Answer:

75

Step-by-step explanation:

All of the angles within the triangle must add up to 180 degrees. So, angle 2 =50

The angles 4,2,5 also equal 180 because they are on the blue line. Since angle 2=50 and angle 5= 55 angle 4 must be 75 which is needed to add up to 180.

Answer:

Angle 4 is 75°

b represent angle 2

d represent angle 4

70+60+b=180

130+b=180

b=50

55+50+d=180

The probability of rolling an 8 is:

Answer:  1/12

This is because there's one side we want (that's labeled "8") out of 12 sides total. This is of course if each side is equally likely.

Answers

Answer:

Option C. 6.5

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle B = 80°

Side opposite B (b) = 10

Angle C = 40°

Side opposite C (c) =?

We can obtain the value of c by using the sine rule as illustrated below:

b / Sine B = c / Sine C

10 / Sine 80 = c / Sine 40

Cross multiply

c × Sine 80 = 10 × Sine 40

Divide both side by Sine 80

c = (10 × Sine 40) / Sine 80

c = 6.5

Thus, the value of c is 6.5

Find the surface area of the rectangular prism below.

Answers

Answer:

Option B

Step-by-step explanation:

This is the formula :

2(wl+hl+hw)

Step 1 : Take the length, width, and height and substitute the values in.

The required surface area of the rectangular prism is 461.02 square meters (m²).

What is surface area?

Surface area is defined as the measure of a region or surface is called as surface area.

The surface area of a rectangular prism can be calculated by adding up the areas of all six faces. The formula for the surface area of a rectangular prism is:

Surface area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Substituting the given values, we get:

Surface area = 2(12.3m x 4.3m) + 2(12.3m x 10.7m) + 2(4.3m x 10.7m)

Simplifying the expression gives:

Surface area = 461.02m²

Therefore, the surface area of the rectangular prism is 461.02 square meters (m²).

The length of a rectangle is 3 ft longer than its width.
If the perimeter of the rectangle is 42 ft, find its area.

Answers

Answer:

A = 108 feet²

Step-by-step explanation:

Let the width is b.

Length = 3+b

Perimeter of the rectangle, P = 42 ft

Perimeter = 2(l+b)

42 = 2 (3+b+b)

21 = (3+2b)

21-3 = 2b

18 = 2b

b = 9 feet

Length, l = 3+9 = 12 feet

Area of the rectangle,

A = lb

So,

A = 12 × 9

A = 108 feet²

So, the area of the rectangle is 108 feet².

The length of a rectangle garden plot is 3 metres greater than its
width.The area of the plot is 154 square metres.What is the width of the garden?​

Answers

Answer: width = 11 m

Concept:

Here, we need to understand how to find the area of a rectangle.

In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.

A = w · l

w = width

l = length

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

w = w

l = w + 3

A = 154 m²

Given formula

A = w · l

Substitute values into the formula

154 = w · (w + 3)

Expand Parentheses (Distributive property)

154 = w² + 3w

Subtract 154 on both sides

154 - 154 = w² + 3w - 154

0 = w² + 3w - 154

Solve for the quadratic equation

(w - 11) (w + 14) = 0

w = 11 or w = -14 (Neglected because length cannot be negative)

Hope this helps!! :)

If two bags of popcorn and three drinks cost $14,
and four bags of popcorn and one drink costs
$18, how much does a drink cost?

Answers

Answer:

2dollars

Step-by-step explanation:

one bag of popcorn is 4 dollars so 4 bags of popcorn is 16 plus 1 drink which is 2 dollars equal 18.

The cost of each popcorn is $4 and the cost of each drink will be $2.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

If two bags of popcorn and three drinks cost $14, and four bags of popcorn and one drink costs $18.

Let the cost of each popcorn be 'x' and the cost of each drink be 'y'. Then the equations are given as,

2x + 3y = 14           ...1

4x + y = 18            ...2

From equations 1 and 2, then we have

2x + 3(18 - 4x) = 14

2x + 54 - 12x = 14

10x = 40

x = $4

Then the value of the variable 'y' is calculated as,

y = 18 - 4(4)

y = 18 - 16

y = $2

The cost of each popcorn is $4 and the cost of each drink will be $2.

