Answer:
250 students
Step-by-step explanation:
Let the number of sixth grade students be represented by = x
We were told that:
At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. 100 sixth-grade students prefer hip hop music.
Hence:
40% of x = 100
40/100 × x = 100
40x/100 = 100
Cross Multiply
40x = 100 × 100
x = 10000/40
x = 250
The number is sixth-grade students is 250 students
Before we calculate we can use some common sence thinknig to narrow down the choices. We know that Robert is gonig DOWN the hill, so it doesnt make sence that he woudl have a positive rate of change (i.e. the number feet up the hill he is is decreasing, not increasing) So right away, A & B are clearly wrong.
If we look at the last two (C & D) we can see that if -460 were right after 10 minutes he would have walked down 4,600 feet. This is WAY more that the total height of the hill and so can't be correct.
So C must be correct.
We can check this with some simple math:
