-11.3 is rational or irrational ? explain? 0.083 and 2.1371938 to please if its not much to ask?
zloy xaker [14]
Ignore the - sign for now.   11.3   =   11.3        113
                                                         -------  = ----------
                                                             1             10

Since this is the ratio of two integers, 11.3 is rational.  So is 11.3.

                                                                             83
If you really mean   <span>0.083, this is rational:  it is ---------
                                                                            1000

If y ou meant </span><span>0.083333333 ... , that's also rational:  1/12 is equivalent.</span>

In a triangle, the measure of one angle is five more than the first and the third angle is one more than four times the first.
katrin [286]

Answer:

A= 29

B=34

C=117

Step-by-step explanation:

<u>A triangle has three sides and a triangle always adds up to be 180</u>

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

<u>Now since you found A, find the other two by plugging A in!</u>

C = 4(29) + 1

C = 117

<u>Plug in the B equation</u>

B = 29 + 5

B=34

Check your answers

29 + 117 + 34 = 180

a long board 4.7 thick is cut into three pieces of equal length these three pieces are then stacked the stack is cut in three eq
nalin [4]

The number of pieces per stack after 3 cuts represented by a power expression can be written as 3^{3}

  • The number of equal pieces per cut = 3

  • The number of cuts made = 3

<u>Using a power </u><u>expression</u><u> </u><u>:</u>

  • The number of of equal pieces per cut is raised to a power which represents the number of cuts made

  • Thus we have number\: of \:equal\: pieces^{number\: of \:cuts}

  • After 1 cut ; 3^{1} = 3
  • After 2 cuts ; 3^{2} = 3\times3 = 9
  • After 3 cuts ; 3^{3} = 3\times3\times3 = 27

Therefore, the Number of pieces present in stack after 3 cuts is 3^{3}

So what you do is multiply 60, 30, and 100 together to get 180,000. Then divide 180,000 by 18,000 (simplify it to 180 ÷ 18) and the answer is 10. So they could turn it up 10 notches.
