Question:

My mother's age is three times my age. The sum of our ages is 40. How old am I? How old is my mom? (Hint: Let x be your age)

Ben O.

Answer:

We start by letting x be my age. My mother will therefore be 3 * x =3x The sum of our ages is therefore; 3x + x = 40 4x=40 Divide both sides by 4 4x/4 =40/4 We therefore get; x=10 My mother is 3x, so this becomes 3 x 10 =30 Answers; I am 10 years old Mom is 30 years old

Question:

The frequency of a wave is 250 Hz and the wavelength is 0.02m.What is the speed of the wave?

Ben O.

Answer:

To determine the speed of the wave we use the formula below; Speed=Frequency * Wavelength We then substitute the values given for frequency and wavelength.We therefore have; Speed=250*0.02 Speed=5 m/s
