Brand X costs $2.70 for 10 ounces. Brand Y costs 4 cents more per ounces. What is the cost of 11 ounces of brand Y?

Ksju [112]

Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.

Is the point P (2,8) on the inside or outside of the circle described with equation x^2+y^2=100?

kykrilka [37]

Points $(x,y)$ on the circle satisfy $x^2+y^2=100$ .

Points inside the circle satisfy $x^2+y^2$ .

Points outside the circle satisfy $x^2+y^2>100$ .

We have

$2^2+8^2=4+64=68$

so the point (2, 8) lies inside the circle.
