Answer:
Step-by-step explanation:
Given
--- average time
--- the variation
Required
The inequality to represent the scenario
To do this, we simply add and subtract the variation from the average time.
i.e.
So, the inequality is:
Solve:
Answer:
72π (I think)
Step-by-step explanation:
Think of it in terms of the entire circle. A semi-circle is just half a circle, so the area of a semicircle will be half of the area of the entire circle. The radius of the semicircle is 6, so the radius of the whole circle is 12. Then, we can do to get the area of the semicircle is 72π. I'm pretty sure that's right. Let me know if I made a mistake somewhere.
The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.
The cost of the dryer is $350.
Answer:
sample size at the beginning was 40 bacteria.
Step-by-step explanation:
Given that a sample of bacteria experienced 5% daily growth compounded continuously for 14 days
Let C be the initial amount of bacteria.
C grows continuously compounding at the rate of 5%
The equation representing the number of bacteria at time t days would be
Now we have t = 14 days and P = 80.
Substitute to get
Approximately 40 bacteria were present at the beginning.
