Answer: 55
Explanation: The time that Nicole practiced in 5 WEEKS is 2030 minutes. If you want to know how many minutes she did per DAY, you should first convert 5 weeks into 35 days, since there 7 days in a week. Now, you can divide 35 from 2030, which will give you 55 minutes per DAY.
Step-by-step explanation:
Start by finding when the populations become equal.
C = R
1000e^(0.1t) = 50e^(0.5t)
Divide both sides by 50.
20e^(0.1t) = e^(0.5t)
Divide both sides by e^(0.1t).
20 = e^(0.4t)
Take natural log of both sides.
ln 20 = 0.4t
Multiply both sides by 2.5
t = 2.5 ln 20
t ≈ 7.5
The population of rabbits first exceeds the population of crickets in the middle of the 7th year after 2016, or 2023.
The answer is B. 36.
the ratio is 4:2, the number 4 is twice as much as 2. so if there's 18 algebra problems (representing the 2 in the ratio), then there would be twice as many data analysis problems. 18 times 2 equals 36. :) hope it helps!
Y=2x+5 assuming that you meant A(1,7)
Use slope formula rise/run
