tangare [24]

Answer:

  see below

Step-by-step explanation:

The definition of a parallelogram is that opposite sides of the quadrilateral are parallel. Felice already knows one pair of opposite sides is parallel. By showing the slope of RQ is the same as the slope of ST, she can show the other pair of opposite sides is parallel, hence the figure is a parallelogram.

How many 8's are in the answer and sum 5890/45?
Novay_Z [31]

Answer:

  • <em><u>1. There are infinite 8's</u></em>
  • <em><u>2. The estimate is 130.89</u></em>
  • <em><u>3. The difference is 0.01</u></em>

<em><u /></em>

Explanation:

There are countless, or infinite, 8's in the answer because the result is a periodic decimal:

        \dfrac{5890}{45}=130.8888 . . .

The notation used for the periodic decimal numbers is an arc over the number that is repeated. In this case, it would be an arc over the first 8.

I will use a bar just to show how it is, but instead of a bar it should be an arc:

          \dfrac{5890}{45}=130.\overline 8

The <em>estimation</em> or approximation to <em>two decimal places</em> requires to drop the 8's since the third one and increase the second 8 to 9 (because the first decimal dropped is greater than or equal to 5).

Thus the estimated value would be 13.89.

The difference is:

  • 130.89 - 130.888. . . = 0.0111. . .
  • Rounded to 2 decimal places: 0.01
