The formula of the area of a square is the side length squared. So to get the width of the rectangle, you need to square root the area of the square. The square root of 256 is 16, therefore the width of the rectangle is also 16 inches. Since the length of the rectangle is 2 inches longer, you add 2 to 16, which gives you 18 inches.

The formula for the area of a rectangle is the length multiplied by the width.

18*16=288. The area of the rectangle is 288 inches.

The answers are A and D.
The numbers that you cannot simplify without having a radical in the answer are irrational numbers. 

√(4/16) = 1/4 or -1/4, rational number
√(9/16) = 3/4 or -3/4, rational number
√(9/4) = 3/2 or -3/2, rational number

√(3/16) = √(3)/4, NOT a rational number, cannot remove radical
√(3/4) = √(3)/2, NOT a rational number, cannot remove radical

Find all solutions to each quadratic equation
romanna [79]
I hope this helps you



2x^2-4x+7=0 a=2 b=-4 c= 7



disctirminant =b^2-4ac


disctirminant =(-4)^2-4.2.7


disctirminant = 16-56= -40


x=-b+square root of disctirminant ÷2a


x=4+2square root of (-10)/4


x=2+square root of (-10)/2


x'=4 -2 square root of (-10)/4


x'=2 -square root of (-10)/2

(a) If you toss 10 coins, what percent of the time will you get the three most likely macrostates (6 heads and 4 tails, 5 heads
FromTheMoon [43]

This question is incomplete, the microstates table is left out which will be uploaded along this answer;

Answer:

a) the required is 65.6%

b) the required time is 4.2666 hrs

Step-by-step explanation:

using the microstates from the table in the diagram;

a)

the percent times the above any of the above microstates occurs is;

% (6 heads and 4 tails, 5 heads and 5 tails, 4 heads and 6 tails)

=   ((210 + 252 + 210)/1024) × 100

= 0.6562 × 100

= 65.6%

Therefore the required is 65.6%

b)

the probability of getting 10 heads and 0 tail or 0 tail head and 10 tails is;

p( 10H, 0T or 0H, 10T = 2/1024

= 1/512

so on average, it will take 512 trails or at a rate of 2 trials/min, 256 mim in hours;

(256 min) ( 1h/60min) = 4.2666 hrs

Therefore the required time is 4.2666 hrs
