a certain tv can be purchased from the manufacturer for $160. A certain online retailer gas a standard markup for 30%, and a certain superstore has a standard markup of 40%
what is the price of the tv when purchased online?

Answers

Answer 1

Answer:

208

Step-by-step explanation:

basically you can plug this into a calculator, just by pressing 160 + 30(then the percent sign), followed by the equal sign. or you can do it on paper by dividing 160 by 100, which gives you 1.6. then you multiply that by 30, with leaves you with 48. and because 48 is 30% of 160, you do 48 + 160 equals 208.

PICTIURE:https://homework.russianschool.com/resource?key=00j42

Answers

Answer:

[tex]CD=3\sqrt{3}\ cm,\\ \\A_{ABC}=18\sqrt{3}\ cm^2[/tex]

Step-by-step explanation:

Triangle ABC is right triangle. Since  m∠ACB = 90°  and m∠ACD = 60°, you get m∠BCD = 90°-60°=30°.

Triangle BCD is rigth triangle, then the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,

[tex]BD=\dfrac{1}{2}BC=\dfrac{1}{2}\cdot 6=6\ cm.[/tex]

By the Pythagorean theorem,

[tex]CD^2=BC^2-BD^2=6^2-3^2=36-9=27,\\ \\CD=3\sqrt{3}\ cm.[/tex]

Then

[tex]CD^2=AD\cdot BD,\\ \\27=3\cdot AD,\\ \\AD=9\cm.[/tex]

Hypotenuse AB of the triangle ABC is equal to

[tex]AB=AD+BD=9+3=12\ cm.[/tex]

The area of the triangle ABC is

[tex]A_{ABC}=\dfrac{1}{2}\cdot AB\cdot CD=\dfrac{1}{2}\cdot 12\cdot 3\sqrt{3}=18\sqrt{3}\ cm^2.[/tex]

CD is √3 cm, and the area of right-angled triangle ABC, with ∠ACB = 90° and ∠ACD = 60°, is 9 cm², obtained by applying the Pythagorean Theorem and area formula.

The given triangle is right-angled at C (as per the given condition m∠ACB = 90°), and ∠ACD is 60°.

Thus, we know that ΔACD is a 30-60-90 triangle because the remaining angle of the triangle (∠ADC) would have to be 30° (since all angles in any triangle sum up to 180°).

In a 30-60-90 triangle, the ratio of the sides opposite to these angles respectively is 1 : √3 : 2. This tells us AC is 2 times the length of CD and AC is √3 times the length of AD.

We don't have the lengths of AC, AD, or CD yet, but we can solve for CD using the Pythagorean Theorem in triangle ABC. Since it's a right triangle, the square of the hypotenuse (AC in our case) is equal to the sum of the squares of the other two sides. We can express this as:

AC² = BC² - CD²

Substituting AC = 2CD into this equation, we get:

(2CD)² = 6² - CD²

Solving this equation yields CD = BC / (2 √3) = 6 / (2 √3) = √3 cm

So the length of CD is √3 cm.

Now let's find the area of triangle ΔABC. The area is typically given by the formula 0.5 * base * height.

In this case, BC is the base of triangle ABC, and CD is the height due to its perpendicular nature to side AB by the given condition (CD ⊥ AB). So, the calculation would go as follows:

Area = 0.5 * BC * CD = 0.5 * 6 cm * √3 cm = 3 √3 cm².

But by rationalizing the denominator, which is a common practice especially when having square roots in the denominator, we get Area = 3√3 * √3 * √3 cm² = 3 * 3 cm² = 9 cm².

Therefore, CD = √3 cm and the area of ΔABC is 9 cm².

Which equation correctly shows the multiplication of the means and extremes in the proportion 13⁄78 = 9⁄54?

A. 13 ⋅ 9 = 78 ⋅ 54
B. 78 ⋅ 13 = 54 ⋅ 9
C. 13 ⋅ 54 = 78 ⋅ 9
D. 13 ⋅ 9 = 78 ⋅ 13

Answers

13 • 54= 78•9 is the correct answer.
When we cross multiply for proportions we put the sets of numbers in “fraction” form across from one another, then we multiply the top number from the first set by the bottom number of the second set. And the same thing for the top number of the second set and the bottom number of the first set.

The correct equation for the multiplication of means and extremes in the proportion 13/78 = 9/54 is C, which states 13 * 54 equals 78 * 9.

The equation that correctly shows the multiplication of the means and extremes in the proportion 13/78 = 9/54 is option C. This can be demonstrated by cross-multiplying the terms of the two ratios, where the product of the means (the two middle terms) is equal to the product of the extremes (the two outer terms). Therefore, the correct equation is 13 * 54 = 78 * 9.

To check, we can multiply the numbers:

13 * 54 = 70278 * 9 = 702

Both products are equal, confirming that option C is the correct answer.

