Belinda bought a car one year ago.
lesya692 [45]

Answer:

$16,500

Step-by-step explanation:

The computation of the amount that should be paid for the car is shown below:

Since the car would be purchased one year ago

And, the value of the car would be decreased by 15% to $14025

So the amount that should be paid is

= $14025 × 100 ÷ (100 - 0.15)

= $16,500

Find an equation of variation where y varies jointly as x and the square of z, and where y=70, when x=21 and z=5.
Bezzdna [24]

Answer:

y = 181.75xz^2

Step-by-step explanation:

Given

y jointly varies to x and z^2

Required

Find the equation

We start by writing out the variation;

y\ \alpha\ xz^2

Write as equation

y = kxz^2

Substitute values of x,y and z

70 = k * 21 * 25^2

70 = k * 21 * 25 * 25

70 = k * 13125

Divide both sides by 7

\frac{70}{13125} = \frac{k * 131251}{13125}

\frac{70}{13125} = k

187.5 = k

k = 181.75

Substitute k in y = kxz^2

y = 181.75xz^2
