Find the diagonal of a square whose sides are of the given measure. Given = 6sqrt2
jeyben [28]

Answer:

=12 units

Step-by-step explanation:

When a square is cut along one diagonal, it forms a right angled triangle whose legs are the sides of the square and the hypotenuse is the diagonal of the square.

Therefore, the Pythagoras theorem is used to find the hypotenuse.

a² + b² = c²

(6√2)²+(6√2)²=c²

72+72=c²

c²=144

c=√144

=12

The diagonals of the square measure 12 units each.

Fiesta28 [93]

Answer:

3/5

Step-by-step explanation:

30 + 40 + 15 + 15 = 100

40/100 will be green

100/100 - 40/100 = 60/100

60/100 will NOT be green

60 ÷ 5 = 12

100 ÷ 5 = 20

12 ÷ 4 = 3

20 ÷ 4 = 5

strojnjashka [21]

Answer:

\boxed{0.2}

Step-by-step explanation:

Convert \dfrac{12}{60} to a decimal

Step 1. Reduce the fraction to its lowest terms.

Divide both numerator and denominator by their greatest common factor (12)

\dfrac{12}{60} =\dfrac{1}{5}

Step 2. Convert the denominator to a power of 10

Multiply both numerator and denominator by 2.

\dfrac{1}{5} \times \dfrac{2}{2} = \dfrac{2}{10}

Step 3. Divide the numerator by the denominator

Dividing by 10 moves the decimal point one place to the left.

\dfrac{2}{10} = \boxed{0.2}
