Find each percent increase round to the nearest percent from 86 books to 150 books

Stels [109]

From 86 books to 150 books. An increase of 64 books.

(150 - 86) / 86 = 64 / 86 = 0.744 * 100% = 74.40% or 74% increase

150 / 86 = 1.744 * 100% = 174.40%

86 is the basis. It is 100%

If the problem asks for the value of the percentage increase and the rate is given 74.4% of 86. Then 86 * 74.4% = 64. You just add 64 to 86 to get the new total of books which is 150.

Find the distance between (4,2) and (-4,-4)

VikaD [51]

Use the distance formula, and plug in values.
$d = \sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1} )^{2}}$
<u /> $d = \sqrt{( -4-4 )^{2}+( -4-2 )^{2}}$
$d = \sqrt{( -8 )^{2}+( -6 )^{2}}$
$d = \sqrt{64+36}$
$d= \sqrt{100}$

Therefore, the distance is equal to "10".
