The usefulness is that this data allows you to understand how well students perform with their instruction, based on a standardized test. The limitation is that the scores don't account for different situations that may affect the results you receive.
Answer:
length=50m
width=25m
Step-by-step explanation:
perimeter is the distance all round,hence
2(l+w)=2(2x+x)=
4x+2x=6x=150
6x=150x
x=25
l=50m
w=25m
Then he slept 9 times. Because every hour is 60 minutes, since 1/3 of an hour is 20 mins, it should be 3 times per hour. So using basic math, 3 times 3 equals 9
23/4
If you divide the numerator and denominator by 2, you get simplest form.
