Answer: 
Step-by-step explanation:
The weight of Ana's dog at the time of its birth= 
By age 4, the dog weighed 6 times as much.
Now, the weight of Ana’s dog at age 4 =
Since, 
The weight of Ana’s dog at age 4 = 
Answer:
4) No, because over the long run your expected value is less than the cost to play
Step-by-step explanation:
The expected value is ...
0.51×0.99 + 0.49×1.01 = 0.5049 +0.4949 = 0.9998
This expected value is less than the cost to play, so you will lose money in the long run. You should not play.
Given that y varies inversely as x then:
y=k/x
where
k is the constant of proportionality given by:
k=yk
but
y=27 when x=2
thus
k=27×2=54
hence the function will be:
y=54x
The value of x when y is 9 will be:
9=54x
thus
x=9/54
x=1/6
3/4 is the ratio of woodwinds to to brass players
The equation for a circle is as followed:

where the center of the circle is at (h,k) and the radius of the circle is r.
We are given (h,k) and need to find the radius. To do so, we can use the distance formula to find the distance from the center to the point on the circle:

Plug in the two points:



If the distance from the center to the edge of the circle is the square root of 117, then r^2 = 117.
The answer is:
