A lot depends upon your interpretation of "opposite."  Do you mean "reciprocal?"

If you give the number a, the reciprocal would be 1/a.  Is that what you mean?

Or do you mean "the number with opposite sign?"  If you give the number b, "the number with opposite sign" would be -b.

Consider both cases.  Choose a rational number (such as 7/8).  Find the reciprocal of this number.  Find the number with opposite sign of this number.

"Nya plans these steps before coding in a program.
Scrat [10]

The program would display "n = 3" as output based on Nya's steps.

<h3>What is a pseudocode?</h3>

A pseudocode simply refers to a description of the steps contained in an algorithm, especially through the use of a plain (natural) language.

<u>Note:</u> π is equal to 3.14.

Since Nya assigns π, which isn't an integer, the program would determine the integer (n) as follows:

x - 1 < n < x

π - 1 < n < π

Substituting the parameter (3.14) into the formula, we have;

3.14 - 1 < n < 3.14

2.14 < n < 3.14

n = 3.

You walk around a circle which has a diameter of 9 m, how far have you walked?
Snezhnost [94]

Answer:

C =28.26m

Step-by-step explanation:

We are walking around a circle, which means we are finding the perimeter.  The perimeter of a circle is called the circumference.

We find the circumference by

C = pi *d  where d is the diameter

C = 3.14 * 9

C =28.26m

You need to put your reindeer, Lancer, Prancer, Gloopin, and Bloopin, in a single-file line to pull your sleigh. However, Prance
marysya [2.9K]

Answer:

P43=4!(4–3)!=241=24

Step-by-step explanation:

There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.

This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:

P43=4!(4–3)!=241=24
