Answer:
90 minutes
Step-by-step explanation:
let x=amount of time it would take for Shelby to knit the scarf
cross multiply
15*30=5x
450=5x
450/5=x
x=90
It would take Shelby 90 minutes to knit a scarf that is 30 inches long.
Answer: 525 cycles per second.
Step-by-step explanation:
The equation for inverse variation between x and y is given by :-
(1)
Given : The length of a violin string varies inversely with the frequency of its vibrations.
A violin string 14 inches long vibrates at a frequency of 450 cycles per second.
Let x = length of a violin
y= frequency of its vibrations
To find: The frequency of a 12 inch violin string.
Put in equation (1) , we get
Divide both sides by 12 , we get
Hence, the frequency of a 12 inch violin string = 525 cycles per second.
