BRAINIAC IN LAW OF SINES?? Ill give brainlest and extra points​

Answer:

45 degrees

Step-by-step explanation:

because 2 and 5 are vertical angles they are therefore congruent by definition, 5 is half of one and one is a right angle so measure angle 2 = 45 degrees

Answer:

50

Step-by-step explanation:

The total of all 6 angles make a circle, which equals 360°. Using the information below the figure,

2 * m∠5 = 90°, since 2 * m∠5 = m∠1 and ∠1 is a right angle.

Because ∠1, ∠5, and ∠6 are on one side of line L, they must equal 180°, and if ∠1 equals 90°,

m∠5 + m∠6=90°.

Since 2 * m∠5=m∠1 and m∠1=90°, m∠1 must be 45°. And by Transitive Property, m∠6 also equals 90°.

If the total measure of the angles is 360° and ∠1, ∠5, and ∠6 add up to 180°, ∠2, ∠3, and ∠4 must also add to 180°.

m∠6=m∠3 - 20°. We know that m∠6 is 45°, so we put that into an equation. I am going to use x as the measure of ∠3.

45=x-20  >>>  20+45=x-20+20  >>>  20+45=x  >>>  65=x  >>>  x=m∠3  >>>  m∠3=65

m∠3=m∠4, so m∠3+m∠4=65+65, or 130. And like I said above, ∠2, ∠3, and ∠4 must add to 180°. 180 minus 130 (the measure of ∠3 + ∠4) = 50, which has to be the measure of ∠2

Answer:

[tex]4\dfrac{1}{6}\ \text{kilometers per minute}[/tex]

Step-by-step explanation:

The graph shows a proportional relationship between the number of kilometers traveled (y) and the number of minutes spent traveling (x). This graph passes through the point (75,30). This means that in 30 minutes (x = 30), it was traveled 75 kilometers.

To find unit rate, divide the number of kilometers by the number of minutes:

[tex]\dfrac{75}{30}=\dfrac{25}{6}=4\dfrac{1}{6}\ \text{kilometers per minute}[/tex]

well 4 is basically 1/5 of 20, so that would be about 20%

and since 4 x 4 is 16, my guess is that 16 is 80% of 20

Answer: 80%

Step-by-step explanation: To answer the question what percent of 20 is 16, we translate the question into an equation.

So we have "what percent" that's x, "of 20" means times 20, "is 16" = 16. So now we have the equation (x)(20) = 16.

Now to solve for x, since x is being multiplied by 20, we need to divide by 20 on both sides of the equation. On the left side of the equation the 20's cancel and we have x and on the right side of the equation we have 16 divided by 20 which is 0.8.

Now, remember that we want to write our answer as a percent so we need to convert 0.8 into a percent.

We can convert a decimal into a percent by moving the decimal point two places to the right so we can change 0.8 to a percent by simply moving the decimal point two places to the right and we have 80%.

This means that 80% of 20 is 16.

Answer: Domain = { -3 , 6 , 5 , -6}

Range = { 7 , 2 , -1 , -6 }

Step-by-step explanation:

considering the points given

[tex]x_{1}[/tex] = -3                                [tex]y_{1}[/tex] = 7

[tex]x_{2}[/tex] = 6                                [tex]y_{2}[/tex] = 2

[tex]x_{3}[/tex] = 5                                [tex]y_{3}[/tex] = -1

[tex]x_{4}[/tex] = -9                               [tex]y_{4}[/tex] = -6

This shows that that is relationship between the values of x and the values of y.

All the values of x represent the domain and all the values of y represent the range.

Therefore :

Domain = { -3 , 6 , 5 , -6}

Range = { 7 , 2 , -1 , -6 }

Answer:

The slope of f(x) is 1.5

Step-by-step explanation:

step 1

Find the slope of the linear function that has an x-intercept of 2/3 and a y-intercept of -1

so

we have the points

(2/3,0) and (0,-1)

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

substitute the values

[tex]m=\frac{-1-0}{0-2/3}[/tex]

[tex]m=\frac{-1}{-2/3}[/tex]

[tex]m=\frac{3}{2}=1.5[/tex]

step 2

Find the slope of the function graphed

take the points

(0,-1) and (3,6)  approximately

substitute in the formula

[tex]m=\frac{6+1}{3-0}[/tex]

[tex]m=\frac{7}{3}=2.33[/tex]

step 3

we know that

f(x) represents the function with the smaller slope

The smaller slope is 1.5

therefore

The slope of f(x) is 1.5

Answer:

BC=16.992

Step-by-step explanation:

Answer:

16.992

Step-by-step explanation:

Answer:

Step-by-step explanation:

buying the windows and having them installed costs $ 7699.25

installation alone costs 3325

therefore, the cost of the windows is : 7699.25 - 3325 = 4374.25

and if they are paying 230.25 per window, then there is

4374.25 / 230.25 = 18.997 windows

let me check something...

18 * 230.25 = 4144.50

19 * 230.25 = 4374.75

if ur numbers are written correctly, they can only buy 18 windows.....they would be short 50 cents from buying 19 windows

To determine the number of windows the Rayhills purchased, the total cost minus the installation cost was divided by the cost per window, leading to an estimate of approximately 19 windows.

To find out how many windows Rayhills bought, we need to subtract the installation cost from the total cost and then divide the result by the cost per window. The total cost of buying the windows and having them installed is $7,699.25, and the company charges $3,325 for the installation. If each window costs $230.25, we can calculate the number of windows as follows:

Now let's perform the division:

$4,374.25 / $230.25 ≈ 19 windows (rounded to the nearest whole number since you can't buy a fraction of a window).

