Answer:

Approximate decrease is 70%

Step-by-step explanation:

The percent decrease is the change over the new original / final value.  The change between the old and the new is 850 - 500, which is 350.  Thus the approximate percentage difference is

<u>350</u>

500

A quick way to turn anything with a denominator that starts with 5 and any number of zeros after it ... is to multiply both the top and bottom by 2.  That is, that turns the ratio above to:

<u>700 </u>

1000

Since a percentage is a number of 100, not 1000, just divide everything by 10.  That means take away a zero from each number, which gives you a fraction of:

<u>70 </u>

100

Thus, the result is 70/100, or 70%.

What are the coordinates of the midpoint of the segment whose endpoints are A (-1, -2) and B (6, 12)
Klio2033 [76]

<u>Answer:</u>

Mid point = (\frac{5}{2} ,5)

<u>Step-by-step explanation:</u>

We are given the coordinates of the end points of a line segment AB and we are to find the coordinates of its mid point.

The coordinates of the end points are: A (-1, -2) and B (6, 12).

We know the formula of the mid point:

Mid point = (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

So putting in the given values to find the mid point of line segment AB:

Mid point = (\frac{-1+6}{2} ,\frac{-2+12}{2} ) = (\frac{5}{2} ,5)
