Answer:

30

Step-by-step explanation:

80 + 40 = 120

120 represents the total students for all 4 classes. And since there is an even amount in each class...

120 / 4 = 30

So 30 would be your answer.

Can anyone help me with these two questions

Hi there!

The linear equation would be y = 3x + 11. This is because the slope is 3, found by using the formula (y2-y1 / x2-x1). Then, we can plug in the slope and a point into y=mx+b form. Next, we can plug in 0 for x and 0 for y to figure out if the line goes through the point (0,0). Doing this, we discover that the line does not go through the point (0,0).

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

The library at school is organized by fiction and non-fiction books. There are 3 non-fiction books for every 7 fiction books. Ho
sweet [91]

Answer:

Total = 800 books

Step-by-step explanation:

It is given that,

In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.

There if the library has 240 non-fiction books.

Let non fiction books are 3x and fiction books are 7x.

ATQ,

3x=240

x=80

Fiction books = 7x = 7(80) = 560

Total no of books = fiction books + non-fiction books

= 240 + 560

=800

Hence, the total no of books are 800.

1. A quadrilateral has vertices (5, 3) (5,-1) (-1,3) and (-1,-1). What special quadrilateral is formed by connecting the midpoin
antiseptic1488 [7]

Answer:

1. Kite,

2. Kite.

Step-by-step explanation:

1. The quadrilateral form will have 2 equal  pairs of adjacent sides which is a kite.

2. Find the slope and length of the sides:-

slopes (9-6)/ 0-3) = -1

(6-1) / (3-0) = 5/3

(6-1) / (-3-0) = -5/3

(9-6)/(3) = 1

Lengths = sqrt(9 + 9) = sqrt18

sqrt(25 + 9) = sqrt34

sqrt (25 + 9) = sqrt34

sqrt (9 + 9) = sqrt18.

This is another kite.

Answer:

=  {x}^{ - 11}  {y}^{ - 11}  {z}^{ - 10}

Step-by-step explanation:

= \frac{ {x}^{ - 9} {y}^{ - 5}   {z}^{ - 7} }{ {x}^{2}  {y}^{6} {z}^{3}  }  \\   = {x}^{ - 9 - 2}  {y}^{ - 5   - 6}  {z}^{ - 7 - 3}  \\  =  {x}^{ - 11}  {y}^{ - 11}  {z}^{ - 10}
