hector music teacher requires 450 min of practice each month. Hector practiced 239 min the first three weeks this month. Estimate how many minutes he has left to practice.
450 - 240 =
THANK YOU
You're welcome.
450-240=210minutes
So Hector needs to practice for 210 minutes or 3 hours and 30 minutes to be exact
To estimate how many minutes Hector has left to practice, we can calculate the total number of minutes he has practiced so far and subtract it from the required 450 minutes per month.
First, let's calculate how many minutes Hector has practiced in the first three weeks of the month. Since there are 4 weeks in a month, and Hector practiced for 3 weeks, we can use the following calculation:
Minutes practiced in 3 weeks = (Minutes practiced per week) x (Number of weeks)
= (239 min/week) x (3 weeks)
= 717 minutes
Now, we can calculate how many minutes Hector has left to practice:
Minutes left to practice = Required minutes per month - Minutes practiced in 3 weeks
= 450 minutes - 717 minutes
= -267 minutes
Based on the calculation, Hector has "negative" 267 minutes left to practice. This indicates that he has exceeded the required practice time.
