Liam is a tyre fitter.
Ronch [10]
A) 186 minutes
b) 3 tyres

We can take 124 and divide it by 4 to see how long it takes him to fit 1 tyre, then use that number to sort the rest out.

124/4 = 31

It takes Liam 31 minutes to fit one tyre to a lorry.

To fit 6 tyres, it takes 6 x 31 = 186 minutes

If he works for 93 minutes,
93/31 = 3 tyres

Please let me know if you have any questions.

zalisa [80]

Answer: 45,000.

Step-by-step explanation:

The equation of inverse variation is given by:-

k=xy

, where k is the constant of proportionality.

Given: After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.

Here,

x_1=3,\ y_1=15000\\\\x_2=5,\ y_2=9000

Then, k=x_1y_1=3\times15000=45,000

or k=x_2y_2=5\times9000=45,000  [answer is same in both cases.]

Hence, the constant of proportionality in this inverse variation is 45,000.
