Work week = 40 hours

Paid 7.50 an hour.

Sells 6300 worth of goods.

Equation

Take home pay = Sales * 5% + 7.50 * number of hours.

Sub and Solve

Take home pay = 6300 * 5% + 7.50 * 40

Take home pay = 6300 * 5/100 + 7.50 * 40

Take home pay = 315 + 300

Take home pay = 615 dollars.

The illuminance of a surface varies inversely with the square of its distance from the light source.If the illuminance of a surf

VashaNatasha [74]

Answer:

Distance between the surface and source of light will be increased by 6 meters.

Step-by-step explanation:

The illuminance of a surface varies inversely with the square of ts distance from the light source.

Let illuminance of the surface = x lumens per square meter

and distance from a light source = y meter.

Now x ∝ $\frac{1}{y^{2} }$

Or $x=\frac{k}{y^{2} }$ [k = proportionality constant]

Now we will find the value of k.

k = xy²

k = 120×(6)²

k = 4320

We have to calculate the distance of the source if illuminance of the surface is 30 lumens per square meter.

$30=\frac{4320}{y^{2}}$

y² = $\frac{4320}{30}$

y² = 144

y = √144 = 12 meters

So the source of the light will be shifted away from the surface = 12 - 6 = 6 meters.
