Answer:
B
Step-by-step explanation:
Recommended for housing: 30%
X/100 = 612/1700
= 36%
Recommended for food: 10%
X/100 = 238/1700
= 14%
Recommended for transportation 15%
X/100 = 370/1700
= 21.8%
Answer:
Step-by-step explanation:
Sum of cubes is a^3+b^3=(a+b)(a^2-ab+b^2)
64x^3+1
(4x+1)(16x^2-4x+1)
You would do 3/4 of 20.
20 / 4 = 15
15 pens have black ink.
F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!
the angular speed is theta/time, which means
w=theta/time
but another formula for it is Velocity*radians
w=velocity*radians
velocity is 180 mph and radians are (revolution/2 radius), that is:
w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!
