1 is b) because, 1 3/4 - 2/4(which is the same value as one half) = 1 1/4. I'm genral to be able to subtract different fractions the denominator which is the number on the bottom has to be the same for the fractions if you are adding or subtracting. But for multiplication you just multiply across.

Need help with this question about amplitude

lesantik [10]

Step-by-step explanation:

the amplitude is the height of the wave.

like with sound - the further away you are, the lower the volume of the sound (as the sound volume is the indicator of the amplitude of a sound wave, or the brightness of a light is the indicator of the amplitude of a light wave).

the same for any other type of wave (like the seismic wave of an earthquake).

so, the larger the distance, normally the smaller the amplitude.

The sum of the ages of Rudy and his father is 58 years. The difference in their ages is 32 years. How old is each ?

Anestetic [448]

Answer:

Rudy is 13 years old. Her father is 45 years old.

Step-by-step explanation:

It's very simple actually!

All you need to do is subtract 32:

58 - 32 = 26

Then divide:

26 ÷ 2 = 13

13 is Rudy's age. Let's find her father's age!

We then add 32 back to 13:

32 + 13 = 45

And there you have it!

Hope this helped! :)
