Answer:
4/9
Step-by-step explanation:
Given rate is 1/3 acre per 3/4 hours.
To calculate the rate per hour, we have to divide total acres by the fraction of hour
=>
=>
=> 4/9
Two fire rangers in watch towers that are 10 miles apart spotted a fire at the same time. The first ranger indicated that the po
sition of the fire made an angle of 39° with the line between the towers. The second ranger indicated that it made an angle of 34° with the same line. How far is the second tower from the fire?

<h3>What is the combination formula?</h3> is the number of different combinations of x objects from a set of n elements, given by:
Exercise 1, item a:
One letter from a set of 7, hence:
7 combinations are possible.
Item b:
Two letters from a set of 7, hence:
21 combinations are possible.
Item c:
7 letters from a set of 7, hence:
1 combination is possible.
Question 2:
Three singers are taken from a set of 7, and four dances from a set of 10, hence:

When in doubt, graph it.
The 3rd and 4th choices are appropriate.
_____
This is what is known as a "logistic function." It is used to model population growth when there is a resource limit. It starts out exponential, but then slows as it reaches the "carrying capacity" of the environment. The lower asymptote is zero; the upper one is the carrying capacity of the resource--here 15/1 = 15.
