Let W and L be width and length of the rectangular pen respectively.
Therefore,
Circumference, C = 2W+2L= 130 yd
Area, A = LW = 1050 yd^2=> L = 1050/W
Using the circumference expression and substituting for L;
130 = 2W + 2(1050/W) = 2W+2100/W
130*W = 2W*W + 2100
130W = 2W^2 +2100
2W^2-130W+2100 = 0
Solving for W;
W= [-(-130)+/- Sqrt ((-130)^2-4(2)(2100)]/2*2 = 32.5+/- 2.5
W = 30 or 35 yd
When W = 30, L = 1050/30 = 35
When W = 35, L = 1050/35 = 30
Therefore, W = 30 yd and L = 35 yd.
Answer:x=-2
Step-by-step explanation:
You want to set up the equal to zero
Then add six to both sides
Then divide by -3x
Answer:The difference between the medians is 2.5
Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5
3 cm = 24 miles
2.5 cm = 20 miles
8 cm = 64 miles
12 cm = 96 miles
4.5 = 36 miles
To find miles and cm just use a multiplication chart of 8 and with the decimals, just multiply it with 8.
EX:
2.5 • 8 = 20
The y-intercept is (0, 2), because it's the spot where the line crosses the y-axis. The other point showed on the graph is the x-intercept..
