It will take 29.4 years for the population of Africa to be two times what it is today. This reflects: doubling time.
Doubling time is the time it takes for a particular amount of size or value to double at a given growth rate. By applying the 70 rules, we can find the doubling time of the exponentially increasing population. To do this, divide 70 by the growth rate (r).
Rule of 70 is a simplified way to determine the doubling time using the equation doubling time = 70 / r. Where r is the percentage growth rate of the population. For example, if the population of 10 species increases by 2 individuals per year, the r value will be 20%.

Answer:
The formula for the volume of a sphere is:
Sphere Volume = 4/3 • π • r^3
Sphere Volume = 4/3 • π • 7^3
Sphere Volume = 4/3 • π • 343
Sphere Volume = 1,436.7550402417 cubic inches

Answer:
8 students,
15 cans of juice and 11 packs of cheese cracker
Step-by-step explanation:
Mariam’s uncle donate 120 cans of juice and 90 - 2 = 88 packs of cheese cracker (eats two packs) for the school picnic.
Factor these numbers:
The greatest common factor is
so the greatest number of students who can share the food equally is 8 and each student will get cans of juice and 11 packs of cheese cracker.
Answer:
The last three,
2 cm, 5 cm, 6 cm
4 cm, 8 cm, 11 cm
10 in, 5 in, 13 in
As long as any two sides added together are long than the third side, it works as a triangle!
