Question:

The quantities x and y are proportional.

x y

5.8 7.5

11.2

Find the constant of proportionality (r) in the equation y=rx

Answer:

The constant of proportionality is 75/58 or 1.29

Step-by-step explanation:

Given

The table above

Required

Find the constant of proportionality

The question has an incomplete table but it can still be solved because x and y are proportional.

Given that

y = rx

Make r the subject of formula

Divide through by x

y/x = rx

y/x = r

r = y/x

When y = 7.5, x = 5.8

Substitute these values

r = y/x becomes

r = 7.5/5.8

Multiply denominator and numerator by 10

r = (7.5 * 10)/(5.8 * 10)

r = 75/58

In this case, it's best to leave the answer in fraction.

However, it can be solved further.

r = 75/58

r = 1.29 (Approximated)

Hence, the constant of proportionality is 75/58 or 1.29

Jackie walks into a convenience store and recognizes the number of lottery tickets she can purchase varies inversely with the pr
OLEGan [10]
Let the price of the tickets be 'x' and the number of tickets bought is 'y'

When the y inversely proportioned to x, the equation is

y = k/x where k is a constant

We work out the value of k by using the information y = 6 and x = 5

6 = k/5
k = 30

Hence, the maximum number of tickets when the price is $3 is

y = 30/3
y = 10 tickets
