For the volume of a rectangular prism (box-shape), all we have to do is multiply, length * width * height.
We know from the text that the hole the construction company will be digging is 12 yards long, 7 yards wide, and 3 yards deep, so all we need to do to find the volume of the dirt removed in cubic yards is multiply, 12 * 7 * 3.

12 * 7 = 84

84 * 3 = 252

The construction company will have removed 252 cubic yards of dirt for the swimming pool.
Hope that helped! =)

Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices

Angelina_Jolie [31]

Answer:

The inequality is $0.75x\geq y$

Step-by-step explanation:

Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.

To find : Which inequality represents this situation?

Solution : He plays trumpet for a minimum of 45 minutes

$45 \text{minutes}=\frac{45}{60}=\frac{3}{4}=0.75\text{hours}$

If x is the number of days that Lionel practices then he practices for at least

$=0.75x$ hours

y is the total number of hours he spends practicing

So, the inequality form is:

$0.75x\geq y$

i.e, 0.75x is greater than y.
