Answer:
7.5 hours
Step-by-step explanation:
The key here is to find out how much can be done in the same amount ot time
the least common multiple of 5 hrs and 3 hrs is 15hrs
In 15 hours:
- At 5 hours per lawn Norton could mow 15/5 = 3 lawns
- At 3 hours per lawn together thay could mow 15/3 = 5 lawns
In 15 hours Jesse would mow 5 - 3 = 2 lawns
15 hours/ 2 lawns = 7.5 hours per lawn
7.5 hours
--------------------
Here's the math
1 lawn/5hrs + x = 1 lawn / 3hrs
1/5 + x = 1/3
Subtract 1/5 from both sides
x = 1/3 - 1/5
x = 5/15 - 3/15
x = 2/15
x = 2lawns/15 hrs
15hrs/2lawns = 7.5 hrs per lawn
7.5 hours
Answer:
A
Step-by-step explanation:
From the diagram:
- P(-4,6)→P'(4,6);
- Q(-7,4)→Q'(7,4);
- R(-6,1)→R'(6,1);
- S(-2,1)→S'(2,1);
- T(-1,4)→T'(1,4).
The general rule of this reflection is
(x,y)→(-x,y)
and this is reflection across the y-axis. The y-axis has the equation x=0.
I think there are more protests in modern day times rather then in the earlier time periods, because people are now more aware of their rights, and how they influence the way their country is run. Also, nowadays most countries are democratic, meaning that everyone can express their opinions and people protest as a way of expressing their opinions about something.
I think it’s the last one but I’m not sure
