After a person gets a 2% raise in salary, the new salary is $11874. What was the original salary?
Answer:
Original salary was $11641.17Step-by-step explanation:
Let the initial salary be x.
Set equation and solve for x:
x + 2% of x = 11874x + x*2/100 = 11874x + 0.02x = 118741.02x = 11874x = 11874/1.02x = 11641.17 (rounded to the nearest cent)
Answer:
The original salary is $11641.18.
Step-by-step explanation:
The equation will be,
→ x + (x × 2)/100 = 11874
Now the original salary will be,
→ x + (x × 2)/100 = 11874
→ x + 0.02x = 11874
→ 1.02x = 11874
→ x = 11874/1.02
→ x = 11641.1764706
→ [ x = 11641.18 ]
Hence, original salary is $11641.18.
Draw AABC with vertices at A(1,6), B(1, 1) and C(5, 1). In this triangle, AB²+ BC² = AC².
Next, use the GeoGebra tools to draw ADEF such that AB = DE, m/E = 90°, and
EF = BC.
Paste a picture of your drawing in the answer box.
The picture of the triangle ΔDEF is attached below.
A triangle can be defined as a basic polygon which has 3 sides.
The sum of all the interior angles of a triangle is given by 180°.The area of any triangle is calculated by [tex]\frac{1}{2}[/tex] × base × height.In a right-angled triangle the side opposite the largest angle which is 90° is called the hypotenuse.Pythagoras' theorem states that the sum of the squares of the legs of aright-angles triangle is equal to the square of the hypotenuse of the triangle.In the given ΔABC we see that AC is the hypotenuse and the two sides AB and AC are the legs of the triangle.
m∠B=90°
The ΔDEF is drawn such that m∠E=90° and AB=DE and EF=BC .
Therefore we can say that the two triangles are congruent by SAS axiom of congruency.

If x varies directly as y and when x = 5, y = 20. Find the relationship between x and y.
the relationship between x and y when x varies directly is 4 x = y.
We know that when x varies directly with y, then:
x = k y
Now, we have x = 5 and y = 20
Substituting the values in the expression, we get that:
5 = 20 k
k = 5 / 20
k = 1 / 4
So, we get the relation as:
x = 1 / 4 y
4 x = y
Therefore, the relationship between x and y when x varies directly is 4 x = y.

Write a function g whose graph represents the indicated transformation of the graph of f.
f(x) = 3x ; translation 5 units up
the translated function is g(x) =
Answer:
g(x) = 3x +5
Step-by-step explanation:
You want the function that results from translating f(x) = 3x upward by 5 units.
TranslationThe y-coordinate of a point tells how far above the x-axis it is. Adding 5 to the y-coordinate will move that point 5 units farther above the x-axis, which is to say 5 units upward.
The y-coordinate of a point on a graph is the value of the function of the x-coordinate of that point. That is, each point is (x, f(x)). If we want to translate that point 5 units upward, we add 5 to the function value:
(x, f(x) +5) . . . . . graph translated 5 units up
Using the given definition of f(x), this becomes ...
(x, 3x +5)
The translated function is defined as g(x), so we have ...
(x, g(x)) = (x, 3x +5)
or ...
g(x) = 3x +5
7. An aircraft flies 400 km from a point O on a bearing of 025°
and then 700 km on a bearing of 080° to arrive at B.
a) How far north of O is B?
b) How far east of O is B?
Answer:
484 km north858 km eastStep-by-step explanation:
You want the distances north and east of the origin that a plane ends up after flying 400 km at a bearing of 25°, then 700 km at 80°.
Coordinate transformationFor some distance r and bearing angle θ, the (north, east) coordinates will be ...
(north, east) = (r·cos(θ), r·sin(θ))
ApplicationFor the trip at hand, the final coordinates of the plane are ...
a)Distance north = (400 km)cos(25°) +(700 km)cos(80°)
= 362.52 km +121.55 km = 484.07 km
B is about 484 km north of O.
b)Distance east = (400 km)sin(25°) +(700 km)sin(80°)
= 169.05 km +689.37 km = 858.41 km
B is about 858 km east of O.

what is the perimeter of a regular, triangular yield sign with aside length of 15 in
45 inches s the perimeter of a regular, triangular yield sign with aside length of 15 in
What is perimeter?The perimeter of a shape is the sum of the lengths of all its edges. For example, a triangle has three edges, so its perimeter is equal to the sum of those three lengths.
The perimeter of a square can be easily calculated if one side and all other sides are given as being the same length; for example, a square with sides measuring 5 inches long has a perimeter of 20 inches because 5 x 4 = 20. By multiplying the sum of the length and width by two, one can determine a rectangle's perimeter.
We will use the simple perimeter formula as yield sign is equilateral triangle

