Lisa paid $43.95 for 16.1 gallons of gasoline what was the cost per gallon rounded to the nearest hundredth

Final answer:

The linear function to describe the cost of using the pencil as a function of the number of refill packs Jorge buys is C(x) = 8 + 2x, where C(x) is the total cost and x is the number of refill packs.

Explanation:

Jorge bought a mechanical pencil for $8, and each lead and eraser refill pack costs $2. To describe the cost of using the pencil as a function of the number of refill packs, we can write a linear function. The initial cost of the pencil is a fixed cost, and the cost of each refill pack is a variable cost.

Let's let x represent the number of refill packs, and C(x) represent the total cost of using the pencil. The linear function for the cost would then be:

C(x) = 8 + 2x

Here, $8 represents the fixed cost (the cost of the pencil), and $2 is the cost per refill pack, so 2x represents the variable cost (the cost of x refill packs).

Final answer:

The linear function that describes the cost of using the pencil as a function of the number of refill packs is Cost(x) = 8 + 2x.

Explanation:

To write a linear function that describes the cost of using the mechanical pencil as a function of the number of refill packs, we need to consider the initial cost of the pencil and the cost of each refill pack.

Let's assume x represents the number of refill packs.

The initial cost of the pencil is $8, which remains constant regardless of the number of refill packs.

The cost of each refill pack is $2, and it increases linearly as the number of refill packs increases.

Therefore, the linear function that describes the cost of using the pencil as a function of the number of refill packs is:

Cost(x) = 8 + 2x

An equivalent fraction to 14/25 is 56/100, which is found by multiplying both the numerator and the denominator of the fraction by 4. This method is useful to express the fraction with a denominator of 100, illustrating its percentage form.

A fraction equivalent to 14/25, you can multiply both the numerator (top number) and the denominator (bottom number) by the same integer. As an example, if you multiply both by 4, you get 56/100, which is equivalent to 14/25. This is because the value of the fraction does not change when you multiply or divide both the numerator and the denominator by the same non-zero number. Multiplying by 4 is a standard way of expressing a fraction where the denominator equals 100. This process is useful for understanding percentages since a denominator of 100 directly shows the percentage.

Hence, An equivalent fraction to 14/25 is 56/100.

Answer:

Change of elevation =   163.

Step-by-step explanation:

Given : 134 feet below sea level to 29 feet above sea level?

To find : What is the change in elevation.

Solution : We have given

Below sea level = 134 feet .

Above sea level = 29 feet.

Change of elevation =  Above level -  below level.

We use positive sign for above level : + 29 feet.

We use negative sign for above level : -134 feet.

Change of elevation =  29  - (-134).

Change of elevation =  29 + 134).

Change of elevation =   163.

Therefore, Change of elevation =   163.

Answer:

The car completed 20% of the trip between the cities.

Step-by-step explanation:

The distance between Oswego and Syracuse = 40 miles

The car traveled from Oswego towards Syracuse = 8 miles

We have to calculate the percentage of the trip that the car completed.

8 miles out of 40 miles = [tex]\frac{8}{40}[/tex]

To calculate we have to multiply it by 100 and put the mark of percentage.

[tex]\frac{8}{40}[/tex] × 100

= 0.2 × 100 = 20%

The car completed 20% of the trip between the cities.

Jeff ate 2/5 of the entire pumpkin pie on Saturday, calculated by multiplying 1/2 by the 4/5 which was left in the refrigerator.

The question asks what fraction of the entire pumpkin pie Jeff ate on Saturday if he left 4/5 of it in the refrigerator and then ate 1/2 of what was left. To solve this, we'll calculate the fraction of the pie he consumed using multiplication.

He started with 4/5 of the pie left. Eating 1/2 of what was left means he consumed 1/2 of 4/5, which can be calculated as:

(1/2) times (4/5) = 4/10 = 2/5

Jeff ate 2/5 of the entire pumpkin pie on Saturday.

Answer: The width of each section is [tex]3\frac{2}{3}\ inches[/tex] .

Step-by-step explanation:

Since we have given that

Length of a page = 11 inches

According to question, Flyers are folded into thirds before being stapled and mailed.

So, Width of each section is given by

[tex]\frac{11}{3}\\\\=3\frac{2}{3}\ inches[/tex]

Hence, the width of each section is [tex]3\frac{2}{3}\ inches[/tex] .

To find the value of f(-7), substitute -7 into the function f(x) = 8x + 15. The value of f(-7) is -41.

To find the value of f(-7), we substitute -7 into the function f(x) = 8x + 15.

f(-7) = 8(-7) + 15 = -56 + 15 = -41.

Therefore, the value of f(-7) is -41.
