A 50-centimeter piece of wire is bent into a circle. What is the diameter of the circle? What is the radius of the circle? What is the area of the circle?

Answers

Answer 1

Answer:

The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm

The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm

The area of a circle is given by \pi × square of radius

Area = 3.142 × 7.96×7.96 = 199.0821 square cm

Answer 2

Answer:

the diameter would be half of the original length because it needs to be a circle so each half of the circle would equal 25 centimeters

hope dis helps <3

1. How many cars per day does Car Mart sell? How did you use the table to find this rate?
2. How many cars per day does Winston's sell? Explain how you found this rate.
3. Which dealership sells more cars per day? How many more?
4. Which dealership started with more cars? How many more cars did that dealership start with?
Explain how you found your answer.

Answers

1. Car Mart sell 11 cars per day.
You can use the table by looking at day 2 and day 3. You can see underneath it, it shows how many cars is left after that particular day. So from day 2, you have 43 cars left and day 3, you got 32 cars left. From 43 car to 32 car is losing 11 car. So each day the Car Mart sell 11 car.

2. First we know that after 3 days, Winston have 32 cars left and after 5 day, it has 12 cars left.
Here’s the chart that I made for Winston:
Each day, Winston’s sell 10 cars. (Lose 10 cars per day)

1. Car Mart sells 11 cars a day.

2. Winston's sells 10 cars per day.

3. Car Mart sells one more car per day.

4. Winston started with more cars.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.

Rate for cart mart is (32 - 43)/(3 - 2) = - 11.

Car Mart sells 11 cars a day.

Winston's sells 10 cars per day.

Car Mart sells more cars per day.

As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.

As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.

Track teaches you to be able to achieve your best speed in one of the quickest ways possible. The activity supports the skill because the more mitochondria you have, the more energy you are able to produce during exercise, which will enable you to run with greater speeds. If track is done regularly, it increases the size of the mitochondria. Giving you more energy, which will generate more speed. ( Hope this helps! (: )

please help me with this thank you

Answers

Answer:

9670 feet

Step-by-step explanation:

The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?

we translate word problem to equation.

8219.5 IS 85% of TOTAL

Firstly, 85% = 85/100 = 0.85

Remember, is means =

of means multiplication

So we have:

8219.5 = 0.85 * Total

Hence, total = [let total be 7]

8219.5 = 0.85 * t

t = 8219.5/0.85 = 9670 feet

Step-by-step explanation:

i hope this helps

Power is the result of multiplying two numbers together. The inverse operation of a square root is a square.

What is power?

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The radical is the symbol that is used to represent the root in the expression n√x. When the value of n in this radical is 2, then it is known as the square root.

The inverse operation of a square root is a square, which means that the expression is needed to be multiplied by itself.

Hence, The inverse operation of a square root is a square.

Then the rope was removed, and he was flung into a cagelike crate. here he lay for the remainder of the weary night, nursing his wrath and wounded pride. Buck: And each time the joyful bark that trembled in Bucks throat was twisted into a savage growl. But the saloon-keeper let him alone and he could not understand what it all meant. What did they want with him, these strange men? Why were they keeping him pent up in this narrow crate? He did not know why, but he felt oppressed by the vague sense of impending calamity and in the morning four men entered and picked up the crate. Whereupon he lay down sullenly and allowed the crate to be lifted into a wagon. Then he, and the crate in which he was imprisoned, began a passage through many hands. Clerks in the express office took charge of him; he was carted about in another wagon; a truck carried him, with an assortment of boxes and parcels, upon a ferry steamer; he was trucked off the steamer into a great railway depot, and finally he was deposited in an express car. For two days and nights this express car was dragged along at the tail of shrieking locomotives; and for two days and nights Buck neither ate nor drank. In his anger he had met the first advances of the express messengers with growls, and they had retaliated by teasing him. He flung himself against the bars, quivering and frothing. He did not mind the hunger so much, but the lack of water caused him severe suffering and fanned his wrath to fever pitch. Buck:That had given them an unfair advantage; but now that it was off, he would show them. They would never get another rope around his neck. His eyes turned bloodshot, and he was metamorphosed into a raging fiend. Four men gingerly carried the crate from the wagon into a small, high-walled backyard. A stout man, with a red sweater that sagged generously at the neck, came out and signed the book for the driver. That was the man, Buck divined, the next tormentor, and he hurled himself savagely against the bars.
