The expected value of n is 1.152

The question states that ratio of 2n+2 and 2n-2 = 99:7. This means that

2n+2:2n-2 = 99:7, this also means that

[tex]\frac{2n+2}{2n-2}[/tex] = [tex]\frac{99}{7}[/tex]

If that is so, we can cross multiply so that

99 * (2n - 2) = 7 * (2n + 2), on expanding the bracket, we have

198n - 198 = 14n + 14

198n - 14n = 14 + 198

184n = 212, dividing both sides by 184, we have

n = 212/184

n = 1.152

Therefore, the value of n is 1.152

Step-by-step explanation:

Answer:

∠ R = 58° , ∠ Q = 32°

Step-by-step explanation:

Complementary angles sum to 90°

∠ Q is 26° less than ∠ R , so ∠ Q = ∠ R - 26° , then

∠ Q + ∠ R = 90° , that is

∠ R - 26° + ∠ R = 90°

2 ∠ R - 26° = 90° ( add 26° to both sides )

2 ∠ R = 116° ( divide both sides by 2 )

∠ R = 58°

∠ Q = 58° - 26° = 32°

Answer:Hi

Step-by-step explanation:  

Hi there!

We are given two exterior angles. Don't panic! We know that exterior angles form a linear pair, which means they add up to 180 degrees.

180-130=50

180-96=84

Now that we have those angles, how can we work out the value of x?

Turns out that all the angles in any triangle add up to 180 degrees.

So

180-84-50=46 degrees.

So the value of x is 46 degrees.

Now let's work out the value of x in the next problem.

180-126=54

180-54-43=83 degrees

So the value of x in this problem is 83 degrees.

Let's move on to the third problem.

At first, it seems like we do not have enough information.

If we know that the right angle is 90 degrees (it is shown by a little square), then we have enough information.

180-90-43=47 degrees

So the value of x is 47 degrees.

Hope this helps you!

Answer:

at point (4,4)

Step-by-step explanation:

Answer:

( 4 , 4 )

Step-by-step explanation:

Answer:

8. m∠1 = 64, m∠2 = 26, m∠3 = 36

9. m∠1 = 73, m∠2 = 58, m∠3 = 107, m∠4 = 49, m∠5 = 131

10. m∠1 = 34, m∠2 = 52, m∠3 = 38, m∠4 = 94, m∠5 = 56, m∠6 = 38

11. m∠1 = 62, m∠2 = 71, m∠3 = 109, m∠4 = 35, m∠5 = 109, m∠6 = 29, m∠7 = 47, m∠8 = 62

Step-by-step explanation:

8. m∠1 = 180 - (75 + 41) = 180 - 116 = 64

m∠2 = 90 - 64 = 26

m∠3 = 90 - 54 = 36

9. m∠3 = 180 - 73 = 107

m∠1 = 73

m∠2 = 180 - (73 + 49) = 180 - 122 = 58

m∠4 = 49

m∠5 = 180 - m∠4 = 180 - 49 = 131

10. m∠6 = 90 - 52 = 38

m∠3 = m∠6 = 38, m∠2 = 52

m∠5 = 180 - (86 + 38) = 180 - 124 = 56

m∠1 = 90 - 56 = 34

m∠4 = 180 - (34 + 52) = 180 - 86 = 94

11. m∠2 = 71

m∠3 = m∠5 = 180 - 71 = 109

m∠1 = 180 - (47 + 71) = 180 - 118 = 62

m∠4 = m∠2 - 36 = 71 - 36 = 35

m∠6 = m∠2 - 42 = 71 - 42 = 29

m∠7 = 47

m∠8 = m∠1 = 62

Answer:

3/8 is is bigger then 3/12

Step-by-step explanation:

The reason is that 3/12 is equivalent to 2/8 and 3/8 is equivalent to 6/16

Sorry if its wrong! ^^""

As, 0.375> 0.25, so, 3/8 is greater than 3/12.

Here, we have,

To get the answer, we first convert each fraction into decimal numbers.

We do this by dividing the numerator by the denominator for each fraction as illustrated below:

3/8 = 0.375

3/12 = 0.25

Then, we compare the two decimal numbers to get the answer.

0.375 is greater than 0.25.

i.e. 0.375> 0.25, as 0.375 - 0.25 = 0.125

Therefore, 3/8 is greater than 3/12.

Hence, As, 0.375> 0.25, so, 3/8 is greater than 3/12.

Answer:

Step-by-step explanation:

The lowest common denominator of 10 and 6 is 30.

9/10 = 3*9/10*9 = 27/30

1/6 = 5/1/(6 * 5) = 5/30

6 27/30 - 5/30 = 6 22/30 = 6 11/15

Answer 6 11/15

Answer:

20% increase

Step-by-step explanation:

the initial number is 110 so lets take that as a 100%

the final number is 132 and it will be x

110/132=100/x

we multiply the numerator of the first fraction with the denominator of the second fraction and vice versa.

110*x=132*100

110x=13200

x=120

Then we deduct 120 by 100 to know how much the percent increase is

(120-100)%=20% :)

The quadrilaterals that must have at least one pair of parallel sides include all of the following except trapezoid. This implies Rectangle, Square, Parallelogram, Kite, Rhombus

A quadrilateral is a four-sided polygon with four edges and four corners in geometry. The word comes from the Latin words quadri, a variant of four, and latus, which means "side." A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.

A rectangle is a quadrilateral with four right angles in Euclidean plane geometry. It can also be defined as an equiangular quadrilateral because all of its angles are equal; or a parallelogram with a right angle. A square is a rectangle with four equal-length sides.

A parallelogram is a simple quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are equal in length, and its opposite angles are equal in size.

We want to find equations for the different markups for the manufacturer and the stores that sell the crayons.

We know that a pack of 24 crayons costs $0.05 to make.

Is sold to stores for $0.25

The stores sell it for $0.50

Now we want to get the markup equation for the manufacturer, this is:

Markup = 100%*(price - cost)/(cost) = 100%*($0.25 - $0.05)/$0.05 =400%

For the store it is:

Markup = 100%*($0.50 - $0.25)/($0.25) = 100%

For the composition of these two I assume you refer to the total markup (notice that these are not functions, we can't make a composition if we do not have a variable).

Comp = 100%*($0.50 - $0.05)/($0.05) = 900%
