1 answer:

3 0

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=60\pi \end{cases}\implies 60\pi =2\pi r\implies \cfrac{60\pi }{2\pi }=r\implies 30=r$

denis-greek [22]

Answer:

D) Agile methodology

Step-by-step explanation:

Agile methodology can be described as a technique employed to to manage a project by a team whereby the project is divided into several stages and thereby necessitate the need for a constant collaboration among the stakeholders as well as continuous improvement and iteration at each of the stages of the project.

The description of the nature of the utilization of the end product and the definition of problem to be solved by the clients indicates the commencement of the agile methodology. The aim is to ensure the expectations of the clients are made clear to the project team.

After the commencement of the work, an incremental development process of planning, executing, and evaluating is constantly repeated by the teams with little emphasis on team coding and more emphasis one limiting the scope of the project so that the final deliverable of the project is altered with the sole aim of meeting the requirements of the customer better.

Therefore, the correct option is D, that is the agile methodology is an incremental development process that has less emphasis on team coding and more emphasis on limiting a project's scope.

If 0.142857142857......is expressed in the form m/n, then what is the value of (2m + n)?

frosja888 [35]

Answer:

The value will be: 1,285,713

Step-by-step explanation:

We have the number:

N = 0.142857...

Such that we have 6 decimals after the decimal point that repeat infinitely.

Then let's start by multiplying our number by 1,000,000 (same number of zeros as decimals after the decimal point)

Then we get:

1,000,000*N = 142,857.142857...

Now let's subtract N from both sides:

1,000,000*N - N = 142,857.142857... - 0.142857...

999,999*N = 142,857

Now let's isolate N

N = 142,857/999,999

Here is our number expressed in the form m/n, where:

m = 142,857

n = 999,999

Then the value of (2*m + n) is:

(2*142,857 + 999,999) = 1,285,713

8th Grade Functions: Bike Race

Arturiano [62]

Answer:

Juan wins the race

Step-by-step explanation:

The graph is shown in attached image.

The black line is Juan's graph.

The green line is Antonio's graph.

The graph shows the distance (y-axis) with time (x-axis).

The end of the curve(s) means the end of the race. Both curve's ending point in y-axis is 4 miles so the end of the race is 4 miles.

But in x-axis, we see the time:

Juan finishes at 13 minutes

Antonio finishes at 15 minutes

Definitely Juan wins the race
