Answer:
Step-by-step explanation:
density is weight divided by volume. And the volume of a log is like a cylinder.
V=hpi(r^2) in this case
V=25(30)pi=750pi so
d=(42.63)/(750pi)
d=0.018 lb/in^3
Step-by-step explanation:
x+y=-12
x-y=-2
solve by simultaneous equations multiply the second equation by -1
-x-y=2
subtract both equations
y=10
x+10=-12
×=-22
75/8 ÷ 23/8
75/8 × 8/23
Both of the 8s will cancel
Answer: 75/23
The answer would be 4.6x10^3. You take the number of calves times the number of pounds of one calf (230) and get 4,600. Then move the decimal three to the left. Hope that helps!
