Which set of side lengths form a right triangle?

1 answer:

8 0

If you have a right triangle, you can use the Pythagorean theorem, which is a²+b²=c². (c is the longest side or the hypotenuse)

You plug in the shorter sides for a and b, then you square root the answer.

A 14m, 20m, 25m

14² + 20² = 25²

196 + 400 = 625

596 = 625 X

B 10cm, 6cm, 8cm

6²+8²=10²

36+64=100

100=100 So your answer is B

We have three coins: one with heads on both faces, the second with tails on both faces, and the third a regular one. We choose o

Answer:

Probability: $\frac{1}{2}$ = 0.5 = 50%

Step-by-step explanation:

Based on the question one coin is chosen at random and tossed. That coin then lands and is heads. Since the coin landed on heads we can eliminate the possibility of the coin that was chosen being the coin with double tails.

The following possibilities are that the coin has double heads or is a regular coin with both tails and heads. Seeing as the coin landed on heads, there are only two possible out comes for the other side of the coin

The other side is either Heads or Tails. That gives us a 50% chance of the other side being tails.

$\frac{1}{2}$ = 0.5 = 50%

Answer:

1 cm^2 : 9 m^2

Step-by-step explanation:

The scale factor of an area is the square of the scale factor of a length.

The scale for lengths is 1 cm : 3 m.

You now square that scale to get the scale of the areas.

Scale of areas:

(1 cm)^2 : (3 m)^2

1 cm^2 : 9 m^2
