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

Steps to solve:

3(5 - x) > -15

~Distribute

15 - 3x > -15

~Subtract 15 to both sides

-3x > -30

~Divide -3 to both sides

x < 10

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 The money deposited is held by the institution and can be withdrawn at a later time.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.

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

Step-by-step explanation:

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

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

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

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

[tex](x-3)^2=5[/tex]

Solving:

[tex]x-3=\pm \sqrt{5}[/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.

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.

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.

Answer: m = 10 h

Step-by-step explanation: i did the test too

The Equation for Rachel Earning is m = 10h.

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

Simply divide to get the value

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 following absolute value inequalities are used to determine if a scale factor (k) is an expansion or a contraction.

So, 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.

[tex]0 > |3/4| > 1[/tex]

[tex]0 > |0.75 | > 1[/tex]

Remove absolute brackets

[tex]0 > 0.75 > 1[/tex]

[tex]0 > |1/5| > 1[/tex]

[tex]0 > |0.2| > 1[/tex]

Remove absolute brackets

[tex]0 > 0.2 > 1[/tex]

Hence, 3/4 and 1/5 are all contraction scale ratios

*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).
