Answer:

85% of the job is finished.

Step-by-step explanation:

The way to find the percentage is to divide 119 by 140, which will come out to be .85.

If you roll a six sided die what is the p(5)? Express your answer as a fraction and as a percent.
hodyreva [135]

When rolling one die, there is one "5" outcome and six total outcomes. The formula for probability is represented as:

P(A) = \dfrac{\textrm{number of outcomes resulting in} \,A}{\textrm{total number of outcomes}}


Thus in this case, to find P(5), we would go about the following:

P(5) = \dfrac{1}{6}


To convert \frac{1}{6} to a percent, we first multiply by 100 and then divide, as shown:

\dfrac{1}{6} \cdot 100 = \dfrac{100}{6} = 16.\overline{6} \,\%


The fraction would be 1/6 and the percentage would be 16.666...%, which is often rounded to 16.67%.

Please help on B C D ONLY PLEASE
Rama09 [41]

The answer for B is: 40 - (7.50 x 4) = 10 Because 7.50 x 4 = 30 and 40 - 30 = 10 So they are left with $10 after paying for the tickets

The answer for C is: Miguel and his 3 friends started with $40 and had a fee of $7.50 for each ticket and there are 4 people. 4 x 7.50 = 30 and 40 - 30 = 10 so they are left with $10 to spend on snacks and other stuff!

Idk the answer for D sorry about that!

Hope this helps!
