The average daily cost of Aaron of driving his car to work is $5.1169.

Average cost is calculated by dividing the total cost by the total output quantity.

Miles for a round trip for 1 day = 10.5 miles

Since it is round trip, total miles for 1 day = 10.5 × 2 = 21 miles

Miles for a round trip for 22 days = 21 × 22 = 462 miles

Gallons for 15 miles = 1 gallon

Gallons for 1 mile = 1/15 gallons

Gallons for 462 miles = 30.8 gallons

Cost per gallon = $1.09

Cost for 30.8 gallons = 30.8 × 1.09 = $33.572

Payment for car parking = $79

Total cost per month = $33.572 + $79 = $112.572

Average daily cost = $112.572 / 22 = $5.1169

Answer:

D. m<y=120

Step-by-step explanation:

have a good day!

The formula for the slope (also known as the "rise over run" or "gradient") of a line when given the coordinates of two points is:

m = (y2 - y1) / (x2 - x1)

Where (x1, y1) and (x2, y2) are the coordinates of the two points, and m is the slope of the line.

Note that the coordinates must be in a Cartesian coordinate system, and the points must be distinct, otherwise, the denominator (x2 - x1) will be zero and the division by zero is not defined.

For example, if you have two points (2, 4) and (6, 8), you can use the slope formula to find the slope of the line:

m = (8-4) / (6-2) = 4/4 = 1

The slope of the line is 1

The inequality is x ≤ 5.09, where x is the number of outfits. Rashon can buy at most 5 outfits while staying within his budget.

To determine the number of biking outfits Rashon can buy while staying within his budget, you can set up an inequality using the information provided.

First, calculate the total cost of the reflectors and gloves:

3 reflectors × $10.78 + $32.64 = $38.34 + $32.64 = $71

Then, subtract the cost of the bicycle, reflectors, and gloves from Rashon's budget: $780 - $481.28 - $71 = $227.72

Now, you can use this remaining amount to determine the number of biking outfits Rashon can buy.

Let x be the number of outfits he can buy

You can set up an inequality as follows:

44.95x ≤ $227.72

Dividing both sides by 44.95:

x ≤ 5.09

However, since the number of outfits is an integer, he can only buy 5 outfits at most.

Two triangles are congruent if and only if they have the same shape and size.

What is triangle ?

A triangle in which it is having three sides , three angles and the sum of three angles is always 180 degrees.

So, there are several ways to find out if two triangles are congruent, so we will study the triangles above to find the answers:

Case a. (AAS - Angle, Angle, Side)

AAS stands for "angle, angle, side" and means that we have two triangles where we know two angles and the non-included side are equal. So, for the figure above it is true that:

∠B = ∠E

∠A = ∠D

Case b. We don't have any information about this case that allows us to get a conclusion about congruence. Recall that for congruent triangles you need to compare three elements two by two.

Case c. (SSS - Side, Side, Side)

SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. So, for the figure:

Case d.  We only have two equal elements, but it is necessary to have three elements for comparing them doing the comparison two by two. There is not enough information for getting a conclusion.

227 18-inch cubes can fit inside the rectangular prism.

You may calculate how many 18-inch cubes can fit within a rectangular prism by dividing the rectangular prism's overall volume by the volume of a single 18-inch cube.

A rectangular prism's volume can be calculated using the formula length x width x height. In this instance, the dimensions are 312 inches long, 212 inches wide, and 3 inches high. As a result, the rectangular prism has a volume of 1,326,720 cubic inches (312 x 212 x 3).

A single 18-inch cube has a volume of 18 x 18 x 18 = 5832 cubic inches.

We divide the volume of the rectangular prism by the volume of a single 18-inch cube to get the number of 18-inch cubes that can fit inside: 1,326,720 / 5832 = 227.

Therefore, the rectangular prism can accommodate 227 18-inch cubes.

Please take note that this is an estimate and that there will not be enough room in the prism to fit 227 cubes exactly.

The base value of a numeral system can be founded by counting the number of unique digits or symbols used in the system.

The base value of a numeral system can be determined by counting the number of unique digits or symbols used in the system. For example, in the base 10 numeral system, which is commonly used in everyday life, the base value is 10 because it uses the digits 0 through 9. In the base 2 numeral system, which is also known as binary, the base value is 2 because it only uses the digits 0 and 1.

Another way to find the base value is to look at the exponent of the highest power of the base in the numeral system. For example, in the number 42 in base 10, the highest power of 10 is 10¹, which is 10. Therefore, the base value is 10. Similarly, in the number 1010 in binary, the highest power of 2 is 2³, which is 8. Therefore, the base value is 2.

It's important to note that when working with different numeral systems, it is essential to know the base value in order to understand the value of the number being represented.

In Mathematics, the translation of a geometric figure to the left simply means subtracting a digit from the value on the x-coordinate (x-axis) of the pre-image of a function.

On the other hand, a geometric figure that is translated up simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image or parent function.

Mathematically, a horizontal translation to the left is modeled by this mathematical expression g(x) = f(x + N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.
