Answer:
1012
Step-by-step explanation:
Given:
pitch 'p' = 460 vibrations per second
wavelength 'w'= 2.2m
'k' represent constant of variation
'k' can be determined by taking the product of pitch and wavelength
k= p.w
k= 460 x 2.2
k= 1012
Therefore,
the constant of variation is 1012
Set it up in a proportion.
15/ 58 = x/1450
cross multiply.
58 * x = 58x
15 * 1450 = 21750
divide
21750/58x = 375
the answer is b. 375
Answer:
3/4
Step-by-step explanation:
you would get 6/8 but need to simplfiy to 3/4 since they both can divide by 2
