Answer 1

Answer:

15. ∠ABE = 50°

16. ∠EBD = 10n - 19

Step-by-step explanation:

If [tex]$ \overline{\textbf{BE}} $[/tex] bisects ∠ABD then we have ∠ABE = ∠DBE

So, we will have: (6x + 2)° = (8x - 14)°

⇒ 6x + 2 = 8x - 14

⇒ 8x - 6x = 14 + 2

⇒ 2x =16

x = 8

∴ ∠ABE = 6(8) + 2

= 48 + 2

= 50°

∴∠ABE = 50°

16. If [tex]$ \overline{\textbf{BE}} $[/tex] bisects ∠ABD then ∠ABE + ∠EBD = ∠ABD

⇒(12n - 8) + ∠EBD = (22n - 11)

⇒ ∠EBD = 22n - 11 - 12n + 8

∠EBD = 10n - 3

Hence, the answer.

Calculate the slope between the following points (1,6) (3,-7)

Answers

Answer:

-13/2

Step-by-step explanation:

slope is calculated as (y2-y1)/(x2-x1)

(x1, x2) is (1,6) and (y1,y2) is (3,-7)

doing (y2-y1)/(x2-x1) gives us ((-7)-6)/(3-1)

= -13/2

Final answer:

The slope between the points (1,6) and (3,-7) is calculated as -6.5 using the slope formula.

Explanation:

The slope between two points (1,6) and (3,-7) can be calculated using the slope formula: m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of the points.

In this case, substituting the values in, we get:

m = (-7 - 6) / (3 - 1) = -13 / 2 = -6.5.

Thus, the slope between the points (1,6) and (3,-7) is -6.5.

PLEASE ANSWER I NEED HELP!!! ​

Answers

The correct answer is E. Both functions are linear, only crossing the x-axis once and the y-axis once.

We can see from the graph that both Function A and Function B are straight lines. This means they are linear functions.

Linear functions also have only one x-intercept and one y-intercept. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

The y-intercept for both Function A and Function B is at (0,0). The x-intercept for Function A is at (-2,0) and the x-intercept for Function B is at (1,0).

Therefore, both statements in choice E are true.

The other statements in the question are not true.

Choice A, Both functions have negative rates of change, is not true. Function A has a negative rate of change, but Function B has a positive rate of change.

Choice B, Both functions have the same rate of change, is not true, as discussed above.

Choice C, When graphed, Function A and Function B are parallel, is not true. Parallel lines would never intersect, but the two functions intersect at the origin.

Choice D, Function A has a greater rate of change than Function B, is not true. The slope of Function B is steeper than the slope of Function A, so Function B has a greater rate of change.

The height of a building on a 1/4 inch: 1 foot scale drawing is five inches tall. How tall is the actual building?

Answers

Answer:

The height of the building is [tex]1\frac{1}{4}\ feet.[/tex]

Step-by-step explanation:

Given:

Scale drawing is 1/4 inch: 1 foot.

The height of the building in drawing is 5 inches.

Now, to find the actual height of the building.

Let the actual height be [tex]x.[/tex]

The height of the building in drawing = [tex]5\ inches.[/tex]

The ratio of the scale drawing is [tex]\frac{1}{4}\ inch:1\ foot.[/tex]

So, [tex]\frac{1}{4}\ inch[/tex] is equivalent is 1 foot.

Thus, 5 inches is equivalent to [tex]x.[/tex]

Now, to get the actual height of the building by using cross multiplication method:

[tex]\frac{\frac{1}{4}}{1} =\frac{5}{x}[/tex]

[tex]\frac{4}{1} =\frac{5}{x}[/tex]

By cross multiplying we get:

[tex]4x=5[/tex]

Dividing both sides by 4 we get:

[tex]x=\frac{5}{4}[/tex]

[tex]x=1\frac{1}{4}[/tex]

Therefore, the height of the building is [tex]1\frac{1}{4}\ feet.[/tex]

Solve for x: 2x ^ 3 - x ^ 2 + 18x - 9 = 0

Answers

Answer:

see explanation

Step-by-step explanation:

Given

2x³ - x² + 18x - 9 = 0 ( factor the first/second and third/fourth terms )

x²(2x - 1) + 9(2x - 1) = 0 ← factor out (2x - 1) from each term

(2x - 1)(x² + 9) = 0

Equate each factor to zero and solve for x

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

x² + 9 = 0 ⇒ x² = - 9 ⇒ x = ± 3i

The equation has 1 real solution and 2 complex solutions

assuming that each salesperson earned commission on all items he or she sold who earned the most commission​

Answers

Answer:

ITS RUTH

Step-by-step explanation:

Final answer:

To know who earned the most commission, one must multiply the number of items sold by each salesperson by their respective commission rates. The one with the highest total is the salesperson who earned the most commission.

Explanation:

To determine who earned the most commission, you first need to have concrete data. This should include the number of items each salesperson sold and the commission rate or amount associated with each item.

Multiply the number of items each person sold by the respective commission to get the total commission earned by each salesperson.

The salesperson with the highest total commission is the one who earned the most. For instance, if salesperson A sold 50 items with a commission of $2 per item, their total commission would be 50*2 = $100.

If salesperson B sold 30 items at $5 per item, their total would be 150.

Hence, in this situation salesperson B earned more commission even though they sold fewer items.

Assuming a person from this survey is selected at random, what is the probability that a person perfers rap music given that the person is female?​

Answers

Answer:

The probabiliy of selecting a person who prefeers rap if the person is female an be calculated as the proportion of women who prefeer rap music: 23.6%.

