let r be a relation defined on set s where s is the set of all people in usa, and x r y means that x and y can communicate using the same spoken language. the relation r on s is reflexive.
Answers
Based on the information illustrated,
the relation r on s is reflexive. Therefore, it's true.
How to explain the information?If every component of a set X is related to one another, then a relation R over that set is said to be reflexive.
If (a, a) R for all A, that is, if every element of A is R-related to itself, or if aRa for every a A, then R is set to be reflexive.
In the example question, S is the set of all Park students, and R is a relation over S.
When a relationship is described as xRy, it signifies that x and y have the same biological mother.
This relation is obviously a reflexive relation. xRx means x and x has the same biological mother. In this case, the relation satisfies the requirement for all aR (a,a) R.
Therefore, it's true.

Answers
The required percentage of US states having their names starting with W is 8 %. This is gained by using the concept of percentage.
What do you mean by percentage?
The percentage is usually denoted by the symbol '%'. It is defined as the quantity or ratio which is being expressed in a fraction of 100, where 100 is the denominator.
Calculation of the percentage of US states having their names starting with W
Given:
Total states in US = 50
US states that start with the letter W = 4
Fraction in favour of the names of states starting with the letter W is given by = 4 / 50
Therefore the percentage of US states having their names starting with the letter W is equal to the fraction in favour * 100 %
= 4 / 50 * 100 %
= 4 * 2 %
= 8 %
Hence, the percentage of US states having their first letter as W is 8 %.

The difference of 3 times a number and 12 is -24.
Write and solve an equation to find the number.
Answers
The equation formed for the expression "The difference of 3 times a number and 12 is -24", is 3x - 12 = - 24, which gives the number, x = -4.
In the question, we are asked to write and solve an equation to find the number, given that the difference between 3 times the number and 12 is -24.
We assume the number to be x.
The sentence given to us is the difference between 3 times the number and 12.
Three times the number is 3x.
The difference between 3 times the number and 12 can be shown as 3x - 12.
We are given that the difference between 3 times the number and 12 is -24.
This can be shown as 3x - 12 = - 24.
This is the required equation.
To solve this, we do the following steps:
3x - 12 = -24.
Adding 12 to both sides, we get:
3x - 12 + 12 = - 24 + 12,
or, 3x = -12.
Now, we divide both sides by 3, to get:
3x/3 = -12/3,
or, x = -4.
Thus, the equation formed for the expression "The difference of 3 times a number and 12 is -24", is 3x - 12 = - 24, which gives the number, x = -4.

Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For the first translation, the orientation remains the same, just the positions changes, hence it is translated 9 units to the right and 2 units down.
For the second translation, the rule applied to each vertex was:
(x,y) -> (x,-y).
Hence it was reflected across the x-axis.
