Answers
Answer:
there is no -1 it must be one so it is now 3/4 x 4/3=12/2=1
Step-by-step explanation:
Andrew did not do that,
So, (-3/4) / (4/3) becomes (-3/4) x (3/4)
The answer is -9/16.

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.

What is the graph of y = 3jx|?
Ο Α.

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

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

Josh plans to spend at most $45 on a gift for his mother, including the $15 he plans to spend on flowers. Which inequality represents x, the range of amounts that Josh can spend on the gift?
Answers
Answer:
x ≤ $30
Step-by-step explanation:
Including the $15 for flowers, there is a budget of $45. Josh cannot spend more than $30 on a gift.
x can be less than or equal to $30
The inequality for the $x of gift x≤ 30.
What is inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age?
Olivia's age is unknown to you since the word "equals" is missing. However, because you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12.
Given:
Total amount spend on gift = $45
price of flower= $15
So, the amount of gift only is
=45- 15
=$30
Thus, Josh can only spend $30 for the gift not more than that.
Hence, the inequality for the $x of gift
x≤ 30

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

amount of change C you receive from a $50 bill?
Answers
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

[tex]\frac{3}{5}[/tex] ↔ sinC
[tex]\frac{16}{15}[/tex] ↔ cosC × tanD
[tex]\frac{4}{5}[/tex] ↔ sinD
Step-by-step explanation:
In the given triangle CBD
∵ ∠B is a right angle
∴ CD is the hypotenuse
→ We can use the trigonometry ratios
∵ sinC = opposite side of ∠C ÷ hypotenuse
∴ sinC = [tex]\frac{BD}{DC}[/tex]
∵ BD = 3 and CD = 5
∴ sinC = [tex]\frac{3}{5}[/tex]
∵ cosC = adjacent side of ∠C ÷ hypotenuse
∴ cosC = [tex]\frac{BC}{DC}[/tex]
∵ BC = 4 and CD = 5
∴ cosC = [tex]\frac{4}{5}[/tex]
∵ tanC = opposite side of ∠C ÷ adjacent side of ∠C
∴ tanC = [tex]\frac{BD}{BC}[/tex]
∵ BD = 3 and BC = 4
∴ tanC = [tex]\frac{3}{4}[/tex]
∵ sinD = opposite side of ∠D ÷ hypotenuse
∴ sinD = [tex]\frac{BC}{DC}[/tex]
∵ BC = 4 and CD = 5
∴ sinD = [tex]\frac{4}{5}[/tex]
∵ cosD = adjacent side of ∠D ÷ hypotenuse
∴ cosD = [tex]\frac{BD}{DC}[/tex]
∵ BD = 3 and CD = 5
∴ cosD = [tex]\frac{3}{5}[/tex]
∵ tanD = opposite side of ∠D ÷ adjacent side of ∠D
∴ tanD = [tex]\frac{BC}{BD}[/tex]
∵ BD = 3 and BC = 4
∴ tanD = [tex]\frac{4}{3}[/tex]
Let us find the answer to each tile
→ sinD = [tex]\frac{4}{5}[/tex] ⇒ 4th answer
→ sinC = [tex]\frac{3}{5}[/tex] ⇒ 2nd answer

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.
