I have a square piece of paper. Square has all equal sides (each side was 10 cm and there were 4 sides) I fold square A in half to make rectangle B. I fold rectangle B in half to make square C. a) what is the perimeter of rectangle B? b) what is the perimeter of square C?

two sides of square c times those to each other

Step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
