Antonio is standing on a at the edge of a canyon. He yells loudly and hears an echo 1.2 s later. How far away is the other side of the canyon? You may assume the speed of sound is 340 m/s.Russell is watching a thunderstorm. He hears the thunder 5 s after seeing a flash of lightning. How far away was the lightning?

Answers

Answer:

  • 204 m
  • 1700 m

Step-by-step explanation:

a) In 1.2 seconds, sound will travel a distance of ...

  (1.2 s)(340 m/s) = 408 m

This is the round-trip distance, so the reflecting surface is half that distance away.

The other side of the canyon is 204 m away.

__

b) In 5 seconds, the sound will travel a distance of ...

  (5 s)(340 m/s) = 1700 m

This is the one-way distance, so the lightning is about 1700 m away.

A coin-operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, 15 green rings, and 3 black rings. Suzy puts a coin into the machine. Find the theoretical probability that she will get a green ring. Express your answer as a fraction in simplest form.

Answers

1) you have to add all the rings together to find the denominator

6 + 11 + 15 + +3 = 35

2) the numerator is the amount of rings of the certain color you are trying to find the probability of

15

3) find the theoretical probability! 15/35

4) simplify

15/35 (divide both by 5) = 3/7

Help me solve this please 33+15w=3w-w+4w

Answers

Answer:

33+15w=3w-w+4w

33+15w - 15w=3w-w+4w -15w

33 = 2w + 4w -15w

33 = 6w -15w

33 = -9w

33/9 = -9/9w

3.66 = w

Step-by-step explanation:

33+15w=3w-w+4w

33+15w - 15w=3w-w+4w -15w

33 = 2w + 4w -15w

33 = 6w -15w

33 = -9w

33/9 = -9/9w

3.66 = w

Using the order of operations rule, solve the following: 12 ÷ 2 + 4 – 2 × 3 = ? A. 24 B. 36 C. 0 D. 4

Answers

the answer is D, because you have to divide 12 by 2 so you get 6 then 2 times 3 to get 6, so now you should have 6+4-6 which will then become 10-6 which equals 4 
Use\ PEMDAS:\n\n\underbrace{12:2}_(=6)+4-\underbrace{2*3}_(=6)=6+4-6=10-6=\boxed{4}
