Olive buys indie music online. Each song costs $2 plus a $5 fee for using the artist's site. She has no more than $40 to spend.
mina [271]
First, set a variable.

Let x = the number of songs bought.

Each song costs 2 dollars. So, we have our first term: 2x.
And there is a fee of 5 dollars for using the website.

2x + 5

And she can't spend any more than 40 dollars. Which means she can spend 40 and under.

So, 2x + 5 ≤ 40 is the answer.

If the cube above has a surface area of 54cm^3, what is the volume of the cube?
Colt1911 [192]

9514 1404 393

Answer:

  27 cm³

Step-by-step explanation:

The surface area of a cube is ...

  SA = 6s²

Then the edge length is ...

  54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area

  9 cm² = s² . . . . . .divide by 6

  3 cm = s . . . . . . . take the square root

The volume of a cube is ...

  V = s³

  V = (3 cm)³ = 27 cm³

The volume of the cube is 27 cm³.

AysviL [449]
<span>The interquartile range is the difference between the third quartile and the first quartile. First, find the median so you can separate the data in half. The median is the middle number. Arrange the numbers from least to greatest and find the number in the middle.

</span>\sf 24, 25, 27, 36, 37, 42, 42, \boxed{\sf 43}, 49, 49, 50, 53, 59, 61, 65

Find the medians of these two halves. These will be Quartile 1 and Quartile 3.

\sf 24, 25, 27, \boxed{\sf 36}, 37, 42, 42

Quartile 1 is 36

\sf 49, 49, 50, \boxed{\sf 53}, 59, 61, 65

Quartile 3 is 53

\sf IQR=Q3-Q1=53-36=\boxed{\sf 17}