Step-by-step explanation:

The total amount of persons in the survey is 200:  women in the sample equal to 106 ( 54 of them preferred techno music, 45 of them prefeer rap and 27 of them prefeer country music), while there are 94 men in the sample (36 of them preferred techno music, 40 of them prefeer rap and 18 of them prefeer country music).The probabiliy of selecting a person who prefeers rap if the person is female can be calculated as the proportion of women who prefeer rap music: [tex]\frac{25}{106}=23.6\%[/tex]. Knowing that the person is a female gives you information, you are no longer looking at the 200 person survey, you are interest in a part of it: the women participants. Then, conditional on knowing that the person is a women (then, we are looking at the 106 cases in which the persons of the survey are women), we now find the probability of finding women who prefeer rap music: 25 between 106 cases, which is [tex]23.6\%[/tex] .

jason went to the post office and bought both 41 cent stamps and 26 cent postcards and spent $20.28. The number of stamps was 4 more than twice the number of post cards. How many of each did he buy?

Answers

Jason bought 38 stamps and 17 postcards

Solution:

Let "a" be the number of stamps bought

Let "b" be the number of postcards bought

The number of stamps was 4 more than twice the number of post cards

Therefore,

Number of stamps bought = 4 + 2(number of post cards)

a = 4 + 2b ------- eqn 1

Jason bought both 41 cent stamps and 26 cent postcards and spent $20.28

1 dollar is equal to 100 cents

Thus, $ 20.28 is equal to 2028 cents

Therefore, we frame a equation as:

[tex]41 \times a + 26 \times b = 2028[/tex]

41a + 26b = 2028 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 1

41(4 + 2b) + 26b = 2028

164 + 82b + 26b = 2028

164 + 108b = 2028

108b = 1864

[tex]b = 17.25 \approx 17[/tex]

Substitute b = 17 in eqn 1

a = 4 + 2(17)

a = 4 + 34

a = 38

Thus Jason bought 38 stamps and 17 postcards

if carlos did some work and got 3x + 2x - 6 = 24 what mistake did he make

Answers

Carlos made the mistake that he did not combine like terms (3 x and 2 x) properly and did not use addition property of equality.

Step-by-step explanation:

Carlos did the work as 3 x + 2 x - 6 = 24

We need to find his mistake that he made in above given.

Here, he did not add the like terms (3 x and 2 x)

             3 x + 2 x = 5 x

Therefore, his work should be

             5 x  - 6 = 24

Also, he did not use addition property of equality. It means the equation remains same even though the same number gets added on both sides. It would be

                          5 x  - 6 = 24

                                 + 6 = + 6

                          -----------------------

                           5 x = 30

Dividing 30 by 5, we get answer as '6'. Hence,

                            [tex]x=\frac{30}{5}[/tex] = 6

So, stated the above two are the mistakes found in carlos work.

What is 4 and 16/25 simplified

Answers

Answer:

4.64

Step-by-step explanation:

To simplify mixed numbers you can write them either as a fraction or as a decimal number.

Fraction:

first we need to express both parts of mixed number through the same denominator - 1 has 25/25, so that means 4 has 100/25.

Now we can write that as 100/25 and 16/25, which is (100+16)/25 = 116/25

Decimal number:

This time, we convert this fraction part of a number to decimal. Simply dividing, we get that 16/25 equals 0.64. So 4 and 0.64 is 4.64.

Use the properties of operations to determine if each pair of expressions is equivalent for 1/2(4 - 2x); 2 - 2x

Answers

Answer:

They are not equivalent

Step-by-step explanation:

We want to determine if 1/2(4 - 2x); 2 - 2x are equivalent.

Let us take the first expression and simplify to see if we can get the second expression.

[tex] \frac{1}{2}(4 - 2x)[/tex]

Let us expand using the distributive property to get:

[tex] \frac{1}{2} (4 - 2x) = \frac{1}{2} \times 4 - \frac{1}{2} \times 2x[/tex]

This simplifies to:

[tex]\frac{1}{2} (4 - 2x) = 2 - x[/tex]

Therefore 1/2(4 - 2x); and 2 - 2x are not equivalent

is searching online for airline tickets. Two weeks​ ago, the cost to fly from Orlando to Denver was ​$250. Now the cost is ​$365. What is the percent​ increase? What would be the percent increase if the airline charges an additional​ $50 baggage fee with the new ticket​ price?

Answers

Percent increase without baggage = 46%

Percent increase with baggage = 66%

Step-by-step explanation:

Cost of ticket two weeks ago= Old value = $250

Increased cost = New value = $365

Change = New value - Old value

Change = 365 - 250 = $115

Percent increase = [tex]\frac{Change}{Old\ value}*100[/tex]

Percent increase = [tex]\frac{115}{250}*100[/tex]

Percent increase = [tex]\frac{11500}{250}=46\%[/tex]

There is 46% increase in the price.

Change after additional baggage = 115+50 = $165

Percent increase = [tex]\frac{165}{250}*100[/tex]

Percent increase = [tex]\frac{16500}{250}=66\%[/tex]

Percent increase without baggage = 46%

Percent increase with baggage = 66%

#LearnwithBrainly

Final answer:

The percent increase in the cost of airline tickets from Orlando to Denver is 46%. If an additional $50 baggage fee is charged, the percent increase is 66%.

Explanation:

To calculate the percent increase, we can use the formula: Percent Increase = ((New Value - Old Value) / Old Value) x 100. In this case, the old value is $250 and the new value is $365. Therefore, the percent increase is ((365 - 250) / 250) x 100 = 46%.

If the airline charges an additional $50 baggage fee, the new ticket price would be $365 + $50 = $415. To calculate the percent increase from the original price, we can use the same formula. The old value is still $250 and the new value is $415. Therefore, the percent increase with the added baggage fee is ((415 - 250) / 250) x 100 = 66%.