Answers

Given YA = B, you can solve for Y by multiplying by A ⁻¹ on the right (on both sides of the equation). So we have

YA = B   ==>   (YA) A ⁻¹ = BA ⁻¹   ==>   Y (AA ⁻¹) = BA ⁻¹   ==>   Y = BA ⁻¹

provided that the inverse of A exists. In this case, det(A) = 5 ≠ 0, so the inverse does exist, and

[tex]A=\begin{bmatrix}-1&-4\\0&-5\end{bmatrix} \implies A^{-1}=\dfrac1{\det(A)}\begin{bmatrix}-5&0\\4&-1\end{bmatrix} = \begin{bmatrix}-1&0\\\frac45&-\frac15\end{bmatrix}[/tex]

Then

It takes 12 people 15 hours to complete and certain job.how many hours would it take 18 people, working at the same rate to complete 2/5 of the same job?

Answers

Answer:

2 Hours

Step-by-step explanation:

Required man hours to complete the full job = 12 *15

                                                                           =180 Man hours

Required man hours to complete the 2/5 of the job = 180/5

                                                                                      = 36 Man hours

if 18 peoples are working,

required hours to complete the 2/5 of the job = 36 /18

                                                                            = 2 hours

Answers

Answer:

0.8333

Step-by-step explanation:

Given :

Mean, X = 100

Lower Specification Limit, LSL = 100 - 10 = 90

Upper Specification Limit, USL = 100 + 10 = 110

Standard Deviation, σ = 4

The process capability index, Cpk;

Cpk = Min[(X - LSL) / 3σ; (USL - X) /3σ]

Cpk = Min[(100 - 90) / 12 ; (110 - 100 ) /12]

Cpk = Min [0.8333 ; 0.8333]

Hence, Cpk = 0.8333

I WILL GIVE BRAINLIESTThe Pollution Problem by Roberto BererraUnfortunately, pollution is like air: its everywhere! Pollution is the introduction of harmful substances into the environment that can cause damage and harm to humans, animals, and the environment. It takes on a number of different forms, from chemicals and garbage to something as seemingly innocent as light or noise.Pollution comes from a variety of sources. In addition, it alters, changes, and even destroys a variety of places. For example, exhaust from cars pollutes the air. When it rains, runoff from fertilizers and pesticides, which farmers use to help crops grow, can pollute the water in oceans, rivers, lakes, and streams. Garbage dumped in landfills is not only an eyesore, but also a source of harmful gases that can damage the earths atmosphere. Light pollution, which comes in the form of bright streetlights or signs, disrupts the view of the night sky. Noise pollution caused by cars, trucks, and machines interrupts the natural sounds of the world around us, such as birds singing or leaves rustling.The types of pollution and their effects vary greatly. At the same time, however, they are related; each type of pollution affects the other types. An example of the connection between different types of pollution is acid rain. Acid rain is caused mostly by sulfur or nitrogen emissions given off by sources such as car exhaust and the burning of fossil fuels such as coal. These harmful chemicals rise into the atmosphere where they react with other compounds and then fall as an acidic form of rain, sleet, or snow. Acid rain damages plants and buildings, contaminates soil and water, and has a negative effect on animals, fish, and even humans.Pollution has other effects, too. Breathing toxic air or drinking polluted water can cause humans and animals to develop health problems that can be serious and sometimes deadly. The deaths of too many members of a certain species of animal can upset the local ecosystem, or the area in which they live. As a result, weather patterns and climates can also change.Though pollution is everywhere, there are ways to help prevent it. By walking or riding bikesinstead of driving carspeople can help decrease air pollution. People can also buy and eat organic foods to support farmers that do not use fertilizers on their crops. It is also a good idea to take old things that people intend to throw away and find new ways to use them. A great way to help the environment is to recycle. Save items like used paper, glass and plastic bottles, and metal cans. Then, take them to a recycling center where they can be turned into new products to be used again. Some cities and towns even have recycling programs in place so all you have to do is leave your recyclable items on the curb on a certain day each week. It doesnt get much easier to help the environment and reduce pollution than that!The statements below make persuasive appeals to the reader about the dangers of pollution.
