<h3>Answer:</h3>

c) 7π cm

<h3>Step-by-step explanation:</h3>

The length of an arc (s) is related to its central angle (θ) and the radius of the circle (r) by ...

... s = rθ . . . . . . . . . θ in radians

Here, the central angle measures are given in "grads". There are 400 grads in a circle, so 200 grads in π radians. To convert grads to radians, we multiply the number of grads by π/(200g).

Then the lengths of the arcs are ...

... arc AB = (20 cm)·(50g·(π/(200g))) = 5π cm

... arc BC = (10 cm)·(40g·(π/(200g))) = 2π cm

E = arc AB + arc BC = 5π cm + 2π cm = 7π cm

If a baseball player get a hit in 31% of his at-bats, what is the probability that he will
solong [7]

Given:

A baseball player get a hit in 31% of his at-bats.

To find:

The probability that he will  get a hit 5 at-bats in a row.

Solution:

Since, a baseball player get a hit in 31% of his at-bats, therefore

Probability that he get a hit = \dfrac{31}{100}

                                           = 0.31

Now, the probability that he will  get a hit 5 at-bats in a row is

P=0.31\times 0.31\times 0.31\times 0.31\times 0.31

P=(0.31)^5

P=0.0028629151&#10;

Therefore, the required probability is (0.31)^5 and it can be written as 0.0028629151 .

How do I find miles per hour when I get minutes and miles
Scilla [17]
In this case you have:

\frac{miles}{minute}

An hour has sixty minutes.

\frac{60 minutes}{1 hour}

<span>You must multiply by this equality.

</span>(\frac{miles}{minute})(\frac{60 minutes}{1 hour})=\frac{(miles)(60 minutes)}{ (minute)(hour)}=\frac{(miles)(60)}{(hour)}


<span>You must multiply by 60 and you can convert miles per minute to miles per hour.</span>

A company makes 3 types of cable. Cable A requires 3 black, 3 white, and 2 red wires. B requires 1 black, 2 white, and 1 red. C
harina [27]

Answer:

The answer is (B) but with 2 as the last item in the matrix, instead of 1.

Step-by-step explanation:

The grand topic is MATRICES.

In Matrices, there are rules to follow when creating a matrix - which is a 'row by column' arrangement of objects or figures.

Rule 1: Identify your rows and columns.

What is a row? A row is a 'left to right' arrangement of items; also called a horizontal arrangement of items. What is a column? A column is an 'up to down' arrangement of items; also called a vertical arrangement of items.

Rule 2: Start your arrangement by rows.

Before reaching the instruction in the question, I already arranged the data for cables on the rows and the data for wire colors on the columns. You should follow this rule always; from the first information given in the question.

Rule 3: Nomenclature

This is the naming of a given matrix. In naming a matrix, consider the rows first before the columns. For example, a matrix with three rows and four columns with be called a 3 by 4 matrix and not a 4 by 3 matrix. In the case of this question, there is an equal number of rows and columns, so even if you counted the columns first, it wouldn't be noticed. Nevertheless, always count the rows first.

Having arranged the figures in a 3 by 3 matrix,

The full data on Cable A appears on the first row. The full data on Cable B appears on the second row. The full data on Cable C appears on the third row.

The full data on Black wires appears on the first column. The full data on White wires appears on the second column. The full data on Red wires appears on the third column.

So the answer is \left[\begin{array}{ccc}3&3&2\\1&2&1\\2&1&2\end{array}\right]

Kudos!
