Anyone know this?? Question: find the area of the shape. Don’t forget your units and use 3.14 if you need to use pi.

Answers

Quick answer :

Area of this shape = 614²

Answer with steps :

Length of side of the first square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the first square = 100²

Length of the side of the second square = 10

It's area :

[tex] = \tt \: side\times side[/tex]

[tex] =\tt 10 \times 10[/tex]

[tex] = \tt{100}^{2} [/tex]

Thus, the area of the second square = 100²

Length of the side of the third square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt 10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the third square = 100²

(pi value = 3.14)

Radius of the first semicircle = 10 cm

It's area :

[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]

[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]

[tex] = \tt\frac{3.14 \times 100}{2} [/tex]

[tex] =\tt \frac{314}{2} [/tex]

[tex] =\tt {157}^{2} [/tex]

Thus, the area of the first semicircle = 157²

Area of the second semi circle :

= area of the first semicircle

= 157²

Thus, the area of the second semicircle = 157²

Total area of the figure :

= Area of the 3 squares + Area of the two semi circles

[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]

[tex] = \tt300 + 314[/tex]

[tex] = \tt {614}^{2} [/tex]

Therefore, the total area of the figure = 614²

Solve for x, round to the nearest hundredths place.

cross-multiply:

28/20 can be simplified to be 7/5

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°

Answers

Answer:

m∠A = 50°

m∠B = 70°

m∠C = 60°

Step-by-step explanation:

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°

In a Triangle, the sum of the interior angles of a triangle = 180°

Step 1

We solve for x

Hence:

m∠A + m∠B + m∠C= 180°

(x-10)°+ (2x-50)°+ x° = 180°

x - 10 + 2x - 50 + x = 180°

4x - 60 = 180°

4x = 180° + 60°

4x = 240°

x = 240°/4

x = 60°

Step 2

Solving for each measure

x = 60°

m∠A=(x-10)°

= 60° - 10°

= 50°

m∠B=(2x-50)°

= 2(60)° - 50°

= 120° - 50°

= 70°

m∠C=x°

= 60°

What is an octagon?

An octagon is an 8-gon, or polygon with eight sides, in geometry. The Schläfli symbol for a regular octagon is 8, and it can also be built as a nearly regular truncated square.

The interior angle will be calculated as,

Angle = (n - 2) x 180

Angle = ( 8 - 2 ) x 180

Angle = 1080

Therefore, the sum of the interior angle measures of a convex octagon is 1080. the correct option is A.

Question 1 (5 points) A Big YearBy Bob KowalskiWould you go to the ends of the earth to see a bird? What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest?If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want.A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. For most in North America who participate in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast.You may be thinking that looking at birds is silly, but just think about the numbers of the recent record holders and the commitment it takes to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune.Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating.This honesty comes from the fact that most people who want to break such a record know the greatest rewards are not necessarily in winning. Such rewards are in being able to commit a year of your life to doing something you love. Rewards are found in seeing amazing, inspiring creatures like the California Condor or the Magnificent Frigate bird. Rewards also come in spending time with people who, like you, want to spend their time looking to the skies and trees for glimpses of emerald, crimson, or cerulean blue feathered jewels.You don't have to be able to travel a continent to have a big birding experience though. Have a big month. Or a big weekend. Set a personal record, learn to identify the species that live in your part of the world, or try to learn the calls of just two species of birds. You will soon find looking at birds isn't such a strange way to spend your time.Extra! Extra! Backyard BirdingMany schools, families, and young birders across the country participate in the "Great Backyard Bird Count." While not as long as a "Big Year," the "Great Backyard Bird Count" happens every year. It depends on birders and families across the country to watch feeders and other areas in their yards and count the number of birds they see. Unlike the "Big Year," the goal is not to see who can count the most birds. Instead, participants in this event work together to help bird experts get a good idea of how birds are doing. Participants are given checklists and enter their sightings on a website. Called a "citizen-science" project, this event is open to anyone, requires no travel, and happens every year over one weekend in February.Which of the following best states the main idea of the article "A Big Year"?(5 points)Question 1 options:1) "Big Year" birders compete for honor, love, and record-setting.2) "Big Year" birders get very competitive about seeing rare birds.3) "Big Year" birders have a list of important birds to see.4) "Big Year" birders compete to see more birds than others Jacob has 17 yards of fabric.
