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.

The height of a painting is 48 ronded ft. Between which two consecutive whole numbers is 48 rounded

Karolina [17]

Answer:

47 and 49

Step-by-step explanation:

This would not be between two consecutive whole numbers. Any number from 47.5 and less than 48 would round up, and any number from 48 to less than 48.5 would round down. It might be consecutive odd numbers that you meant, or your question is not clear enough.
