There are 3 students to 1 adult on a field trip. you need to find the number of adults needed for 24 students. what would the second ratio of the proportion look like if the first proportion is as follows: (s is just short for students, and a is just short for adult cause it would make the fraction look weird if i didn't use letters). 30 ! (a) 3s/s (b) 3/1 (c) 24s/x (d) 1/3 (e) x/24s

a = 24*1/3

a =8  

Step-by-step explanation:

We are using proportions to solve this problem by putting students over adults

students         3                   24

=  =

adults                 1                   a

where a is the unknown number of adults

Using cross products

3a=24*1

Divide by 3

a = 24*1/3

a = 24/3

a = 8

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
