% raise. What was the employee's hourly pay before raise? Round your answer to the nearest cent.
The employee's pre-raise salary was $ ____
Answers
The employee's pre-raise salary was $18.75
What was the employee's hourly pay before raise?The given parameters are
New hourly pay = $20.25
Raise = 8%
The new hourly pay of the employee is calculated using
New hourly pay = Pre-raise salary * (1 + raise)
This gives
20.25 = Pre-raise salary * (1 + 8%)
Divide both sides by 1 + 8%
Pre-raise salary = 18.75
Hence, the employee's pre-raise salary was $18.75

In linear equation, the intersection at coordinate (9, 315).
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Gym one:
f(x) =80 x + 25
Gym two:
g(x) = 35x (+ 0 [since there was no joining fee])
The first month is easy.
Gym one's cost is just the joining fee plus the one month of membership fee. Or...
105 = 80(1) + 25
Gym two's cost is just that first month's membership fee. Or...
35 = 35(1) + 0
then second month
[f(x) = 185 = 80(2)+25
g(x) = 70 = 35(2)],
then a tenth month [
f(x) = 825 = 80(10) + 25;
g(x) = 350 = 35(10)]

The sum of two vectors is the ₋resultant .
Answers
Given statement 'The sum of two vectors is the resultant.' is True.
We know that in mathematics, a vector is a quantity that has both magnitude and direction but no position.
Examples : velocity, force and acceleration.
Also, the resultant vector is the vector sum of two or more vectors. We find the resultant vectors by adding two or more vectors together. Any two vectors can be added if and only if they are the same vector quantity.
For vector P = [tex]a\vec i+b\vec j[/tex] and vector Q = [tex]m\vec i+n\vec j[/tex]
The resultant vector R would be,
R = P + Q
R = [tex](a+m)\vec i+(b+n)\vec j[/tex]

Determine whether each sequence is geometric. If so, identify the common ratio and find the next two terms. 1,3,5,7, . . . .
Answers
The sequence is in an arithmetic sequence, common difference is 2, next two term is 9 and 11.
The arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
Here the sequence is 1, 3, 5, 7....
Here the sequence is in arithmetic sequence, so the common difference(d) is 3-1 = 5-3 = 2
So the common difference is 2
Now we need to find the next two terms, and for this, we have the formula to find the nth term of the sequence,
[tex]a_{n}[/tex] = a + (n-1)d
We have to find the 5th and 6th terms.
[tex]a_{5}[/tex] = 1 + 4×2
= 1 + 8
= 9
[tex]a_{6}[/tex] = 1 + 5×2
= 1 + 10

The interior angle measure of a regular polygon is given. Identify the polygon.
135
Answers
The regular polygon with an interior angle of measure 135 is an octagon.
A regular polygon is a polygon that has equal side lengths and equal interior angle measures.
Interior angle of a polygon is the angle inside it that is formed by two adjacent sides. The number of interior angles formed inside a polygon is the same as the number of its sides. Meanwhile, the sum of all the interior angles of any polygon is constant to that polygon and depends on the number of sides.
sum = 180(n - 2)
Let n = number of sides of the polygon = number of interior angles
sum = measure of interior angle x n
Using the formula,
sum = 180(n - 2)
135n = 180(n - 2)
135n = 180n - 360
180n - 135n = 360
45n = 360
n = 8
If the polygon has 8 sides and 8 interior angles, then the regular polygon is an octagon.

