Could 7.7 cm, 4.0 cm, and 1.7 cm be the side lengths of a triangle?
Choose 1
Yes
No

Only applicable if the triangle is right (a 90° angle measurement in one corner).

Using Pythagorean’s theorem, that can be answered.

(4.0)^2 + (1.7)^2 = 18.89

(7.7)^2 = 59.29

The legs A and B do NOT equal a hypotenuse of C, so the answer is NO.

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%
