PLEASE HELP ASAPPPPP Find the value of x for mAB= 27° and mCD= 49°. The figure is not drawn to scale

Answers

Answer:

Step-by-step explanation:

The other guy has mislead other people. If i turned my thing in, I would have gotten a 90% instead of 100%.

It is A.

38 degrees.

The measure of x is (a) 38 degrees

The given parameters are:

[tex]mAB = 27^o[/tex]

[tex]mCD = 49^o[/tex]

The measure of x, is the average of angles AB and CD.

So, we have:

[tex]x = \frac{mAB + mCD}{2}[/tex]

Substitute known values of AB and CD in the above equation.

So, we have:

[tex]x = \frac{27^o + 49^o}{2}[/tex]

Add 27and 49

[tex]x = \frac{76^o}{2}[/tex]

Divide 76 by 2

[tex]x = 38^o[/tex]

Hence, the measure of x is (a) 38 degrees

In the diagram below, AB, BC and CD are three sides of a regular polygon.
The polygon has 15 sides.
The length of each side is 8 cm.
The exterior angle of the polygon is x.
BRC is a right-angled triangle.
Calculate the length of BR.
Thanks in advance

Answer:

BR is about 7.3084 cm

Step-by-step explanation:

the sum of the exterior angles of any polygon is 360. The measure ox x would be 360/15= 24

since I want BR, I will use cos (adj/hyp)

[? ]ft2

Answers

Answer:

300ft^2

Step-by-step explanation:

Total surface area = Area of base + (1/2) x perimeter of base x slant height

Area of base = length² = 10 x 10 = 100

Perimeter of base = 2 ( length + breadth)

2 x 20 = 40

slant height = 10

100 + (1/2) x 40 x 10 = 300 ft^2

Answers

Answer:

Perimeter is (width×height) but in this case it would be base×width & height...

First find the with of the triangle,by measureing the points with the base.

Second to find the base simply look equilateral and the half circle. and see how the lines in between it and the triangle collide. and count the spaces to find the base.

Third measure the height with the best estimate.

And finally, multiply by (h×w) and divide by the base.

Answer:

42,84

Step-by-step explanation:

Remark

Two of the sides are 12 inches. The third side is also 12 but it serves as a diameter of the semicircle.

The circumference of the semi circle is 2*pi*r /2 = pi * r

The total perimeter is pi * r + 2*12

r = d/2

r = 12/2

r = 6

Perimeter = 6*pi + 24 might be you answer.

Perimeter = 42.84

I don't know which answer to use. It all depends how other questions have been answered. Sometimes you take the decimal answer and sometimes you take the answer in terms of pi. I think the latter is what I would try first.

Assume that the probability of a defective computer component is 0.02. Components arerandomly selected. Find the probability that the first defect is caused by the seventh componenttested. Find the expected number and variance of the number of components tested before adefective component is found.

Answers

Answer:

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Step-by-step explanation:

Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.

First six not defective, each with 0.98 probability.

7th defective, with 0.02 probability. So

[tex]p = (0.98)^6*0.02 = 0.0177[/tex]

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

Find the expected number and variance of the number of components tested before a defective component is found.

Inverse binomial distribution, with [tex]p = 0.02[/tex]

Expected number before 1 defective(n = 1). So

[tex]E = \frac{n}{p} = \frac{1}{0.02} = 50[/tex]

Variance is:

[tex]V = \frac{np}{(1-p)^2} = \frac{0.02}{(1-0.02)^2} = 0.0208[/tex]

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

A

Find the inverse of f(x):

x = 3 + 6f⁻¹(x)6f⁻¹(x) = x - 3f⁻¹(x) = (x - 3) / 6

B

f · f⁻¹( ∛5/6) = f( f⁻¹( ∛5/6)) = f((∛5/6 - 3)/6) = 3 + 6((∛5/6 - 3)/6) =3 + ∛5/6 - 3 =∛5/6

A 2-kilogram bag of potting soil costs $1.96. What is the unit price?

Answers

Answer:

The unit price is $0.98

Answer:

98¢

Step-by-step explanation:

The unit price of an item is the price of one unit. In this case, this would be the price of a single kilogram.

To find the unit price, we'll divide the given price by the amount of units it is for. So, divide 1.96 by 2.

1.96 ÷ 2 = unit price

0.98 = unit price

This means the price of a single kilo of potting soil is $0.98. The unit price of the potting soil is 98 cents.

Step-by-step explanation:

Add all them up then make them equal 180 degrees

9x-9 = 180

Solve

9x=180 +9

9x= 189

9x/9= 189/9

x=21

Then plug in x to find each Angle.

N (x) Degrees

N=21 Degrees

M = 6x - 4

M = 6(21) - 4

Read the text from the following website: www.growingnation.orgA Growing NationAfter the American Revolution, the newly formed United States realized that it lacked room to grow. The states created in the Declaration of Independence in 1776 were limited in size. As the population increased, more people were competing for the same amount of land. Consequently, land became more expensive, and overcrowding became an issue. The thirteen states were bordered by the Atlantic Ocean and the territories of other nations. If the United States was going to have a future, it needed to increase its territory.President Thomas Jefferson believed that for Americans to be virtuous and free, they needed to farm land. He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States.The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict. The United States purchased Florida from Spain with the Florida Purchase Treaty of 1821. Instead of paying Spain a set amount, the United States would pay the $5 million Americans claimed were owed to them by Spain. After Texas declared independence from Mexico, it was annexed by the United States and became an official state in 1845. Another land controversy occurred between Great Britain and the United States, as both countries claimed the Oregon region. The dispute was settled in the 1846 Oregon Treaty, which separated the countries by the line of the 49th parallel. Mexico refused to let the United States buy California and New Mexico, so the two countries eventually went to war. Because the Americans won the war, the United States was able to buy lands in the Southwest in 1848. The United States paid Mexico $10 million for an area of land in the Southwest in the 1853 Gadsden Purchase, stretching its borders from sea to sea.According to information in the text feature, in what year did the United States officially obtain land with access to the Pacific Ocean?1845184818211846 The cation that has the same number of electrons (isoelectronic) as Ne isNone of the listed optionsO NaMg 2-All of the listed optionsO AI 3- 24.
