Let L = Length, and W = Width. We are given the fact that L = 2W, and also know that the area = L x W = 50 square feet. So, by substitution: 2W x W = 50 sq ft, or 2W^2 = 50 sq ft, so W = sq rt (50/2) = 5 ft. Now, L = 2W = 2(5) = 10 ft. The perimeter of the fence is given by: 2L + 2W = 2(10 ft) + 2(5 ft) =20 ft + 10 ft = 30 ft. So, Ben needs 30 ft of fencing.
No rob is incorrect because 8+8 equals 16 9+9 also equals 18 so they odds and even could make an even product
Answer:
Step-by-step explanation:
The water has to be 100% - 60% = 40%
100% represents both water alcohol (I think that's what you meant).
40% of 250 = 40/100 * 250 = 10000/100 = 100 mL
So 100 mL = water
150 mL = alcohol.
For this one your answer is -309