Write the values of y, for which the equation has sense.

Answer: y = 3


Step-by-step explanation:

The objective is to get 0 on the left side to equal the 0 on the right side. I'd like to do this by making the sum of x^2 and y^2 equal to 10. If (x^2+y^2) = 10, the -10 on the left side will cancel it out to equal 0.

1^2 = 1

3^3 = 9

1 + 9 = 10

Therefore, x is 1 and y is 3.

x^2 + y^2 - 10 = 0

1^2 + 3^2 - 10 - 0

Is molded after this equation:

[tex]Population_{final}=Population_{initial}(1+r)^t[/tex]

Where 1 represents 100%, r is the rate in decimals and t is time.

So this means that the initial population is 16.8 thousand or in other words 16,800 people.  The rate is 1-r, so the rate that the population is decreasing is 0.06 i.e. 6% (because 1-0.06=0.94).

Find the range of the function.

ƒ(x) = 3x2 − 8

Answers

It's a quadratic function.

[tex]f(x)=ax^2+bx+c[/tex]

----------------------------------

[tex]f(x)=3x^2-8[/tex]

a = 3, b = 0, c = -8

a = 3 > 0, therefore the parabola open up.

The range of this function is [k, ∞).

k - second coordinate of the vertex (h, k)

[tex]h=\dfrac{-b}{2a},\ k=f(h)[/tex]

Substitute:

[tex]h=\dfrac{-0}{2(3)}=0\\\\k=f(0)=3(0^2)-8=0-8=-8[/tex]

Answer: The range is [tex][8,\ \infty)[/tex]

Final answer:

To find the range of the function ƒ(x) = 3x^2 - 8, we need to determine the set of all possible output values. The range of the function is all real numbers greater than or equal to the y-coordinate of the vertex, which is -8. Therefore, the range of the function ƒ(x) = 3x^2 - 8 is y ≤ -8.

Explanation:

To find the range of the function ƒ(x) = 3x2 − 8, we need to determine the set of all possible output values. Since the function is a quadratic function, its graph is a parabola. The range can be found by considering the vertex of the parabola and the direction it opens.

The vertex of the parabola is given by the formula x = -b/(2a), where a and b are the coefficients of the quadratic function. In this case, a = 3 and b = 0. So, the x-coordinate of the vertex is x = -0/(2*3) = 0.

Since the parabola opens upward (the coefficient of x2 is positive), the vertex represents the minimum value of the function. Therefore, the range of the function is all real numbers greater than or equal to the y-coordinate of the vertex. Plugging the x-coordinate (0) into the function gives us ƒ(0) = 3*(0)2 − 8 = -8. So, the range of the function ƒ(x) = 3x2 − 8 is y ≤ -8.

The rule for the number of fish in a home aquarium is 1 gallon of water for each inch of fish length. Marta's aquarium holds 33 gallons of water and Hank's aquarium hold 45 gallons of water. The aquarium holds two types of fish, fish A and fish B. If Marta bought 3 of fish A and 2 of fish B, and Hank bought 3 of fish A and 4 of fish B, how long is fish A and how long is fish B?

Answers

Answer:A: 7 inchesB: 6 inchesStep-by-step explanation:

We can let the variables A and B stand for the length in inches of fish A and fish B, respectively.

If we assume each person bought fish having a total length of 1 inch per gallon of aquarium, then we can write equations ...

... 3A +2B = 33 . . . . . total length of Marta's fish

... 3A +4B = 45 . . . . . total length of Hank's fish

Subtracting the first equation from the second, we get ...

... 2B = 12

... B = 6 . . . . . divide by 2

Using this value in the first equation, we have ...

... 3A + 2·6 = 33

... 3A = 21 . . . . . . . . subtract 12

... A = 7 . . . . . . . . . . divide by 3

Fish A is 7 inches long; fish B is 6 inches long.

Final answer:

To determine the lengths of fish A and fish B, two simultaneous equations were formed using the information provided. Solving these equations resulted in finding that fish A is 7 inches long and fish B is 6 inches long.

Explanation:

The problem revolves around figuring out the length of fish A and fish B given the rule that each inch of fish requires 1 gallon of water.

Marta's aquarium holds 33 gallons and she bought 3 of fish A and 2 of fish B. Hank's aquarium holds 45 gallons and he bought 3 of fish A and 4 of fish B. Let's denote the length of fish A as 'a' inches and fish B as 'b' inches.

Marta's equation: 3a + 2b = 33 (1)

Hank's equation: 3a + 4b = 45 (2)

To find the length of fish A and B, we solve these simultaneous equations:

Multiply equation (1) by 2: 6a + 4b = 66Subtract equation (2) from this new equation:
6a + 4b - (3a + 4b) = 66 - 45
3a = 21
a = 7 inchesNow plug the value of 'a' into equation (1):
3(7) + 2b = 33
21 + 2b = 33
2b = 12
b = 6 inches

Fish A is 7 inches long, and fish B is 6 inches long.

