STEP 1:
Add the number of total students
= 27+25+23
=75


STEP 2:
Find the percentage that 18 out of 75 students is.

18/75=x/100

cross multiply
(18*100)=(75*x)

1800=75x
divide both sides by 75
24%=x

Check:
75 * 24%= 18

Hope this helps! :) Good luck!

Need help ASAP!! Write an informal proof to show triangles ABC and DEF are similar.
yaroslaw [1]

Answer:

Δ ABC and Δ DEF are similar because their corresponding sides are proportional

Step-by-step explanation:

Two triangles are similar if their corresponding sides are proportional which means the corresponding sides have equal ratios

In the two triangles ABC and DEF

∵ AB = 4 units

∵ DE = 2 units

∴ \frac{AB}{DE}=\frac{4}{2}=2

∵ BC = 6 units

∵ EF = 3 units

∴ \frac{BC}{EF}=\frac{6}{3}=2

∵ CA = 2 units

∵ FD = 1 units

∴ \frac{CA}{FD}=\frac{2}{1}=2

∴ \frac{AB}{DE}=\frac{BC}{EF}=\frac{CA}{FD}=2

∵ All the ratios of the corresponding sides are equal

∴ The corresponding sides of the two triangles are proportional

∴ Δ ABC is similar to Δ DEF
