If square LMNO is dilated by a scale factor of two about the center of the square to create square L'M'N'O', dilated line P'Q' w
Genrish500 [490]

Solution:

As given Square L M NO is dilated by  a scale factor of two about the center of the square to create square L'M'N'O'.

Original line of Dilation = Along P Q

New Dilated line = P'Q'

As scale factor > 1

1. Image Size > Pre image size

2. The two images will be similar.

3. Length of Dilated Line P' Q' = 2 × Length of PQ

As you can see from the diagram drawn below, Dilated line P'Q'  will contain the point P and Q.

All four points P,Q,Q',P' are collinear , lie in the same line.

Option (2) dilated line P'Q' will contain the points P and Q is true.

The chemistry class was making 300 gallons of 30% isopropyl alcohol. They mixed 12% with 42%. How much of each did they use?
alexgriva [62]

Answer:

<u>The chemistry class mixed 120 gallons of 12% isopropyl alcohol and 180 gallons of 42% isopropyl alcohol.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of isopropyl alcohol made by the chemistry class = 300 of 30%

Amount of 12% isopropyl alcohol mixed by the chemistry class = x

Amount of 42% isopropyl alcohol mixed by the chemistry class = 300 - x

2. How much of each did they use?

Let's write our equation to solve for x, this way:

30% = 0.3, 12% = 0.12, 42% = 0.42

0.12x + 0.42 (300 - x) = 0.3 * 300

0.12x + 126 - 0.42x = 90

-0.3x = 90 - 126

-0.3x = -36

x = -36/-0.3

<u>x = 120 ⇒ 300 - x = 180</u>

<u>Let's prove x = 120 is correct</u>

0.12x + 0.42 (300 - x) = 0.3 * 300

0.12 * 120 + 0.42 (300 - 120) = 0.3 * 300

14.4 + 75.6 = 90

90 = 90

<u>We proved x = 120 is correct</u>
