For every day late, there is a $25 penalty. If the bill was paid 3 days late, write an expression to represent the total penalty fees after3 days late.

Answer: 27

Step-by-step explanation:

This is a proportion.

a = 5

b = 9

So A must equal 15. In order to get that we multiply by 3. Since we did that to A, we must also do it to B; that way we keep an equal proportion.

9 x 3 = 27

The equilibrium price is 12 and the equilibrium quantity is 400.

It should be noted that on order to fund equilibrium price and quantity, we've to equate the quantity supplied and demanded. This will be:

Qd = 1060 - 55p

Qs = -200 + 50p

Qd = Qs

1060 - 55p = -200 + 50p

Collect like terms

-55p - 50p = -200 - 1060

-105p = -1260

Divide

p = 1260 / 105

p = 12

The equilibrium price is 12

Equilibrium quantity = -200 + 50p

= -200 + 50(12)

= -200 + 600

= 400

Step-by-step explanation:

Using the concept of ratios, there is 15 more blue balls

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio.

The ratio of white to blue balls is 3:5

The number of white bulbs is 45

let's calculate the number of blue balls to determine the total number of balls.

3 + 5 = 8;

(3 / 8) * x = 45

3x = 45 * 8

3x = 360

x = 360 / 3

x = 120

The total number of balls is 120.

The number of blue balls ;

5/8 * 120 = 75

To change ratio to 1 : 3 in respect to white and blue balls;

1 + 3 = 4

The number of blue balls can be calculated as;

3 /4 * 120 = 90

The number of blue balls now is 90 balls

There will be 90 - 75 =  15 balls

There's 15 more blue balls

Step-by-step explanation:

the area of the triangle ABC is found by using the formula 1/2 * (base * height). Here, the base is 0 and the height is 1. Thus, the area of the triangle ABC = 0.5.

Let x = 0, y = 1 in 5x2y = 31

31 = 0

Thus, the point B is (0, 0).

The area of the triangle ABC = 1/2 * (0 * 1) + (0 * 1) + (1 * 0) = 0.5.

The equation of line L is given as 5x2y = 31. To find the point B, we need to substitute x = 0 in the equation. Doing so, we get 31 = 0, which means that the point B lies on the y-axis at (0, 0).

Next, since the line M is perpendicular to L and passes through A, we can assume that it is a horizontal line passing through (0, 1). Thus, the point C is the point of intersection of L and M, which is (1, 0).

Finally, the area of the triangle ABC is found by using the formula 1/2 * (base * height). Here, the base is 0 and the height is 1. Thus, the area of the triangle ABC = 0.5.

The logical statement [tex]$(a \wedge b) \rightarrow(b \vee c)$[/tex] is a tautology. Hence, Option B is the most appropriate answer to the given question.

A tautology is a logical statement where the conclusion is always equivalent to the premise. No matter what the individual parts are, the result is always a true statement; i.e. a tautology is always true. The opposite of tautology is either a contradiction or a fallacy.

a. let us check the first option.

[tex](a \vee b) \rightarrow(b \wedge c)=(a+b)^{\prime}+b c[/tex]

[tex](a \vee b) \rightarrow(b \wedge c)=a^{\prime} b^{\prime}+b c[/tex]

Therefore, [tex]$(a \vee b) \rightarrow(b \wedge c)$[/tex] is a contingency and not a tautology.

b. let us check the second option.

[tex](a \wedge b) \rightarrow(b \vee c)=a b \rightarrow b+c[/tex]

[tex](a \wedge b) \rightarrow(b \vee c)=(a b)^{\prime}+b+c[/tex]

[tex](a \wedge b) \rightarrow(b \vee c)=a^{\prime}+b^{\prime}+b+c[/tex]

[tex](a \wedge b) \rightarrow(b \vee c)=a^{\prime}+1+c[/tex]   (since, b' + b = 1)

[tex](a \wedge b) \rightarrow(b \vee c)=1.[/tex]

Therefore, [tex]$(a \wedge b) \rightarrow(b \vee c)$[/tex] is a tautology.

c. let us check the third option.

[tex](a \wedge b) \rightarrow(b \rightarrow c)=(a+b) \rightarrow\left(b^{\prime}+c\right)[/tex]

[tex](a \wedge b) \rightarrow(b \rightarrow c)=(a+b)^{\prime}+b^{\prime}+c[/tex]

[tex](a \wedge b) \rightarrow(b \rightarrow c)=a^{\prime} b^{\prime}+b^{\prime}+c[/tex]

[tex](a \wedge b) \rightarrow(b \rightarrow c)=b^{\prime}+c[/tex]

Therefore, [tex]$(a \wedge b) \rightarrow(b \rightarrow c)$[/tex] is contingency but not a tautology.

d. let us check the fourth option.

