after a 30% reduction, you purchase a dictionary for $30.80 what was the dictionary price before the reduction

Answers

Answer 1

Answer:

Well the original price would be $44

Step-by-step explanation:

So make an equation

Lets make X stand for the price before the deduction

so x-x(0.3)=30.80

Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change

Now just solve the equation

You’ll get 44.

En una panadería se elaboraron 140 panes diarios, el 25% son conchas, 10% cortadillos, 40% donas y 25% bolillos. Cada pieza de pan tiene un costo de $8 pesos. ¿Cuanta ganancia se obtuvo en la venta de donas?, ¿Y cuanta ganancia se obtuvo en la venta de bolillos ?

Answers

Answer:

Se obtuvo $ 448 de ganancia por la venta de donas.

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Step-by-step explanation:

1) ¿Cuanta ganancia se obtuvo en la venta de donas?

La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:

[tex]C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)[/tex]

[tex]C = 448\,USD[/tex]

Se obtuvo $ 448 de ganancia por la venta de donas.

2) ¿Cuanta ganancia se obtuvo en la venta de bolillos?

La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:

[tex]C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)[/tex]

[tex]C = 280\,USD[/tex]

Se obtuvo $ 280 de ganancia por la venta de bolillos.

In this exercise we have to use the knowledge of finance to calculate the profit.

1) $ 448 profit was made from donut sales.

2) A profit of $ 280 was obtained from the sale of cupcake.

1)The profit is the product of the percentage produced of donuts, expressed as a ratio, the unit price of the donut and the total produced of breads. That is to say:

[tex]C= (\frac{40}{100} )*(140)*(8)= 448 USD[/tex]

$ 448 profit was made from donut sales.

2) The profit is the product of the percentage of cupcake produced, expressed as a ratio, the unit price of the cupcake and the total amount of bread produced. That is to say:

[tex]C= (\frac{25}{100}) *(140)*(8)= 280 USD[/tex]

A profit of $ 280 was obtained from the sale of cupcake.

In 2007, the population of Ecuador was estimated at
13.8 million, with an annual growth rate of 1.6%. If this
rate continues, estimate when the population will reach
15 million.

Answers

Answer:

In 2012 , the population will be 15 million

Step-by-step explanation:

We start by setting up an exponential equation that defines the increase

P(t) = I(1 + r)^t

P(t) represents the present population = 15 million

I is the population in 2007 which is 13.8 million

r is 1.6% = 0.016

t is what we want to calculate

15 million = 13.8 million (1 + 0.016)^t

15/13.8 = (1.016)^t

1.09 = (1.016)^t

ln 1.09 = t ln 1.016

t = ln 1.09/ln 1.016

t = 5.429 which is approximately 5

So in 2007 + 5 = 2012, the population will be 15 million

10 points! Daryl has a scholarship that pays 80% of his tuition for all four years he attends college. What is the total value of the scholarship if the tuition is $13,500 per year?

Answers

Answer:

The value of the scholarship is $10800

Step-by-step explanation:

Step one:

Daryl has a scholarship that pays 80% of his tuition per year

the total value of the scholarship if the tuition is $13,500 per year

Step two:

let us solve for the value of 80% of the tuition which is $13,500 per year.

this is calculated as

=80/100*13,500

=0.8*13,500

=10,800

You buy x pounds of cherries for $2.99/b. What is a function rule for the
amount of change C you receive from a $50 bill?

Answers

If your choices are

A. C = 2.99x - 50
B. C = 50 - 2.99x
C. C = 50x - 2.99
D. C = 2.99 - 50x

2.99x

That’s the money you owe for the cherries. That eliminates choices C and D.

50 - 2.99x

When x is zero you should get 50 dollars back, so that eliminates A. You get 50 dollars back minus the money that you owe for the cherries, so that's choice B.

B. C = 50 - 2.99x

SAS Similarity Theorem C. SSS Similarity Theorem D. Any of the above could be used to show that the triangles are similar.

Answers

Answer:

1) Please find attached the given plot and sketch of the points created with Microsoft Word

2) The correct option is;

A. AA Similarity Postulate

Step-by-step explanation:

1) Please find attached the given plot and sketch of the points created with Microsoft Word

2) The given parameters are;

The coordinates of the points are A(0, 0), B(1, 0), C(1, 2), D(2, 0) and E(2, 4)

Therefore, we have;

The length of segment AB = 1

The length of segment BC = 2

The length of segment AD = 2

The length of segment DE = 4

Therefore, we have;

∠ABC = ∠ADE = 90°

∠BAC = = artctan(2/1) = ∠DAE = artctan(4/2) = 63.435°

Therefore, ΔABC and ΔADE are similar by AA Similarity Postulate

Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan rides at a constant speed of 8 miles per hour, and Nathan rides a constant speed of 10 miles per hour. How long does it take until Reagan and Nathan meet?

Answers

Answer:

They meet in 2.22 hours.

Step-by-step explanation:

We can find the time at which Reagan and Nathan meet by equaling the time as follows:

[tex] v_{R} = \frac{x_{R}}{t} [/tex]  

[tex] x_{R} = v_{R}t [/tex]    (1)      

[tex] v_{N} = \frac{x_{N}}{t} [/tex]  

[tex] x_{N} = v_{N}t [/tex]   (2)

Where R is for Reagan and N for Nathan.

Knowing that:

[tex] x_{R} + x_{N} = 40 mi [/tex]

By adding equations (1) and (2) we have:

[tex] x_{R} + x_{N} = v_{R}t + v_{N}t [/tex]

[tex] t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h [/tex]

Therefore, they meet in 2.22 hours.        

I hope it helps you!

Which is the graph of the linear inequality x – 2y > –6?

Answers

Answer:

uhhh d????

Step-by-step explanation:

Graph D represents the  linear inequality x – 2y > –6.

The given inequality is x – 2y > –6.

We rearrange the inequality as y < (1/2)x + 3

Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).

To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).

The slope of the graph is 1/2.

However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.

Hence, graph D represents the  linear inequality x – 2y > –6.

What is a circle?

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

If the two chords of the circle intersect at a point, then the product of the segments of the chord will be equal.

We know that the product of (x - 5) & (x - 8) and (x - 5) & (x) will be equal. Then we have

(x - 5) · (x - 8) = (x - 11) · x

Simplify the equation, then the value of the  variable x will be

(x - 5) · (x - 8) = (x - 11) · x

x² - 13x + 40 = x² - 11x

2x = 40

x = 20

Thus, the value of the variable x is 20.

Then the correct option is A.

Answers

Note: Your question sounds a little unclear and incomplete. I assume you want to get the idea about the graph of 3|x|. My answer may still clear your concept about the graphs.

Answer:

The graph of y=3|x| is attached below.

Step-by-step explanation:

Given the function

[tex]y=3\left|x\right|[/tex]

Determining the domain:

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

The function has no undefined points nor domain constraints. Therefore, the domain is:

[tex]-\infty \:<x<\infty \:[/tex]

Determining the range:

We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

[tex]\mathrm{The\:range\:of\:an\:absolute\:function\:of\:the\:form}\:c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k[/tex]

[tex]k=0[/tex]

[tex]f\left(x\right)\ge \:0[/tex]

Thus,

[tex]\mathrm{Range\:of\:}3\left|x\right|:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]

Determining the x-intercept and y-intercept:

From the graph, it is clear that at x=0, y=0. Therefore, the y-intercept is (0, 0)From the graph, it is clear that at y=0, x=0. Therefore, the y-intercept is (0, 0)
