Why are (1,2) and(2,1) not equal ordered pair? ​

Answer:

The pairs ( 1 , 2 ) and ( 2 , 1 ) are not equal because their respective elements are not equal.

Step-by-step explanation:

The pair of elements which are in specific order is called an ordered pair. The pair ( 1 , 2 ) is not same as the pair ( 2 , 1 ). In the pair ( 1 , 2 ) 1 is in the first position and 2 is in the second position. In the pair ( 2 , 1 ), 2 is in the first position and 1 is in the second position.

Two ordered pairs ( a , b ) and (c , d ) are said to be equal if a = c and b = d. We write ( a , b ) = ( c , d ).

Hope I helped!

Best regards!!

The two shortest sides of a right triangle are 10 in. And 24 in. long. What is the length of the shortest side of a similar righ
ivanzaharov [21]
If the two shortest sides of the triangle are 10in and 24in, then using Pythagoras' theorem, the longest side =
\sqrt{10^2 + 24^2} 
= \sqrt{676}
= 26

Now we know the two longest sides of the first triangle (24in and 26in) we can compare them with the two longest sides of the second triangle.
If x = the scale factor the first triangle is enlarged by then
26x = 39 and 24x = 36 
⇒ x = 1.5

Finally, we need to multiply the smallest side of the first triangle by the scale factor to find the shortest side of the second triangle.
10(1.5) = 15
So the length of the shortest side of the other triangle is 15in.

You could, instead, calculate the length of the shortest side of the second triangle by using Pythagoras' theorem and ignoring the first triangle completely.

Which of the following are solutions to the equation below? Check all that apply. 9x^2-64=0
nikdorinn [45]

Answer:

E. -8/3

F. 8/3

Step-by-step explanation:

9x^2-64=0

Add 64 to each side

9x^2-64+64 = 0+64

9x^2 =64

Divide each side by 9

9x^2/9 = 64/9

x^2 = 64/9

Take the square root of each side

sqrt(x^2) = ±sqrt(64/9)

We know that sqrt(a/b) = sqrt(a)/sqrt(b)

x = ±sqrt(64)/sqrt(9)

x = ± 8/3

1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2)<br> what is v?
Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

1 \frac{1}{2} \\  =  \frac{2 \times 1 + 1}{2}  \\  =  \frac{3}{2}

In order to find the value of v, you have to substract 3/4 to both sides :

\frac{3}{2}  = v +  \frac{3}{4}

\frac{3}{2}  -  \frac{3}{4}  = v +  \frac{3}{4}  -  \frac{3}{4}

v =  \frac{3 \times 2}{2 \times 2}  -  \frac{3}{4}

v =  \frac{6}{4}  -  \frac{3}{4}

v =  \frac{3}{4}
