Using algebra...
n and n+2 are the integers
n*(n+2)=288
n^2+2n=288
n^2+2n-288=0
288=2*2*2*2*2*3*3=(2*2*2*2)*(2*3*3)=16*18 and 18-16=2
factor
(n+18)(n-16)=0
n+18=0
n=-18
n+2=-16
this is one solution
n-16=0
n=16
n+2=18

this is another solution
as you can see, it's just a matter of factoring
288

using arithmetic...
√288=16.97≈17

16 and 18 are the integers (as well as -16 and -18)

Supper saver grocery carries a 128 ounce jug of iced tea. The nutritional label states that the jug serves 16 people . Which rat

frez [133]

Answer:

1:16 for every 16oz there is a 1 person serving.

Step-by-step explanation:

<em>"128 ounce jug of iced tea. The nutritional label states that the jug serves 16 people."</em>

16:128 is your given ratio, this is already a correct answer, but we will simplify by finding the GCF (greatest common factor) and dividing by that.

Factorization of 16 Factorization of 128

<em> </em> $\left[\begin{array}{ccc}16& & \\2&8& \\2 &4 & \\2 & 2\\2& 1 \end{array}\right]$ $\left[\begin{array}{ccc}128 \\2 &64\\2 &32\\2&16\\2&8\\2&4\\2&2\\2&1 \end{array}\right]$

The common factors we have are: 2x2x2x2 which is = 16 = GCF

so lets simplify our ratio by dividing by the GCF

$\frac{16}{16}:\frac{128}{16} = 1:16$
