what is the area of the circle?

Answers

Answer 1

AC² = AB²+ BC²

AC² = (6)² + (8)²

AC² = 36 + 64

AC² = 100

AC = 10

diameter = AC = 10

radius = 5

A = πr²

A = π(5)²

A = 25π

The answer is C.

Summary of types of mixtures I need asap pls help meee

Answers

There are two main types of mixtures. They are:

Heterogeneous Mixtures; and Homogeneous mixtures. See further explanation below.

What is a mixture?

A mixture is a material composed of two or more separate chemical components that are not chemically linked. A mixture is the physical combining of two or more substances that retain their identities and are blended in the form of solutions, suspensions, and colloids.

Mixtures are classified into two types: heterogeneous and homogeneous. Heterogeneous mixes feature distinct components, whereas homogeneous mixtures look uniform throughout. A solution, which can be solid, liquid, or gas, is the most frequent form of homogeneous combination.

Examples of heterogeneous mixtures are:

oil and watersand and waterOil and wateroil and vinegarSolid earth and liquid watersmoke (gas + solid gas)Aerosol (gas + solid)Sparkling water (water + CO₂)

Examples of homogeneous mixtures are:

What is binomial probability?

The binomial distribution model allows us to calculate the likelihood of observing a specified number of "successes" when the process is repeated a certain number of times.

Let :

Sunny = S

Rainy = R

The probability that it rains on at least one day can be get using the binomial probability relation :

[tex]P=nCx*p^x*q^{n-x}[/tex]

[tex]P_{x=1}=3C1*0.5^1*0.5^2[/tex]

[tex]P_{x=1}=0.375[/tex]

Thus, the probability here is 0.375.

What is the positive difference between the circumference of circle B and the circumference of circle A?

Answers

The positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.

What is the circumference of the circle?

The circumference of the circle may be defined as the total stretch of the boundary of the circle. The formula for calculating the circumference of the circle is as follows:

C = 2πr.

where, C = circumference of the circle.

π = the constant pie.

r = radius of the circle.

According to the question,

The circumference of the circle A = 2π (r+1).

The circumference of the circle B = 2π (r+2).

∴The positive difference between the circumference of circle B and the circumference of circle A is as follows:

2π (r+2) - 2π (r+1) = 1.

Therefore, the positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.

If the expression n² - 2n - 8 represents the net profit
on the sale of n units of a product, which of the
following values represents the number of units
sold for which the net profit equals 0 dollars?
A) 2
B) 4
C) 6
D) 8

Answers

Option B) 4 is the number of units of product sold to get a profit of 0 dollars when the algebraic expression for profit is given.

the expression for net profit is [tex]n^{2}[/tex] -2n - 8 for the sale of n units of a product

If net profit equals 0 then

[tex]n^{2}[/tex] - 2n -8 =0

⇒[tex]n^{2}[/tex] - 4n + 2n - 8= 0

⇒ n ( n - 4) + 2(n - 4) = 0

⇒(n + 2)(n - 4) = 0

∴ n+ 2 = 0

⇒ n = -2

n - 4 = 0

⇒ n = 4

As the number of units of product sold cannot be negative, thus n cannot have a value of -2

The only remaining value is n = 4

Thus, 4 units of the product are sold for 0 dollars profit. Option B) 4 is the correct answer.

Answers

In the given figure, the length of BD is 14. The correct option is A.

What is the length?

Length is the measurement of the extent of something from one end to another, end. The SI unit of length is a meter (m).

Given, that AB is twice the length of BC

BC = CD

DE is a triple of CD

The length of AE is 19

Let's assume BC and CD = x

We have to calculate the length of the CD.

AB = 2x

DE = 3x

Putting the values:

2x + 3x = 49

7x = 49

x = 49 / 7

x = 7

BC and CD = x

7x + 7x = 14x

Therefore, the correct option is A. 14 regarding the given line.

Within a few decades, these resources had been decimated. Millions of birds and other wildlife were killed, some species to the point of extinction. Market shooting to supply food to restaurants, bounty hunting and unregulated sport hunting, and collecting feathers for the fashion industry all contributed to the loss. Millions of acres of wetlands were drained to feed and house the everincreasing population, greatly reducing waterfowl breeding and nesting habitat. Mother Nature has taken her toll with devastating droughts and floods that affect bird migration rest areas and wintering grounds. And climate change has the potential to alter bird populations in North America; estimates are that more than 300 species will be driven to smaller spaces or forced to find new places to live, feed and breed over the next 65 years. As well as providing habitat for wildlife, wetlands help maintain ground water supplies, filter pollutants, store flood waters, provide nurseries for many food sources, and protect shorelines from erosion. These provide important benefits to neighboring human communities. By buying Federal Duck Stamps, you can make a difference by providing wildlife habitat in your own community.BORN IN THE DUST BOWL DAYSIn 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act (or Duck Stamp Act), and an increasingly concerned nation took firm action to stop the destruction of wetlands vital to the survival of migratory waterfowl. Under the act, all waterfowl hunters 16 years of age and over must annually buy and carry a Migratory Bird Hunting and Conservation Stamp better known today as a Federal Duck Stamp. Ninetyeight cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase or lease wetlands and wildlife habitat for inclusion in the National Wildlife Refuge System. This ensures there will be land for wildlife and humans that will be protected for generations to come. Since 1934, some $800 million dollars has gone into that fund to protect more than 5.7 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated. One of the reasons for the Duck Stamp's success is that anyone can buy the stamp, which can also be used as an annual "pass" to national wildlife refuges charging entrance fees.WHY BUY DUCK STAMPS?Conservationists buy duck stamps because they know that 98 percent of the cost goes directly to conserve wildlife habitat vital for many birds, fish, mammals and plants, and you and your family and future generations. This small investment brings longterm returns. Stamp collectors purchase the stamp as a collectible that increases in value. Hunters, who strongly advocated for the Duck Stamp's creation, willingly pay the stamp price to ensure the survival of our natural resources. And many hunters buy two duck stamps each year one for hunting and one as a collector's item and an additional contribution to conservation. The Federal Duck Stamp has evolved over its more than 80 years of existence. In recognition of the stamp's growing value as a conservation tool, its formal name was changed to the Migratory Bird Hunting and Conservation Stamp.A) It presents historical information in chronological order throughout the text.B) It includes rhetorical questions to introduce each of the passage's main ideas.C) It explains background information about an issue and then presents new facts.D) It provides an introduction and uses main headings to break down key ideas.
