Answer:
Step-by-step explanation:
We have to find out the area of the square in order to find how many square inches were cut from the squared cloth.
Diameter = 42 in.
Radius = D / 2 = 42 / 2 = 21 in.
Area of circle = πr²
Where r = 21 in.
Area = (3.14)(21)²
Area = (3.14)(441)
Area of the circle = 1385.4 in.²

The true option is: (d) <em>Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?</em>
The inequality is given as:
Rewrite as:
From the options, we can see that the inequality represents songs in a music player.
Linear inequalities can be represented as:
Where:
m represents the rate i.e. 10
b represents the y-intercept or base i.e. 15
>= represents at least
So, the inequality can be interpreted as:
- 10 songs are added every month
- The base number of songs is 15
- He wants to have at least 135 songs
Hence, the true option is (d)
