Answer:

2.73

Step-by-step explanation:

It is given that Lisa paid 43.95 for 16.1 gallons of gasoline.

So, the cost of 16.1 gallons of gasoline is 43.95.

Hence, the cost of gasoline per gallon is 43.95/16.1 = 2.7304347.

Now, it is required to round this value to the nearest hundredth.

Therefore, the cost of gasoline per gallon rounded to the nearest hundredth is 2.73. (Answer)

17. A warehouse has 5 shelves long enough to hold 8 boxes and high enough to hold 4 boxes. All the shelves are full. How many bo

Sav [38]

Answer:

<h3>Total 20 boxes are there. </h3>

Step-by-step explanation:

Total number of shelves in a warehouse = 5 shelves.

Each shelve either can hold maximum 8 boxes with their lengths or can hold 4 boxes with their heights.

So, in that case only 4 boxes could be hold in each of 5 shelves because only 4 boxes could be fit with their heights.

Therefore, total number of boxes = 5 × 4 = 20 boxes .

<h3>Therefore, total 20 boxes are there. </h3>

The cost of a floral bouquet after a discount is applied is represented by the function below, where x represents the number of

galina1969 [7]

The average rate of change over the interval $(12,24)$ is 2.17

Explanation:

Given that the cost of a floral bouquet after a discount is given by the function $f(x)=2.17x-10.00$

We need to determine the average rate of change over the interval $(12,24)$

The average rate of change can be determined using the formula,

$\frac{f(b)-f(a)}{b-a}$

where $a=12$ and $b=24$

Substituting the value of a and b in the function, we get,

$f(12)=2.17(12)-10.00$

$=26.04-10.00$

$=16.04$

$f(24)=2.17(24)-10.00$

$=52.08-10.00$

$=42.08$

Hence, substituting these values in the formula, we get,

$\frac{f(b)-f(a)}{b-a}=\frac{42.08-16.04}{24-12}$

Simplifying, we get,

$\frac{f(b)-f(a)}{b-a}=\frac{26.04}{12}$

Dividing, we have,

$\frac{f(b)-f(a)}{b-a}=2.17$

Thus, the average rate of change over the interval $(12,24)$ is 2.17
