BRAINLIST, EXTRA POINTS, FIVE STARS, AND A HEART

PLEASE HELP!

800

Step-by-step explanation:

We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%

Cross multiply and solve:

240 * 100 = 30x

24000 = 30x

800 = x

can you give me more detail on this! ?

step-by-step explanation:

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
