Elaine is counting votes from a school election. There were 3 candidates running for president, and students either voted for 1 of those 3 or the didn't vote at all. If there are 860 students in the school and one-fourth of them voted for Serina, two-fifths of them voted for Sandra, and three tenths voted for Michelle, how many students did not vote?

$15 each

step-by-step explanation:

$45/3 children= $15 each

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
