Answer:

Decagon

Step-by-step explanation:

We can use the general equation to determine the sum of interior angles:

[tex]I.A. = 180 \times (n-2)[/tex]

Since we know the sum of interior angles (I.A.) is 1440°, we must figure out n - the number of sides and so:

[tex]1440=180(n-2)\\\\\frac{1440}{180}=n-2\\\\8=n-2\\\\n=10[/tex]

Since n=10 this means that it is a 10 sided shape meaning it's a decagon.

Answer:

decagon

Step-by-step explanation:

1440=180(n-2)

8=n-n

n=10  

this means that your answer is going to is decagon.

Answer:

1 : √3 : 2

Step-by-step explanation:

In the special right triangle, 30°-60°-90° triangle:-

Opposite side < Adjacent side < Hypotenuse.

1. The smallest side is opposite to angle 30°, also called opposite side.

2. Adjacent side is √3 times smallest side.

3. Hypotenuse is 2 times smallest side.

So the ratios of sides would be as follows:-

Opposite : Adjacent : Hypotenuse

1x : √3x : 2x

1 : √3 : 2

Answer:

The answer is a. 3x - y = -11

Step-by-step explanation:

Firstly, you must find the gradient. This is found using the following formula:

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

Make sure that the x2 and y2 values are in the same coordinate set:

Let's set (-3 , 2) as y1 and x1,

y1 = 2 and x1 = -3

That means that (-5 , 8) is y2 and x2,

y2 = 8 and x2 = -5

Plug the values in:

[tex]\frac{8 - 2}{-5 - - 3}[/tex]

Simplified:

[tex]\frac{6}{2}[/tex]

Or 3

So the gradient (or slope) is 3

Now, using the following equation of a line formula:

y - y1 = m(x - x1)

Where m is the gradient and y1 and x1 are two coordinates, we can plug these values in:

y1 = 2

x1 = -3

m = 3

y - 2 = 3(x - - 3)

The negative and the subtract makes it a positive:

y - 2 = 3(x + 3)

Now we can multiply the bracket out:

3 * x = 3x

3 * 3 = 9

So:

y - 2 = 3x + 9

The equation is usually in the form:

y = mx + c

So we need to move the -2 over to the other side making it a positive 2:

y = 3x + 9 + 2

y = 3x + 11

Which is the equation of the line.

The one option that this rearranges to is a) because if you move the y over to the 3x, and the + 11 over to the other side, making them both negatives, the result is:

3x - y = -11

So your answer is a.

240,000/100=2,400.

Answer:

Option A is correct.

1,017.36 square feet does the base of the building measure.

Step-by-step explanation:

Given: Diameter of the base (d) = 36 feet , Height of the building (h) = 57.2 feet and slant height of the building(l) = 60 feet.

We have to find the area of the base of the building.

Since, the building is in the form cone.

Area of the base(A) of the cone is given by:

[tex]A= \pi r^2[/tex] ......[1]; where r is the radius of the cone

Diameter(d) = 2r

36 = 2r

Divide both sides by 2 we get;

r = 18 feet.

Substitute the value of r = 18 feet and [tex]\pi = 3.14[/tex] in [1] we get;

Area of the base of the building = [tex]3.14 \times (18)^2 = 3.14 \times 324 = 1017.36[/tex] square feet.

Therefore, 1,017.36 square feet does the base of the building measure.

