1/3 chance of getting a cracked egg
Answer:
For the rectangle
Length=ℓ
Breadth=b
Area is 12 cm2
ℓb=12
Perimeter is 16 cm
2(ℓ+b)=16
ℓ+b=8
Substitute b=12ℓ from first equation
ℓ+12ℓ=8
ℓ2+12=8ℓ
ℓ2−8ℓ+12=0
Use quadratic formula (x=−b±√b2−4ac2a) to find ℓ
ℓ=−(−8)±√(−8)2−(4×1×12)2×1
ℓ=8±√162
ℓ=8±42
ℓ1=8+42=6
ℓ2=8−42

Well, the diameter doesn't matter in this problem because we allready know how fast, and how much the pool is filling. So, 6 inches is half of a foot, because 1 foot = 12 inches, and six is half of 12. If it take 1 hour for the pool to fill 1/2 of an foot, than it takes 2 hours for a full foot. Next, we multiply 2 hours, by 1 foot, and convert the 1 foot, to 4 feet. Which means to figure out the number of hours, we have to times 2 hours by 4 feet. And that is 8.
So the answer is: 8 feet.

Answer:
F=$3810
Step-by-step explanation:
F= future value
P= present value
i = interest
n= number of times money compounded
P=$3000 i=6% n = 2 X 4= 8
As this is semiannual so 6%/2=3%
