Blueberries cost $1.78 per pound. What is the cost of 1.05 pounds of blueberries? Round your answer to the hundredths. You will not grid the dollar sign.
Answer:
Approximately $1.87 ($1.869)
Step-by-step explanation:
There are 2 ways to do it
1.78 x 1.05 = 1.869 / $1.87
Or
1.78 x .05 = .089
1.78 + .089 = 1.869 / $1.87

A new set of apple airpods cost $250 calculate the new price if you got a 20% discount and the sales tax 8%
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

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.
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) 1/4x^2
(B)2/5x^2
(c) 1/2x^2
(D) x^2
(e) 20
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

how do i solve this?
Answer:
y = 6
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

(25 Points)
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.
