Let the number be x
The sum of 2 equal numbers is simply x+x or 2x.
The probability in faction form would be 25/80 simplified would be 5/16 chance of spinning a 3. The decimal form would be a 0.3125 chance in spinning a 3
D., Because 29 x 15 is 435 but if you throw the .07 in the mix you'll have 436.05 which breaks even.
This is a 30-60-90 triangle.
Therefore,
7 is A
the other leg is A√3
And the hypotenuse is 2A
So the other leg is 7√3 and the hypotenuse is 14
