What integer is equivalent to 9 and 3 halves
sweet [91]

Answer:

6 is the integer which is equivalent to 9 and 3 halves

Step-by-step explanation:

we have to find the integer which is equivalent to 9 and 3 halves

Rule of halves means the restatement of meaning of median. Therefore, we have to find the median of these two integers 9 and 3.

Median of 9 and 3 is \frac{9+3}{2}=\frac{12}{2}=6

Hence, 6 is the integer which is equivalent to 9 and 3 halves

Lia wants to find the sum of 17, 51, 10 and 13. Show two different ways that Lia could find the sum of these numbers.
Alekssandra [29.7K]
Since addition is commutative, she can add anyway she wants.
(17+51)+(10+13)
(51+10)+(17+13)
Hope this helps.

What is the distance between 4-i and -2+3i?
stepan [7]
If you're working with complex numbers, then I'm sure you're comfortable with plotting them on a complex-plane ... real part of the number along the x-axis, and imaginary part of the number along the y-axis.

When you look at it that way, your two points are simply two points on the x-y plane:

           4 - i    ===>  (4, -1)

         -2 + 3i  ===>  (-2, 3) .

The distance between them is

                       D  =  √ (difference in 'x')² + (difference in 'y')²

                           =  √  (6)² + (4)²

                           =  √ (36 + 16)

                           =   √ (52)

                           =      7.211  (rounded)

please help me evaluate this. the answer is B but im not sure how to get the answer without using a calculator. please show step
iragen [17]

Answer:

  b.  9/100

Step-by-step explanation:

It helps if you have memorized the cubes of small integers. Of course, the ones needed here are ...

  3³ = 27

  10³ = 1000

The desired value can be simplified to ...

  \left(-\dfrac{1000}{27}\right)^{-2/3}=\left(-\sqrt[3]{\dfrac{3^3}{10^3}}\right)^2=\dfrac{(-3)^2}{10^2}=\dfrac{9}{100}
