Is 1 = 2 always a false statement?
lutik1710 [3]

Answer:

yes, 1 can never equal 2 unless it is manipulated (ex: 1(2) = 2)

because one is not being manipulated to equal 2 here, it is a false statement and will always be a false statement.

the coordinates of a line segment are (1,6) and (11, -4). what is the length of the line segment? round your answer to the neare
ddd [48]
The length of the line segment AB where A(x_A;\ y_A) and B(x_B;\ y_B)

|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}

We have: A(1;\ 6);\ B(11;-4)

subtitute

|AB|=\sqrt{(1-11)^2+(6-(-4))^2}=\sqrt{(-10)^2+10^2}=\sqrt{100+100}\\\\=\sqrt{100\cdot2}=\sqrt{100}\cdot\sqrt2=10\sqrt2\approx14.1

Answer: b. 14.1

Answer:

30 degrees

Step-by-step explanation:

Let Angle ABC be 2x, Angle EBC be 5x

angle \: dbc = 90 - 2x \\ angle \: dbc \:  + angle \: ebc = 180 \\ 90 - 2x + 5x = 180 \\ 3x = 90 \\ x = 30 \\  \\ angle \: dbc = 90 - 60 \\   = 30

Michael’s haircut was 14.00 he gave a tip of 3.50 what percentage did Michael leave as a tip
Maurinko [17]

Answer:

D. 25%

Step-by-step explanation:

There are two ways that I do this. Both of them are probably not what your teacher tells you, but hey, I got the right answer.

The first method is to go through the answers and do 14 x .10, 14 x .20, and so on until you get 3.50.

The second method is to do 14/3.5, which equals 4. This means 14 can be broken up into 3.50 four times. So, 3.50 is 1/4 of 14. What is 1/4 of 100%? 25%.
