Answer:
136 ft of woods
Step-by-step explanation:
1. Let us assume that we are solving for the frame of the deck alone
2. And also from the given parameters the deck has a rectangular shape
we know that the total amount of woods to be used is same as the perimeter of the rectangle.
Given that
length l= 60 ft
width w= 8 ft
The formula for the perimeter of a rectangle is given as
Perimeter= 2l+2w
perimeter= 2*60+ 2*8
perimeter= 120+16
perimeter= 136 ft
Hence in other to construct the frame of the deck Adam needs a total of 136 ft of woods
As soon as a new car that costs $25,000 $ 25,000 is driven off the lot, it begins to depreciate at a rate of 24.9% 24.9 % annually. About how much money is the car worth after the second year?
Answer:
14,100.03 (just finished a test with this question and got it correct)
The car is worth about $14,100.03 after the second year.
What is the depreciation rate?The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.
If a car depreciates at a rate of 24.9% annually, then its value at the end of each year is 75.1% of its value at the beginning of the year (100% - 24.9% = 75.1%).
After the first year, the car's value is:
$25,000 × 0.751 = $18,775.00
After the second year, the car's value is:
$18,775.00 × 0.751 = $14,100.03
Therefore, after the second year, the car is worth about $14,100.03.

Parallel lines are always coplanar. Perpendicular lines are always coplanar and, Distance around an unmarked circle can never be measured.
What are parallel and perpendicular lines?Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.
1. Parallel lines are always coplanar.
When two lines are parallel to each other it means that the two lines will never intersect each other and their plane is also the same.
2. Perpendicular lines are always coplanar.
From the definition that two lines will be perpendicular to each other their angle should be 90 degrees or they should intersect at 90 degrees angle to each other.
3. Distance around an unmarked circle can never be measured.
We need to have a marked circle to measure the distance. So, the distance from the centre of the circle to one point of it is the radius. Moreover, the distance between two points of the circle taking a line passing through the centre is the diameter of the circle.

Barry's savings account has a balance of $2874. After 9 years, what will the amount of interest be at 5% compounded annually? a. $1589.52 c. $1575.52 b. $1584.52 d. $1437.00 Please select the best answer from the choices provide
Answer:
b. $1584.52
Step-by-step explanation:
To find the answer, first you have to find the amount that you will have after 9 years using the formula to calculate the future value:
F=P*(1+i)^n, where
F= future value
P= present value= $2874
i= interest rate= 5%
n= number of periods of time= 9
Now, you can replace the values in the formula:
F=2874*(1.05)^9
F= 4458.52
Then, as you know the value that you will have after 9 years, you can subtract the initial balance from this, to find the amount of interest:
$4,458.52-$2,874= $1,584.52
According to this, the answer is that the amount of interest at 5% compounded annually would be $1,584.52.

HELP I NEED AN EXPLANATION IM CONFUSED |3x|>-12 is x>−4 or x<4 but I dont know how that is. I thought it was no solution.. can someone explain.
Answer:
see below (I hope this helps!)
Step-by-step explanation:
|3x| > -12
There are two cases, x is either positive (in which |3x| = 3x) or negative (in which |3x| = -3x). Therefore:
3x > -12 or -3x > -12
x > -4 or x < 4 (Remember, multiplying / dividing an inequality by a negative number flips the sign.)
Answer:
All real numbers.
Step-by-step explanation:
So we have the equation:
[tex]|3x|>-12[/tex]
Remove the absolute value bars. Definition of absolute value:
[tex]3x>(-12)\text{ or } 3x<-(-12)[/tex]
Note that we change the sign on the right because we multiplied by a negative.
Divide both sides by 3:
[tex]x>-4\text{ or }x<4[/tex]
Now, look at this inequality. This says that the solution is all the numbers to the right of -4 and all numbers to the left of 4.
I've provided a number line. The red line represents x>-4 and the blue line represents x<4.
As you can see, every value is covered both towards the left and the right.
In other words, our answer is all real numbers.

What is the area of the figure composed of a parallelogram, a square and a rectangle ?
Answer : The area of the figure composed of a parallelogram, a square and a rectangle is 126 in².
Step-by-step explanation :
Area of composed figure = Area of parallelogram + Area of square + Area of rectangle
First we have to calculate the area of parallelogram.
Area of parallelogram = Base × Height
Given:
Base = 10 in
Height = 3.5 in
Area of parallelogram = 10 in × 3.5 in
Area of parallelogram = 35 in²
Now we have to calculate the area of square.
Area of square = (Side)²
Given:
Side = 4 in
Area of square = (4 in)²
Area of square = 16 in²
Now we have to calculate the area of rectangle.
Area of rectangle = Length × Breadth
Given:
Length = 12.5 in
Breadth = 6 in
Area of rectangle = 12.5 in × 6 in
Area of rectangle = 75 in²
Now we have to calculate the composed figure.
Area of composed figure = Area of parallelogram + Area of square + Area of rectangle
Area of composed figure = 35 in² + 16 in² + 75 in²
Area of composed figure = 126 in²
Therefore, the area of the figure composed of a parallelogram, a square and a rectangle is 126 in².
The area of the given figure is 126in²
Composite figuresThe given figure is a composite figure composed of a parallelogram, a square and a rectangle.
Get the area of the square
Area = L²
Area of the square = 4² = 16in²
Area of the rectangle = 6 * 12.5
Area of the rectangle = 75in²
For the parallelogram:
Area of the parallelogram = Base * Height
Area of the parallelogram = 10 * 3.5
Area of the parallelogram = 35 in²
Area of the figure = 75in² + 35in² + 16in²
Area of the figure = 126in²
Hence the area of the figure is 126in²

Step-by-step explanation:
So we have the rational expression:
[tex]\frac{-12a^3b^5}{4a^2b^7}[/tex]
In rational expressions, the restrictions of the expression would be the zeros of the denominator Therefore, set the denominator equal to zero and solve for its zeros:

Zero Product Property:
[tex]4a^2=0\text{ or } b^7=0\\[/tex]
Solve for a and b:

F.If you get pulled over for speeding, the ticket will cost $50 for each mile over the speed limit.
The independent variable is the miles over the speed limit, and the dependent is the cost
The cost relies on the number of miles over the speed limit
G.You are starting a garden and already bought the pots for $25.
Each flower you buy costs $3.50
The independent is the number of flowers purchased, the total cost is the dependent
The cost is dependent on the number of flowers purchased
H.Your grandmother is knitting you a blanket. She already made the blanket 5 inches long. Each hour she knits, the blanket gets 0.8 inches longer.
The independent is the hours knitted, the dependent is the length of the blanket
The length will depend on how long she knits

Answer:
[tex]d+0.5c+2r=8\\\\ c=2d[/tex]
Step-by-step explanation:
Let d= dramas
c= comedies
r= reality shows
Dramas are 1 hour long, comedies are 30 minutes, and reality shows are 2 hours long.
Total time spent on watching = [tex]1 \times(d) + 0.5 \times (c) +2 \times(r)= d+0.5c+2r[/tex]
[ [tex]30\ minutes=\dfrac{30}{60} \ hours = 0.5 hour \ \ (1 hour = 60\ minutes)[/tex] ]
Since he spent 8 hours for this, that means
[tex]d+0.5c+2r=8[/tex] → First equation
He watches twice as many comedies as dramas.
i.e. [tex]c=2d[/tex] → second equation
So, the system of equations could be used to determine how many of each type of show he watches each week:
