Which of the following sets contain only rational numbers?

Answer:

Step-by-step explanation:

The relationship that exists between the length of the hypotenuse and the length of the legs is that the sum of both of the legs lengths squared is equal to the hypotenuse length's squared or in other words, the Pythagorean theorem.

Power Rule.

15\log(0.0176471)=t\log(.5)

Answer:

Answer may be c+18=6

Step-by-step explanation:

If you reverse the equation to 18/3 you will get 6

Given that △ABC and △DBE are similar triangles, the length of DB is: 25

The ratio if the corresponding sides of two triangles that are similar are the same, meaning, their sides are proportional.

Given that:

Thus:

Let DB = x

Therefore:

BD/BA = BE/CB

Substitute

x/(x + 5) = 10/12

Cross multiply

12x = 10x + 50

12x - 10x = 50

2x = 50

x = 25

Therefore, given that △ABC and △DBE are similar triangles, the length of DB is: 25

Step-by-step explanation:

Answer:

√a² = |a|

Step-by-step explanation:

√a² = |a| not a

because the amount of "a" can be negative and when it reaches power 2 the minuse sign converts to plus sign , so we must use absolute value : |a| . notice that the answer never can be negative.

example:

a = -2

√(-2)² = √+4 = |-2| = 2 -2

Answer:

Step-by-step explanation:

First sequence : 10,9.5,9,8.5,...

Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5

So on and so on. So, the common difference between these numbers are 0.5

Next sequence : 200,100,50,25, ...

We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.

200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25

So on and so on. So, the common ratio of these numbers are 1/2.

Answer:

Step-by-step explanation:

A common difference is the number you need to get from a chosen number on your left to get to the next number going right.

In the first sequence, you start with 10 on your left.

To get to the next number going right, you need to subtract 0.5 or add - 0.5

In any event, the common difference is -0,5

The second problem is a little  harder. It does not follow the same sort of pattern that the first question does. This time you are multiplying or dividing.

200 * 1/2 = 100

100 * 1/2 = 50

50 *  1/2 = 25

25 *  1/2 = 13.5

So the common ratio is 1/2

Answer:

There are 60 seconds per minute.

a) 270 seconds,

270 seconds/60 seconds (a single minute) = 4 minutes and 30 seconds

60 goes into 270, 4 times so that's 4 whole minutes with a remainder of 30 seconds.
