ill mark you brainliest pls help!
Answer choices:
A. 2ft
B. 4ft
C. 10ft
D. 14ft

Answers

Answer:

B. 4 ft

Step-by-step explanation:

First, find the width of the wall.

The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.

Use the pythagorean theorem and solve for a, the width of the wall.

a² + b² = c²

a² + 16² = 20²

a² + 256 = 400

a² = 144

a = 12

So, the width of the wall is 12 feet.

Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.

Use the pythagorean theorem again and solve for a, the width of the mural:

a² + b² = c²

a² + 6² = 10²

a² + 36 = 100

a² = 64

a = 8

So, the width of the mural is 8 feet.

Now, find the difference between the widths of the wall and mural:

12 - 8

= 4

So, the difference between the two widths is B. 4 ft

Answer is...B 4 ft....

3. The three angles of a triangle measure x°, y° and 46°. Which of the following statements must be true?

Answers

Answer:

y=180-x is correct and finally y+x=180-46 is also correct

Step-by-step explanation:

Since all triangles add up to 180 degrees(so y+x+46=180 degrees), it cannot be the first one. The second one is correct because of fact families. And the x+y=46 is also incorrect because x+y+46 is 180 not x+y=46.

the number of points in the first five games of the football season are listed below. what is the mean number of points scored?

Answers

^ You again? Quit being sus and answer the question here instead of elsewhere.

To find the mean, all you have to do is add each number and then divide by how many numbers you added.

So, 38 + 29 + 16 + 42 + 33 = 158. There were five numbers added, so the next step is to divide 158 by 5. That equals 31.6 as your answer.

The mean number of points scored is 31.6 from the  number of points in the first five games of the football season

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The number of points in the first five games of the football season are listed in table.

We have to find the mean number of points scored.

Mean we get by dividing sum of scores of 5 games and number of games played.

sum of scores of 5 games = 38+29+16+42+33

=158

Total number of games = 5

Mean = 158/5

=31.6

Hence,  the mean number of points scored is 31.6.

Simplify the ratio 22:4

Answers

Answer:

2:11

Step-by-step explanation:

Answer:

11 : 2

Step-by-step explanation:

We have the ratio 22:4 and we are asked to simplify it.

Ratios work like fractions, you need to divide both sides by the same number until you reach a number that cannot be divided equally both towards the numerator and denominator unless making it a decimal.

If so, we can divide both of the numbers in this ratio by 2 because they are divisible by that.

22 : 4

22 / 2

4 / 2

11

2

11 : 2

Since both numbers cannot be divided equally without ending in a decimal, therefore, the simplified ratio is 11 : 2

what is the measure of each angle in a pentagon if the lengths of all five sides are equal? A-180 B-120 C-108 D-60

Answers

Answer:
C (108)

Step-by-step explanation:

Angles in a pentagon must add up to 540 degrees.
All sides equal mean all angles are equal
so all you must do is divide 540 by 5, which gets you to 108.
You can use inverse operations to check the work
108 x 5 = 540
