and 5/9 of them are girls, the number of girls

→ 2367 x = 1315

The number of the boys = Total number of students - The number of girls

→ 2367 - 1315 = 1052

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
