15 computers for 45 students 45 computers for 135 students are they equal ?

I'm going to assume your talking about Ratios

so yes the ratios are equivalent

Step-by-step explanation:

we have to determine if each pair of ratios or rates is equivalent:

15 computers for 45 students

Ratio of computers to students= 15:45

                                                  = 1:3

45 computers for 135 students

Ratio of computers to students= 45:135

                                                  = 1:3

Hence, The ratio's are equivalent

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
