The distance between the two points pictured is d= Vn
katrin [286]

the distance between points is:

d = 7.8 units

 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)

 The ordered pairs are:

 (x1, y1) = (- 3, -2)

 (x2, y2) = (2,4)

 By applying the formula we have:

 d = root ((2 - (- 3)) ^ 2 + (4 - (- 2)) ^ 2)

 d = root (61)

 d = 7.8

A kite is flying 9.75 feet above a lamp post that is 84 2/3 feet tall. How high is the kitchen flying?
Elden [556K]

The kite is flying at the height of 94 5/2 feet.

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation.

= 9.75 +84 2/3                                               { 9+0.75 = 9.75   84 2/3}

= 9 + 0.75 +84 2/3                                           { a+b+c+d = a+c+b+d}

= 9 + 84 + 3/4 + 2/3

=93 + 3*3 / 4*3 + 4*2 / 4*3

= 93 + 9/12 + 8/12

= 93 + 17/12

= 93 + (1 + 5/12)

= 94 + 5/12

=94 5/12 feet

{kite height = (post height + the height of the kite above the post)
