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 1

Answer:

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.

Lamont's buys 9 gallons of ice cream. He has 34 guests coming. If each guest eats 2 1/2 cups, how many pints will he have left?

Answers

We know that 1 gallon is equal to 16 cups.
So 9 gallons is 144 cups.
each guest eats 2.5 cups, and there are 34 guests,
2.5 times 34 = 85, the amount eaten by the guests.
So to figure out whats left, subtract the eaten from the total.
144-85=59
59 is the answer.

Find the coordinates of an image of point R(3, -5) rotated 180 degrees about the origin.

Answers

if it was rotated 180, then the siigns are switched becasue 180 is 1/2 of 360, so the signs are switched and you get (-3,5)

this was kind of easy so maybe I am wrong.

When you rotate a coordinate pair by 180 degrees you simply multiply the x and the y by a negative 1

so 3 x -1 and -5 x -1 will give you a new coordinate pair of (-3, 5)
