El señor Antonio Rodríguez compro en efectivo una televisión de plasma de $138,860.00. Le otorgan un descuento de la 20% ¿Cuanto pago por la televisión?
Answer:
$111,088
Step-by-step explanation:
Paso 1
Encuentra el descuento
Costo de la televisión de plasma = $ 138,860.00
Porcentaje de descuento = 20%
Descuento = 20% × $ 138,860
Descuento = $ 27,772
Paso 2
¿Cuánto pago por la televisión?
Esto se calcula como:
$ 138,860 - $ 27,772
= $ 111,088
Por lo tanto, la cantidad que paga por la televisión es de $ 111,088
Solve the following equation:

Will mark as brainliest.
Given:
The equation is
[tex]\dfrac{5}{6}h+\dfrac{6}{7}h-\dfrac{9}{14}h=4[/tex]
To find:
The solution of the given equation.
Solution:
We have,
[tex]\dfrac{5}{6}h+\dfrac{6}{7}h-\dfrac{9}{14}h=4[/tex]
It can be written as
[tex]\left(\dfrac{5}{6}+\dfrac{6}{7}-\dfrac{9}{14}\right)h=4[/tex]
[tex]\left(\dfrac{35+36-27}{42}\right)h=4[/tex]
[tex]\left(\dfrac{44}{42}\right)h=4[/tex]
[tex]\dfrac{22}{21}h=4[/tex]
Multiply both sides by 21.
[tex]22h=84[/tex]
Divide both sides by 22.
[tex]h=\dfrac{84}{22}[/tex]
[tex]h=\dfrac{42}{11}[/tex]
Therefore, the solution of the given equation is [tex]h=\dfrac{42}{11}[/tex].

Answer:
The scale factor is 1 to 3
Step-by-step explanation:
Here, we want to get the scale factor
we can use the coordinates of the vertices of the small image and the vertices of the large image to get this
We have;
(2,5) going on to give (6,15)
As we can see, the vertices of the small shape are multiplied by 3 to give that of the big shape
So also we can see for the other vertices
This means that the scales factor is 1 to 3

Find the values of x and y.
Answer:
x=30° y=5
Step-by-step explanation:
All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.
so
8y=40
y=40/8
y=5
Since it's an equilateral triangle. All angles are equal And each angle has dimensions
=180°/3=60°
The angle of the straight line = 180°
so The obtuse angle of the lower isosceles triangle is 180°-60°=120°
The angles at the base of the isosceles triangle are equal
so 2x° = 180°-120°
2x°=60°
x°=60°/2
x°=30°

Answer:
Evaluating the piecewise function when X =3, we get f(3) = 7
Step-by-step explanation:
Given the following piecewise function
f(x)= { 2x+1; where x > 0
-3 when x ≤ 0
Evaluate the function when X = 3
We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0
We can't use -3, because x ≤ 0, and 3 is not less than 0.
Now, evaluating the function:
[tex]f(x)=2x+1\\Put\:x=3\\f(3)=2(3)+1\\f(3)=6+1\\f(3)=7[/tex]
So, Evaluating the piecewise function when X =3, we get f(3) = 7

What is the slope of the line x = 4?
Answer:
its undefined
Step-by-step explanation:
Select the correct answer.
The slope of the function on the left is multiplied by p, and is added to the yIntercept to arrive at the function on the right. Which of the
following are the values for p and q?
A. p = -2 and q = -2
В. p=-2 and q = -4
C. P = 2 and q = -3
D. P = -2 and q = -3
Answer:
p = -2
q = -3
Step-by-step explanation:
Let us get the equation of the two graphs
General equation form is;
y = mx + b
m is slope and b is the y-intercept
For the first one;
y intercept is 1
So the equation is;
y = mx + 1
The x-intercept is -2
the value of y at the x-intercept is 0
0 = -2m + 1
1 = 2m
m = 1/2
so;
1/2 * p
p/2
q added to y-intercept;
q + 1
Let us get the equation of the second plot
y-intercept is -2
Equation is;
y = mx - 2
We can get slope using x-intercept
x-intercept is -2
0 = -2m - 2
2m = -2
m = -1
So;
p/2 = -1
p = 2 * -1 = -2
For the value of q;
q + 1 = -2
q = -2-1 = -3

The sum of two complimentary angles is 90. . For one pair of complimentary angles, the measure of the first angle is 15 less than twice the measure of the second angle.
Answer:
[tex]x=55 \textdegree[/tex]
[tex]y=35 \textdegree[/tex]
Step-by-step explanation:
From the question we are told that
Sum of two angle =90
First angle is 15 less than twice the measure of the second angle.
Generally interpreting mathematically we have
Let x be the first angle and second angle y
[tex]x=2y-15[/tex]
Therefore
[tex]2y-15 +y=90[/tex]
[tex]3y=105[/tex]
[tex]y=\frac{105}{3}[/tex]
[tex]y=35 \textdegree[/tex]
Therefore
[tex]x+35=90[/tex]
[tex]x=90-35[/tex]
[tex]x=55\textdegree[/tex]
Abakery can make 100 pies in 2 hours.
How many hours will it take, if they
need to do 350 pies?
Answer:
7 hours
Step-by-step explanation:
The bakery could bake 100/2 = 50 pies per hour.
To make 350 pies, the bakery requires 350/50 = 7 hours.
The answer is therefore 7 hours.
A taxi driver records the time required to complete various and the distance for each trip. The best-given fit line by the equation y=0.467x + 0.417, where y represents the distance miles, and x represents the time for the trip in minutes. Estimate the distance for a trip that takes 20 minutes, show your reasoning
Using the line of best fit, it is found that the estimated distance for a trip that takes 20 minutes is of 9.757 miles.
What does the line of best fit gives?It gives the estimated distance in miles of a trip that takes x minutes, according to the following function?
y = 0.467x + 0.417.
In this problem, the trip took x = 20 minutes, hence the distance is given by:
y = 0.467 x 20 + 0.417 = 9.757 miles.
