26.52 x 90.7 step by step

Since the result is negative, we can say that the price of the vase decreased by 37.5%. Rounding to a whole number, the percent change is 38% (since a 37.5% decrease is approximately equal to a 38% decrease).

Percent (often symbolized as "%") is a way of expressing a fraction or a portion of something in terms of hundredths. It is used to describe the relationship between a part and a whole, with the whole being represented by 100%. Percentages are commonly used in many areas of life, such as finance, business, and statistics. They can be used to describe changes in values over time, to compare different quantities or amounts, or to express probabilities or frequencies.

Here,

The percent change in the price of the vase can be calculated using the formula:

percent change = (new price - old price) / old price x 100%

In this case, the old price of the vase was $80 and the new price is $50. Substituting these values into the formula, we get:

percent change = ($50 - $80) / $80 x 100%

percent change = -0.375 x 100%

percent change = -37.5%

Step-by-step explanation:

The incorrect statement is:

B. The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x < 6.

In the given statement, there is an error in the inequality. The correct statement should be:

The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6.

When solving the three-part inequality - 5x < 15x^2 < 3, we need to split it into two separate inequalities. The correct splitting should be:

- 5x < 15x^2 and 15x^2 < 3

Simplifying the first inequality:

- 5x < 15x^2

Dividing by x (assuming x ≠ 0), we need to reverse the inequality sign:

- 5 < 15x

Simplifying the second inequality:

15x^2 < 3

Dividing by 15, we get:

x^2 < 1/5

Taking the square root (assuming x ≥ 0), we have two cases:

x < 1/√5 and -x < 1/√5

Combining these inequalities, we get:

- 5 < 15x and x < 1/√5 and -x < 1/√5

Therefore, the correct statement is that the three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6, not - 6 ≤ 5 - x < 6 as stated in option B.

Answer:

x= −1/95

Step-by-step explanation:

1. Subtract 110x from both sides.

15x + 8 − 110x = 110x + 9 − 110x

−95x + 8 = 9

2. Subtract 8 from both sides;

−95x + 8 − 8 = 9 − 8

−95x = 1

3. Divide both sides by -95;

x= −1/95

The central angles for the categories with the numbers 40, 100, 50, and 50 are 60 degrees, 150 degrees, 75 degrees, and 75 degrees, respectively.

To calculate the central angles for each category based on the given numbers 40, 100, 50, and 50, we need to find the proportion of each value to the total sum of all the values. Let's proceed with the following steps:

Step 1: Calculate the total sum of the given numbers: 40 + 100 + 50 + 50 = 240.

Step 2: Find the proportion of each value by dividing it by the total sum and multiplying it by 360 (since a full circle has 360 degrees).

Central angle for the first category: (40/240) * 360 = 60 degrees.

Central angle for the second category: (100/240) * 360 = 150 degrees.

Central angle for the third category: (50/240) * 360 = 75 degrees.

Central angle for the fourth category: (50/240) * 360 = 75 degrees.

The central angles for each category based on the given numbers are 60 degrees, 150 degrees, 75 degrees, and 75 degrees, respectively.

These central angles represent the relative proportions of each category's spending in relation to the total spending. They can be used to create a pie chart or visualize the distribution of expenses in a circular graph.

Answer:

45 degrees

Step-by-step explanation:

The 4 angles of a quadrilateral will add to 360.

We know 1 of them (angle B) is 90 degrees.

We can set up an equation to solve the others.

2x+3x+x+90 = 360

Now solve for x.

Start by combining the x terms together.

6x+90 = 360

6x = 360-90

6x = 270

(6x/6) = 270/6

x = 45 degrees

Check back to see if that makes sense and if the equation equals 360 when x is 45:

2x+3x+x+90 = 360

2(45)+3(45)+45+90=360.

By factoring out the GCF from each problem are ab(2a - 3b), 5a(3a - 4a³ + 2b) and 2a²c³(7a³ + ac - 3c).

What is GCF?

GCF stands for Greatest Common Factor, which is the largest number or expression that divides two or more numbers or expressions without leaving any remainder.

4) To factor it out, we divide each term by the GCF, the GCF (Greatest Common Factor) of the given terms is "ab".

