Answer:
52 ft^2
Step-by-step explanation:
To find the area you just multiply 13 feet (length) by 4 feet (width). This gives you 52 feet squared because we are dealing with area and square feet.
Answer:
The answer is 14 1/2.
Step-by-step explanation:
The reason this is the answer is because once you add it all up u get 13 31/36 and estimated it is closer to thats than any other answer choice.
In this situation, say that you're leaving the basket at the distance it's presently at, one of the bottom of three is the best choice.
Answer:
After about 9 minutes.
Step-by-step explanation:
We can write an exponential function to model the decay of Herodium-100.
We are given that it decreases by half every minute.
The standard exponential function is given by:
Where A is the initial amount, r is the rate, and m is the rate (in this case, in minutes).
Mathman initially has 2000 mL of Herodium-100. Therefore, A = 2000.
And since it decreases by half every minute, r = 1/2. Thus:
Mathman needs to rest when the Herodium-100 levels drop to 4 mL. Therefore, we can substitute 4 for f(m) and solve for m:
Solve for m. Divide both sides by 2000:
We can take the natural log of both sides:
By logarithm properties:
Therefore:
Mathman will have to rest and replenish after 9 minutes.
Answer:
<h2>131.9</h2>
Step-by-step explanation:
C = 2πr
using 3.14 for π, we get C = 2(3.14)(21)
C = 2(65.94)
C = 131.88 or about 131.9