32(-5) + 0 + 160 = 0 is the line in the general form of the line the passing through (−5,0) with the slope 32.
What is slope?A number that describes a line's direction and steepness is known as the slope or gradient of a line in mathematics. There is no obvious reason why the letter m is used to represent slope, although it first appears in English in O'Brien (1844), who wrote the equation for a straight line as "y = mx + b," and it may also be found in Todhunter (1888), who wrote it as "y = mx + c."
Let us write the given data in slope-intercept form that is
y = m(x) + b
where m = slope of the line
b = y-intercept
So substituting the values we get
0 = 32(-5) + b
-b = -160
b = 160
so we have the slope intercept form
0 = 32(-5) + 160

An executive invest $21,000, some at 8% and the rest at 5% annual interest. if he receives an annual return of $1,470, how much is invested at each rate
Answers
Using algebraic expression and equation, an executive assistant invested $14,000 and $7,000 at the rate of 8% and 5% annual interest, respectively.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that an executive invest a total of $21,000, we can express this as:
x + y = 21,000 ⇒ x = 21,000 - y (equation 1)
where x = amount invested at 8% annual interest
y = amount invested at 5% annual interest
If the annual return is $1,470, then the sum of the product of the rate and the amount is equal to the annual return.
8%x + 5%y = $1,470
0.08x + 0.05y = 1,470 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
0.08(21,000 - y) + 0.05y = 1,470
1680 - 0.08y + 0.05y = 1470
-0.03y = -210
y = 7000
amount invested at 5% annual interest = $7000
x = 21,000 - y
x = 21,000 - 7000
x = 14,000
amount invested at 8% annual interest = $14000

Answers
Answer:
X = √2 R , where X is the length of the legs as R is the length of the radius .
Step-by-step explanation:
The opposite sides of two same angled triangle is also same . So in this case we can say two legs are in same length as their opposite angles are same (45°)
Now , suppose the given radius is R (look at the diagram) then total diameter is 2R ( DIAMETER = 2 × RADIUS )
Now , we will consider the length of the legs are X ( as the are same ).
Now, we will apply Pythagoras theorem ( The squares on the legs of a right triangle is equal to the square on the hypotenuse . )
∵ X² + X² = (2R)²
or , 2X² = 4R²
or, X² = 2R²
We will root both side
X = √2R
So , X is the length of the legs as R is the length of the radius .

According to the given question.
We have an equation 1/x + x/2 = x+ 4/2x.
Since, we have to solve th egiven equation 1/x + x/2 = x+ 4/2x, for x.
Therefore, the solution of the given equation 1/x + x/2 = x+ 4/2x for x is given by
1/x + x/2 = x+ 4/2x
⇒ 1/x - 4/2x = x - x/2
⇒ 1/x -2/x = x - x/2
⇒ (1-2)/x = (2x -x)/2
⇒ -1/x = x/2
⇒ -2 = x^2

= -2x - 9 + 3x + 7
= x - 2
-x - 11 - (-2x - 9)
= - x - 11 +2x + 9
= x - 2
So, it is Arithmetic.
Answer:
Arithmetic sequence.
Common difference = -x - 11
Step-by-step explanation:
This is an arithmetic sequence.
-3x - 7, -2x - 9, -x - 11, ...
Find the common difference.
Common difference =second term - first term.
= -2x - 9 - (-3x - 7)
= -2x - 9 + 3x +7
= -2x + 3x - 9 + 7 {Combine like terms}
= x - 2
If we add the common difference to the second term, we will get the third term.
Third term = second term + common difference
= -2x - 9 + x - 2
= -2x + x - 9 - 2
= -x - 11.
Hence this is an arithmetic sequence.

What is an inscribed square?
A square is inscribed in a circle or a polygon if its four vertices are on the circle's circumference or the polygon's sides.
Inscribed in the circle is a square that fits snugly inside a circle. The square's corners will touch but not intersect the circle's boundary, and the diagonal of the square will equal the diameter of the circle. Furthermore, as with any square's diagonal, it equals the hypotenuse of a 45°-45°-90° triangle.
Let the side of the square inscribed in a square be a units.
Hence, the required ratio is 2 : 1.
Let ABCD be a square inscribed in a circle of radius 'r'.
Now, the diameter of the circle is the diagonal of the square.
Therefore, BD = 2r.
In △BDC, using Pythagoras theorem
