Answer: No, it is not a right triangle.

Explanation:
9^2 + 7^2 (?) 12^2

81 + 49 (?) 144

130 = 144

Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.

3: Mary has 26 sweets and is able to share them evenly between her friends.
Alexxx [7]

Answer:

Mary has 12 friends, and a total of 13 people including her. Or, she has 25 friends, and a total of 26 people including her.

Step-by-step explanation:

First, we know that 26 is divisible by 1, 2, 13, and 26 because (2x13) and (1x26) both equal 26 but we know that Mary has more than 1 friend and if Mary is also added to the group where the candy is divided, that means that 1 and 2 are both out because Mary has more than 1 friend so 1 cannot be the answer and if Mary has 2 friends, that means that the candy would have to be divided 3 ways which is not possible evenly so the answer is either 12 friends or 25 friends.

Eduardo counted ten seconds (y) between seeing lightning and hearing thunder, and he knew that the lightning was about 2 miles (
Fed [463]

Answer:

The equation for the variation is:

\frac{Miles}{thunder\,\,time }  =0.2\,\frac{mi}{s}

Step-by-step explanation:

The relationship is given by the quotient between the two variables: (1) distance of the storm, and (2) the number of seconds to hear the thunder. That is:

\frac{Miles}{thunder\,\,time } =\frac{2}{10} =0.2\,\frac{mi}{s}
