There are between 24 and 40 students in a class the ratio of boys to girls is 4: 7 how many students in the class

33 students

Step-by-step explanation:

nr of boys-b

nr  of girls-g

b/g=4/7  

*7       *7

7b/g=4

*g       *g

7b=4g

we know  b+g=2440  

                 *4         *4

 4b+4g=between 96(24*4)   and 160(40*4)

but  4g=7b

4b+7b= 96160

11b=96160

but  multiple of 11  could be 99,110,121, 132, 143, 154

then b could be 9,10,11,12,13 or 14

if  b=12  

7b=4g so 7*12=4*g then   g=7*12/4=84/4=21

then  12+21=33  students

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
