The value of y is 9.

Perimeter is the total length of the boundary of any closed shape. It is basically the sum of all the sides of a given figure.

Perimeter of a rectangle is given by [ 2( l + b ) ] or (2 l + 2 b ) or

( l + l + b + b), here l and b represent the length and breadth of the given rectangle.

Perimeter of the given rectangle = 166 units               ( given )

Length of the given rectangle = 5y                                ( given )

Breadth of the given rectangle = (4y + 2)                     ( given )

By putting values in the formula, we get

perimeter = 2 ( l + b )

166 = 2 [ (5y) + (4y + 2) ]

166 = 2 [ 5y + 4y + 2 ]

166 = 2 [ 9y + 2 ]

166 = 2*9y + 2*2

166 = 18y + 4

166-4 = 18y  ( moving 4 to other side thus changing the sign to negative )

162 = 18y

162/18 = y  ( moving 18 to other side for further solution )

y = 9

Therefore, the value of y for which the perimeter of the given rectangle is 166 units is 9.

The value of y is 9.

The whole length of any closed shape's boundary is known as its perimeter. In essence, it is the total of a given figure's sides.

A rectangle's perimeter can be calculated using [2(l + b)] or (2 l + 2 b) or

(l + l + b + b), where l and b stand for the provided rectangle's length and width

The rectangle's perimeter is 166 units ( given )

The rectangle's length is 5y ( given )

Given rectangle's width equals (4y + 2) ( given )

When we enter values into the formula, we obtain

perimeter = 2 ( l + b )

166 = 2 [ (5y) + (4y + 2) ]

166 = 2 [ 5y + 4y + 2 ]

166 = 2 [ 9y + 2 ]

166 = 2*9y + 2*2

166 = 18y + 4

166-4 = 18y  ( moving 4 to other side thus changing the sign to negative )

162 = 18y

162/18 = y  ( moving 18 to other side for further solution )

y = 9

Therefore, the value of y for which the perimeter of the given rectangle is 166 units is 9.

To solve this problem, we have to figure out the time spent travelling and then use the speed-distance-time equation to find the distance between the two places. The distance between Seattle and St. Louis is 2295 miles.

To calculate the miles or distance between Seattle and St. Louis, we have to take into consideration that out of the 42 hours she spent in her journey, she stayed 15 hours over at St. Louis.

\(42 - 15 = 27\)

She spent 27 hours travelling.

Her speed in the first journey was 50mi/h and her speed in the second journey was 35mi/h.

This implies she was faster in her first journey compared to her second journey.

Data;

\(speed = \frac{distance}{time} \\distance = speed * time\)

Let's substitute the values

\(distance = (50 + 35) * 27 = 2295mi\)

Dividend income and agricultural income are examples of tax exempt incomes.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

The right to have some or all of your income free from your country's taxes is known as a tax exemption. While certain individuals and organizations are completely exempt from paying taxes, the bulk of taxpayers are eligible for a number of exemptions that can be used to reduce their taxable income.

Income that is exempt from taxation is that which is unlikely to be taxed. Dividend income, agricultural income are a few examples.

Therefore, dividend income and agricultural income are examples of tax exempt incomes.

Step-by-step explanation:

Answer:

B. {(x, y): y = x²}

Step-by-step explanation:

A function is a graph where every input (x-value) has one and only one output (y-value). In other words if the value for x=2, there will only be one corresponding point for y. For the function in B, that y-value would be 4. Both A and D, solve for y, means taking the square root which leaves a +/- x-value. C is absolute value of y, which means the positive and negative values for y would have the same point. Only choice B has x-values corresponding to a singular y-value. If you can remember what these graphs look like you can test if they are functions based on the vertical line test.

0.03177

Step-by-step explanation:

Prob (Bld grp) ~ Bin (N, P)

N = 15, P = Prob of success ie 'O' blood type = 0.45

P (BG = 0) for 3 people = (N c X) P^X .  (1-P)^N-X

As X = 3. So Prob = (15 c 3) (0.45)^3 (0.55)^12

= 455 (0.091125) (0.0007662)

= 0.03177  

a. The  probability that exactly three have blood type O is 0.03177

Since

Prob (Bld grp) ~ Bin (N, P)

So

N = 15,

P = Prob of success ie 'O' blood type = 0.45

Now

P (BG = 0) for 3 people = (N c X) P^X .  (1-P)^N-X

So,

As X = 3. So Prob = (15 c 3) (0.45)^3 (0.55)^12

= 455 (0.091125) (0.0007662)

= 0.03177  

hence, The  probability that exactly three have blood type O is 0.03177

Thus, the measure of angle  m∠SQP = 87° for given set of vertically opposite angles.

