A right triangle has a hypotenuse of 32 cm and a base measurement of 8 cm. What is the length of its altitude leg to the nearest whole number?

1. 31 cm

2. 34 cm

3. 30 cm

4. 38 cm

1. 31

Step-by-step explanation:

a² + 8² = 32² (figure out what 8² and 32² equal)

a² + 64 = 1024 (subtract 1024 - 64)

a² = 960 (find the square root of 960)

√960 = 30.98 = 31  (round to the nearest whole number)

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%
