Answer:
hello louser your a very crazy man
Step-by-step explanation:
Answer:
a^2 + b^2 = c^2
3^2 + b^2 = 5^2
9 + b^2 = 25
b = _/16
b = 4
Explanation:
Pythagorean Theorem
Answer: 2400
========================================================
Work Shown:
(80 push-ups)/(2 minutes) = (x push-ups)/(60 minutes)
80/2 = x/60
40 = x/60
40*60 = x
2400 = x
x = 2400
He can do 2400 pushups per hour, assuming he keeps at this same rate.
Answer:
49
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.Laura's design will be light enoughThe shape is given as a trapezium (see attachment).First, calculate the height (h) of the trapezium using the following Pythagoras theorem 52=h2+x2 Where: x=11−92=1 So, we have: 52=h2+x2 52=h2+1225=h2+1 Collect like terms h2=25−1 h2=24 Take square root sh=4.90The area of the shape is then calculated as follows: Area=12(11+9)×h Area=12(11+9)x4.90 Area=12×20×4.90 Area=10×4.90 Area=49
The area of the shape is 49 square inches.Hence, the shape will be light enough (because 49 is less than 80
