Answer:

678

2

679

Step-by-step explanation:

Number of people: 5426

Capacity of table: 8

How many tables are full?

  • Number of full tables= 5426/8= 678.25 so full part is 678

How many people are sitting at a table that is not full?

  • 0.25 table= 8*0.25= 2 people are sitting at a table that is not full

or

  • 5426 - 678*8= 2 people

How many tables are needed for all 5,426 people?​

  • 678+1= 679 tables

Help! It says that I need to determine If both equations represent lines which are parallel, perpendicular, or none...
12345 [234]
    4x + 2y = 8     (1)
    8x + 4y = -4y  (2)

A) Two lines are parallel if they have the same gradient
       - putting both equations into the gradient- intercept form ( y = mx + c                where m is the gradient)
            (1) 4x + 2y = 8
                          2y = 8 - 4x
                            y = -2x + 4
             
            (2) 8x + 4y = -4y
      <span>                    </span>8x = -4y - 4y
                            y = \frac{-8x}{-8}
                            y = -x
   <span>Thus the gradient of the two equations are different and as such          the two lines are not parallel
</span>
B)  When two lines are perpendicular, the product of their gradient is -1
                   m_{1} * m_{2} = p
                                             p = (-2) * (-1)
                                             p =  2
<span>          ∴ the two lines are not perpendicular either.</span>

Thus these lines are SKEWED LINES

<h2 />

Step-by-step explanation:

\frac{5}{9}  \div 5

  • <u>dividing</u><u> the</u><u> </u><u>equivalent</u><u> </u><u>to </u><u>multiplying</u><u> </u><u>by </u><u>the </u><u>reciprocal</u>

<u>\frac{5}{9}  \times  \frac{1}{5}</u>

  • <u>reduce </u><u>the </u><u>numbers</u><u> </u><u>with</u><u> the</u><u> </u><u>gr</u><u>e</u><u>atest </u><u>common </u><u>factor</u><u> </u><u>5</u>

<u>=  \frac{1}{9}  \:  \: \\  \\ or \:  \: in \:  \: alternate \:  \: form \\  \\ 0.1, {3}^{ - 2}</u>
