Answer:

The last one

Step-by-step explanation:

If you were to multiply each of the numbers by 10, you would get

9cm, 12cm, 15cm.

If you divide by 3,

3cm, 4cm, 5cm.

That is a 3-4-5 triangle, and that is a pythagoren triple.

Since we mulitplied and divided the same for all 3 numbers, it still works for the original triangle (0.9, 1.2, 1.5)

A sports store sells 42 pairs of running shoes per day for $ 10.00 each. The owner estimates that for each $ 2.00 increase in pr
Setler [38]

Answer: $26

Step-by-step explanation:

Let the number of $2 price increases be x.

This means that if the price is 10+2x, 42-2x shoes are sold.

So, the revenue is (10+2x)(42-2x).

To maximize profit, we must maximize revenue.

(10+2x)(42-2x)\\\\=-4x^2 +64x+420

The maximum is at x=-\frac{64}{2(-4)}=8, so the price should be 10+2(8)=$26.
