Answer: Here are the first four with how to.

Answer: I would pick black socks too because there are 8 pair of black socks with 4 pairs of white socks and 8 is > greater than 4.

Okay, so...

If there are 8 black socks + 4 white socks, then it = 12 socks totall. the fract Would Be 8/12 but if you simplify it, its 4/6, if you simplify it one more time you final answer is.....

You will have a 2/3 chance of picking a black sock.

Answer:

75°

Step-by-step explanation:

180°-105°=75°

Hope this helps! :)

Answer:

75 degrees.

Step-by-step explanation:

The sum of both angles is 180 degrees, they are supplementary. Therefore, subtracting the measurement of the first angle from 180 will give you your answer.

180 - 105 = 75

[tex]y = \frac{x - 8}{3} [/tex]

then change y and x place

[tex]x = \frac{y - 8}{3} [/tex]

now find y

[tex]y = 3x + 8[/tex]

so inverse function is f(×)=3x+8

Using simple mathematical operations we know that Sunita's truly hourly wage is $38.

The four mathematical operations are functions that change one number into another by taking input values, or numbers, as inputs.

They include addition, subtraction, multiplication, and division.

So, she works nine hours a day, after all.

She worked 162 hours total over the course of 18 days, or 18 x 9 hours.

Also, it is understood that she gets one paid day off for every 18 hours worked.

She is therefore paid for nine hours each day.

She is compensated for a total of 19 x 9 = 171 hours.

She receives hourly pay of $36,

Her total compensation is 171 divided by 36, or $6156.

Actual wages = Total amount she was paid/Total hours she worked

= 6156/612

= 38

Therefore, using simple mathematical operations we know that Sunita's truly hourly wage is $38.

Answer:

5.95cm

Step-by-step explanation:

Given data

Area of base of cone= 120π cm^2

Volume of cone= 240π cm^3

Area of base= Area of circle

Area= πr^2

120π= πr^2

120= r^2

r= √120

r= 10.9

r= 11cm

Let us find the height of the cone

The expression for the volume of cone is given as

V= 1/3πr^2h

240π= 1/3π*11^2*h

240= 1/3*121*h

240= 40.33h

divide both sides by 40.33

h=240/40.33

h= 5.95cm

Hence the height of the cone is 5.95cm approx

Answer:

x = 4 and y = -6

Step-by-step explanation:

Solve by elimination by multiplying the first equation by -2:

-8x - 6y = 4

8x + 3y = 14

Add them together and solve for y:

-3y = 18

y = -6

Plug in -6 as y into one of the equations and solve for x:

8x + 3y = 14

8x + 3(-6) = 14

8x - 18 = 14

8x = 32

x = 4

So, the solution is x = 4 and y = -6

Answer:

x = 4​

y = -6

Step-by-step explanation:

4x + 3y = -2

8x + 3y = 14​

Multiply the second equation by -1

4x + 3y = -2

-8x - 3y = -14

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

-4x       = -16

Divide by -4

-4x/-4 = -16/-4

x = 4​

4x+3y = -2

4*4 +3y = -2

16 +3y = -2

3y = -2-16

3y = -18

y = -6

Answer:

84

Step-by-step explanation:

m∠CMT=101-54=47

m∠PMA=37, So

m∠PMA+m∠CMT=47+37=84

The sum of the angle ∠PMA + ∠CMT will be 84 so option (D) will be correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

In other words, the angle is the measurement of the angular distance. For instance, we have a meter and an inch for linear motion, but we don't have a measurement for angular rotation, therefore the angle is helpful in determining angular rotation.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The Angle of description has given below

∠CMT=101-54=47

∠PMA=37, means

∠PMA+∠CMT = 47+37 = 84 hence, 84 will be the correct answer.

Answer:

[tex]x=1\frac{2}{9} +1\frac{1}{9}y[/tex]

Step-by-step explanation:

x - 3y + 8x - 7y = 5 + 6

9x - 10y = 11

9x - 10y + 10y = 11 + 10y

9x = 11 + 10y

9x ÷ 9 = 11 + 10y ÷ 9

[tex]x=1\frac{2}{9} +1\frac{1}{9}y[/tex]

Answer:

x = -1

y = -2

Step-by-step explanation:

x - 3y = 5     ----------------(I)

8x - 7y = 6 ----------(II)

Multiply equation (I) by (-8) and then add the two equations

(I)*(-8)     -8x + 24y = -40

(II)           8x   - 7y   = 6    {Now add and x will be eliminated}

                       17y = -34     {Divide both sides by 17}

                           y = -34/17

y = -2

Plugin  y  =-2 in equation (I)

x - 3*(-2) = 5

x  + 6 = 5         {Subtract 6 from both sides}

     x = 5 - 6

x = - 1

Answer:

16. 3

17. 12 / 7

18. 24 / 5 ( or ) 4.8

Step-by-step explanation:

16.

2 / ( x - 1 ) = 1

2 = x - 1

x = 2 + 1

x = 3

17.

( x / 3 ) + ( x / 4 ) = 1

LCM ( 3, 4 ) = 12

x / 3 = 4x / 12

x / 4 = 3x / 12

( x / 3 ) + ( x / 4 ) = 1

( 4x / 12 ) + ( 3x + 12 ) = 1

( 4x + 3x ) / 12 = 1

7x / 12 = 1

7x = 12

x = 12 / 7

18.

( x / 3 ) + ( x / 2 ) = 4

LCM ( 3, 2 ) = 6

x / 3 = 2x / 6

x / 2 = 3x / 6

( x / 3 ) + ( x / 2 ) = 4

( 2x / 6 ) + ( 3x / 6 ) = 4

( 2x + 3x ) / 6 = 4

5x / 6 = 4

5x = 24

x = 24 / 5

( or )

x = 4.8

Answer:

3√2 units

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, obtuse, acute and right angled triangle.

In a right angled triangle, the hypotenuse is the side with the longest length. Pythagoras theorem states that the square of the hypotenuse is equal to the sum of the square of the remaining two legs

The value of x can be gotten using Pythagoras theorem.

y² = h² + 3²   (1)

x² = h² + 3²   (2)

(3 + 3)² = x² + y² (3)

Substituting y² = h² + 3²  and x² = h² + 3² into equation 3 gives:

(3 + 3)² = (h² + 3²) + (h² + 3²)

36 = h² + h² + 9 + 9

2h² + 18 = 36

2h² = 18

h² = 9

h = 3

Put h = 3, into equation 2 to get the value of x:

x² = 3² + 3²

x² = 9 + 9 = 18

x = √18 = 3√2 units
