The ratio of the number of boys to the number of girls in a certain class is 8:5. if the number of boys in that class is 52 students . find the number of girls?​

34.5

Approximately= 35

Step-by-step explanation:

The ratio of the number of boys= 8

Ratio of number of girls= 5

Total ratio= 8+5=13

number of boys in that class =52

Let total number of students= X

Ratio of number of boys= 8/13 × X=52

= 8X/13 = 52

8X=13 × 52

8X= 676

X= 84.5

Then, the number of girls= (84.5-50)

34.5

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
