Given area of square field =0.25 hectare
1 hectare =10,000m =0.25×10,000 =0.25×100 =2500 sq. m
Let side of square be 'a'
Area of square =a 2 a 2 =2500 ⇒a=50m
Diagonal of square = 2 a= 2 ×50=50 2 ​ m.

Answer:

155.56m

0.242 hectares

Step-by-step explanation:

L=\frac{220}{\sqrt{2} } =155.56m

A=\frac{155.56^{2}}{10^{5} }  =0.242

how is it possible for the expected value of a game to be losing 65 cents of the only outcomes are win $2 or lose $1
Stells [14]
Let x be the probability of winning and let y be the probability of losing. Then we can write the following equation:
2x - y = -0.65 ..............(1)
the sum of the probabilities of winning and losing must equal 1.
x + y = 1............(2)
Rearranging (2), gives:
y = 1 - x ............(3)
Plugging the expression for y from (3) into (1), we get:
2x - 1 + x = -0.65
which simplifies to:
3x = 0.35
Therefore x = 0.117 and y = 0.883.
The expected value of the game will be a loss of 65 cents if the probability of winning is 0.117 and the probability of losing is 0.883.

Which values of m and b will create a system of equations with no solution? Select two options.
natima [27]

Using linear function concepts, a system of equations with no solutions is created when:

m = -2, b \neq \frac{3}{2}

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The intersection of two lines is the solution of a system of equations. If two lines have the <u>same slope and different intercepts</u>, they will never intercept, that is, the system will not have a solution.

The lines are given as follows:

  • y = mx + b.
  • y = -2x + 3/2.

Hence, for a system with no solution, we need that:

m = -2, b \neq \frac{3}{2}
