Answer:

A 846 square inches

Step-by-step explanation:

Use the net:

Rectangle 1: (21 in + 3 in + 21 in + 3 in) by 15 in.

Rectangle 2: 21 in by 3 in

Rectangle 3: 21 in by 3 in

total area = sum of areas of 3 rectangles above.

total area = (48 in * 15 in) + 2(21 in * 3 in)

total area = 720 in^2 + 126 in^2

total area = 801 in^2

Answer: A 846 square inches

Can I please get help?

Parallelogram:
just multiply 16 by 30.
The area is 480.
Semicircles:
Since there are 2 semicircles, they can be merged to one circle.
The area of a circle is πr²
The diameter is 28, so the radius is 14.
Substitute and solve.
π14²
π196 ≈ 615.8
Now add 615.8 with 480
Your answer is 1,095.8 units squared.

A Web music store offers two versions of a popular song. The size of the standard version is
sashaice [31]
Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations: 
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads: 
s = 280
Hope this helps!
