Your answer is 76m.
a^2+b^2=c^2
57^2+b^2=95^2
3249+b^2=9025
b^2=5776
Take sqr on both sides and you get:
b=76m
If he goes to bed at 9:00 pm, and wakes up at 10:00 am he will have slept 13 hours.
6 because 25%=1/4 of a number, and 6x4=24. So 1/4 or 25% of 24 is 6
The answer would be 35 99/100 because you cannot simplify 99/100
If the ends span from the 0 to the 15 meter mark, then the length of the pipe is 15 meters. However, you should report it using the right amount of significant figures. It is mentioned in the problem that millimeter marks are calibrated between meters. Since millimeter is 1/1000 of a meter, you should add three decimal places to the 15 meters. Hence, you should report it as 15.000 meters.
