HELP PLEASE WILL THANK AND AWARD BRAINLIEST ANSWERGiven figure ABCD ~ figure KLMN, what is the value of y?

A.1.2 cm
B.3.6 cm
C.4 cm
D.12 cm

Answers

Answer 1

Answer: big trapezoid: upper base = 4 cm ; lower base = 12cm ; side = 10cm
small trapezoid: upper base = y ; lower base = ? ; side = 3cm

Figure ABCD is contracted into figure KLMN, this means that they have the same proportion as to the other sides of the figure.

side: 10 cm / 3cm = 3.33
upper base: 4cm / 3.33 = 1.20 value of y.
lower base: 12cm / 3.33 = 3.60

4/10 = 0.40 ; 1.20/3 = 0.40
4/12 = 0.33 ; 1.20/3.6 = 0.33
10/12 = 0.83; 3/3.60 = 0.833

Write an counter example for the statement: all square roots are rational numbers

Answers

That is not true. For example, if you take PI . Rounded is 3.14. But if you were to do the square root of pi then it would be an IRRATIONAL number. so it's false.

It's false because if you take the square root of a decimal number or a complex number, you're sure to find an irrational number.
