1. The formula for calculate the perimeter of a rectangle, is:
P=2L+2W
P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.

2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W
3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:
P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet
4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:
x=P-W
x=320 feet-40 feet
x=280 feet
<span>
How many linear feet of fence must he buy?
</span>
The answer is: 280 feet
It will take her 34 weeks. I got this answer because 10% of $450 is $45. Since she borrowed $1500, you divide $1500 by $45. You get 33.333... Since you earn per week, that rounds up to 34 weeks.

Answer:
277 848 newspapers.
Step-by-step explanation:
Find out how much newspaper he drops for 4.3 miles.
1/4 = 0.25
4.3 miles ÷ 0.25 = 17.2
= 17
17 x 22.7 = 385.9
(Newspapers be dropped a day)
1 week of dropping newspapers = 385.9 x 3 = 1157.7
1 month of dropping newspapers = 1157.7 x 4 =
4630.8
1 year = 12 months
5 years = 12 x 5 = 60 months.
5 years/60 months of dropping newspapers = 4630.8 x 60 = 277 848
Tommy dropped 277 848 newspapers.
For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.
Answer:
4. 3
Answer:
A
Step-by-step explanation:
If lines are parallel and intersected by another line then there are 2 alternating angles between them.
