PLEASE HELP 5 POINT ASSIGNMENT (LEASE TO GREATEST PROBLEM)

Answer:

1/2 < 3/5 < 2/3 < 5/6

Step-by-step explanation:

Using the given inputs:

1/2 5/6 2/3 3/5

The least common denominator (LCD) is: 30.

Rewriting as equivalent fractions with the LCD:

1/2 5/6 2/3 3/5

15/30 25/30 20/30 18/30

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

1/2 3/5 2/3 5/6

15/30 < 18/30 < 20/30 < 25/30

Therefore, the sorted inputs in order from least to greatest is:

1/2 < 3/5 < 2/3 < 5/6

using distance formula what is the distance point between (-8,4) and (-4,-1) round to nearest tenth ​
RideAnS [48]

Answer:

6.4 units

Step-by-step explanation:

Distance² = (change in y)² + (change in x)²

Distance² = (4 - -1)² + (-8 - -4)²

Distance² = 25 + 16 = 41

Distance = \sqrt{41} = 6.403124237

The distance is 6.4 units (rounded off to nearest tenth)
