Ne4ueva [31]

Answer:

242 pages.

Step-by-step explanation:

Let x represent number of pages that Claudia read last week.

We have been given that Claudia is reading a book that has 360 pages. She read some of the book last week. She plans to read 46 pages today. When she does,she will be 4/5 of the way through the book.

The number of total page left after reading 46 pages and x pages last week will be equal to 4/5 of 360.

We can represent this information in an equation as:

$x+46=\frac{4}{5}\cdot 360$

Let us solve for x.

$x+46=4\cdot 72$

$x+46=288$

$x+46-46=288-46$

$x=242$

Therefore, Claudia read 242 pages last week.

20 liters of mixture contain milk nad water in the ratio 5:3 of 4 liters of the mixture are replaced by 4 liters of milk find th

pantera1 [17]

Answer:

7:3

Step-by-step explanation:

5 + 3 = 8

The ratio is

5 milk : 3 water : 8 total

Milk is 5/8 of the total.

Water is 3/8 of the total.

The 20-liter mixture contains:

5/8 * 20 = 12.5 liters of milk, and

3/8 * 20 = 7.5 liters of water

4 liters of the mixture contain:

5/8 * 4 = 2.5 liters of milk, and

3/8 * 4 = 1.5 liter of water

When you remove 4 liters of the mixture from 20 liters of the mixture, you end up with

12.5 L - 2.5 L = 10 L milk, and

7.5 L - 1.5 L = 6 L water

Now you add 4 liters of milk. Now you have

10 L + 4 L = 14 L milk

6 L water

The new ratio of milk to water is 14:6 = 7:3

A triangle has vertices at a (2,4) b (4,3) c (5,7) which transformation would produce an image with vertices a' (-2,-4) b' (4,-3

zzz [600]

Answer:

180° rotation

Step-by-step explanation:

The triangle and its image are shown below.

The image is formed by a 180° rotation about the origin, every coordinate is inverted, that is, (x, y) ⟶ (-x, -y).

It is not formed by a 90° rotation or by a reflection across either axis.
