A quadrilateral has two angles that measure 135º and 120°. The other two angles are in a
ratio of 3:4. What are the measures of those two angles?

Answer:

90 cm, 180 cm, 240 cm

Step-by-step explanation:

Let the lengths of sides of the triangle be 3x, 6x and 8x

[tex] \therefore \: 3x + 6x + 8x = 5.1 \: m \\ \therefore \: 17x = 510 \: cm \\ \therefore \: x = \frac{510}{17} \\ \therefore \:x = 30 \: cm \\ \implies \\ 3x = 3 \times 30 = 90 \: cm \\ 6x = 6 \times 30 = 180 \: cm \\ 8x = 8 \times 30 = 240 \: cm[/tex]

Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.

Step-by-step explanation:

The median is 29

There is no mode

The mean is when you add them together will be 387 and then you divide it by 8 which will be equal to 48.375

The range will be 80 I don’t know if this is right

Answer:

B) 53%

Step-by-step explanation:

To find the percent divide the number who will vote for Candidate A over the total number of people surveyed

vote for Candidate A/total surveyed

128/240=0.53333

0.53333*100=53.3333%

Rounded to the nearest percent=53%

Answer:

x

Step-by-step explanation:

Sin A= 1-x² is the correct answer.

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here, Sin C = x/1 and therefore Hypotenuse = 1 and perpendicular =x

thus Base=1-x² by phytogaraen theorem.

Thus Sin A=1-x² /1

Hence, Sin A= 1-x² is the correct answer.

Here is what I got. I used the website called desmos. I hope this helped,.,

Answer:

Yes

Step-by-step explanation:

Start with the 2(x-y) and distribute the 2 to each term

2(x)-2(y)

This would equal

2x-2y

Which matches the second equation making the answer yes.

The pairs of expressions that are equivalent are:

- [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]

- [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]

- [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]

Let's simplify each expression to see if they are equivalent.

Step 1

1. [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]:

  Simplifying [tex]\( 2(x-y) \)[/tex]:

 [tex]\[ 2(x-y) = 2x - 2y \][/tex]

  Yes, they are equivalent.

Step 2

2. [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]:

  Simplifying [tex]\( 4(x+y) \):[/tex]

 [tex]\[ 4(x+y) = 4x + 4y \][/tex]

  Yes, they are equivalent.

Step 3

3. [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]:

  Simplifying  [tex]\( (3q-p)(7) \)[/tex]:

[tex]\[ (3q-p)(7) = 21q - 7p \][/tex]

  Yes, they are equivalent.

Step 4

4. [tex]\( 4(2a-3v) \)[/tex] and [tex]\( 8a+6v \)[/tex]:

  Simplifying [tex]\( 4(2a-3v) \)[/tex]:

 [tex]\[ 4(2a-3v) = 8a - 12v \][/tex]

  No, they are not equivalent.

Step 5

5. [tex]\( 8(3x+c)-1 \)[/tex] and [tex]\( 8c+24x-1 \)[/tex]:

  Simplifying [tex]\( 8(3x+c)-1 \)[/tex]:

  [tex]\[ 8(3x+c)-1 = 24x + 8c - 1 \][/tex]

  No, they are not equivalent.

Step 6

6. [tex]\( 4p+3c \)[/tex] and [tex]\( (c+2p)(2) \)[/tex]:

  Simplifying [tex]\( (c+2p)(2) \)[/tex]:

[tex]\[ (c+2p)(2) = 2c + 4p \][/tex]

  No, they are not equivalent.

[tex]\( (3q-p)(7) \)[/tex]

Step-by-step explanation:

3(3y-4)=33

9y-12=33

9y=45

y=5

Answer:

y = 5

Step-by-step explanation:

First you need to distribute.

3(3y - 4) = 33

9y - 12 = 33

Then add 12 to both sides.

9y = 45

Now, divide both sides by 9.

Y = 5

[tex]14\frac{17}{20}[/tex]

Step-by-step explanation:

[tex]6\frac{3}{5} (2\frac{1}{4})\\\\\frac{33}{5} (\frac{9}{4} )\\\\\frac{297}{20} = 14\frac{17}{20}[/tex]

Answer:

14  17/20

Step-by-step explanation:

Convert the mixed numbers to improper fractions first.