Therefore, the Rayhills bought approximately 19 windows.

Answer:

y-4=-2(x+4)

Step-by-step explanation:

Perpendicular means negative reciprocal of the slope.

y-y1=m(x-x1)

y-4=-2(x-(-4))

y-4=-2(x+4)

The equation of the line that passes through the point (-4, 4) and is perpendicular to the line [tex]y = \frac{1}{2}x + 1[/tex] is [tex]y = -2x - 4[/tex].

To find the equation of the line that passes through the point (-4, 4) and is perpendicular to the line [tex]y = \frac{1}{2}x + 1[/tex], we need to do the following steps:

Determine the slope of the given line:
The slope of the given line [tex]y = \frac{1}{2}x + 1[/tex] is [tex]\frac{1}{2}[/tex].

Find the slope of the perpendicular line:
The slopes of two perpendicular lines are negative reciprocals of each other. Therefore, if the slope of the given line is [tex]\frac{1}{2}[/tex], the slope of the perpendicular line will be [tex]-2[/tex] (since [tex]-1 \div \frac{1}{2} = -2[/tex]).

Use the point-slope form to find the equation:
The point-slope form of a line is [tex]y - y_1 = m(x - x_1)[/tex], where [tex](x_1, y_1)[/tex] is a point on the line, and [tex]m[/tex] is the slope.
Here, the point is [tex](-4, 4)[/tex] and the slope [tex]m = -2[/tex].

Substituting these values into the point-slope form, we get:
[tex]y - 4 = -2(x + 4)[/tex]

Simplify the equation:
Distribute the slope on the right side:
[tex]y - 4 = -2x - 8[/tex]

Add 4 to both sides to solve for [tex]y[/tex]:
[tex]y = -2x - 4[/tex]

Answer:

Percent change is −31.19%.

Step-by-step explanation:

It is given that "a price of a dirt bike dropped from $872 to $600".

Initial price = $872

New price = $600

We need to find the Percent change.

[tex]\text{Percent change}=\dfrac{\text{New price - Initial price}}{\text{Initial price}}\times 100[/tex]

[tex]\text{Percent change}=\dfrac{600-872}{872}\times 100[/tex]

[tex]\text{Percent change}=\dfrac{-272}{872}\times 100[/tex]

[tex]\text{Percent change}=-31.19266[/tex]

[tex]\text{Percent change}\approx -31.19[/tex]

Therefore, the percent change is −31.19%.

Final answer:

The chance change in the price of the dirt bike is-31.2, indicating a  drop in price from$ 872 to$ 600.

Explanation:

To calculate the chance change in the price of a dirt bike that dropped from$ 872 to$ 600, we follow this formula given in the reference  Chance change = (( change in value)/( original value)) × 100  

First, we find the change in value, which is the new price abated from the original price $ 600-$ 872 = -$ 272  also, we divide this change by the original price  -$ 272/$ 872 ≈-0.312  

Eventually, to find the chance change, we multiply this bit by 100  -0.312 × 100 = -31.2  This means the price of the dirt bike  dropped by31.2.

410 / 23 = 17.8260869565

Lydia would need about 18 rolls of wallpaper to paper the walls of her kitchen.

Let X = the number of hours the server works.

The equation for the amount Nick spends is 15x + 47

The next job pays 14x + 54

Set the equations to equal and solve for x:

15x + 47 = 14x +54

Subtract 14x from both sides:

X + 47 = 54

Subtract 47 from both sides:

X = 7

Now replace x with 7 in the second equation:

14x + 54 = 14(7) + 54 = 98 +54 = 152

The job would pay $152 and be 7 hours long.

You know that m<TSU=m<PSR because they make a vertical angle pair.

So...m<PSR=4x.

If, m<QSR=3x then m<PSQ=4x-3x=x because they are adjacent.

And, m<PQS=180-68=112 degrees (linear pair).

Now we know all the interior angles in triangle PQS so we can say that...

x+x+112=180 (sum of interior angles in triangle)

2x=68

x=34 degrees

The requried value of x is 34 in each case, as of the given conditions

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
As given in the question,

PU ∩ RT = S, Q ∈ PR

Since the sum of the remote interior angles is equal to the sum of the remote exterior angles.
∠SPQ + ∠PSQ = ∠SQR
∠PSQ = 68 - x

Now, When two lines intersect each other, their alternate angles are equal,
∠TSU = ∠PSR
4x = ∠PSQ + ∠QSR
4x = 68 - x + 3x
2x = 68
x = 34

Thus, the requried value of x is 34.

Answer:

Tax on her normal wage is $ 6755

She can work 176 hours in a year and still remain in the same tax category

Step-by-step explanation:

Becky earns $633.81 for a 40 hour week.

Her normal monthly  wage is $ 633.81 *4 = $ 2535.24

Her annual income is $ 2535.2 *12=  $ 30,422.88

Tax on her annual income is  $30,422.88- $ 20,700= $9722.88

Tax on $ 20,700 is $ 3060

Tax on remaining $ 9722.88 is 0.38*9722.88=  $36,95

Total tax is $ 3060 + $ 3695= $ 6755

She can earn up to ( $ 36,000- $ 30, 423=) $ 5577 to remain in the same tax bracket.

She earns  $633.81/40= $ 15.84 in one hour

She gets twice the wage for the overtime  $ 31. 69

No of hours she can work = $5577/ $ 31.69 = 175.98 almost 176 hours
