During the election for class president, 120 of the students voted for Lindsay, and 280 of the students voted for sharif. 400 Students voted in total. What percent of students voted for Lindsay?

x=200

Step-by-step explanation:

let 'x' represent the total number of students

0.40x of the students voted for Gerardo

0.35x of the students voted for Leandro

0.25x of the students voted for Juju

70 students voted for Leandro:

0.35x = 70

by solving we find:

x = 200 students

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
