We need to find the absolute value of these numbers to see which one is closer to the surface of the ocean. The surface of the ocean is at 0.

Trina : | - 85.5 | = 85.5 meters from 0
Jessie : | 87.9 | = 87.9 meters from 0

so Trina is closer to 0 then Jessie is. <==
The reason we took the absolute value of these numbers, is because that is what the absolute value does...it tells us how many spaces away from 0 it is.

Frequency=(speed of sound)/(wavelength)
that means
wavelength =(speed of sound )/(frequency)
speed of sound=344 m/s

4.
frequency=587. 33 Hz
thus
wavelength=344/587.33
=0.586 m


5.
frequency=493.88 nHz
thus
wavelength=344/493.88
=0.69653 m

6. Frequency= 698.46 Hz
wavelength= 344/698.46
wavelength=0.4925 m

9. Frequency =783.99 Hz
wavelength=344/783.99
wavelength=0.439 m

Find a number that is 96 greater than its opposite
BartSMP [9]

For this problem you'll get a number, find it's opposite and sum 96 to it. The equation used will be:

x = -x + 96

Where:

x = a number

-x = the opposite of x

So:

x = -x + 96

x + x = 96

2x = 96

x = 96 / 2

x = 48


And now, if you do the sum to prove your answer:

48 - 96 = -48


Answer:

\boxed{\bf~48~is~the~number}



Hope it helped,