2a²b ÷ ab = 2a²b/ab = 2a

-3ab² ÷ ab = -3ab²/ab = -3b

Therefore, we can write:

2a²b - 3ab² = ab(2a - 3b)

So, the factored form of the expression 2a²b - 3ab² is ab(2a - 3b).

5) To factor out the GCF (Greatest Common Factor) from the given expression:

15a² - 20a⁴ + 10ab

First, we can look for the common factors of the coefficients (15, -20, and 10), and we find that they all have a common factor of 5. So, we can factor out 5 from all three terms:

5(3a² - 4a⁴ + 2ab)

Next, we can look for the common factors of the variables (a^2 and ab), and we find that they both have a common factor of a. So, we can factor out a from all three terms:

5a(3a - 4a³ + 2b)

Therefore, the fully factored form of the given expression is 5a(3a - 4a³ + 2b)

6) To factor out the GCF (Greatest Common Factor) from the given expression, we need to find the largest possible factor that divides each term of the expression. The terms in the given expression have common factors of a and c, and the highest power of a that appears in all the terms is a², while the highest power of c that appears in all the terms is c³. So, the GCF of the given expression is 2a²c³.

We can factor it out as follows:

14a⁵c³ + 2a³c³ -6a²c⁴ = 2a²c³(7a³ + ac - 3c)

Note that we factored out a positive GCF, even though the last term is negative, because the negative sign is part of the term, not the GCF.

The probability of buying 3 tires is 0.05 and the cumulative probability distribution table is created.

What is meant by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given,

     Percentage of people who buys 4 tires = 50%

      Percentage of people who buys 2 tires = 32%

      Percentage of people who buys less than 2 tires = 13%

    Percentage of people who buys none = 6%

a) Prob(X=0) = 0.06

    Prob(X=2)  = 0.32

   Prob(X=4)  = 0.50

 Prob(X < 2) = Prob(X=0) + prob(X=1) = 0.06+ prob(X=1)

   prob(X=1) =   Prob(X < 2) - 0.06  = 0.13 - 0.06 = 0.07

Therefore prob(X = 3) = 1 - ( 0.5+0.32+0.07+0.06) = 1 - 0.95 = 0.05 = 5%

b) Cumulative probability distribution is as given in the figure.

Therefore the probability of buying 3 tires is 0.05 and the cumulative probability distribution table is created.

AC is not equal to CE based on the angle bisector theorem. The answer is: C. NO, you cannot use the angle bisector theorem to determine that AC = CE.

According to the angle bisector theorem, when a line segment divides an angle of a triangle, the line segment also divides the opposite side but does so in such a way that the two segments are proportional to the other two sides of the triangle. However, the two segments are not congruent to each other.

In the diagram given below that shows the suspect, the police officer, and the 26th Street toward Cherry Street, the angle bisector divides the side opposite to the angle divided into AC and CE. Thus, their length cannot be ascertain to be congruent to each other, however, based on the angle bisector theorem, we can only prove that their length is proportional to the other two sides of the triangle.

Given the coordinates of mid point be (4,-10).

We are required to find the ordered pairs that the mid point is (4,-20).

Coordinates show positions of points or something else on a surface.

There are various combinations whose mid point is (4,-10).

First are (4,-20),(4,0).

Mid point =[(4+4)/2,(-20+0)/2]

=(4,-10)

Second are (4,0) , (4,-20)

Mid point=[(4+4)/2,(0-20)/2]

=(4,-10)

Third are (8,-20),(0,0)

Mid point=[(8+0)/2,(-20+0)/2]

The answer to the equation −0.22x + x − 0.33x is 0.11x.

The answer is 0.11x. To solve this, we can start by rearranging the terms of the equation. The equation can be written as:

−0.22x + x − 0.33x = −0.22 + 0.33x

We then subtract x from both sides of the equation, resulting in:

−0.22x − x = −0.22 + 0.33x − x

We then combine like terms on the left side of the equation, resulting in:

−1.22x = −0.55

Finally, we divide both sides of the equation by -1.22 to solve for x, resulting in:

x = 0.11
