Can I get some Help please

Answer:

165

Step-by-step explanation:

let the number of boys be x and girls be y.

But there are 175 more girls than boys, so y = x + 175

sum of boys and girls is 505

x + y = 505

and y = x + 175

x + x + 175 = 505

2x = 330

x = 165

Answer:

137°

Step-by-step explanation:

Total angle of a triangle:

a + b + c = 180°

35 + 8 + c = 180°

c = 180° - 43° = 137°

Answer:

4

Step-by-step explanation:

The system is:

[tex]\frac{x}{y}=2x + 4[/tex]

[tex]\frac{x-3}{y-3}=\frac{2}{3}[/tex] (y musn't be 3).

Solving for y in the first equation gives you:

[tex]y=\frac{x}{2x+4}[/tex]

Simplify the second equation to:

[tex]2(y-3)=3(x-3)[/tex]

Insert y you solved in first equation to second equation to get:

[tex]\frac{x}{x+2}-6=3x-3[/tex]

Further simplification gets you to quadratic equation:

[tex]x=(3x+3)(x+2)\implies x=3x^2+9x+6[/tex] [tex]3x^2+8x+6=0[/tex].

Solving quadratic equation using quadratic formula gives you two solutions of x in complex plane:

[tex]x_1=\boxed{-\frac{8}{6}+\frac{\sqrt{8}}{6}i}[/tex]

[tex]x_2=\boxed{-\frac{8}{6}-\frac{\sqrt{8}}{6}i}[/tex]

Insert the found x-es into first equation to find the y-s:

[tex]y_1=\boxed{-\frac{1}{2}+\frac{\sqrt{2}}{2}i}[/tex]

[tex]y_2=\boxed{-\frac{1}{2}-\frac{\sqrt{2}}{2}i}[/tex]

So there are two solutions (points) [tex]P_1(x_1,y_1),P_2(x_2,y_2)[/tex] both in [tex]\mathbb{C}[/tex] plane.

And the two fractions are:

[tex]\frac{-\frac{8}{6}+\frac{\sqrt{8}}{6}i}{-\frac{1}{2}+\frac{\sqrt{2}}{2}i}[/tex].

[tex]\frac{-\frac{8}{6}-\frac{\sqrt{8}}{6}i}{-\frac{1}{2}-\frac{\sqrt{2}}{2}i}[/tex].

Hope this helps.

Answer:

20 paitents

Step-by-step explanation:

In the word problem since x represents the number of hours all you have to do is plug in 5 for the x-value.

y = 4 (5)

once you do that, multiply 4 x 5 and you get 20.

Answer:

The answer is "GK=37, GH=14, and JK=19 ".

Step-by-step explanation:

In the question, an attachment file is missing.so, please find its attached file.

Given values:

GJ=4x+2

HK=6x-1

GK =37

Find:

HJ=?

GK = GJ+JK

     = GJ+(HK-HJ)

     = 4x+2+((6x-1)-x)

     = 4x+2+6x-1-x

     =  

9x+1...(a)

Solve equation (a) and put the value of x in the equation:

      =9(4)+1

       =36+1

       =37

find GH and JK=?

Given:

GK=37

Formula:  

GH = GJ-HJ

      = 4x+2- x

      = 3x+2....(b)

Solve equation (a):

GK= 9x+1

37=9x+1

36=9x

x=4....(c)

put the value of equation (b) in equation (c)

GH = 3x+2

      = 3(4)+2

      = 12+2

      = 14

Formula:

JK= HK-HJ

    = 6x-1- x

    = 5x-1

put the value of x in the above equation:

     = 5(4)-1

     = 20-1

     =19

-10.50 is not an integer number, it includes half of the unit (0.50)

Answer:

[-8, 7]

Step-by-step explanation:

The range is the set of values used for the y-coordinates of the all the points of the function.

The highest value of the function is at point (8, 7), so the greatest value y has is 7.

The lowest point of the function is at point (-3, -8), so the least value of y is -8.

Range: [-8, 7]

Answer:

[7, -8]

Step-by-step explanation:

Hello!