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=\left(a^{\prime}+b\right) \rightarrow\left(b^{\prime}+c\right)[/tex]

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=\left(a^{\prime}+b\right)+b^{\prime}+c[/tex]

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=a b^{\prime}+b^{\prime}+c[/tex]

[tex](a \rightarrow b) \rightarrow(b \rightarrow c)=b^{\prime}+c[/tex]

Therefore, [tex]$(a \rightarrow b) \rightarrow(b \rightarrow c)$[/tex] is contingency but not a tautology.

Hence, option B is the only example of tautology.

The equals sign (=) must appear in an equation. You can think of an equation as having a left and a right side since there will be a mathematical expression on either side of it. Consider an equation to be a set of scales. Although you can use different amounts on either side, for it to be solved, each side must be equally balanced. An unknown will always be present in an algebraic equation. This is symbolized by a symbol, such x, y, or z.

Here,

Given: Given: To reward her students for good behavior, Mrs. Morton fills a marble jar with three marbles.

if there are 24 marbles in the jar. When r denotes the quantity of additional rewards for the class, then the necessary equation is 24 + 3r 100.

If we can figure it out, we'll obtain the minimum number of marbles the jar holds—24.

In order to solve the problem, take 24 away from both sides.

Answer:

$51.20 is the cost after a 20% reduction.

Explanation:

There are two ways that this can be determined.

First, we can find what 20% of the original $64 price is and subtract the discount from the price.

20% = 0.20

0.20 ( $64) = $12.80

$64 - $12.80 = $51.20

Or

We can say that $64 is 100% of the price and subtract the 20% meaning the sale price will be 80% of the original price.

100% = 1.00 20% = .20

$64(1.00-.20) = $64(.80) = $51.20

The probability that two or more of the events will occur is 0.683594.

The probability that two or more of the events will occur is equal to 1 minus the probability that none of the events will occur. Since the probability of each event occurring is 0.25, the probability that none of the events will occur is (1 - 0.25) * (1 - 0.25) * (1 - 0.25) * (1 - 0.25) = 0.316406. Therefore, the probability that two or more of the events will occur is 1 - 0.316406 = 0.683594.

Alternatively, you can find the probability that two or more of the events will occur by adding up the probabilities of each of the ways that two or more of the events can occur.

There are four ways that two events can occur (for example, event A and event B), six ways that three events can occur (for example, event A, event B, and event C), and four ways that all four events can occur.

Thus, the probability that two or more of the events will occur is (4 * 0.25 * 0.25) + (6 * 0.25 * 0.25 * 0.25) + (4 * 0.25 * 0.25 * 0.25 * 0.25) = 0.683594, which is the same result as before.

yes, that's really it.

it just means that any value is valid for y.

this line is not a function, because the one valid value for x (3) has infinitely many assigned y values.

10.

the usual equation for a line is

y = ax + b

with "a" being the slope, "b" being the y-intercept (the y-value when x = 0).

we see that b = 0, as the line goes through the origin (0, 0).

the slope is the ratio

y coordinate difference / x coordinate difference

when going from one point on the line to another.

we see e.g. the points (0, 0) and (1, -3). I always recommend to look for points with integer coordinates.

when going from one to the other,

x changes by +1 (from 0 to 1).

y changes by -3 (from 0 to -3).

the slope "a" = -3/1 = -3.

The horizontal component of the force vector is 260 pounds, and the vertical component is 150 pounds. (Option B).

To find the horizontal and vertical components of the force vector, we can use trigonometry. The horizontal component is the force acting in the direction parallel to the ground (x-axis), and the vertical component is the force acting in the direction perpendicular to the ground (y-axis).

Given that the force is 300 pounds and makes a 30° angle with the ground, we can calculate the components as follows:

Horizontal component (F_horizontal) = Force * cos(angle)

Vertical component (F_vertical) = Force * sin(angle)

Inserting in the values:

Horizontal component (F_horizontal) = 300 pounds * cos(30°)

Vertical component (F_vertical) = 300 pounds * sin(30°)

Now, let's calculate:

Horizontal component (F_horizontal) = 300 pounds * 0.866 (rounded to 3 decimal places, cos(30°) ≈ 0.866)

F_horizontal ≈ 259.8 pounds

Vertical component (F_vertical) = 300 pounds * 0.5 (rounded to 3 decimal places, sin(30°) ≈ 0.5)

F_vertical ≈ 150 pounds

Therefore, the required components of the force vector are approximately 260 pounds and 150 pounds.
