Answer:
The answer is D.
Step-by-step explanation:
It is given that Gabriella swims 2 laps for 1 minute. So in order to find how many minutes did he swim for each lap, you have to divide it by 2 :
2 laps = 1 minute
2 laps ÷ 2 = 1 minute ÷ 2
1 lap = 1/2 minute
= 30 seconds
Test :
Gabriella swim 1/2 min per lap. So if he swim 2 laps, you have to multiply it by 2 :
1/2 × 2 = 1 minute
Answer:
A = 3.14
Step-by-step explanation:
A = π
A = 3.14 x 
(diameter = 2)
(remember, radius is half of the diameter)
(radius = 1)
A = 3.14
The domain tells you about the independent variable, number of payments made. So the inequality should be
smallest number of payments made ≤ variable representing payments ≤ largest number of payments made.
The smallest number of payments is 0 and the largest is 8, so you'll have

<u>Description</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>Randomized</u><u> </u><u>block design</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>experiment</u><u> </u><u>:</u>
Randomized block design involved the divison of subjects into units, called block. After which treatment are randomly applied to elements or subjects in each block.
Here, we make divide the 30 mature trees into 3 which means we have <em>3 blocks of 10 mature</em> trees each. The citrus <em>fertilizers A, B and C</em> are then applied randomly to each of the three units.
B.)
The randomized block design used in these experiments will correct for the possible error which could be introduced die to systematic error since each of the treatments(fertilizers A, B and C) would be used in each of the blocks.

Answer:
1) 36 yard
2) 2 feet
Step-by-step explanation:
1) Perimeter = 4 * side length
144 = 4 * s
s = 36
2) Area = Length * Length
4 = l * l
l = 2
