3.742 (rounded)
The distance formula is Example: (1,1) and (3,2) X1=1 X2=3 Y1=1 Y2=2 (3-1)2=4 and (2-1)2=1 4+1=5 The answer is going to be the square root of 5
Look at the markings between zero inches and one inch. There should be a larger mark right in the middle between the two. That's 1/2 (one half) inch. Right in the middle between 0 and 1/2 is a smaller mark - that's the 1/4 (one quarter) inch mark. On the other hand, the mark halfway between 1/2 and 1 inch is the 3/4 (three quarter) inch mark. In other words, the distance from zero to one inch can be divided into four equal steps with three marks in between; those are, respectively, 1/4 inch, 2/4 inch (= 1/2 inch), and 3/4 inch. 4/4 inch is equal to 1 inch.
3 3/8
1/3 = .333... 2/3 = .666... +___________ 3/3 = .999... = 1 Reason: For two numbers to be different there has to be another number that lies between them. Example: 3 and 4 are different because 3.5 is between them. Question: What number lies between .999... and 1? Answer: There isn't one. Conclusion: .999... = 1
By unit of length and distance and conversion ,we can say that 1 feet =12 in 4 feet =48 in ratio : 16 :48 1:3
4
The distance is 4
3-4 = -1 -21 the distance between -1 and -21 is -20 -20 -1 = -21
Points: (-4, 3) and (3, -1) Distance: (3--4)2+(-1-3)2 = 65 and the square root if this is the distance which is just over 8

Using the distance formula from (3, 1) to (7, 1) is 4 units
Use Pythagoras to find the distance between two points (x0,.y0) and (x1, y1): distance = √(change_in_x² + change_in_y²) → distance = √((x1 - x0)² + (y1 - y0)²) → distance = √((4 - 1)² + (-1 -2)²) → distance = √(3² + (-2)²) → distance = √(9 + 9) → distance = √18 = 3 √2
-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 There is a distance of 12.
The distance between the points of (4, 3) and (0, 3) is 4 units
Let's think of the graphs:||| 1------( y = 1 )-----|--------------------- (x axis)|| -1|| -2|| -3 -------( y = -3 ) -----------You can see the distance between these two lines is 4.You can just subtract the two lines, since they are parallel. 1 - (-3) = 4
(-1, -3) (2, 4)
Points: (-3, -4) and (-8, 1) Distance: square root of 50 or about 7.071 to three decimal places
