I'd be more than happy to help. Im a sophmore and Love math
40% x 70% will give you the answer in percent.
.4 x .7 = .28 He has a 28/100 chance or 7/25 chance (reduced).
The answer is c.) of the 6 grade students surveyed, 12% bring their lunches to school. suppose 24 6 graders do this. how many 6 graders are at school?
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