An adjacent pair of additional angles is known as a linear pair. Adjacent refers to being next to one another, and supplemental denotes that the sum of the two angles is 180 degrees.

Any two angles that sum up to 180 degrees are referred to as supplementary angles.

For the given question:

m∠PQT = m∠SQR (vertically opposite)

101 - 4b = 109 - 6b

on simplifying:

109 - 101 = 6b - 4b

2b = 8

b = 4

m∠PQT = 101 - 4(4) = 93

Now,

m∠PQT +  m∠SQP = 180 (linear pair)

93 +  m∠SQP = 180

m∠SQP = 180 - 93

m∠SQP = 87°

Thus, the measure of angle  m∠SQP = 87° for given set of vertically opposite angles.

The minimum amount of plastic wrap needed to completely wrap 8 containers is  794. 4 in². Option D

The area of each circular end is:

A = πr²

A = 3.14 × (2.75)²

A = 23.68in²

The area of the rectangular side is:

A = h * circumference

circumference = 5.5in * π

circumference = 17.27in

Using the given height of 3 inches, we get:

A = 3in * 17.27

A = 51.81in²

Therefore, the total surface area of each container is:

A = 2 * 23.68 + 51.81

A = 98.17in²

To wrap 8 containers, we need to multiply the surface area of each container by 8:

In the given origami of the two dimensional figure , the value of angle 2 is 70° and the value of angle 1 is 110 °

Parallel lines are straight lines that do not intersect at any point in geometry.

Parallel planes are three-dimensional pathways that never intersect. Parallel curves do not touch or intersect and have a fixed minimum distance.

From the figure we can see that m∠1 = 4x-30 as they are vertically opposite angles.

Again m∠1 = 3x+5 as they are corresponding angles from the pair of parallel lines.

now let us solve the linear equation to calculate the value of x.

3x+5 = 4x-30

or, -x = -35

or, x = 35

Now

m∠1 = 3x+5 = 110

Therefore m∠2 = 180 -110 = 70 ( straight angle formed whose sum is 180)

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

The easiest way to solve this is to look at it as a whole.

Looking at a, you may be able to tell that it takes up a total of \(\frac{1}{4}\) of the shape. We know this because the lines stay in the very corners of the shape, and join together at the center.

Therefore, shape a takes up \(\frac{1}{4}\) of the space, 0.25 or 25%.

Before you look at the b shapes, think of the square as cut into fourths. A line going across, and diagonally. The b shapes take up \(\frac{1}{2}\) of that space, and then it is cut in half to form the two triangles. An equation to solve for the size of the triangles can look like this:

Therefore, the sizes of shape b are \(\frac{1}{16}\), 0.06 or 6.25%

Again for shape c, think of it as cut into fourths. Before, we solved for two triangles, but what about only one? Well, all we need to do is the same equation, but without dividing it by 2.

Therefore, the size of shape c is \(\frac{1}{8}\), 0.125, 0.25%

The last shapes, shape d are \(\frac{1}{4}\). We know this because half the shape is already taken up, and the last \(\frac{1}{2}\) is divided by 2,

\(\frac{1}{2}\) ÷ 2 = \(\frac{1}{4}\)

Therefore, the sizes of shape d are \(\frac{1}{4}\).

Step-by-step explanation:

Given

\(a_n = -3a_{n-1}\)

\(a_1 = 4\)

Required

Find \(a_4\)

\(a_4 = -3a_{4-1}\)

\(a_4 = -3a_3\)

We calculate for a3

\(a_3 = -3a_{3-1}\)

\(a_3 = -3a_2\)

Calculate for a2

\(a_2 = -3a_{2-1\)

\(a_2 = -3a_1\)

Substitute 4 for a1

\(a_2 = -3*4\)

\(a_2 = -12\)

Substitute -12 for a2 in \(a_3 = -3a_2\)

\(a_3 = -3 * -12\)

\(a_3 = 36\)

Substitute 36 for a3 in \(a_4 = -3a_3\)

\(a_4 = -3*36\)

\(a_4 = -108\)
