Answer:

6½ gallons

Step-by-step explanation:

Givem the cost of 1gallon of gas = $2.78. . If Cory buys $18 of gas, we are to find the number of gallons did he buy. To do that we will use the equality method as shown;

$2.78 ,= 1gallon

$18 = x gallon

Cross multiply

2.78 × x = 1×18

2.78x = 18

Divide through by 2.78

2.78x/2.78 = 18/2.78

.x = 6.5

Hence Cory buys about 6½ gallons of gas for $18

A. in terms of the number of marked elk, what is the relative frequency of male elk, female elk, adult elk, and baby elk? write

mash [69]

The relative frequency of the marked elks are:

Male Elk = 7/30
Female Elk = 4/15
Adult Elk= 173/450
Baby Elk = 26/22

<h3>How to determine the relative frequency?</h3>

From the complete question, we have:

Male = 105
Female = 120
Adult = 173
Baby = 52
Total = 450

The relative frequency of each is then calculated as:

Male Elk = 105/450

Male Elk = 7/30

Female Elk = 120/450

Female Elk = 4/15

Adult Elk= 173/450

Baby Elk = 52/450

Baby Elk = 26/22

<h3>The number of Elks in the park</h3>

Using the data in (a), we can conclude that:

There are 105 male, 120 female, 173 adult, and 26 baby in the park

Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle \frac{x^2 - 10x - 24}{x^2 - 3x - 108}$ <u />

<u />

<u>Step 2: Simplify</u>

[Fraction] Factor numerator: $\displaystyle \frac{(x - 12)(x + 2)}{x^2 - 3x - 108}$
[Fraction] Factor denominator: $\displaystyle \frac{(x - 12)(x + 2)}{(x - 12)(x + 9)}$
[Fraction] Divide: $\displaystyle \frac{x + 2}{x + 9}$

We know that <em>x</em> cannot equal -9 because we would get a divide by 0 (undefined) error. We also know that <em>x</em> cannot equal 12 because it was canceled out when simplifying.
