Step-by-step explanation:
Answer:
Head=3cm
Body=12cm
Tail=5cm
Step-by-step explanation:
H= head
B=body
T=tail
B =4h
T=2+h
Total length= 20cm
20cm = b+t+h
20cm= 4h+(2+h)+h
20cm= 6h+2
18cm=6h
3cm=h
Body 4(3)=12
Tail= 2+3= 5
The world population is estimated to be nearly 9 billion by the year 2050.
Africa- 20%
What is the estimated population of Africa in the year 2050?
9 billion x 0.2 = 1.8 billion
Answer:
v(b) = 4,5 mil/h speed of the barge in still water
Step-by-step explanation:
d = v*t barge going upstream 12 miles and 4 hours trip
barge returning back 12 miles and 2 hours trip
let call v(b) barge velocity and
v(w) water velocity
d = 12 (Mil) = 4 (h)* [(v(b) - v(w)]
3 = v(b) - v(w) (1)
d = 12 (mil) = 2 (h) * [ (v(b) + v(w)]
6 = v(b) + v(w) (2)
Equations (1) and (2) is a two system equation. Solving
from equation (1) v(w) = v(b) - 3
By subtitution in equation (2)
6 = v(b) + v(b) - 3
9 = 2v(b)
v(b) = 9/2 ⇒ v(b) = 4,5 mil/h
Answer:
The inequality would be 4x + 9 ≥ 0
Step-by-step explanation:
You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.