The fraction 24/56 can be simplified to 3/7, and we can't keep simplifying this.
How to simplify the given fraction?Here we want to simplify the fraction 24/56. To do so, we need to find the greatest common factor between 24 and 56, to find that, we need to write both of these numbers as a product of their prime factors.
We will get:
24 = 2*2*2*3
56 = 2*2*2*7
We can identify the greatest common factor between parenthesis:
24 = (2*2*2)*3
56 = (2*2*2)*7
So the greatest common factor is 2*2*2 = 8, then we can divide both numerator and denominator by 8, we will get:
24/8 = 3
56/8 = 7

if angle 2=6x+8 and angle 4=4x+11 what is the value of angle 2?
Answer:
17
Step-by-step explanation:
Angle 2 and angle 4 are alternate exterior angles so they congruent angles which means they have same angle measurement.
To find the measure of angle 2 we first need to find the value of x.
And to do that we can write the following equation based on the information we have in hand:
6x + 8 = 4x + 11 transfer like terms to the same side of the equation
6x - 4x = 11 - 8 add/subtract like terms
2x = 3 divide both sides by 2
x = 1.5 now to find the measure of angle 2 replace x with 1.5

What is the slope of a line that passes through the ordered pairs (0,1) and (3,5)?
The slope of a line that passes through the ordered pairs (0,1) and (3,5) would be m = 4/3.
What is the slope of a line which passes through points ( p,q) and (x,y)?Slope tells how vertical a line is.
The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
WE have been given line that passes through the ordered pairs (0,1) and (3,5).
Slope = m
Therefore,
[tex]m = \dfrac{y-q}{x-p}\\\\m = \dfrac{5 -1}{3-0}\\\\m = \dfrac{4}{3}[/tex]

mayas penny bank is 1/2 full. after she adds 120 pennies,it is 2/3 full. How,many pennis can mayas bank hold?
Answer:
720
Step-by-step explanation:
We are looking for the difference between 2/3 and 1/2, which we know to be 120. To subtract fractions of different denominators, we need to find the common denominator (this can be found by finding the LCM of both denominators)
120 = 2/3 - 1/2 = 4/6 - 3/6
1/6 = 120
We can multiply 120 by 6 to find the value of the full bank.
1/1 = 720

The coordinates of the vertices E (-8,9), F(-4,9), G(-4,2), and D(2,-8) when rotated 90° counterclockwise around the origin of the new coordinates will be E'( - 9, - 8 ), F'( - 9, - 4 ), G'( - 2, - 4 ), and D'( 8, 2 ).
A point A( x, y ) becomes A' when a point is rotated 90 degrees counterclockwise about the origin ( - y, x ). To put it another way, flip x and y, and make y negative.

A theater charges $8 for main-floor seats and $4 for balcony seats. If all seats are sold, the ticket income is $5200. At one show, 25% of the main-floor seats and 50% of the balcony seats were
income was $1800 How many seats are on the main floor and how many are in the balcony?
By solving a system of equations we can see that there are 400 main-floor seats and 500 balcony seats.
How many seats are on the main floor and how many are in the balcony?Let's define the two variables:
x = number of seats on the main-floor.y = number of balcony seats.We know that if all the seats are sold, then the total income is $5,200, we can write the equation:
x*$8 + y*$4 = $5,200
And if 25% of the main-floor and 50% of the balcony seats are sold, then we get an income of $1800, then we can write:
0.25*x*$8 + 0.5*y*$4 = $1,800
x*$2 + y*$2 = $1,800
So we have a system of equations:
x*$8 + y*$4 = $5,200
x*$2 + y*$2 = $1,800
If we subtract twice the second equation for the first one we get:
(x*$8 + y*$4) - (x*$2 + y*$2) = $5,200 - 2*$1,800
x*$4 = $1,600
x = $1,600/$4 = 400
So there are 400 seats on the main-floor.
Using the first equation we can find:
x*$8 + y*$4 = $5,200
400*$8 + y*$4 = $5,200
$3,200 + y*$4 = $5,200
y*$4 = $5,200 - $3,200 = $2,000
y = $2,000/$4 = 500
So there are 500 balcony seats.

A parallelogram's opposite or facing sides are of equal length, and its opposite angles are of equal measure. The congruence of opposite sides and angles is a direct result of the Euclidean parallel postulate, and neither condition can be proven without resorting to the Euclidean parallel postulate or one of its equivalent formulations.The net is made up of six parallelograms, each representing one of the box's faces.
Four rectangular faces with dimensions of 6 ft × 4 ftThe other two faces are square in shape, with side lengths of 4 feet.The area represented by the net can be used to estimate how much cardboard Jayden will need to make the box.