So 6 3/5 =33/5  and 2 1/4 =9/4

Then multiply 33/5 x 9/4

33 x 9=297  

5 x 4 =20

Then convert 297/20 back to a mixed number by dividing

14 x20 =280

you have 17/20 left

Answer:

Step-by-step explanation:

a) X + 5 = 11

   Subtract 5 from both sides

   X = 6

b) X - 6 = 8

   Add 6 on both sides

   X = 14

c) 3 + X = 7

   Subtract 3 on both sides

   X = 4

d) 12 = X + 5

   Subtract 5 from both sides

    7 = X or X = 7

Answer:

a) x=6

subtract 5 from each side.

b) x= 14

add 6 to each side

c) x=4

subtract 3 from both sides

d) x=7

subtract 5 from both sides

Step-by-step explanation:

a) subtract 5 from each side.

b) add 6 to each side

c) subtract 3 from both sides

d) subtract 5 from both sides

Answer:

10(4-10m)

Step-by-step explanation:

You have to find something that can go out of both of the numbers.

10 is the highest that i could find.

So you basically have to put the number on the outside of the racks.

Then divide it.

40-100m

÷10 ÷10

whats left is 4-10m

The variable can't be divided with it since it doesn't have another variable to go with.

The expression '40 - 100m' can be factored by finding a common number, which, for 40 and 100, is 20. On factorizing the expression we get: '-20(2 - 5m)'.

The expression '40 - 100m' can be factored by finding a common number that both 40 and 100 can be divided by. This number is 20, but since we also have -100m, we'll use -20. Therefore, the factored form of '40 - 100m' is '-20(2 - 5m)'. Here is the step-by-step process.

Identify numbers that both 40 and 100 can be divided by evenly; in this case, 20.

Factor out the common number from the original expression, which gives '-20(2 - 5m)'.

Answer:

[tex]a=p=\frac{1}{6}\\\\b. \ p=\frac{1}{12}\\\\c.\ 1H,1T,2H,2T,3H,3T,4H,4T,5H,5T,6H,6T[/tex]

Step-by-step explanation:

a. A fair dice has 6 sides with unique identities.

-The sample space of one throw is 6 and each face has an equal chance of showing up.

-The probability of a 6 is calculated as:

[tex]p(six)=\frac{1}{6}\\\\or \ =0.1667[/tex]

Hence, the probability of a 6 is [tex]\frac{1}{6}[/tex]

b.A fair die has  6 unique faces.

-Two throws will have a sample space of 12.

-Each face has an equal probability of appearing twice.

-The probability of a 6 on both throws is:

[tex]P(six)=2\times \frac{1}{6}\\\\=\frac{1}{12}[/tex]

c. A coin has 2 sides(head, tail) and a die has 6 sides.

-The total sample space for the simultaneous throw of a coin and die is 12.

-The resultant sample space is :

Answer:

Step 1:  Set x to -1 in the first equation

[tex]f(x) = -x^2 + x[/tex]

[tex]f(-1) = -(-1)^2 + (-1)[/tex]

[tex]f(-1) = -(1) - 1[/tex]

[tex]f(-1) = -1 - 1[/tex]

[tex]f(-1) = -2[/tex]

Step 2:  Set x to -1 in the second equation

[tex]f(x) = -x[/tex]

[tex]f(-1) = -(-1)[/tex]

[tex]f(-1) = 1[/tex]

Step-by-step explanation:

Given:

Image of the figure

To find:

The area of the figure.

Solution:

The image is splitted into two shapes.

One is rectangle and the other is trapezium.

Reference image for answer is attached below.

Rectangle:

Length = 10 cm

Width = 2.8 cm

Area = length × width

        = 10 × 2.8

Area = 28 cm²

Trapezium:

Top base = 6 cm

Bottom base = 10 cm

Height = 7.2 - 2.8 = 4.4 cm

Area = [tex]\frac{1}{2} \times(b_1+b_2)\times h[/tex]

        [tex]$=\frac{1}{2} \times(6+10)\times 4.4[/tex]

        [tex]$=\frac{1}{2} \times16\times 4.4[/tex]

Area = 35.2 cm²

Area of the figure = 28 cm² + 35.2 cm²

                              = 63.2 cm²

The area of the figure is 63.2 cm².
