Answer:

3240°

Explanation:

The formula for calculating the sum of the interior angles of a polygon is (n-2)x180 where n refers to the number of sides. Because we know that the polygon has 20 sides, the equation would be (20-2)x180. The answer would be 3240°.

Answer:135

Step-by-step explanation:72 + 63 =135

Answer:

Volume = 11680.44 cubic inches

Step-by-step explanation:

Circumference of the trunk of a tree = 2πr

Here, r = radius of the trunk

26π = 2πr

r = 13 inch

Since, volume of the cylindrical trunk = πr²h

= π(13)²(22)

= 3718π

= 11680.44 cubic inches

Answer:

P = 48°

Step-by-step explanation:

Its an isosceles triangle so angle M and angle N are the same since they are the opposite angles to the sides that have the same measurement. so it would

180 - (66)2 = angle P

Sorry if you dont understand what i mean

Answer:

8(2+a) is the answer that you need there really is not much thought to it

Answer: I believe its B

Step-by-step explanation:

Answer:

Step-by-step explanation:

The sum of interior angles is 180(n-2) where n=number of sides. In this case there are 8 sides so the sum of angles is

180(8-2)=1080 degrees. Now can solve for x

5x+4x+138+116+132+126+134+123=1080

9x+769=1080

9x=311

x=34.6

Answer:

Both expressions equals to 32.

Step-by-step explanation:

You just plug in 5 for each expression: 12+4(5)=32, 4(5+3)=32.

Answer:

1) f = 16

2) h = 10

Step-by-step explanation:

all interior angles of a triangle add up to 180 degrees.

1) 46 + 67 + (4f+3) = 180

reduce:

4f+3 = 67

4f = 64

f = 16

2) 60 + 3h + 90 = 180

3h = 30

h = 10

Answer:

y = -2x + 3

Step-by-step explanation:

y = mx + b

slope = m

m = y2 - y1/x2 - x1

-3 - 3/3 - 0 = -6/3

m = -2

y = -2x + b

b = y-intercept

b = 3

y = -2x + 3

Slope = -2

y intercept = 3

==========================================================

Explanation:

Use the two points shown in the slope formula

m = (y2-y1)/(x2-x1)

m = (-3-3)/(3-0)

m = -6/3

m = -2

The slope of -2 can be thought of as -2/1

slope = -2/1 = rise/run

rise = -2 and run = 1

Each time we move down 2 units, we move to the right 1 unit.

The y intercept is b = 3 since this is the location where the line crosses the y axis.

We go from y = mx+b to y = -2x+3 as the final answer

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

To check the answer, let's plug in (x,y) = (0,3)

y = -2x+3

3 = -2(0)+3 ... replace x with 0 and y with 3

3 = 0+3

3 = 3 ... true equation

Now let's plug in (x,y) = (3,-3)

y = -2x+3

-3 = -2(3)+3 ... plug in x = 3 and y = -3

-3 = -6+3

-3 = -3 .... also true

Because both points make the equation y = -2x+3 true, this confirms we have the correct equation.

Answer:

I think it's obtuse please don't come at me if I'm wrong.

it would be a right triangle because there’s a corner. obtuse and acute triangles have points.

Answer:

perimeter = 26 m

for area ,divide figure in two parts

area = area of 1st part = 8 m^2

area of 2nd part = 7m^2

area of whole figure = 15m^2

Answer:

22.4

Step-by-step explanation:

using altitude theorem, the height of the triangle is 20

let y = height

10/y = y/40

y² = 400

y = [tex]\sqrt{400}[/tex] or 20

Now we can us the Pythagorean Theorem to find 'x':

10² + 20² = x²

100 + 400 = x²

x=[tex]\sqrt{500}[/tex] ≈ 22.4

Answer:

Diameter is C. 10.8

Circumference in terms of Pi is C. 10.8(pi)

Circumference is D. 33.9

Step-by-step explanation:

radius x 2= diameter

5.5x2=10.8

C=2(pi)r

C=2(pi)5.4

C=10.8(pi)

C=2(pi)r

C=2(3.14)5.4

C=33.9

Answer:

Number 1 is 10.8

Number 2 is 10.8

Number 3 is 33.9

Step-by-step explanation:

7/11 x 99 = 63

4/11 x 99 = 36

63-36 = 27

Answer:

27

Step-by-step explanation:

7/11 * 9/9 = 63/99

4/11 * 9/9 = 36/99

63-36 =27

Answer:

20 and 25

Answer:

Step-by-step explanation:

j=d-27

d=2j-2, using j from above makes this equation become

d=2(d-27)-2

d=2d-54-2

d=2d-56

-d=-56

d=56, since j=d-27

j=56-27

j=29

So John is 29 and Dre is 56

Third: then you'll get z<8

Answer: 10.5

Step-by-step explanation:

Answer:

10.5 cm

Step-by-step explanation:

First, the unit rate is .375 cm, because 3/8 = .375, so to find your answer you need to do .375 x 28 which = 10.5 cm.

Hope this helps!

Answer:

11/8 or 1 3/8

Step-by-step explanation:

first you have to change the denominator to 8 in the 3/4, so that means you have to change the numerator too.

that gets you 6/8, so the new equation is

6/8+5/8

you only have to add the numerators, so it gives you 11/8.

to change it to a mixed number, all you have to do is find how many whole numbers (aka 8/8 in this situation) go into your improper fraction, and there is 1 in ours. you set that aside and you get 3/8 left over. You put those together and get 1 3/8

hope this helps! have a nice day!

Answer:

C

Step-by-step explanation:

I think,  :)

The boxplot below displays the arm spans for 44 student . The statement that is not true from the given option is

Approximately 25% of the arm spans are less than 180 cm

Option C

Given :

The boxplot below displays the arm spans for 44 students.

The five-number summary for the data is 143, 162, 168, 180, and 202.

From the given five number summary we can see that

minimum =143

First Quartile (25%)= 162

Median (50%)= 168

Third quartile (75%)= 180

Maximum =202

Now we analyze the statements

Approximately 75% of the arm spans are less than 180 cm. Its true because third quartile is 75% that is equal to 180

Approximately 50% of the arm spans are less than 168 cm.. Yes its true because median is 168

Approximately 25% of the arm spans are less than 180 cm. It is false because first quartile 25% is 162. So , 25% of the arm spans are less than 162 cm

Approximately 75% of the arm spans are greater than 162 cm. It is true . because  25% of the arm spans are less than 162 cm
