Answer:
C
Step-by-step explanation:
A. is wrong because having a different height for each seedling and not trying to keep it equal is simply worse than making sure the heights are identical.
B. Completely wrong because it would likely result in 1 plot having more melon seedlings than the other.
C. Correct because it makes sure the seedlings are the same height at the beginning of the experiment, allowing less randomness in the experiment.
D. Putting the taller of a each pair for 1 plot makes it the experiment rigged in favor of the plot with taller seedlings
E. Same issue as D.

77 < answer
Step-by-step explanation:
The total time taken by Clem Shirestock to reach the gate is given by the equation 7 = 4√(x²+1)+ 8 - 2 x
Let the point P is at a distance of x miles from the toll gate.
Hence when Clem reaches the point P he rows in the form of right angled triangle. and we know that the width of the river is 1 mile.
So by using Pythagoras Theorem we can infer that the distance covered by Clem is the hypotenuse which is equal to √(x²+1).
Time taken to complete this route is 4√(x²+1) .
Now he has only to walk 4-x distance along the river.
His speed is 2 mph
Time taken = 2(4-x) = 8-2x
Hence we can conclude that the total time is 7 hours. so the equation to represent this is 7 = 4√(x²+1)+ 8 - 2 x .

Answer:
1) 27/128 ft³
2) 40cm³
Step-by-step explanation:
1) The diagram is a cuboid not a prism.
Volume of the shape = Length × Breadth × Height
Given the following dimension
Length = 3/8 ft
Breadth = 3/4 ft
Height = 3/4 ft
Volume = 3/8 × 3/4 × 3/4
Volume of the shape = 27/128 ft³
2) Volume of a rectangular prism = Base Area × Height
Given base area = 12cm²
Height of the prism = 3 1/3 cm
Volume = 12 × 3 1/3
Volume = 12 × 10/3
Volume = 4 × 10
Volume of the prism = 40cm³
