What does 1/4 of a can of coffee cost if 4 cans of coffee cost $1.60

Answers

Answer 1

Answer:

We know that 4 cans of coffee cost $1.60. So, if we divide that number by 4, we get

$4\text{ cans of coffee} = 1.60 \iff \frac{4\text{ cans of coffee}}{4} = (1.60)/(4) \iff 1 \text{ can of coffee} = 0.4$

Now we can simply repeat this process again: if we divide both sides by 4, we get

$1 \text{ can of coffee} = 0.4 \iff \frac{1 \text{ can of coffee}}{4} = (0.4)/(4) \iff (1)/(4)\text{ cans of coffee} = 0.1$

What is equal to the expression square root of 40/2

Answers

First you would simplify what's in the square root, to get root 20. If you want the exact number, and not the approximation, you would take out whatever squares are in that number (20=2*2*5) so your answer is 2root5.

However, if you want the approximation, simply plug it into your calculator and get 4.18154055.
