A certain reality TV show lost 9,000 viewers over the past 3 months.If they lost the same number of viewers each month how many viewers did they lose each month
Answer:
3,000 viewers each month.
Step-by-step explanation:
1. they lost the same amount each month, which means you can divide the viewers lost by the number of months (3)
2. that would be 9,000/3
3. 3,000
4. You know you've got the right answer because this would multiply back to 9,000 with the same amount of viewers lost every month.

[tex]x^2-6x+4=0[/tex]

[tex]x=3 \pm \sqrt{5}[/tex]
An equation is formed when two equal expressions. The equation by completing the square can be rewritten as (x-3)²=5.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given equation can be rewritten in the equation form by completing the square as,
x² - 4x + 4 = 2x
Bring the like terms on the same side of the equation,
x² - 4x - 2x + 4 = 0
Simplify the like terms of the equation,
x² - 6x + 4 = 0
Add positive 5 to both sides of the equation,
x² - 6x + 4 + 5 = 5
Solve the like terms,
x² - 6x + 9 = 5
Using the binomial property (a-b)²=a²+b²-2ab, x² - 6x + 9 can be written as,
(x - 3)² = 5
Hence, the equation by completing the square can be rewritten as (x-3)²=5.

In 3 years, Dianna will be 4 times as old as she was 33 years ago. How old is Dianna now?
Answer:
45 yrs old
Step-by-step explanation:
x + 3 = 4(x - 33)
:x + 3 = 4(x) - 132
Add 132 and minus x on both sides of equation
then: 135 = 3(x)
Answer:
Present age of Dianna is 45 years old
Step-by-step explanation:
Let "x" be the present age of Dianna
Given that, In 3 years, Dianna will be 4 times as old as she was 33 years ago
Then: In three years time Diana’s age would be x + 3
And: thirty three years ago it would have been x - 33
From given question,
x + 3 = 4 times as old as she was 33 years ago
x + 3 = 4(x - 33)
x + 3 = 4x - 132
x - 4x = -132 - 3
-3x = -135
x = 45
Thus present age of Dianna is 45 years old
Rachel’s has a summer job working at the library. The graph below shows the relationship between the number of hours Rachael worked and the amount of money, in dollars, that Rachel earned?
Answer: m = 10 h
Step-by-step explanation: i did the test too
The Equation for Rachel Earning is m = 10h.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
From the graph we take two points (4, 35) and (5, 45).
So, the slope is
= (45 - 35) / (5-4)
= 10 /1
= 10
let Rachel work for h hours then Rachel earned

On Dolores's tenth birthday her grandfather deposited $35 in a savings account for her. Each year, her grandfather deposited twice the amount of the previous year's deposit. How much money did her grandfather deposit on Dolores's eighteenth birthday?
Her grandfather deposits $28,680 on Dolores's eighteenth birthday.
What is a deposit?
A deposit is an amount of money that is placed into an account, typically a savings or checking account, with a financial institution such as a bank or credit union. The money deposited is held by the institution and can be withdrawn at a later time. Deposits can also refer to the act of putting money into an account.
In your example, on Dolores's tenth birthday her grandfather deposited $35 in a savings account for her. Each year, her grandfather deposited twice the amount of the previous year's deposit. On Dolores's eleventh birthday, the deposit was 352 = $70. The deposit for twelfth birthday was 702 = $140. Similarly, on Dolores's 18th birthday, the deposit was 35*2^8 = $28,680.
Hence, her grandfather deposits $28,680 on Dolores's eighteenth birthday.

A square garden has an area of 1604 square feet. Approximately how long
is each side of the garden?
Answer:
102 sq. ft.
Step-by-step explanation:
In order to find the side lengths, we divide 1604 by 2. Since it's a square, each side is the same length. Area is length times width so we only need two sides.
1604÷2=102

Classify each scale factor as a contraction or an expansion. Drag and drop the choices into the boxes to complete the table. Contraction Expansion 1.25 -2 3/4 1/5 3
Scale factor 1.25 is an expansion since we 'enlarge' the original size 1.25 times
Scale factor 3 is an expansion since we 'enlarge' the original size by 3 times
Scale factor -2 is also an expansion since we 'enlarge' the original size by 2 times but on the opposite direction of the centre of enlargement
Scale factor 3/4 is a contraction since we make the original size 'smaller' by 0.75 times
Scale factor 1/5 is also a contraction since we make the original size 'smaller' by 0.20 times
Literally, contraction means to reduce; while expansion means to increase.
The scale factors that represent contraction are 3/4 and 1/5The scale factors that represent expansion are 1.25, -2 and 3The following absolute value inequalities are used to determine if a scale factor (k) is an expansion or a contraction.
[tex]|k | > 1[/tex] represents expansion[tex]0 < |k | < 1[/tex] represents contractionSo, we have:
The absolute value of 1.25, -2 and 3 are greater than 1. i.e.
[tex]|1.25| > 1[/tex]
Remove absolute brackets
[tex]1.25 > 1[/tex]
[tex]|-2| > 1[/tex]
Remove absolute brackets
[tex]2 > 1[/tex]
[tex]|3| > 1[/tex]
Remove absolute brackets
[tex]3 > 1[/tex]
Hence, 1.25, -2 and 3 are all expansion scale ratios
The absolute value of 3/4 and 1/5 are between 0 and 1. i.e.

*the box plots are shown in the attachment below.
Answer:
The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both.
Step-by-step explanation:
Median on a box plot is depicted by the vertical line that divides the rectangular box into 2.
The median hours for school 1 = 8
The median hours for school = 9
Interquartile range on a box plot is the range of the rectangular box.
Interquartile range for school 1 = 10 - 4 = 6
Interquartile range for school 2 = 12 - 6 = 6
Therefore, it is true that the median hours spent by school 1 (8 hrs) is less than the median hours spent by school 2 (9 hours).
It is also true that the jnterquartile range for school 1 and school tok are also equal (6).
