Answer:
157
Step-by-step explanation:
TSA OF TRIANGLE IS 180
13+10 IS 23
180-23 IS 157
Answer:
This is just multiplying not simplify.
Answer:
about 78 years
Step-by-step explanation:
Population
y =ab^t where a is the initial population and b is 1+the percent of increase
t is in years
y = 2000000(1+.04)^t
y = 2000000(1.04)^t
Food
y = a+bt where a is the initial population and b is constant increase
t is in years
b = .5 million = 500000
y = 4000000 +500000t
We need to set these equal and solve for t to determine when food shortage will occur
2000000(1.04)^t= 4000000 +500000t
Using graphing technology, (see attached graph The y axis is in millions of years), where these two lines intersect is the year where food shortages start.
t≈78 years
I think the formula for the volume of a cone is V=(1/3) x hπr².
r²= 9
1/3= 0.3
= 0.3 x 4 x 3.14 x 9
= 33.912
