Part A: Find a rational number that is between 7.7 and 7.9. Explain why it is rational. (2 points)
8_murik_8 [283]
A rational number is any number that can be written as the ratio between two other numbers i.e. in the form \frac{a}{b}

Part A:
An easy choice that makes sense is 7.8, right in the middle. To prove that it's rational we need to write it as a ratio. In this case we have 7.8=\frac{78}{10}

Part B:
We need a number that can't be written as a ratio (because it neither terminates nor repeats). Some common ones are \sqrt{2}, e, \phi and \pi so it makes sense to try and use those to build our number. In this case \frac{11\sqrt{2}}{5}\approx7.78 works nicely.

The length of a rectangle is 12 in. and the perimeter is 56 in. Find the width of the rectangle.
yuradex [85]

Answer:

W = 16 in

Step-by-step explanation:

P = 2L + 2W

56 = 2(12) + 2W

56 = 24 + 2W

56-24 = 2W

32 = 2W

W = 32/2

W = 16 in

Best regards
