Piper used 1/3yard of ribbon to create a border around a triangle. If the sides of the triangle are all the same length, how much ribbon did she use for each side

1/9 yards of ribbon

Step-by-step explanation:

triangle = 3 sides

since it has the same length sides, then

(1/3) / 3 = 1/9 yards, or

1/3 feet, or

0.1111111... yards, or

0.3333333... feet, or

4 inches

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%

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
