4560/x=100/11

(4560/x)*x=(100/11)*x       - we multiply both sides of the equation by x

4560=9.09*x       - we divide both sides of the equation by (9.09) to get x

4560/9.09=x

501.6=x

x=501.6

Hello!

When multiply binomials together, we should use the FOIL method.

The FOIL method is an acronym for First, Outer, Inner, and Last.

First, let's set up the expression.

(7x - 1)(3x - 2)

Now, we can multiply in accordance with the FOIL method.

First: 7x · 3x = 21x²

Outer: 7x · -2 = -14x

Inner: -1 · 3x = -3x

Last: -1 · -2 = 2

Now, we simplify the inner terms.

21x² - 14x - 3x + 2

21x² - 17x + 2

Therefore, the area of the rectangle is 21x² - 17x + 2.

The area of the rectangle is (21x² - 17x + 2) units².

A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.

Given the length of the rectangle is (7x-1) units, while its breadth is (3x-2) units. Therefore, the area of the rectangle is,

Area of rectangle = (7x-1) units × (3x-2) units

= 21x² - 14x - 3x + 2

= 21x² - 17x + 2 units²

Hence, the area of the rectangle is (21x² - 17x + 2) units².

Answer:

Unfortunately, your answer is not right.

Step-by-step explanation:

The functions whose graphs do not have asymptotes are the power and the root.

The power function has no asymptote, its domain and rank are all the real.

To verify that the power function does not have an asymptote, let us make the following analysis:

The function [tex]y = x ^ n[/tex] , when x approaches infinity, where does y tend? Of course it tends to infinity as well, therefore it has no horizontal asymptotes (and neither vertical nor oblique)

With respect to the function [tex]y= \frac{1}{x}[/tex] we ​​can verify that if it has asymptote horizontal in y = 0. Since when x approaches infinity the function is closer to the value 0.

For example: 1/2 = 0.5;   1/1000 = 0.001;    1/100000 = 0.00001 and so on. As "x" grows "y" approaches zero

Also, when x approaches 0, the function approaches infinity, in other words, when x tends to 0 y tends to infinity. For example: 1 / 0.5 = 2; 1 / 0.1 = 10; 1 / 0.01 = 100 and so on. This means that the function also has an asymptote at x = 0

Using the calculator angle whose cos  is 0.9511 is  18 degrees

Sine of the complementary angle = 0.9511 also

Step-by-step explanation:

The sine of the complementary angle( which is 90-18 = 72 degrees) is same value  0.9511

Answer: 18 degrees and 0.9511

Step-by-step explanation:

18°; 0.9511

Cos-1(0.9511) = 18°

The complement of 18° is 72°. The sine of 72° is the cos of 18°, which is 0.9511.

Multiplying a number by 10 simply means to add a 0 at the end of the number, or to shift the decimal separator one unit to the right. So, for example,

[tex] 3 \cdot 10 = 30,\ -152 \cdot 10 = -1520,\ 25.467 \cdot 10 = 254.67 [/tex]

So, in your case, you have to add a 0 at the end of 6000, obtaining

[tex] 6000 \cdot 10 = 60000 [/tex]

Answer:

Domain ={0,infinity)

Range = (-infinity, 4]

Step-by-step explanation:

Given a graph with curve which has y intercept 4.

It passes x axis at 4 and extends fully

The domain is the set of values x can take

In the graph horizontal axis is x axis.

Hence from the graph we see that x can take values from 4 including 4 upto infinity.

Hence domain is x>=4

For range, we consider the values of y as per graph.

WE find that y is not taking values >4

Hence Range = (-infty, 4]

Answer:

[tex]Domain=[0,\infty)[/tex]

[tex]Range=(-\infty,4][/tex]

Step-by-step explanation:

We need to find the domain and range of the function.

Domain : It is the set of input values or x values. In a graph, domain of the function represented by the x-axis.

Range : It is the set of output values or y values. In a graph, range of the function represented by the y-axis.

From the given graph it is clear that it is defined for [tex]0\le x<\infty[/tex] and [tex]-\infty <y\le 4[/tex].

We have closed circle at (0,4). It means, 0 is included in the domain and 4 is included in the range.

[tex]Domain=[0,\infty)[/tex]

[tex]Range=(-\infty,4][/tex]

Therefore, [tex]Domain=[0,\infty)[/tex] and [tex]Range=(-\infty,4][/tex].

Worth of Tim's house in 2018 = 146410 $

Explanation:

Worth of house in 2014 =  $100000

Raise in worth per year = 10 % = 0.1

Worth of house in 2015 = 100000 + 0.1 * 100000 = 110000 $

Worth of house in 2016 = 110000 + 0.1 * 110000 = 121000 $

Worth of house in 2017 = 121000 + 0.1 * 121000 = 133100 $

Worth of house in 2018 = 133100 + 0.1 * 133100 = 146410 $

So, worth of Tim's house in 2018 = 146410 $

Easy Method;

   No of years considering = 4

   Initial worth = $100000

   Rate of increase = 0.1

   Final worth  [tex]=100000(1+0.1)^4=146410$[/tex]

Worth of Tim's house in 2018 = 146410 $

The value of Tim's house at the start of 2018 will be $ 146,410.

