A cab company charges a $11 boarding fee and a meter rate of $2 per mile. The equation is y = 2x + 11 where x represents the number of miles to your destination. If you traveled 5 miles to your destination, how much would your total cab fee be?
We are given a function, y = 2x + 11, where x is the number of miles driven. If we are told that the cab was driven 5 miles, x = 5. So, substitute 5 for x.
y = 2x + 11
= 2(5) + 11
= 10 + 11
= 21
y = 21
The survey results of the towns favorite holiday were displayed in a newspaper as described37% of people enjoy Fourth of July•28% of people enjoy New Years Eve42% of people enjoy Memorial DayC5% of people enjoy all three12 % of people enjoy New Years Eve and Memorial Day•18 % of people enjoy Fourth of July and New Years Eve13% of people enjoy Memorial Day onlyWhat percentage of people enjoy New Years Eve only?
In order to calculate the percentage that enjoy New Years Eve only, we can use the diagram and formula below:
Using F to represent Fourth of July, N to represent New Years Eve and M to represent Memorial Day, the formula is:
[tex]P(N\text{ only})=P(N)-P(F\text{ and }N)-P(M\text{ and }N)+P(all\text{ }three)[/tex]From the given data, we have:
P(N) = 28% = 0.28
P(F and N) = 18% = 0.18
P(M and N) = 12% = 0.12
P(all three) = 5% = 0.05
So P(N only) is:
[tex]\begin{gathered} P(N\text{ only})=0.28-0.18-0.12+0.05\\ \\ P(N\text{ only})=0.03=3\% \end{gathered}[/tex]Identify the theorem or postulate that is related to the measures of the angles in the pair, and find the unknown angle measures.
m/1 = (5x +15)°, m/4= (30x - 60)°
To identify the answer we will use Angles Theorem which is m∠1 = 150. When the transversal line cuts through the two parallel lines, it creates the alternate exterior angles 1 and 8. Both are consistent with the alternate exterior angles theorem. As a result, m1 = m8 and m1 = (50x)°.
m∠8 = 150
Setting both equal, find x 50x = 150.
50x/50 = 150/50 x = 3 when you divide both sides by 50.
Unknown stance
m∠1 = (50x) = 50*3 = 150°
What exactly is a mathematical postulate?A proposition—also referred to as an axiom—that is accepted as true without evidence. Lemmas and theorems arise from postulates, which is their fundamental structure. Five tenets, referred to as Euclid's postulates, form the foundation of Euclidean geometry as a whole.
An unsupported assertion is referred to as a postulate. A postulate is also referred to as an axiom. For instance, you would believe Pam if she claimed that all of her siblings are at least five foot one tall if you knew that she is five feet tall and that all of her siblings are taller than her.
The fundamental tenet of consumer theory holds that consumers choose the bundle from the available options that provides the greatest level of satisfaction. On the set of bundles, assumptions are made that ensure the existence of a comprehensive, reflexive, and transitive preference order.

The value of the height of the rectangle is 80 m.
Rectangles
The rectangle is a quadrilateral. The classification for quadrilaterals is given by the length of sides and angles. For a rectangle, the opposite sides are equal and parallel and their interior angles are equal to 90°.
A rectangle is a geometric figure that has 4 sides called: length and height. Due to its characteristics, the rectangle presents two length (L) and two heights (H).
The perimeter is the sum of all sides of a geometric figures. For a rectangle, the perimeter is 2L+2H.
The question gives:
length (base) = 20 + H width (height) = H perimeter = 360 mFrom the perimeter, you can find the height, see below.
P=2L+2H
360=2*(20 + H) +2H
360= 40 +2H +2H
360-40 = 4H
320= 4H
320/4 = H

Find the difference or type
"impossible"
[3 –8] + [4 - 5 -6]
? ? ?
It’s a matrice
The difference of the two matrices [3 -8] and [4 -5 -6] is an impossible operation to execute as per arithmetic rules.
As per the question statement, we are provided with two matrices, [3 -8] and [4 -5 -6].
We are either required to calculate the difference of the above mentioned matrices, or else, determine if the operation is impossible to perform.
To solve this question, we need to know about the order of a matrix first.
The Order of a matrix is the representation of the number of rows and columns of that matrix, in the form of "m×n" and read as (m by n), where "m" is the number of rows in that matrix while "n" is the number of columns. It also tells us about the total number of entries or elements in a particular matrix, which we can calculate by performing the multiplication of it's order, i.e., (m * n)Now, one basic rule of matrix subtraction is that, matrices having the same order can only be subtracted from each other.Here, in our case, matrix [3 -8] is of the order (1×2) while matrix [4 -5 -6] is of the order (1×3), i.e., the orders of our concerned matrices are not same.
Hence, as per the above mentioned rule, we cannot execute the difference of [3 -8] and [4 -5 -6], and yes, it is an impossible task.

Explain what it means to solve a formula for a variable
The meaning of solving a formula for a variable is rewriting the formula in a way that the variable is "isolated" in one side of the formula, that is, one side of the equation has only the variable alone, without coefficients or other expressions.
For example, let's solve the formula below for the variable y:
[tex]\begin{gathered} 2x+3y+4=0\\ \\ 3y=-2x-4\\ \\ y=\frac{-2x-4}{3} \end{gathered}[/tex]We can see that in the formula above, the left side of the equation has only "y", this way it is solved for y.

For the parallelogram, AB = 12 and BD = 20. Find the length of AC.АThe length of the diagonal AC isBE
The value of line segment AB is given in the problem. Line segment AB is half of the diagonal AC. Hence, if we want to solve for the length of the diagonal AC, we just multiply the length of line segment AB by 2. This is a parallelogram, therefore, we can say that the line segment AB is half of the diagonal AC.
The length of the diagonal AC is therefore 12 x 2 = 24.

EXPLANATION:
(5x - 6.9)(2x + 12.2)
Let's open the bracket by multiplying:

Let's collect like terms but adding and subtracting each variable according to its power:
10x² + 47.2x - 82.18
Therefore, the simplified form of (5x-6.9)(2x + 12.2) is 10x² + 47.2x - 82.18.
So, the correct option is the second option which is 10x² + 47.2x - 82.18.
