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
Answer: n = 11
Step-by-step explanation:
2^10 = 1,024
1,025 + 1,025 = 2,048
2^11 = 2,048
I think it does equal x but not really fully sure
Answer:
x= 24
Step-by-step explanation:
Quotient means divide, increased means add
x/3 + 12 =20
Subtract 12 from each side
x/3 +12-12 = 20-12
x/3=8
Multiply each side by 3
x/3 * 3 =8*3
x= 24
Answer:
4.4444 percent.
Step-by-step explanation:
1cm = 10mm
So 9cm would equal out to 90mm ...
4 mm would be 4.44 percent of the 9cm.
is (4) % (?)
of (90) 100
Cross X mutiply and divide..
4x100 = 400
90 x % = 90... & 400 divided by 90 = 4.444
