What is the decimal expansion of the following fraction?
pickupchik [31]
You haven't shared a fraction.  Please do that next time.

I checked and have found that 0.045 repeating over the 4 and 5 is equivalent to 1/22.  Try dividing 1 by 22 to verify this.

So I infer that the fraction you haven't yet shared is 1/22.

Which statement most accurately describes Louisa’s error?
kolbaska11 [484]
For the options provided, the statement that most accurately describes federalism is number 3. Power is divided between the national government and the states. It is an arrangement of government in which a similar region is controlled by two levels of government. By and large, a general national government oversees issues that influence the whole nation, and littler subdivisions administer issues of nearby concern.





Hope this helps

If the endpoint is (3/2, 1 1/2), and the midpoint is (2/5, -8/5) what is the other endpoint
alukav5142 [94]

Answer:

The answer to your question is  ( -7/10, -4 7/10)

Step-by-step explanation:

Data

Enpoint (3/2, 1 1/2)                  x1 = 3/2     y1 = 1 1/2

Midpoint (2/5, -8/5)                xm = 2/5    ym = -8/5

Entpoint 2 ( x, y)

Formula

Xm = (x1 + x2)/2    Solve for x2    x2 = 2xm - x1

Ym = (y1 + y2)/2     Solve for y2   y2 = 2ym - y1

Substitution

                  x2 = 2(2/5) - 3/2

                  x2 = 4/5 - 3/2

                  x2 = (8 - 15)/10

                 x2 = -7/10

                  y2 = 2(-8/5) - 1 1/2

                 y2 = -16/5 - 3/2

                 y2 = (-32 - 15) / 10

                y2 = -47/10 = -4 7/10
