Step-by-step explanation:

2a + 2b + 2c

= (a + b) + (b + c) + (c + a)

= 5 + 6 + 7

= 18.

Hence, a + b + c = 9 and a = (a + b + c) - (b + c) = 9 - 6 = 3.

Which special version of the Pythagorean Theorem can you use to find the length of any squares diagonal, d, using only the lengt
EleoNora [17]

The square's diagonal is the triangle's hypotenuse.

The Pythagorean theorem is = a^{2}+b^{2}=c^{2}

Here, 'c' is the hypotenuse and 'a' and 'b' are the two sides of the triangle.

As the side is given 12 inches, so this becomes

12^{2}+12^{2}=d^{2}

144+144=d^{2}

d^{2}=288

d=\sqrt{288}

d=16.97 inches

If you flipped the coin 100 times, how many heads would you expect to get? Explain your answer.
Irina18 [472]

Answer:

You would expect to get 50 heads

Step-by-step explanation:

Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
