Since, a rectangle with a diagonal of length x is twice as long as it is wide, the area of the rectangle is (B) 2x²/5
How to find the area of the rectangle?Given that we have a rectangle with a diagonal of length x is twice as long as it is wide.
Let
L = length of rectangle, W = width of rectangle and D = length of diagonal = xGiven that the length of diagonal, x is twice as long as it is wide, we have that
L = 2W
Also, since it is rectangle, we have that
D² = L² + W²
D² = (2W)² + W²
D² = 4W² + W²
x² = 5W²
W² = x²/5
W = x/√5
W = x√5/5
Since the length of the rectangle, L = 2W, we have that
L = 2W
= 2x√5/5
The area of the rectangleThe area of the rectangle is given by A = LW where
L = length of rectangle and W = width of rectangleSo, A = LW
= 2x√5/5 × x√5/5
= 2x² × 5/25
= 2x²/5
So, the area of the rectangle is (B) 2x²/5

Step-by-step explanation:
We find the stationary point of (20 + 2x)(1200 - 60x),
where x is the unit rate of increase/decrease.
d/dx [(20 + 2x)(1200 - 60x)]
= d/dx (-120x² + 1200x + 24000)
= -240x + 1200.
When d/dx [(20 + 2x)(1200 - 60x)] = 0,
We have -240x + 1200 = 0. => x = 5.
Price per shirt that maximise revenue
= $20 + $2x = $20 + $2(5) = $30.
Maximum revenue
= (20 + 2(5))(1200 - 60(5))
= $30 * 900 = $27,000.

The area of a newspaper page (opened up) is about 630.92 square inches. Determine the length and width of the page if it’s length is about 1.22 times its width.
Answers
X x Y = 630.92 inches
Replace X with 1.22Y
Which looks like this
1.22Y x Y = 630.92 inches
Now get Y by itself
Y x Y = 630.92/1.22
Y squared= 630.92/1.22
Y= the square root of 630.92/1.22
Y= 22.74 inches
X= 22.74 x 1.22
X= 27.74 inches
Multiply X and Y to check your answer equals 630.92 inches

The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches.
What is a rectangle?
The rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Lets say,
Length of newspaper = l
Width of newspaper = w
Area of newspaper ( rectangle ) = l × w
Now,
Length is about 1.22 times its width.
So,
l = 1.22w
By substituting
1.22w × w = 630.92
1.22w² = 630.92
w² = 517.147
w = 22.74 inches
So,
l = 1.22 × 22.74
l = 21.52 inches
Hence "The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches".

A new set of apple airpods cost $250 calculate the new price if you got a 20% discount and the sales tax 8%
Answers
Answer:
$216
Step-by-step explanation
We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.
250 * 0.8
This will give us 200.
Now, we need to add the sales tax which is 8%.
Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.
200 * 1.08 = $216

Step-by-step explanation:
You solve by using the pythagorean theorem, which is:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Where a and b are legs of the triangle, and c is the hypotenuse, or y in this case. So let's rearrange this equation for c:
[tex]c=\sqrt{a^{2} +b^{2} }[/tex]
Now, we can substitute in the known values and solve:
[tex]c=\sqrt{3.6^{2} +4.8^{2} } = \sqrt{36} = 6[/tex]
Therefore, the value of y is 6