Find the length of AC. Round answer to the nearest tenth.

Answers

Answer:

16.0

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

... Tan = Opposite/Adjacent

... tan(32°) = 10/AC

Multiplying by AC and dividing by the tangent gives you ...

... 10/tan(32°) = AC = 16.0

Answer:  The required length of AC is 16.1 units.

Step-by-step explanation:  We are given to find the length of side AC of triangle ABC.

From the figure, we note that

the triangle ABC is a right-angled triangle, where

m∠C = 90°, m∠A = 32° and BC = 10 units.

For the acute angle A, side AC is the base and side BC is the perpendicular.

So, from trigonometric ratios, we have

[tex]\tan m\angle A=\dfrac{perpendicular}{base}\\\\\\\Rightarrow \tan32^\circ=\dfrac{BC}{AC}\\\\\\\Rightarrow \tan32^\circ=\dfrac{10}{AC}\\\\\\\Rightarrow 0.62=\dfrac{10}{AC}\\\\\\\Rightarrow AC=\dfrac{10}{0.62}\\\\\Rightarrow AC=16.13.[/tex]

Rounding to nearest tenth, we get

AC = 16.1 units.

Thus, the required length of AC is 16.1 units.

The table entry (0, 1.5) tells you that the y-intercept is 1.5. That eliminates choices C and D.

Substituting x=4 into the first equation (choice A) shows you it is incorrect:

  y = -5.5(4²) -2.5(4) +1.5 = -88 -10 +1.5 = -96.5 . . . not -60.5

Final answer:

The equation in standard form of the parabola that models the values in the table is y = -2.3x^2 + 2.6x + 1.5

Explanation:

The equation in standard form of a parabola that models the values in the table is y = ax^2 + bx + c. To find the values of a, b, and c, we can use the given table:

XF(x)-22.501.54-60.5

Plugging in the values from the table into the equation, we get a system of three equations:

4a - 2b + c = 2.5

c = 1.5

16a + 4b + c = -60.5

Solving this system of equations, we find that a = -2.3, b = 2.6, and c = 1.5.

Therefore, the equation in standard form of the parabola that models the values in the table is y = -2.3x^2 + 2.6x + 1.5.

Two circles have the same center but different radii. Which of the following is true about the circles? A. They are not similar because they have different radii. B. They are congruent because they have the same center. C. They are congruent because they have the same shape and size. D. They are similar because they are of the same shape but different size.

Answers

Final answer:

Two circles that have the same center but different radii are similar because they share the same shape but differ in size. The answer, therefore, is D. They are similar because they are of the same shape but different sizes.

Explanation:

The question involves two circles that share the same center but have different radii. According to geometric principles, similar figures have the same shape but not necessarily the same size, while congruent figures have both the same shape and the same size. Since the two circles share the same center (co-centric circles) and therefore the same shape (both are circular) yet differ in size, due to their different radii, the correct answer is that they are similar. Hence, the correct option is:

D. They are similar because they are of the same shape but different sizes.

This addresses the concept that similarity in geometry is about shape, rather than size. If the circles were both identical in size and shape, they would be congruent; however, because their sizes vary, they cannot be congruent.

Which ordered pair describes a point that should be removed from the graph so that the graph represents a function.

Answers

Answer:

A

Step-by-step explanation:

Function cannot have at least two points on same vertical line.

Vertical test fails at x = 1. So we need to eliminate either point (1, 1) or (1, 3).

There is option (1, 1), so A.

To represent a function, we must have unique y-values for each x-value. Thus, the point (1,1) should be removed. The correct answer is A).

To determine which ordered pair should be removed from the graph to represent a function, we need to check for uniqueness in the x-values. In a function, each x-value can only be associated with one y-value.

Let's examine the given points:

(1,1)

(3,2)

(5,2)

(7,4)

(1,3)

The x-values are: 1, 3, 5, 7, and 1.

Notice that the x-value 1 is associated with both (1,1) and (1,3). In a function, an x-value should have a unique y-value. Therefore, the point (1,1) should be removed from the graph to represent a function.

So, the correct option is A) (1,1).

What is the Value of this X? i feel like it's 90 just double checking

Answers

Answer:

x=56

Step-by-step explanation:

There are 3 angles in the triangle

x, 60 and the unknown angle we will call y

y  and 2x+4 make a straight line, so that adds to 180

y + 2x+4 = 180

Solve for y

y = 180 - (2x+4)

y = 180 -2x-4

y = 176 -2x


The three angles in a triangle add to 180

x + 60 + y = 180

Substitute in for y

x + 60 + 176 -2x = 180

Combine like terms

-x +236 = 180

Subtract 236 from each side

-x+236-236 = 180-236

-x = -56

Multiply by -1

x = 56
