There are 120 athletes register at the club.
If 48 athletes are girls, determine:

1. the number of girls in the club as a percentage of the total number of registered
athletes

2. the ratio of girls : boys registered at the club.​

1. the number of girls in the club as a percentage of the total number of registered

athletes -

2. the ratio of girls : boys registered at the club. : -

=》2 : 3

Step-by-step explanation:

here's the solution : -

percentage of girls in the club :

=》

=》

=》

=》

so, 40 % of athletes are girls.

now,

number of boys = 120 - 48 = 72

ratio of girls : boys : -

=》

=》

so, their ratio = 2 : 3

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
