If the hypotenuse is 41 inches, and one of the legs is 40 inches, what is the length of the other leg in inches?

Hyp² = 1leg² + 2leg²

41² = 40² + 2leg²

leg² = 1681-1600

leg = √81

leg = 9

the last choice

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
