Density=m/V
m=80 gr
V=200cm^3
Density=80gr/200cm^3
Density=0.4 gr per cubic centimeter
Answer:
1680
Step-by-step explanation:
nPr = n!/(n-r)!
Therefore;
8P4 = 8!/(8-4)!
we get;
= 8!/4!
= (8×7×6×5×4×3×2×1)/(4×3×2×1)
= 40,320/ 24
= 1680
Answer:
I think this is the answer. I tried.
Step-by-step explanation:
13/10/4 = .325
A. 1,400 x .325=455
Net Price=1,400-455 = 945
B. Trade Discount = 32.5%
A=πr²
pool=π(y-4)²=π(y²-8y+16)
total=π(y+4)²=π(y²+8y+16)
walkway=total-pool
walkway=π(y²+8y+16)-π(y²-8y+16)=
π(y²+8y+16-y²+8y-16)=
π(16y)=
16πy
first option is answer
The square root of a circle would be your answer because 4.2-8
