For this case, the first thing we must do is define variables.
x: amount of time Miguel uses to complete the task.
y: amount of time Maria uses to complete the task.
We write the system of equations:
x + y = 60
y = (1/2) x
Solving the system we have:
x = 40 minutes
y = 20 minutes
Answer:
it take her to wash them by herself about:
y = 20 minutes
Answer:
D
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × ( cancel the 2π )
= 12 × = 2π ≈ 6.3 ( to the nearest tenth ) → D
The growth rate is 25%
Initial population, P = 6
Growth rate, r = 25% = 25/100 = 0.25
Number of years, t = 10
Final population, A = ?
A = P * (1 + r) ^t
= 6 * (1 + 0.25) ^10
= 6 * 1.25^10
= 6 * 9.31
= 55.86
Approximately 56
Therefore, approximately 56 rabbits can be expected to exist after 10 years
The question is already answered the answer is 43.586.
Answer: Option 'B' is correct.
Step-by-step explanation:
Number of employees exceeded their sales quota = 17
Number of employees met their sales quota = 13
Number of employees didn't exceed their sales quota = 3
Now, we need to find the ratio of the number employees who exceeded their sales quota to the number of employees who didn't exceed their sales quota,
So, Option 'B' is correct.
