Answer:

a)  ∠a = 72°

∠b = 108°

b) ∠[tex]x[/tex] = 56°

c) ∠m = 95°

Step-by-step explanation:

a) This shape is a regular polygon with 5 sides.

Therefore, sum of the interior angles = (5 - 2) x 180 = 540°

Therefore, ∠b = 540 ÷ 5 = 108°

∠a = 180 - 108 = 72°

b) The sum of the exterior angles of a polygon = 360°

Therefore, 55 + 63 + 52 + 44 + 90 + [tex]x[/tex] = 360

304 + [tex]x[/tex] = 360

[tex]x[/tex] = 360 - 304 = 56°

c) The sum of the exterior angles of a polygon = 360°

Therefore, 40 + 40 + 35 + 40 + 50 + 60 + m = 360

265 + m = 360

m = 360 - 265 = 95

Given equation:

Solve:

Answer is 140 m³.

Yes, you are correct on this.

Answer:

930 feet

Step-by-step explanation:

[tex]=310yards\\\\=310yards*3\\\\=930feet[/tex]

Note that to convert the yards into feet we must multiply the value by 3.

Answer:

930 feet

Step-by-step explanation:

There are 3 feet in 1 yard. It is given to you to convert 310 yards into feet. Since 3 feet = 1 yard, simply multiply 3 with the given yards to obtain the feets:

310 yards x (3 feet/1 yard) = 930 feet/310 yards.

930 feet is your answer.

x = the larger

y = the smaller

x+y = 180

x = 180 - y (eq 1)

x = 16 + 3y (eq 2)

substitution eq 1 to eq 2

[tex]\tt 180-y=16+3y\\\\164=4y\rightarrow y=41, then~x=180-41=139[/tex]

Answer:

  5.  x = 7

  6.  x = 13; YZ = 28

Step-by-step explanation:

It can help to start by writing the similarity statement for each figure. To do that, you can identify corresponding features, then work around the figure in a direction that maintains the correspondence of the vertices. Here the figures are dilated, and problem 5 has the figure rotated. Since there is no reflection involved, the corresponding vertices remain in clockwise order.

Once you have written the similarity statement, you can identify the values given for corresponding parts. Here, the values are all for side lengths (not angles). Corresponding sides will have their vertices in the same relative position in the similarity statement.

Working counterclockwise from the acute angle, we have ...

  KNML ~ PSRQ

Then corresponding sides are ...

  KN = 7x -9 . . . . PS = 60

  NM = not given . . . . SR = not given

  ML = 4x +4 . . . . RQ = 48

  LK = not given . . . . QP = not given

Now, you can write a proportion that involves corresponding sides. The main point here is to put corresponding parts in the same relative locations in the proportion. We can write this a couple of ways:

  KN/ML = PS/RQ   ⇔   (7x -9)/(4x +4) = 60/48

or

  KN/PS = ML/RQ   ⇔   (7x -9)/60 = (4x +4)/48

We note here that solution is generally easier if the variable is put in the numerator of the expression. We might choose the latter form for that reason. We might choose the first form because we know we can reduce the fraction 60/48 to 5/4, simplifying the problem a bit.

Using the second form of the proportion, we can solve it as follows:

  (7x -9)/60 = (4x +4)/48

  4(7x -9) = 5(4x +4) . . . . . . multiply by the LCM of 60 and 48, which is 240

  28x -36 = 20x +20 . . . . . eliminate parentheses

  8x = 56 . . . . . . . . . . . add 36-20x to both sides

  x = 7 . . . . . . . . . divide by 8

__

Counterclockwise from S, the similarity statement can be written ...

  ΔSYZ ~ ΔSRT

Corresponding parts are ...

  SY = not given . . . . SR = not given

  YZ = 2x +2 . . . . RT = 3x -7

  ZS = 40-5 = 35 . . . . TS = 40

A suitable proportion is ...

  (2x +2)/35 = (3x -7)/40

  8(2x +2) = 7(3x -7) . . . . . . . . multiply by 280

  16x +16 = 21x -49 . . . . . . eliminate parentheses

  65 = 5x . . . . . . . . . add 49-16x to both sides

  x = 13 . . . . . . . divide by 5

  YZ = 2x +2 = 2(13) +2

  YZ = 28

It's b} the monthly Internet service is $31. 75 3 (x minus 5. 50) = 111. 75

Solution:

Simplify the distributive property and solve.

The solution to the equation is 15.

Your required solution :

Let us solve this equation..!!

Firstly multiplying 2 by (x - 2)

⇒ 2 × (x - 2) = 26

⇒ 2x - 4 = 26

On transposing -4 to R.H.S. it would be positive,

⇒ 2x = 26 + 4

⇒ 2x = 30

On dividing 30 by 2 we gets,

⇒ x = 30/2

⇒ x = 15

Therefore, value of x is 15.

Step-by-step explanation:

Given that there are two numbers.

let them be, x and y

using the unknown numbers,

make x the subject:

Solve them simultaneously:

Then another number, x:

Average:

Let the two numbers be x and y

x+y = 36 -----(1)

x - y = = 9-----(2)

(1)+(2)

x +y = 36

x - y = 9

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

2x = 45

x = 45/2

Then y =?

x - y =9

45/2 - y =9

y = 45/2-9

y = (45-18)/2

y = 27/2

The two numbers are 45/2 and 27/2

Using it's concept, it is found that the probabilities are:

a. 0.7143 = 71.43% probability that is contains coffee or candy.

b. 0.4348 = 43.48% probability that it contains tea, given that it contain mugs.

c. 0.1558 = 15.58% probability it contains tea and cookies.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Item a:

There is a total of 20 + 13 + 10 + 12 + 10 + 12 = 77 baskets, of which 20 + 13 + 10 + 12 = 55 contain coffee or candy, hence:

[tex]p = \frac{55}{77} = 0.7143[/tex]

0.7143 = 71.43% probability that is contains coffee or candy.

Item b:

13 + 10 = 23 contain mugs, of which 10 contain tea, hence:

[tex]p = \frac{10}{23} = 0.4348[/tex]

0.4348 = 43.48% probability that it contains tea, given that it contain mugs.

Item c:

Out of the 77, 12 contain tea and cookies, hence:

[tex]p = \frac{12}{77} = 0.1558[/tex]

0.1558 = 15.58% probability it contains tea and cookies.

(x-3)(x-2)

= x^2-2x-3x+6

= x^2-5x+6

x(x-3)-3(x-2)

= x^2-3x-3x+6

x^2-6x+6

In order to write 4/6 as 2/3 we would break apart pieces and to write 4/6 as 8/12 we would combine pieces.

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator. The numerator is the number above. While the denominator is the number below.

In order to write 4/6 as 2/3 we have to express in its simplest form. This means that you have to divide 4/6 by 2. In order to write 4/6 as 8/23, multiply 4/6 by 2.