The range of a graph is found from looking at the graph from top to bottom

The highest point is 7 and the lowest point is -8

The range would be [7, -8]

Answer:

Option D. 11√6/2

Step-by-step explanation:

We'll begin by calculating the side opposite to angle 60°.

This is illustrated below:

Angle θ = 60°

Opposite =?

Hypothenus = 11

Using the sine ratio, we can obtain the side opposite to angle 60° as follow:

Sine θ = Opposite/Hypothenus

Sine 60 = Opposite /11

Cross multiply

Opposite = 11 × Sine 60

Sine 60 = √3/2

Opposite = 11 × √3/2

Opposite = 11√3/2

Finally, we shall determine the value of x as follow:

Angle θ = 45°

Opposite = 11√3/2

Hypothenus = x

Using the sine ratio, we can obtain the value of x as shown below:

Sine θ = Opposite/Hypothenus

Sine 45° = 11√3/2 /x

Cross multiply

x × Sine 45° = 11√3/2

Sine 45° = 1/√2

x × 1/√2 = 11√3/2

x/√2 = 11√3/2

Multiply through by √2

x = √2 × 11√3/2

x = 11√6/2

Answer:

10

Step-by-step explanation:

Given:

End points of a line segment are given as:

(2, 4) and (4, y)

Mid point of the line segment is: (3, 7).

To find:

Value of y = ?

Solution:

If end points of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then mid point of the line ([tex]x, y[/tex]) is given by The Mid Point Formula:

Mid point formula:

[tex]x = \dfrac{x_1+x_2}{2}\\y = \dfrac{y_1+y_2}{2}[/tex]

Here,

[tex]x_1 = 2\\x_2 = 4\\y_1 = 4\\y_2 = y\\[/tex]

[tex]x =3\\y=7[/tex]

Putting all the value to find [tex]y[/tex]:

[tex]7 = \dfrac{4+y}{2}\\\Rightarrow 4+y=14\\\Rightarrow \bold{y =10}[/tex]

So, the value of [tex]y[/tex] is 10.

Answer:

4(7+3x)

Step-by-step explanation:

We know that a square has all equal sides, otherwise it's not really a square. So if each side of the square is 7+3x units, then the perimeter (which is always side+side+side+side) would be 4 times as great. In other words, since the perimeter is side+side+side+side, and since that multiplication is repeated addition, 4(7+3x) is the same as (7+3x)+(7+3x)+(7+3x)+(7+3x)

Answer:

2

Step-by-step explanation:

Given

f(x) = | x - 4 | - 9, then

f(- 7) = | - 7 - 4 | - 9

        = | - 11 | - 9 ( absolute value returns a positive value )

        = 11 - 9

        = 2

Complete Question:

A twelve-sided die with sides labeled 1 through 12 will be rolled once. Each number is equally likely to be rolled, what is the probability of rolling a number greater than 10?

Answer:

[tex]P(T) = \frac{1}{6}[/tex]

Step-by-step explanation:

Given

Number of Sides = 12

Required

Probability of obtaining a side greater than 10

We start by listing out the sample space;

[tex]S = \{1,2,3,4,5,6,7,8,9,10,11,12\}[/tex]

[tex]n(S) = 12[/tex]

Next, we list out digits greater than 10; Represent this with T

[tex]T = \{11,12\}[/tex]

[tex]n(T) = 2[/tex]

Probability of T is calculated as follows;

[tex]P(T) = \frac{n(T)}{n(S)}[/tex]

[tex]P(T) = \frac{2}{12}[/tex]

Divide the numerator and denominator by 2

[tex]P(T) = \frac{1}{6}[/tex]

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

Answer:

This expression has no factors

Step-by-step explanation:

You can't factorize it because it has no factors.

If 14 were sqrt-able then there would have been a factor

G(X) = (X - 5)/X

Yes... The domain of G(X) can be any value, EXCEPT zero, because we cannot have a fraction with zero in the denominator

Formalizing the domain of this function: D = {X / X ≠ 0}

(for the sake of information, when X tends to zero, the function tends to +∞)

Answer:

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5).
