Step-by-step explanation:

The is a parallel to b and m is parallel n.

Given that

To find

So, according to the question

We have,

and the value of two angles m∠2 and m∠4.

From diagram we can see a is parallel to b and m is parallel to n.

So, we can say that

   m∠4 = m∠3    { they are vertical congruent angles } and

   m∠3 = m∠2    { they are congruent angles}

∴  m∠4 = m∠2 -------------(1)

Now, putting the values in equation(1)

So, will be get

                m∠4 = m∠2 -------------(1)

              11x+16 = x²+5x

  x²+5x - 11x-16 = 0

         x²- 6x-16 = 0  

    x²-8x+2x-16 = 0  

  x(x-8)+2(x-8) = 0

        (x-8)(x+2) = 0

If               (x+8) = 0

                      x = 8

And if        (x+2) = 0

We can use the distance equation to help us solve this question:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Plug in the given points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-(-4))^2+(-7-(-2))^2}\\d=\sqrt{(8+4)^2+(-7+2)^2}\\d=\sqrt{(12)^2+(-5)^2}\\d=\sqrt{144+25}\\d=\sqrt{169}\\d=13[/tex]

The length of line segment BC is 13 units.

Using the distance formula, the length of BC is: 13 units.

Given that:

B(8, -7) = (x1, y1)

C(-4,-2) = (x2, y2)

The distance formula that would be used to find BC is, d =[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Thus, applying the distance formula, we have:

BC = √[(−4 − 8)² + (−2 − (−7))²]

BC = √[(−12)² + (5)²]

BC = √(144 + 25)

BC = √169

BC = 13 units

Therefore, using the distance formula, the length of BC is: 13 units.

Answer:

No solution

Step-by-step explanation:

The sides of the equation are unbalanced, therefore, the equation has no solution. Here's an example(The problem is not designed to mathematically make sense).

In the given particular sum we have to give reason why asolving 4 = 2x uses the division property of equality.

The reason for that why it is using division property of equality we wneed to know what is division property of equality : It states that when both side of the equation is divided by a real number other than 0 then the quotients remain same . It can be written as following : if a,b,c are real numbers where a = b , c ≠ 0 then ac = bc

for example suppose we have two breads of same size . We cut each of them into halfs and give it to  our friends , if we measure the remaining portions we will see that we are left with same portions of bread . Here at initial both the breads were same and we divide it by 2 and find that they are still same.

If the 6% sales tax had been computed on the sale price instead of on the regular price, the tax will be $0.04 lower.

It should be noted that from the information, Samwell bought a packet of pens and his receipt is shown above as $2.04.

Assume that sales tax is rounded to the nearest cent, If the 6% sales tax had been computed on the sale price instead of on the regular price, the difference will be:

Sales price = $1.89

Tax = $1.89 × 0.06 = $0.11

Therefore, the difference will be:

= Former tax amount - New tac amount

Answer:

You would need to score a 10.

The equation is going to have a total of 5 values where one is unknown. We will call this unknown x and include it as a value in the equation.

Since we are going to have to find an average, we will need a fraction. We also know we will take five total tests. This will equal 12 as this is the desired average.

To start, create the fraction that will add all five values together and divide that by the number of values.

[tex]\displaystyle \frac{12+14+11+13+x}{5}[/tex]

Then, set this equal to 12.

[tex]\displaystyle \frac{12+14+11+13+x}{5}=12[/tex]

To solve, we will first combine all like terms.

[tex]\displaystyle \frac{50+x}{5}=12[/tex]

Then, divide the fraction.

[tex]\displaystyle 10+\frac{x}{5}=12[/tex]

Now, move the constants to the right side of the equation. To do this, subtract 10 from 12.

[tex]\displaystyle \frac{x}{5}=2[/tex]

Finally, multiply both sides of the equation by 5 to get rid of the denominator.

[tex]x=10[/tex]

Therefore, on test 5, you must score a 10 to maintain an average of 12.

The midpoint between two points A(0,0) and B(8,4) is (4,2)

The distance between two points A(0,0) and B(8,4) is 4√5

To find the midpoint of two points,

We need to take an average of both the x and y components of both points

Two points A(x ₁,y₁) and B(x₂ ,y₂) are (0,0) and (8,4) respectively

Let M be the mid-point M(x, y),

x = x₁+x₂/2

 = 0+8/2

= 8/2

= 4

Similarly

y = y₁+y₂/2

  = 0+4/2

  = 4/2

  = 2

So, the midpoint of the two points A(0,0) and B(8,4) is (4,2)

To find the distance between two points,

We need to take the square root of the difference square of x and y, which is

d² = Δx² + Δy²

d = √(Δx²+Δy²)

Δx = x₂-x₁

    = 8-0

   = 8

Δy = y₂-y₁

    = 4-0

    = 4

Thus,

d = √(8²+4²)

d = √(64 + 16)  

d = √80

d = 4√5

The inequality that is represented by the given graph is; y > 2x + 1

From the given graph, we have the following points coordinates;

(x1, y1) = (2, 5)

(x2, y2) = (6, 13)

The formula to calculate the slope is;

m = (y2 - y1)/(x2 - x1)

Thus;

m = (13 - 5)/(6 - 2)

m = 8/4

m = 2

On the graph, we have the following observations:

The line of the graph is a dashed line (this represents > or <)

The upper part is shaded (this represents >)

The perimeter of the whole figure includes the sum of the side lengths and the value is -2 - 4m units

The area of a shape is the amount of space on the shape.

For most regular shapes, the area is the product of their width and the length

The area of this rectangle is given as

Area = 3m - 7m - 6

Evaluate the like terms

So, we have

Area = -4m - 6

The common factor of 4 and 6 is 2

So, we have the following equation

Area = 2(-2m - 3)

The area of the rectangle is

Area = Length * Width

So, we have

Length, L = 2

Width, W = -2m - 3

The perimeter of the rectangle is calculated as

P = 2 x (L + W)

So, we have

P = 2 x (2 - 2m - 3)

Evaluate the like terms in the above expression

So, we have

P = 2 x (-1 - 2m)

The percentage of people living on boat in Florida is 15.4%. The equivalent of this percentage to decimal is 0.154 and to fraction is 77/500.

55% live in a house, 25% live in an apartment, 4.6% in condo while the rest live on a boat. If all the percentages are summed up, they must be equal to 100%.

Let a% equals to the percentage of adult living on boat

55+25+4.6+a = 100

84.6 + a = 100

Collect like terms

a = 100 - 84.6

a = 15.4%

Therefore, the percentage of adult living on boat is 15.4%

To convert the percentage to decimal equivalence, one must divide it by 100%

15.4%/100%

= 15.4/100

= 0.154

To convert the percentage to fraction equivalence, one have to divide it by 100%

15.4%/100%
