An obtuse angle is an angle that is in between 90 degrees and 180 degrees. It looks like this
X^-n = 1/x^n
Your fraction becomes:
1/ {(m^5 t^2)(27m^6t^3)} now combine the powers in the denominator
1/ (27 m^11 t^5)
Answer:
<h2>Look at the photo I have sent</h2>
40 ton x 2000 = 80,000 pounds
320000/8000 = 40 pounds per person
Volume = Area * height
= (pi/4)*D^2 * h
= (pi/4)*(40)^2 * 30
= 37,680 mm3
so, the answer is (a)
