1.A wave has a frequency of Hz and a wavelength of 30m. What's it's speed? 2. If the speed of a wave is 140m/s and it's frequency in 3 Hz, what is it's wavelength?

3. An ocean wave has a length of 15 meters. A wave passes a fixed location every 4 seconds. What is the speed of the wave?

4.A sound wave in air has a frequency of 260 Hz and travels at a speed of 330 m/s. What is the wavelength of this wave?

SHOW YOUR SOLUTION PLEASE

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
