When two rays are put together it forms an angle (because of the three points)

myrzilka [38]2 years ago

Sample Response: An angle is defined as two rays with a common endpoint, so CAB (or BAC) is an angle. A line is described as an infinite set of points that extend forever in either direction, which these rays also do.

mauricio estimates that the first module of the project could be completed in as few as 15 days or could take as many as 25 days

4vir4ik [10]

Answer:

Most likely time, according to PERT (Program evaluation and review technique).

Step-by-step explanation:

PERT is "a statistical tool used in project management" (Program evaluation and review technique (2020), in Wikipedia), and it is commonly used with CPM (Critical Path Method) to manage projects.

Inside PERT, there are different defined times to accomplished an activity in a project, that is:

An optimistic time or minimum time required to accomplished an activity, i.e., if everything goes better than normal, the activity is accomplished before expected.
A pessimistic time, a time quite the opposite to optimistic time.
A most likely time, or a time required to accomplished an activity if everything goes as expected or normally.
An expected time, an statistical estimation.

Considering the question, we have that the time when "the first module of the project could be completed":

"[...] in as few as 15 days" is the optimistic time.
"[...] or could take as many as 25 days" is the pessimistic time.
"[...] but most likely will require 20 days" is the most likely time.

As a result, the 20-day estimate is called the most likely time in the context of the PERT/CPM techniques.

What is the perimeter of a square whose diagonal is 13.010

miskamm [114]

The perimeter would be ≈ 36.797836892947.

Rounded would be about 37, or 36.8.

Hope this helps!!!!

$P=4a$

$d\sqrt{2a}$

Solving for P:

$P=2\sqrt{2d} =2*\sqrt{2*13.01}$ ≈36.79784

Hope this helps!!

What is side Bc round to nearest hundredth

neonofarm [45]

Answer:

BC = 15.01

Step-by-step explanation:

Solve this question using a trigonometry ratio, which you can remember them all with SohCahToa, which says:

sinθ = opp / hyp

cosθ = adj / hyp

tanθ = opp / adj

θ means the "angle of reference" (angle we are talking about).

In this problem, θ is A = 65°,

To decide which trig. ratio to use, find out which sides we want to use. We will use AC = 7 because we know it.

We also use BC because we need to find it.

In relation to ∠A or θ, AC is adjacent and BC is opposite.

The ratio with adjacent and opposite is tangent.

tanθ = opp / adj Substitute the variables for this question

tanA = BC / AC Substitute the values you know

tan65° = BC / 7 Rearrange this and isolate C

BC = 7tan65° Multiply 7 and tan65 to find the missing side

BC = 15.011548...... Exact answer on your calculator

BC ≈ 15.01 Round to nearest hundredth

In a slight hurry thanks for all the help!

julsineya [31]

Answer:

10.

Step-by-step explanation:

AK = KB so

3x + 1 = 1/3 x + 9

3x - 1/3 x = 9 - 1 = 8

Multiply through by 3:

9x - x = 24

8x = 24

x = 3

So AK = 3(3) + 1 = 10.
