Answer: x =
5*sqrt(10)"sqrt" stands for "square root"

Refer to the attached image. The figure is not to scale. Notice how I've added in y and z (blue and red respectively)
The length y is the bottom horizontal leg for the triangle on the right.
The length z is the bottom horizontal leg for the triangle on the left.
To find x, we need to find y first, which will help us find z, and then we can finally get to x.
Let's find y first
To do this, we use the pythagorean theorem
a^2 + b^2 = c^2
y^2 + 9^2 = 15^2
y^2 + 81 = 225
y^2 + 81-81 = 225-81
y^2 = 144
sqrt(y^2) = sqrt(144)
y = 12 ... keep in mind that y is a length, so it needs to be positive
Notice how the y and z lengths combine to form a total length of 25 units
Therefore,
y+z = 25
12+z = 25
12+z-12 = 25-12
z = 13
Now that we know z = 13, we can find x. Again we use the pythagorean theorem one last time
a^2 + b^2 = c^2
z^2 + 9^2 = x^2
13^2 + 9^2 = x^2
169 + 81 = x^2
250 = x^2
x^2 = 250
sqrt(x^2) = sqrt(250)
x = sqrt(250)
x = sqrt(25*10)
x = sqrt(25)*sqrt(10)
x = 5*sqrt(10)This is in simplest radical form as we can't factor 10 any further (there are no perfect square factors that go into 10). This is the exact length of side x
Note: using a calculator,
5*sqrt(10) = 15.8113883008419 approximately
Answer:
98/76= (rounded to the nearest thousandth) 1.289.
2/5 and then when you graph it’s rise 2 and over 5
<h2>Answer:</h2>
a) 20 will represent the set price of admission
b) 3 is the price of each ticket
c) x will be the total number of ticket bought
d) y will be the total amount of money spent.
<h2>Explanations:</h2>
The equation given is written in slope-intercept form of a line. The slope-intercept form is in the form y = mx +b
where
• m is the ,rate of change ,or slope
,
• b is the ,intercept, (constant)
Given the equation that represents the total amount of mney the hunter will spend expressed as y = 20 + 3x
a) Since 20 is a constant value, it is more like the initial price. Based on the question, 20 will represent the set price of admission.
b) 3 is the price of each ticket needed to go on the ride
c) x will be the total number of ticket bought for the rides
d) As mentioned earlier, y will be the total amount of money the hunter will spend for the ride including the admission price.
I got C. 92.08
I'm not 100% sure I did this right, but I took the money gained between years nine and eleven and divided it by 2. I tried a few other ways, but none of my answers were choices.
