Answer:
98% is almost 100%, so we can see that the number of problems on the test can only be 1 or 2 more than 86.
The number of problems on the test is 87
Step-by-step explanation:
Answer:
For the first one, R would be = -3/5
In the decimal form that would be -0.6
For the second one, K = 2/19
In the decimal form, it would be 0.10526315
…
Step-by-step explanation:
Answer: the numerator is the top number(s) and the denominator is the bottom number(s)
Step-by-step explanation:
Answer:
1,041,958.5, or 104,195 1/2
Step-by-step explanation:
All you have to do is 15787.25 times 66, because 15787.25 is the price for on acre, so 66 acres will be 15787.25 times 66. If you want to put it in fraction form, you can do 15787 1/4 times 66. I hoped you liked this answer!
Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
