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? Explain a strategy you used to solve this problem.

40%

Step-by-step explanation:

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

(Number of dissatisfied students/Total number of students) × 100

= 192/480 × 100

= 40%

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

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