Given that at the start of 2014 Tim's house is worth $ 100000, and the value of the house increase by 10% every year, to determine the value of his house at the start of 2018 the following calculation must be performed:

Therefore, the value of Tim's house at the start of 2018 will be $ 146,410.

The equation [tex]35x+93\frac{3}{4} =190[/tex] gives average time spent on 35 rehearsals.

Step-by-step explanation:

We are supposed to find that what question does the equation [tex]35x+93\frac{3}{4} =190[/tex] finds answer of.

We can see that 35x represents time spent on 35 rehearsals and [tex]93\frac{3}{4}[/tex] is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.

Now let us solve our equation step by step.

[tex]35x+\frac{375}{4} =190[/tex]

After subtracting [tex]93\frac{3}{4}[/tex] hours from 190 hours we will get time spent on 35 rehearsals.

[tex]35x =190-\frac{375}{4}[/tex]

[tex]35x =\frac{760-375}{4}[/tex]

[tex]35x =\frac{385}{4}[/tex]

Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.

[tex]x =\frac{96.25}{35}=2.75[/tex]  

Therefore, equation [tex]35x+93\frac{3}{4} =190[/tex] finds average time spent on 35 rehearsals.

Option D

Step-by-step explanation:

From the graph we find that the graph runs only in the I quadrant.

Hence x,y are positive only

Next is y intercept = 2500 and y increases continuously after that.

This implies y >=2500

Hence range is C>2500

Domain is the no of jars of peanut butter.

Hence j>0

In other words, 2500 is the fixed cost even when there is no production and cost cannot be less than 2500 at any time.

Production can be any number of jars from 0 onwards.

Hence option D

Answer:

(x - 2) is not a factor of f(x)  = 3x^5 - 7x^3 -  11x^2 + 2

Step-by-step explanation:

According to the Remainder Theorem, when a polynomial f(x) is divided by a term (x - r), then the remainder must be f(r).

So first we will divide f(x) by (x - 2) using long division to get:

(3x^5 - 7x^3 -  11x^2 + 2) / (x - 2)

= 3x^4 + (6x^4 - 7x^3 - 11x^2 + 2) / (x-2)

= 3x^4 + 6x^3 + (5x^3-11x^2+2) / (x - 2)

= 3x^4 + 6x^3 + 5x^2 (-x^2 + 2) / (x - 2)

= 3x^4 + 6x^3 + 5x^2 -x -2 - (2) / (x -2)

= [tex]\frac{-2 + 3x^{5} - 7x^{3} - 11x^{2} + 2x}{x - 2} - 2[/tex]

Therefore the remainder is -2.

Now check x = 2 for 3x^5 - 7x^3 -  11x^2 + 2:

3(2)^5 - 7(2)^3 -  11(2)^2 + 2 = -2

The Remainder Factor theorem also states that if (x - r) is a factor of f(x) then f(r) must be 0.

So we found that f(2) = -2, therfore (x - 2) is not a factor of f(x) .

Answer:

Gregory will catch up Efren after 26 minutes 40 seconds.

Explanation:

 Distance traveled = Speed x Time

 Speed of Efren = 4 mi/h

 Speed of Gregory = 8.5 mi/h

 Let the time of catch up be t hours.

 Time of journey of Efren before catch up = (t+0.5)hours, since he starts before half hour.

 Distance traveled by Efren = 4 x (t+0.5) miles

 Time of journey of Gregory before catch up = t hours.

 Distance traveled by Gregory = 8.5 x t miles

If they catch up the distance traveled by them is same, so equating both distances.

4 x (t+0.5) = 8.5 x t

4.5t = 2

t = 0.44 hours =26.67 minutes = 26 minutes 40 seconds.

So Gregory will catch up Efren after 26 minutes 40 seconds.

Gregory will catch up to Efren approximately at 9:56am.

To find out when Gregory will catch up to Efren, we need to set up an equation based on their speeds and the time they travel.

Calculate the head start distance: Efren leaves at 9am and walks at 4 miles per hour.

Determine their relative speed: Gregory runs at 8.5 miles per hour while Efren walks at 4 miles per hour.

Calculate the time for Gregory to catch up: We need to divide the head start distance by their relative speed.

Find the catch-up time: Gregory leaves at 9:30am, so add the catch-up time to this.

Therefore, Gregory will catch up to Efren at approximately 9:56am.

Answer:

Each of them get 365.

Explanation:

Total income =  1820

Total expense = 360

Total profit = Total income - Total expense = 1820 - 360 = 1460

Number of persons sharing the profit = 4

Profit got by each person = Total profit/ number of persons sharing profit

                           = 1460/4 = 365

So each of them get 365.
