1. The speed of sound in water is 1,500 meters/second. How far can sound travel in 10
baherus [9]

Answer:

  • 900 km
  • 5400 km

Step-by-step explanation:

<u>The speed of sound in water:</u>

  • s = 1500 m/sec

<u>Time:</u>

  • t = 10 min = 10*60 sec = 600 sec

or

  • t = 1 hour = 60 min = 60*60 sec = 3600 sec

<u>Distance in 10 min:</u>

  • d = s*t
  • d = 1500 *600 = 900 000 m = 900 km

<u>Distance in 1 hour:</u>

  • d = 1500*3600 = 5 400 000 m = 5400 km

Use the graph to the right to write an equation of the line. What is the equation?​
Bingel [31]

Answer:

y = 1/4 x - 2

Step-by-step explanation:

To write the equation of a line, find from the line the slope and y-intercept. The y-intercept is where the line crosses the y-axis which here is at point (0,-2).

The slope of the line is found by writing a ratio between the vertical distance and the horizontal distance between points.

Slope is 1/4.

Substitute m = 1/4 and b = -2 into the slope intercept form y = mx + b.

y = 1/4 x - 2
