A Web music store offers two versions of a popular song. The size of the standard version is

1 answer:

8 0

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!

What is the volume of this rectangular prism?

sergiy2304 [10]

Answer:

$V =\frac{12}{5}\ cm^3$

Step-by-step explanation:

The Volume of Rectangular Prism

Given a rectangular prism of dimensions W, L, and H, its volume is the product of the three dimensions:

V = WLH

The figure shows the dimensions:

L=3 cm

$W=\frac{4}{3}\ cm$

$H=\frac{3}{5}\ cm$

Thus, the volume is:

$V =3*\frac{4}{3}*\frac{3}{5}\ cm^3$

$V =\frac{36}{15}\ cm^3$

Simplifying:

$\boxed{V =\frac{12}{5}\ cm^3}$

How can you find the volume of a composed figure?

aliina [53]

The first composite shape is a combination of a rectangular prism and a pyramid. To find the volume of the entire shape you find the volume of each individual shape and add them together. The second figure consists of a cylinder and a hemisphere.

What is the answer to this question

timama [110]

Answer:

$b^6z^612a^5$

Step-by-step explanation:

The first step is to combine like terms, and multiply them together first. Since multiplication is commutative, it doesn't matter in what order you do it. Therefore, this can be rewritten as $(2a^2\cdot 6a^3)\cdot(b^4\cdot b^2)\cdot(z\cdot z^5)=(12a^5)\cdot(b^6)\cdot(z^6)=b^6z^612a^5$ . Hope this helps!
