Assuming the rectangles made will be of the same size:
Perimeter = 2(l + b)
For two rectangles,
Perimeter = 2 x 2(l + b)
240 = 4(l + b)
l + b = 60
l = 60 - b
Area = l x b
Area = 60b - b²
dA/db = 60 - 2b
Putting dA/db = 0
b = 30
Length = 60 - 30 = 30
Greatest available area of one triangle = 30 x 30
= 900 sq yd
Greatest total area that can be enclosed in both triangels
= 900 x 2
= 1800 sq yd
The next larger hundredth is xxxx.31 .
The next smaller hundredth is xxxx.30 .
xxxx.307 is nearer to xxxx.31 than it is to xxxx.30 .
So 4,124.31 is the nearest hundredth.
Answer - c </= 4 or c >/= -3
2c - 1 </ 7
2c - 1 + 1 </= 7 +1
2c </= 8
2c/2 </= 8/2
c </= 4
2c - 1 >/= - 7
2c - 1 + 1 >/= -7 + 1
2c >/= -6
2c/2 >/= -6/2
c >/= -3

Step-by-step explanation:
Answer:
0.4
Step-by-step explanation:
If the ratio of boys to girls in a class is 2:3, then
- there are 2x boys;
- there are 3x girls.
If there are 18 girls in the class, then
Thus, there are
boys;
girls;
students in total.
The probability of a boy being in the class is
