Answer: c. 8 cm, 15 cm, 22 cm

Step-by-step explanation:

The triangle inequality says that for any triangle, the sum of the lengths of any two sides must be greater than to the length of the remaining side.

a. 22 cm, 5 cm, 10 cm

Here $5+10$

Thus these can not be the lengths of the sides of a triangle.

b. 11 cm, 6 cm, 17 cm

Here $6+11=17$

Thus these can not be the lengths of the sides of a triangle.

c. 8 cm, 15 cm, 22 cm

Here, $8+15>22$

$22+15>8\\22+8>15$

Thus these three lengths can be the lengths of the sides of a triangle.

d. 6 cm, 22 cm, 10 cm

$6+10$

Thus these can not be the lengths of the sides of a triangle.

Rupert is copying some files from his computer to a compact disc, like the one shown above.

My name is Ann [436]

Option B: $11,304 \mathrm{mm} ^2$ is the area of the compact disc.

Explanation:

The diameter of the compact disc is $120mm$ .

To determine the area of the compact disc, let us substitute the values in the area of the circle formula,

$A=\pi r^2$ where $r=\frac{d}{2}$

Substituting the value of d in $r=\frac{d}{2}$ , we get,

$r=\frac{120}{2} =60$

Thus, $r=60$ and $\pi=3.14$ . Let us substitute these values in $A=\pi r^2$ , we get,

$A=3.14\times(60)^2$

Simplifying, we have,

$A=3.14\times3600$

Multiplying, we get,

$A=11304mm^2$

Thus, the area of the compact disc is $11,304 \mathrm{mm} ^2$

Hence, Option B is the correct answer.

A web store offers two versions of a popular song. The size of a standard version is 2.9 MB. The size of the high-quality versio

olasank [31]

Answer:

This problem is a great systems of equations problem--you have two different variables: song size and number of songs.

Let's call the number of standard version downloads (S) and the high quality downloads (H).

You can make two statements:

For number of songs downloaded: S + H = 910

For download size: 2.8(S) + 4.4(H) = 3044.

S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:

2.8(S) + 4.4(910 - S) = 3044

2.8S + 4004 - 4.4S = 3044

-1.6S = -960

s = 600

Your question only asks for the standard version downloads, but to help you out in future Systems situations-

You can also solve for H once you have S by plugging it into either of your equations like this:

600 + H = 910

-600

H=310
