Jack is mowing a lawn that has a shed,
Find the area of the lawn that jack has to mow.
The dimensions of the yard are 12x - 6 long and 7x wide.
The dimensions of the shed are 2x + 4 long and 4x wide.
Find a polynomial that describes the area of the lawn that needs to be mowed.
Step 1: Find the area of the lawn.
Step 2: Find the area of the shed.
Step 3: Find the area of the lawn by subtracting the shed area from the yard area.
Answer:
76x^2 - 58x
Step-by-step explanation:
Area of the Yard: 7x(12x-6) = 84x^2-42x
Area of the Shed: 4x(2x+4) = 8x^2+16x
Area of the Lawn: 84x^2-42x -(8x^2+16x) = (84x^2-8x^2) + (-42x-16x) =
76x^2 - 58x
The answer is "[tex]\bold{84x^2 - 42x, 8x^2 + 16x,\ and\ 76x^2 - 58x}[/tex]", and the further calculation steps can be defined as follows:
For step 1:
Calculating the lawn area:
[tex]\to \bold{7x (12x -6) = 84x^2 - 42x}[/tex]
For step 2:
Calculating the shed area:
[tex]\to \bold{4x( 2x + 4) = 8x^2 + 16x}[/tex]
For step 3:
Calculating the lawn area by subtracting the area of the shed from the area of the yard:
[tex]\to\bold{ 7x (12x -6) - (4x(2x+4))}\\\\\to\bold{ 84x^2-42x -(8x^2+16x)}\\\\\to\bold{ 84x^2-42x -8x^2-16x}\\\\\to\bold{ 76x^2-58x}\\\\[/tex]
So, the final answer is "[tex]\bold{84x^2 - 42x, 8x^2 + 16x,\ and\ 76x^2 - 58x}[/tex]".

Anna has a small business. Her mean revenue over the past 10 years is $85,000 with standard deviation of 2200. Anna earned 55% of her mean revenue by December 31, 2020. How much money does Anna want to have by year's end?
Answer:
$121,000
Step-by-step explanation:
Mean = $85000
Standard deviation = $2200
55% of mean revenue at the end of the year will be :
0.55 * $2200
0.55 * 2200
= $121,000
Hence, Anna wants to have $121,000 by year end

can someone solve this please?
Answer:
3.16 units
Step-by-step explanation:
The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex].
Let,
[tex] (6, 8) = (x_1, y_1) [/tex]
[tex] (7, 5) = (x_2, y_2) [/tex]
Plug these values into the distance formula.
Thus:
[tex] d = \sqrt{(7 - 6)^2 + (5 - 8)^2} [/tex]
[tex] d = \sqrt{(1)^2 + (-3)^2} [/tex]
[tex] d = \sqrt{1 + 9} [/tex]
[tex] d = \sqrt{10} = [/tex]
d = 3.16 (nearest tenth)
Distance between the two points in the graph is approximately 3.16 units

At the start of Kerin's diet he weighed 13 stone 12 pounds. Three months later he weighed 12 stone 10 pounds. There are 14 pounds in a stone. Calculate the reduction in Kerins weight as a percentage of his inetial weight.
Beginning of diet, 13 stone 12 pounds
13(14) + 12 = 194
Three months later, 12 stone 10 pounds
12(14) + 10 = 178
He lost 16 pounds in 3 months
I'm not really sure what the percentage would be, but it might be 16%

Hannah pays $27.50 for her dinner at her favorite restaurant in New York City. The cost of her dinner includes tax and tip, which was a 30% increase on the cost of her meal. What is the cost of Hannah’s meal without tax and tip?
Answer: $19.10
Step-by-step explanation:
To be honestly im not sure if this is 100% correct but, i did the work so it should be. So what i did was move the decimal from $27.50 one place to the left which is= 2.750. i then rounded the easiest number which then gave me the answer $2.80. Now the percentage, its 30% so you then change it to .30
then you multiply that number (.30 which is basically 3) with $2.80.
$2.80
x .30
--------
you then get $8.40
which is the total cost of tax AND tip.
you subtract that with the cost of the dinner. ( $27.50 - $8.40 ) and you get the answer $19.10! I hope this helps! :))

Eleanor Wotek took out a simple interest installment loan of $1,525 at 8 percent for 6 months. Her monthly payment on the loan is $260.17. After 3 payments, the balance is $769.98. If she pays off the loan when the next payment is due? a. What is the final payment? (2 points) b. How much is saved by paying off the loan early? (3 points)
Answer:
a. Final payment = $831.58
b. Amount saved = -$520.34
Step-by-step explanation:
a. What is the final payment? (2 points)
Interest element of fourth month payment = Principal balance after third month payment * 8% = $769.98 * 8% = $61.60
Final payment = Principal balance after third month payment + Interest element of fourth month payment = $769.98 + $61.60 = $831.58
b. How much is saved by paying off the loan early? (3 points)
Amount saved = (Monthly payment * 2 months) - Final payment = ($260.17 * 2) - $831.58 = -$520.34
Note:
The amount saved in part b above is negative i.e. -$520.34 which implies that Eleanor Wotek actually paid more instead of saving some amount.

Answer:
Father's shadow is 9 feet long.
Step-by-step explanation:
From the given figure,
ΔABC and PQR will be similar.
So their corresponding sides will be proportional.
[tex]\frac{AC}{PR}=\frac{BC}{QR}[/tex]
[tex]\frac{AC}{7.5}=\frac{6}{5}[/tex]
AC = [tex]\frac{6\times 7.5}{5}[/tex]
AC = 9 feet
Therefore, measure of the father's shadow is 9 feet.

Find the x values of x in the parallelogram
Answer:
No idea
Step-by-step explanation:
You need to show the parallelogram in order for your question to make sense.
Which figure represents the image of parallelogram
LMNP after a reflection across the line y = x?
o figure A
O figure B
o figure C
O figure D
The figure that represents the image of parallelogram LMNP after a reflection across the line y = x is figure C
How to determine the figure?From the graph, the coordinates of the parallelogram LMNP are:
L = (3,1)
M = (4,3)
N = (5,3)
P = (4,1)
When reflected across the line y = x, the coordinates become
L' = (1,3)
M = (3,4)
N = (3, 5)
P = (1, 4)
The figure with the above coordinates is figure C
Hence, the figure that represents the image of parallelogram LMNP after a reflection across the line y = x is figure C
