s tax. You can order them from an Internet shopping site that offers them for $3.50 each plus $5.95 shipping and no sales tax. The Internet store offers free shipping when you order a box of 12 for $40.00. Which of the following is the best deal?

Store=10*4*1.06=$42.40

Internet=10*3.5+5.95=$40.95

And if you order an extra two to cancel out shipping...

Internet=$40.00

So the box of twelve is the best deal as it costs less than the other two options and gives you two spare cables. :P

You can peel 48 potatoes in 10 minutes. How long will it take you to peel 100 potatoes?
dybincka [34]

Answer:

About 20.8 minutes

Step-by-step explanation:

TO solve this just think of it as a ratio. The number of potatoes goes on top and the time goes on bottom.

48

__

10

That is what the first one would look like. In the second one we know the number of potatoes but we are trying to find the time (x).

100

___

 x

Take these two ratios and set them equal to each other.

\frac{48}{10} =\frac{100}{x}      Next you cross multiply (take 48 times x and 100 times 10).

48x=1000    Now divide by 48 and you have your answer.

About 20.8 minutes

Solve for A if ñ=3.14 and r=3.
julsineya [31]

Answer:

28.26

Step-by-step explanation:

The question gives the first three digits of π, which is 3.14, and it gives us the radius, which is 3. So, just substitute them into the formula and you’ll get 3.14(3^2). Solve it and the final answer is 28.26.

Hope this helps! :)
