Answer:

[tex]\frac{211}{500}[/tex]

Step-by-step explanation:

[tex].4\bar{2}[/tex]  means the 2 repeats till infinity
[tex].4\bar{2}[/tex]  = .4222222222.....

To convert to fraction just take the first three decimal place digits 422 and divide by 1000 to convert to fraction

[tex].4\bar{2} = \frac{422}{1000}[/tex]

Dividing numerator and denominator of this fraction by 2 gives
[tex]\frac{422/2}{1000/2} =\frac{211}{500}[/tex]

This cannot be simplified further and therefore
[tex].4\bar{2} = \frac{211}{500}[/tex]

If we had chosen first 4 decimal digits then it would be[tex].4\bar{2} = \frac{4222}{10000} = \frac{2111}{5000}[/tex]
i.e. we divide by 10,000

The amount the restaurant needs to earn on Sunday to average $1000 per day over the three-day period is $819.

What is average ?

The average is the ratio of the sum of the number of a given set of values to the total number of values present in the set.

It is given that restaurant earns $1073 on Friday and $1108 on Saturday.

The amount which restaurant needs to earn on Sunday to average $1000 per day over the three-day period can be calculated by finding the average.

The average is given by ratio of sum of amount on each day from Friday to Sunday and divide it by number of days.

Let's assume amount earn on Sunday is $x.

So ,

[tex]\frac{1073 + 1108 + x}{3}[/tex] = 1000

1073 + 1108 + x = (1000 × 3)

2181 + x = 3000

Let's solve this equation to get the value of x.

x = 3000 - 2181

x = $819

So , amount earn by restaurant is $819.

Therefore , the amount the restaurant needs to earn on Sunday to average $1000 per day over the three-day period is $819.

The following equation  [tex]y=\frac{-2x}{3}+2[/tex]  represents the given line.

An equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=3x+1. Where:

a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex].

b= the constant term that represents the y-intercept.

For solving  linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.

For the given example: a=3 and b=1

The question gives:

Thus, you can write from the question information :

y=ax+b

0= -2/3*(3)+b

0= -2 + b

b=2

Now, you know the value of the slope and the constant term.

Therefore, the standard form for the linear equation is:

Through a telescope, the diameter looks 9,000 μm long.

magnification scale  used was 450:1

A scale factor is a number that can be used to adjust the size of any geometrical figure or object in relation to its original size. It's used to draw the enlarged or reduced shape of any given figure, as well as to calculate the missing length, area, or volume of an enlarged or reduced figure. It should be noted that the scale factor only affects the figure's size and not its shape.

A scale factor is a number or conversion factor used to adjust the size of a figure without changing its shape. It is used to enlarge or reduce the size of an object. If the dimensions of the original figure and the dimensions of the dilated (increased or lowered) figure are known, the scale factor can be determined. A rectangle, for example, has a length of 5 units and a width of 2 units. If we raise the size of this rectangle by a factor of two, the sides will become 10 and 4, respectively. As a result, we can use the scale factor to determine the dimensions of the altered figures.
