What's the formula to perimeter

Answers

Answer 1

Answer: The formula is:

Perimeter = (the distance all the way around the outside of the figure) .

How to calculate the distance all the way around the outside of the figure
is different for every shape.

A few of them are:

Square . . . . . 4 x the length of one side

Rectangle . . . . . (2) x (length + width)

Circle . . . . . (2 pi) x (radius)

etc.

Answer 2

Answer: $The\ perimeter\ of\ any\ polygon\ is\ the\ sum\ of\ the\ lengths \nof\ all\ its\ sides\ (a,\ b,\ c,\ d,\ ...)\n\ntriangle:\ \ \ P=a+b+c\n\nequilateral\ triangle:\ \ \ P=3a \n\nrectangle:\ \ \ P=2a+2b \n\nsquare:\ \ \ P=4 a\n\ndiamond :\ \ \ P=4a\n\ntrapez:\ \ \ P=a+b+c+d\n\nisosceles trapezoid:\ \ \ P=a+b+2c\ \ \ \ \ (c-arm length)\n\nany\ polygon:\ \ \ P=a+b+c+d+...\n----------------\nThe\ perimeter\ of\ a\ circle:\ \ \ P=2 \pi r\ \ \ \ \ (r-radius\ or\ a\ circle)$

they shared 3 pizzas that were each cut into 12 slices.

Step-by-step explanation:

Joe ate 4 slices.

paige ate 6 slices.

Darius ate 3 slices (12 ÷ 4 = 3).

hannah ate 4 slices (12 ÷ 3 = 4).

Brett ate 6 slices (12 ÷ 2 = 6).

Alex ate 12 slices (twice as much as Brett).

The probabilities of a test are represented by I for infected; U, uninfected; D, infection detected; and N, no infection detected. What is the symbolic way to represent the probability of a true positive?

Answers

A true positive is when a person who is infected receives a positive test (someone whose test comes back positive but who doesn't really have the infection would be called a false positive).

A symbolic way to represent the probability of a true positive would be the infection detected divided by the total of all the options:

D/(I + U + D + N)

2.0 is ???? times greater than 0.02

Answers

2.0 is 100 times greater than 0.02. When you have two numbers that are just separated by zeroes, simply count the number of zeroes and multiply the smaller number by a multiple of ten with the same number of zeroes to get the larger number. For instance, if you were to have 40 and 0.0004, you can just count the number of decimal places between them (in this case 4), and put the same number of zeroes behind a 1 (10,000). Then, if you multiply 0.0004 by 10,000, you should get 40. Likewise, if you multiply 0.02 by 100, you should get 2.
