Answer:
195 m.
Step-by-step explanation:
The time for the sound waves to reach the fish is 0.26/2 = 0.13 seconds.
Distance = speed * time
= 1500 * 0.13
= 195 m.
Answer:
10 degrees

The y intercept of the left graph is 2 and the y intercept for the right graph is -0.5. These are the points where the line cross the y-axis (the vertical axis)
<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k = 
= 
= 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
