Mathematics

To compare let's use Algebra to see how much one ounce costs for each package:

1. <u>16 ounces </u>= <u>$.79 </u>
       1 ounce       $x

$x= 0.049

2. <u>32 ounces</u> = <u>$3.49</u>
     1 ounce         $x

$x = 0.109

Therefore, comparing #1 and #2, the first package is the better deal.

vampirchik [111]

Answer:

21. 162 (rounded to nearest thousandth)

Area of a sector: (degree/360) (pi*radius^2)

degree given= 97

radius= diameter/2 = 5

(97/360) (pi*5^2)

(97/360) (pi*25) = 21.16211718

Micah was asked to add the following expressions: 3x2−x−9x2+3x+2+−2x2+2x+5x2+3x+2 First, he combined like terms in the numerator
shtirl [24]

Micah was asked to add the following expressions:

\frac{3x^2-x-9}{x^2+3x+2} + \frac{-2x^2+2x+5}{x^2+3x+2}

First, he combined like terms in the numerator and kept the common denominator

First step is correct. He added the like terms in the numerator, because the denominators are same.

3x^2 -x -9 -2x^2+2x+5becomes x^2 +x -4

So he got , \frac{x^2+x-4}{x^2+3x+2}

In the next step, he cannot cancel out x^2 from the top and bottom . Because x-4 and 3x+2  are added with x^2

If we have x^2 is multiplied with other terms at the top and bottom , then we can cancel out x^2.

So Micah added the expression incorrectly. Final answer is not correct.
