Answer:

3.35

Step-by-step explanation:

Take the total cost and subtract off the cost of the tax

We need to determine the tax

71.02 = original cost + original cos* tax rate

71.02 = original cost + original cost* .06

71.02 = original cost (1+ .06)

71.02 = original cost (1.06)

Divide each side by 1.06

71.06/1.06 = original cost before tax

67 = original cost before tax

Now to find the cost of each light bulb

Divide by the number of light bulbs

67/20=3.35

just olya [345]

Volume of the 1st package : 8.5x11x2 =187 in³

Volume of the 2nd package = 17.5x12x10 = 2,100 in³

Number of packages that fit = V₂/V₁ = 2100/187 = 11.23 Packages

What is the square route of 49

Katen [24]

7.

One way to figure this out is to go from 2-10, and multiply them by them self each other to see what number works.

Another way is to use a calculator and the square root button.

Hope that helps!

What is product of x/3 and 6/x when x=0 ? A.2 B.18 C.2/x^2 D.18/x^2

Ahat [919]

Answer:

A) But if anyone thinks this they should go back to preschool

Step-by-step explanation:

On any other value of x you would take the numerators and denominators and multiply them across:

$\frac{x}{3}*\frac{6}{x}=\frac{x*6}{x*3}=\frac{6}{3} =2$

But, this literally does not make since considering the fact that you cannot divide any value by zero. Try it, it won't work. If we plug these into a trusty dusty calculator, we get this:

$\frac{0}{3}=0\\\\\frac{6}{0}=DOMAINERROR$

0*DOMAINERROR= You can't do it.

There are other reasons why you can't divide by zero, I would suggest looking them up on YT and learning about them.

I would answer A, but the person who wrote this question just wasn't focusing when they wrote the question.
