Help me, please! I'd really appreciate it.

Hi there!

The interior angles of a trapezoid always sum up to 360° because a trapezoid is a quadrilateral, so:

360° = (8x + 7)° + (5x + 18)° + (14x - 11)° + (10x + 13)°

Combine like terms:

360° = 37x + 27

Subtract both sides by 27:

333° = 37x

Divide both sides by 37:

x = 9°

Plug in this value of x into the expression for ∠B:

8(9) + 7 = 72 + 7 = 79°

Answer:

m∠B = 79°

Step-by-step explanation:

For A given Figure

m∠A = 14x - 11°

m∠B = 8x + 7°

m∠C = 5x + 18°

m∠D = 10x + 13°

Now, For Quadrilateral we know that the sum of all angle in Quadrilateral is 360°

So,

(14x - 11°) + (8x + 7°) + (5x + 18°) + (10x + 13°) = 360°

14x - 11° + 8x + 7° + 5x + 18° + 10x + 13° = 360°

Now, Combine Like Terms

i.e.,

14x - 11° + 8x + 7° + 5x + 18° + 10x + 13° = 360°

14x + 8x + 5x + 10x - 11° + 7° + 18° + 13° = 360°

37x + 27° = 360°

Now, Subtract 27 from both side

37x + 27° - 27° = 360° - 27°

37x = 333°

Now, Divide 37 from both side

37x/37° = 333°/37°

x = 9°

Here, put the value of x in m∠B

m∠B = 8x + 7° = 8(9) + 7° = 72° + 7° = 79°

Thus, m∠B = 79°

(14x - 11°) + (8x + 7°) + (5x + 18°) + (10x + 13°) = 360°

37x + 27° = 360°

37(9) + 27° = 360°

333° + 27° = 360°

360° = 360°

Hence, L.H.S = R.H.S

Answer:

10, 24, 26

Step-by-step explanation:

Answer:

You find the mean by adding all the numbers together then divide the sum of that by the amount of numbers there are. You find the median by looking at the middle number. You find the mode by looking at the most used number. You find the range by subtracting the highest and lowest numbers.

Step-by-step explanation:

say you have these numbers ( 8, 7, 17, 12, 0, 9, 11, 5, 8)

Mean:

8 + 7 + 12 + 17 + 0 + 9 + 11 + 5 + 8 = 77

77 ÷ 9 = 8.5

Median: 0

Mode: 8

Range: 17 - 0 = 17

Answer:

median is the middle number

but if the are two numbers in middle u add those two n divide by 2

range is the biggest number subtract lowest number

mean is total average divide by the number of data

mode is the number that appears many times

Answer:

Future Value= 18,478 people

Step-by-step explanation:

eGiving the following information:

Present value (PV)= 10,173

Growth rate (g)= 0.089 every 10 years

Number of periods (n)= 7

To calculate the population in 2020, we need to use the following formula:

FV= PV*(1 + g)^n

FV= 10,173*(1.089^7)

FV= 18,478 people

Answer:

The hypotenuse is 25 inches.

Step-by-step explanation:

This is a right triangle, so the Pythagorean Theorem applies.

I will assume you know about the Pythagorean Theorem, therefore I will not define it.

Here, I am solving for the hypotenuse.

[tex]a^2+b^2=c^2[/tex]

[tex]24^2+7^2=c^2[/tex]

[tex]576+49=c^2[/tex]

[tex]625 = c^2[/tex]

[tex]25=c[/tex]

Answer:

25

Step-by-step explanation:

To find the hypotenuse, you need to use a^2+b^2=c^2

Plugging the numbers in, the equation is

24^2+7^2=c^2

From here, you can just solve the equation, simplifying it equals

576+49=c^2

Add the two values

625=c^2

from here, you would square both sides to get c standing alone. This results in the equation finishing with the answer:

25=c

or flipping it around to make sence

c=25

Hope this helps! Have a good rest of your day!!!

Answer:

The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%. Since the question is referring to persons older than 25 years, we'll include all the data above 25 years.

So under 25-35 years old is 44 and under 35 years old is 40.

  44 + 40 = 84

  84 / 429 = 0.1958 or 19.58%

The probability of having a hemoglobin level above 11 is 35.66%. We would just get the ratio of 153 people who have hemoglobin level above 11 over the population of 429. 153 / 429 = 0.356643 or 35.66%

Being older than 25 years and having a hemoglobin level above 11 is not dependent on each other. Since the data is inversely proportional. The older the person gets, the lesser the number of people having hemoglobin level above 11 (A) 19.58%.

I hope this helps!

The solution is, The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Answer: B: 1/5

Step-by-step explanation: To find the probability of a students favorite class being history, we add all of the students to a sum. When added correctly, you should have a sum of 60 students. The next thing we do is create a fraction of the amount of students that enjoy history. This makes our answer 12/60. While this is correct, it makes any other possible calculations a bit more difficult so we must simplify it. To simplify you simply divide the fraction until you can no longer divide it with common factors. So I divided 60 by 12 to get 5. Knowing that this is one number, we would put 1 as a numerator and 5 as the denominator. This means our answer is 1/5 or B.

The equivalent expression for the algebra m(n+p) is mn + mp.

Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.

From the given information, we have:

=  m(n + p)

To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:
