How do you work out the size of angle x ?

Answer:

Martin saved $75 on the television because of the sale

Step-by-step explanation:

Equations

Let's call x=the original price of the television (before discount).

The television had been on sale for 25% off, this means the discount was:

25% of x = [tex]\frac{25}{100}.x[/tex] = 0.25x

The sale price was the original price minus the discount:

x - 0.25x = 0.75x

This is what Martin paid, thus:

0.75x = 225

Dividing by 0.75:

x = 225 / 0.75

x = $300

The original price of the television was $300, and the discount was:

0.25*$300 = $75

Martin saved $75 on the television because of the sale

Answer:

Draw a line of best fit to predict

Answer:

There are no solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

9m−4=−3m+5+12m

Step 1: Simplify both sides of the equation.

9m−4=−3m+5+12m

9m+−4=−3m+5+12m

9m−4=(−3m+12m)+(5)(Combine Like Terms)

9m−4=9m+5

9m−4=9m+5

Step 2: Subtract 9m from both sides.

9m−4−9m=9m+5−9m

−4=5

Step 3: Add 4 to both sides.

−4+4=5+4

0=9

Answer:

Its no solution

Step-by-step explanation:

1)Combine like terms

2)Letters with numbers in one side and only Number on the other side

3)Solve

9m – 4 = -3m + 5 + 12m

    9m-4=9m+5

  9m-9m=4+5

            0=9

Answer:

c

Step-by-step explanation:

Answer:

(A) 18

(B) 45

(C) 51.2  

Step-by-step explanation:

(A, 0.6 of 30) We need to find out 0.1 of 30 so we divide 30 by 10 which gives us 3. This means that 0.1 of 30 is 3. Since we know that, we multiply 3 by 6 which gives us 18.

(B, 1.5 of 30) Since we figured out that 0.1 of 30 is 3 on the first question, we can multiply 3 by 15 which gives us 45.

(C. 1.6 of 32) We need to find out 0.1 of 32 so we divide 32 by 10 which gives us 3.2. Now, we divide 3.2 by 16 which gives us 51.2.

I really hope that you understand. Also, I didn't really understand the question so I kind of guessed what the question was. But the answers are 99% accurate. The 1% is that I might have gotten the equations wrong.

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

Both vertical lines are parallel to each other. (given)

Similarly, both horizontal lines are also parallel to each other.. (given)

So, quadrilateral obtained by the intersection of both vertical and horizontal lines is a rectangle.

Therefore,

[tex] \angle 7 \cong \angle 6... (1)[/tex]

(corresponding angles)

[tex] \angle 6 \cong \angle 5... (2)[/tex]

(corresponding angles)

From equations (1) & (2)

[tex] \angle 7 \cong \angle 5... (3)[/tex]

(By Transitivity)

[tex] \angle 5 \cong \angle 10... (4)[/tex]

(vertical angles)

From equations (3) & (4)

[tex]\huge \purple {\boxed {\angle 7 \cong \angle 10}} [/tex]

(By Transitivity)

There are several other ways to prove it as well.

Answer:

Velocity of plane is 100 mi/hr along northeast direction

Step-by-step explanation:

From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction

since the velocity of wind and plane is exactly opposite

⇒ relative velocity of plane with respect to wind is given by

[tex]v_r_e_l = v_p - v_w[/tex] where [tex]v_p[/tex] is the velocity of plane = 150mi/hr and [tex]v_w[/tex] = velocity of wind = 50 mi/hr

Therefore, [tex]v_r_e_l = v_p - v_w[/tex]  = [tex]v_r_e_l = 150 - 50 = 100 mi/hr[/tex] alond northwest direction

Therefore, velocity of plane is 100 mi/hr along northeast direction

By working with the velocity vectors, we will find that the direction of motion of the plane is 28.7 south of east.

First, we need to define our coordinate axis, I will define the x-axis as the east and the y-axis as the north.

We know that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.

So the vector is:

V =  < 147.7 mi/hr,  -26 mi/hr >

Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°, so the components of the vector are:

So the vector is:

W = < -35.4 mi/hr, -35.4 mi/hr>

The sum of the vectors gives the total velocity of the plane in the wind, we will get:

V + W =  < 147.7 mi/hr -35.4 mi/hr ,  -26 mi/hr -35.4 mi/hr >

V + W =  <112.3 mi/hr, -61.4 mi/hr>

The direction of a vector <x, y> is given by:

θ = Atan(y/x)

Then in this case the direction of the plane is:

θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°

So the direction of the plane is 28.7° south of east.

0.1 or 1/10 yards

So we know that Colton cut 1⁄2 of a yard of ribbon into equal pieces to make the decorations so what we can do is take that 1⁄2 and divided by 5 because we know that there are 5 dancers at his year end dance performance.

1⁄2 in a decimal form is 0.5 so 0.5 divided by 5 equals 0.1 or 1/10.

Answer: -1/8

Step-by-step explanation:

3/4 + -3/8 + -1/4

Find the LCM of 4, 8, and 4

That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.

3/4 = 6/8

-3/8 = -3/8

-1/4 = -4/8

Now the expression looks like this:

6/8 + - 3/8 + -4/8

6/8 - 3/8 - 4/8

6/8 - 7/8

-1/8

Step-by-step explanation:

solution

let,A(5,-1)

given

y=12x-1

or, y = 12 × x + (-1)

comparing it with y=mx+c

we get

x=1

y = c = -1

now

A(5,-1) and B(1,-1)

equation of line is,

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

or, (y+1)/(x-5) = (-1+1)/(1-5)

or, (y+1)/(x-5) = 0/-4

cross multiply

-4y-4 = 0

or, 0=4y+4

or, 4y+4=0 is the required eqn

<R = 47 degrees

<S = 47 degrees

<T = 86 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180degrees

Given triangle RST

<R + <S + <T = 180

9x + 2 + 13x - 18 + 17x +1 = 180

39x - 15 = 180

39x = 180 + 15

39x = 195

x = 195/39

x = 5

Get <R

<R = 9x + 2

<R = 9(5) + 2

<R = 47 degrees

Get <S

<S = 13x-18

<S = 13(5) - 18

<S = 65-18

<S = 47 degrees

Get <T

<T = 17x + 1

<T = 17(5)+1

<T = 85+1

<T = 86 degrees
