ok this isn’t my answer i found it on quora but it answers ur question u have

We can write a system to solve this problem

Let x= the radius of Circle A

Let y=the diameter of Circle B

x=2y-3

2x+y=49

since we are trying to find the area and the circumference of circle A, we only have to find what x is

x=2y-3 → y=1/2x+3/2

next, we plug in 1/2x+3/2 for y:

2x+1/2x+3/2=49

we can then multiply all the numbers by 2 to get rid of the fractions:

4x+x+3=98

5x+3=98

5x=95

x=19

Circle A radius=19ft

Finally, we solve for the area and circumference:

Area:

A=pi*r^2

A=3.14*19^2

A=1133.54 feet^2

Circumference:

C=2*pi*r

C=2*3.14*19

C=119.32 feet

Answer:

not similar

Step-by-step explanation:

For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...

180° -81° = 99°

If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.

ABC angles: 60°, 81°, 39°

FED angles: 59°, 81°, 40°

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.

Answers

Answer:

ok let me try this again

To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

Find the approximate radius a circle if its circumference is 37.68 inches. Use (pie symbol)= 3.14.

Answers

Answer:

radius = 6 inches

Step-by-step explanation:

37.68/3.14 = 12 = diameter

radius = 12/2 = 6 inches

Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 314)
r = 6

Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04

Answer:
The area of the circle is 113.04 square units

need to finish soon please help Thanks to the field of linguistics we know much about the development of the 5,000 plus languages in existence today. We can describe their grammar and pronunciation and see how their spoken and written forms have changed over time. For example, we understand the origins of the Indo-European group of languages, which includes Norwegian, Hindi and English, and can trace them back to tribes in eastern Europe in about 3000 BC.So, we have mapped out a great deal of the history of language, but there are still areas we know little about. Experts are beginning to look to the field of evolutionary biology to find out how the human species developed to be able to use language. So far, there are far more questions and half-theories than answers.Find in this text 6 noun and 6 adverd and 6 adjectives and 6 noun phrase and 6 Adverbial clause We know that human language is far more complex than that of even our nearest and most intelligent relatives like chimpanzees. We can express complex thoughts, convey subtle emotions and communicate about abstract concepts such as past and future. And we do this following a set of structural rules, known as grammar. Do only humans use an innate system of rules to govern the order of words? Perhaps not, as some research may suggest dolphins share this capability because they are able to recognise when these rules are broken.
