Answer:

10.44

Step-by-step explanation:

First plot each of the points on to a graph at their respective positions.

Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)

You can then use the pythagorean theorem a^{2} +b^{2} = c^{2}.

Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation. 3^{2} + 10^{2} = c^{2}

Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 = c^{2} which in turn is 109 = c^{2}

Then take the square root of 109 to remove the square from the c to get c = 10.44

Which of the following is the method used to determine whether or not a proportion is true?
sdas [7]

Answer:

Cross multiplication is the method  used to determine whether or not a proportion is true.

Explanation:

If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.

Cross multiplication is the method used to determine whether or not a proportion is TRUE.

For example, if a bowl of fruit contains 10 oranges and 8 lemons, then the ratio of oranges to lemons is 10  is to 8 (that is, 10 : 8 ), which is equivalent to the ratio 5:4).

The sum of three numbers is 95. The first number is 5 more than the third. The second number is 4 times the third. What are the
kotykmax [81]

Answer:

20, 60, 15

Step-by-step explanation:

Let the third number be n, then

The first number is n + 5 and the second number is 4n

Sum the 3 numbers and equate to 95, that is

n + 5 + 4n + n = 95 ← collect like terms on left side

6n + 5 = 95 ( subtract 5 from both sides )

6n = 90 ( divide both sides by 6 )

n = 15

Thus

The first number is 15 + 5 = 20

The second number is 4 × 15 = 60

The third number is 15
