Hello from MrBillDoesMath!
Answer:
sqrt(105)
(which is approximately 10.25 centimeters
)
Discussion:
Call the unknown leg"a". From the Pythagorean theorem
8^2 + a^2 = 13^2 => subtract 8^2 = 64 from both sides
a^2 = 13^2 - 64 => as 13^2 = 169
a^2 = 169 - 64 = 105 => take the square root of both sides
a = sqrt(105) which is approximately 10.25 centimeters
Thank you,

Hope this helps! :)
The first card has to be 25 or less, which is 50% and the next card has to be a single card, which is 1/49. This will give you the answer of 1/98
First of all, we know that it's a linear equation, which means it'll have to be y=mx+b.
Identify your points.
(0, 0) and (5, 4).
Now find the slope by doing
m = (y₂ - y₁)/(x₂ - x₁)
m = (4 - 0)/(5 - 0)
m = 4/5
So the slope is 4/5 or 0.8.
Now set the equation up. You have a point and the slope, so use the point-slope equation.
y - y₁ = m(x - x₁)
y - 4 = 4/5(x - 5)
y - 4 = 4/5x - 4
y = 4/5x
So the equation of the line is y=4/5x.
