Answer:
y = 36x
Step-by-step explanation:
Given that y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x = 
, thus
k = 
= 
= 36
y = 36x ← equation of variation
My solution to the problem is as follows:
<span>day 1: 1
day 2: 0.6667
day 3: 0.5111
day 4: 0.4385 <-------
</span>
Therefore, <span>the probability that the animal is in the woods on fourth observation would be 0.4385.
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:
1550 instead of 1100
Step-by-step explanation:
20% of 1100 = 220
20% of 5500 = 1100 and then he went back and changed 5500 to 1550 and found 310.
20% of 1550 is 310
Since the area is length times width, the area is 5*(2x+7)
Answer:
29 = 16.4
30=
Step-by-step explanation:
The formula for finding a hypotenuse is a^2 + b^2 = c^2. Therefore, if you want to solve 29 you would do 13^2 + 10^2 = c^2.
13^2= 169
10^2=100
269+100 = c^2
368= c^2
So next, we have to do the square root of 368 which is 16.4.
Now for number 30, we know that it is a right triangle. So if we want to work with that, we have to find the angles of everything. We know that the sum of all angles in a triangle is 180. So a right angle is 90 degrees. We have 90 left over. Could you solve the rest?
