Answer:

3

Step-by-step explanation:

When 2 lines are parallel, they have the same slope. Since m║n, the slope of m will be equal to the slope of n.

The required slope of line n which is parallel to line m is 3. Option D is correct.

Given that,
If m ∥ n and the slope of line m is 3, what is the slope of line n is to be determined.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The property of line state that, when lines are parallel to each the than the angle of inclination or slope of all the parallel lines are equal.
So, in given condition Line m is parallel to line n implies the slope of line m and n are equal.

Thus, the required slope of line n which is parallel to line m is 3.

Answer:

5 1/8 feets

Step-by-step explanation:

Given that:

PLAN A:

Length of post = 4.25 feets

Post must be 7/8 feets below the ground

Height of fence in PLAN A :

Converting 4.25 feets to decimal :

4.25 feets = 4 feets + 0.25 feets

0.25 feets = 1/4 feets

4 + 1/4 feets = 4 1/4 feets

4 1/4 feets + 7/8 feets

17 /4 feets + 7 /8 feets = [(34 + 7) / 8] feets

[(34 + 7) / 8] feets = 41/ 8 feets

41 / 8 feets = 5 1/8 feets

Answer:

It would cost the Lopez family $102.00 to go to Sealand

Step-by-step explanation:

Assume that the cost of each adult ticket is $x and the cost of each child ticket is $y

∵ The adult's ticket costs $x

∵ The child's ticket costs $y

∵ The Douglas family is charged $72.00 for 2 adult and 3 child tickets

∴ 2x + 3y = 72 ⇒ (1)

∵ The Williams family was charged $78.00 for 1 adult and 5 child tickets

∴ x + 5y = 78 ⇒ (2)

Let us solve the system of equations to find x and y

→ Multiply equation (2) by -2 to make the coefficients of x equal in

   values and different in signs

∵ -2(x) + -2(5y) = -2(78)

∴ -2x + -10y = -156 ⇒ (3)

→ Add equations (1) and (3) to eliminate x

∵ (2x + -2x) + (3y + -10y) = (72 + -156)

∴ -7y = -84

→ Divide both sides by -7 to find y

∴ y = 12

→ Substitute the value of y in equation (1) or (2) to find x

∵ x + 5(12) = 78

∴ x + 60 = 78

→ Subtract 60 from both sides

∴ x + 60 - 60 = 78 - 60

∴ x = 18

∴ The cost of each adult ticket is $18 and the cost of each child ticket

   is $12

∵ Lopez family has 3 adults and 4 children

∴ The cost of the tickets = 3(18) + 4(12) = 54 + 48

∴ The cost of the tickets = 3(18) + 4(12) = 102

∴ It would cost the Lopez family $102.00 to go to Sealand

Answer:

160

Step-by-step explanation:

It is given that, the ratio of student tickets to adult tickets sold is 4:3. Let students tickets is 4x and adult tickets is 3x.

Total no of tickets = 280

ATQ,

4x+3x=280

7x = 280

x = 40

Students ticket = 4x

= 4(40)

= 160

So, 160 students ticket is sold by Kiona.

The probability of obtaining a 6 and a head is 1/12 if Maureen rolls a fair dice and flips a coin.

It is a likeliness of happening an event. It lies between 0 to 1 .

Probability= Number of events/number of outcomes

When Maureen rolls a fair dice then probability of obtaining a six is 1/6

When Maureen flips a fair coin then probability of obtaining a head is 1/2

So the probability of obtaining a six and a head is 1/6*1/2

=1/12

Hence the probability of obtaining a six and a head is 1/12

Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

Answer:

The equivalent function of [tex]sin\left(180^{\circ }+x\right)[/tex] will be: [tex]-\sin \left(x\right)[/tex]

i.e.

[tex]\sin \left(180^{\circ \:}+x\right)=-\sin \left(x\right)[/tex]

Step-by-step explanation:

Considering the function

[tex]sin\left(180^{\circ }+x\right)[/tex]

Solving

[tex]sin\left(180^{\circ }+x\right)[/tex]

Using the angle sum identity:

[tex]\sin \left(s+t\right)=\sin \left(s\right)\cos \left(t\right)+\cos \left(s\right)\sin \left(t\right)[/tex]

[tex]=\sin \left(180^{\circ \:}\right)\cos \left(x\right)+\cos \left(180^{\circ \:}\right)\sin \left(x\right)[/tex]

as

[tex]\cos \left(180^{\circ \:}\right)=\left(-1\right)[/tex]

[tex]\sin \left(180^{\circ \:}\right)=0[/tex]

so

[tex]=0\cdot \:\cos \:\left(x\right)+\left(-1\right)\cdot \:\sin \:\left(x\right)[/tex]

[tex]=0\cdot \cos \left(x\right)-1\cdot \sin \left(x\right)[/tex]

[tex]=0-1\cdot \sin \left(x\right)[/tex]

[tex]=0-\sin \left(x\right)[/tex]

[tex]=-\sin \left(x\right)[/tex]

So, the equivalent function of [tex]sin\left(180^{\circ }+x\right)[/tex] will be: [tex]-\sin \left(x\right)[/tex]

Therefore:

[tex]\sin \left(180^{\circ \:}+x\right)=-\sin \left(x\right)[/tex]

Answer:

The Second Step.

Step-by-step explanation:

We are given the original equation:

[tex]12(5+2y)=4y-(5-9y)[/tex]

In her first step, Clare distributed both sides:

[tex]72+24y=4y-5-9y[/tex]

There are two errors:

First, the product of 5 and 12 is 60 and not 72.

Second, on the right-hand side of the equation, the negative must be distributed to all terms. Hence, the correct result should be:

[tex]\displaystyle 60 + 24y = 4y - 5 + 9y[/tex]

Instead of what she had obtained.

Answer:

  (x, y) = (-2, -1) or (2, 1)

Step-by-step explanation:

Substitute for x in the first equation:

  (2y)^2 +3(2y)y = 10

  10y^2 = 10

  y^2 = 1

  y = ±1

  x = 2y = ±2

Solutions are (x, y) = (-2, -1) or (2, 1).
