The Picture and Sound electronics store has hired Kiara to work in the warehouse. She uses a pulley with a hand crank to lift heavy boxes. There is a
proportional relationship between the number of times Kiara turns the crank to
lift a box, x, and the height the box has been lifted (in feet), y.
She turns the crank 4 times to lift a box 3 feet. Write the equation for the relationship
between x and y.
Y-

ok then what happened.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
