What magic trick??
Are you gonna do a magic??
Sorry for a lot of questions.
Notice they are all right triangles. You will need Pythagorean theorem, which is a² + b² = c²
If you write down all the "equations" you can find, it is the following:
y² + 4² = x²
5² + y² = z²
x² + z² = 9²
Substitute them into one equation:
y² = x² - 4²
z² = 5² + (x² - 4²) <em>Notice that the y² is replaced with what you found </em><em>above</em>
x² + (5² + x² - 4²) = 9² <em>Notice that the z² is replaced with what's </em><em>above</em>
Now that it is just one line with one variable, you should be able to find value of x easily.
The answer is 6 if my calculations are correct.
Question 32):
<u>Least To Greatest:</u>
-7/2, -2.8, -5/4, 4/3, 1.3
<u>Number of Inputs: </u>
<u>5</u>
<u>Ascending Order (Least to Greatest)/Smallest to Largest: </u>
-7/2, -2.8, -5/4, 1.3, 4/3
<u>Descending Order (Greatest to Least/Largest to Smallest):</u>
4/3, 1.3, -5/4, -2.8, -7/2
Hope that helps!!! : )
1/9 possibility; theres 1 and 4, 2 and 3, 3 and 2, 1 and 4. That makes 4 combinations. 6 sides on each die so the possibility of getting a sum of 5 out of two dice is 4/36 or 1/9.
(2^8 . 5^-5 . 19^0)^-2
using PEMDAS
this = (2^8 * 1/5^5 * 1)^-2
= (5^5 / 2^8)^2
= 5^10 / 2^16
