Step-by-step explanation:
add all of them up, Julie, 6 + 12 + 3 + 4 = 25
there are 25 total students. now divide each of the number of people that speak that language by the total students
6/25 = .24 = 24%
12/25= .45 = 48%
3/25 = .12 = 12%
4/25 = .16 = 16%
Also, if you want to just check, see if the percentages add to 100%
Answer:
c=√74
Step-by-step explanation:
h=c
p=5
b=7
Using pythogorean theorem,
h^2=p^2+b^2
c=√(7^2+5^2)
c=√(49+25)
c=√74
1. The value of x is 4. X + 4 = 4 + 4 = 8
