Marco is limited to 7 hours of screen time each week. he decides to watch a movie that is 1 hour and 20 minutes on sunday. if he
1 answer:
Marco can watch TV for at most 56 minutes each day.
Step-by-step explanation:
Given,
Time of screen each week = 7 hours
1 hour = 60 minutes
7 hours = 60*7 = 420 minutes
Length of movie = 1 hour + 20 minutes = 60 + 20 = 80 minutes
Time left for other days = 420 - 80 = 340 minutes
Number of days = 6
Let,
x be the time per day for remaining 6 days.
Number of days * Time per day ≤ Time remaining
Dividing both sides by 6
Marco can watch TV for at most 56 minutes each day.

Answer:Perry and Lorna take the maximum time and Maria and Lorna take the minimum time when they work together.
Explanation: Since, according to the question- Perry takes time when he works alone = 3 hours
Similarly, Maria takes = 2 hours, While Lorna takes= 2 hours 30 minutes or 2.5 hours.
since, there are three people thus their are three possibility to choose any two of them.
1- when Perry and Maria work together then time taken by them is =
= 6/5= 1 hour 12 minutes.
2- when Maria and Lorna work together then time taken by them is = 10/9= 1 hours 1/9 minutes ≈ 1 hours 7 min
3- when Perry and Lorna work together then time taken= = 15/11= 1 hour 4/11 minutes≈ 1 hours 21 minutes
From the above explanation, it has been proved that when we talk about 2 members team then Perry and Lorna take the maximum time. While Maria and Lorna take the minimum time when they work together.
Answer:
Distance from point (0,1,1) to the given line is zero.
Step-by-step explanation:
Given parametric equations of line,
x=2t, y=5-2t, z=1+t
To find distance from (0,1,1), we have to eliminate t from above equations so that,
whose direction ratioes are (l,m,n)=(3,2,-2) and distance fro point (a,b,c)=(0,1,1) is given by,
Distance between point (0,1,1) and (1) is zero. That is point 90,1,1) is lies on the line (1).
