When all 480 sixth-grade students at Golden State Middle School were polled, results showed that 192 students were dissatisfied with the music played at the school dance. What percentage of sixth-grade students does this represent?

This is calculated as

= 40%

The percentage of sixth-grade students that this represents is 40%

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