Step-by-step explanation:

I'll do the first one to get you started

So we have g(f(x)) which means that we start with g(x) and replace the 'x' with 'f(x)' to get g(f(x))

g(x) = ( x - 4 )/2

g(f(x)) = ( f(x) - 4)/2 .... replace every x with f(x)

g(f(x)) = (2x+4-4)/2 .... replace f(x) on the right side with 2x+4

g(f(x)) = (2x+0)/2

g(f(x)) = (2x)/2

g(f(x)) = 1x/1

g(f(x)) = 1x

g(f(x)) = x

Answer:

Number of cows is 23

Number of chickens is 46

Step-by-step explanation:

Let's assume

number of cows =x

we are given

Mr.Yan has almost as twice as many chickens and cows

so,

Number of chickens =2x

We know that

Number of legs in a cow =4

Number of legs in a chicken =2

now, we can set up equation

[tex]4\times x+2\times 2x=184[/tex]

[tex]4x+4x=184[/tex]

[tex]8x=184[/tex]

[tex]x=23[/tex]

So,

Number of cows =23

Number of chickens is

Step-by-step explanation:

Answer:

tax = $6.63

Step-by-step explanation:

We can find the tax by multiplying the original amount by the tax rate.

tax rate = 10 % = .1

tax = 66.30 * .10

     = 6.63

To solve this problem, we need to figure out how much tax Peter will be paying, given that the tax rate is 10% and his purchase costs $66.30.

To do this, we must first convert 10% into a decimal.  To do this, we must divide it by 100 (because it is a fraction out of a total of 100 percent), or simply move the decimal point two places to the left.  Therefore, 10% = 0.10.

To find the tax amount, we must multiply the sales tax rate (10% or 0.10) by the purchase cost ($66.30).  This gives us:

$66.30 * 0.10 = $6.63

Therefore, your answer is $6.63.

(A little tip: the method I used above can be used for any tax rates, but a trick for finding 10 percent of something is to move the decimal point of the cost one place to the left).

Answer:

Step-by-step explanation:

(a) Carl earns $42 per 3 hours as given. To find the amount he earns per hourdivide:

$42/3 hours = $14/hour

(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:

y = $11(1 hours)

y = $11/hour

Thus Carl makes more than Louis.

(c) The equation of Carl's dollars per hour is similar to Louis' = 14x 

where x is the number of hours he works and y is the number of dollars he earns. Plug in whole number values of hours for x and plot the points (x, y) on a graph

Is him in your bias?

Carl earns $14 per hour, which is more than Louis' hourly wage of $11. A graph that represents Carl's earnings should have time in hours on the x-axis and money earned on the y-axis.

The question relates to comparing Hourly Earnings of Louis and Carl, and analyzing earnings overtime through graphs.

(a) To determine Carl's hourly earnings, we divide the amount of money earned by the hours worked.

For example, when he works 3 hours, he earns $42.

Therefore, the hourly rate is $42/3 = $14 per hour.

(b) By comparing Carl's hourly earning which is $14/hour to Louis' earning which is $11/hour according to the equation y = 11x, it is clear that Carl earns more per hour.

(c) To plot the graph for Carl's earnings, you need to put the time in hours on the x-axis and the money earned on the y-axis.

Each point on the graph represents the amount Carl earns after a certain number of hours.

For example the point (3,42) represents that Carl earns $42 after 3 hours of work.

Answer:

[tex]F(x)=2\left(x+\dfrac{13}{4}\right)^2-\dfrac{9}{8}.[/tex]

Step-by-step explanation:

Consider the function [tex]F(x)=2x^2+13x+20.[/tex]

Rewrite it as follows:

[tex]F(x)=(2x^2+13x)+20=2\left(x^2+\dfrac{13}{2}x\right)+20=2\left(x^2+\dfrac{13}{2}x+\left(\dfrac{13}{4}\right)^2-\left(\dfrac{13}{4}\right)^2\right)+20=2\left(x^2+\dfrac{13}{2}x+\dfrac{169}{16}\right)-2\cdot \dfrac{169}{16}+20.[/tex]

Since

[tex]x^2+\dfrac{13}{2}x+\dfrac{169}{16}=\left(x+\dfrac{13}{4}\right)^2,[/tex]

you get

[tex]F(x)=2\left(x+\dfrac{13}{4}\right)^2+20-\dfrac{169}{8}=2\left(x+\dfrac{13}{4}\right)^2-\dfrac{9}{8}.[/tex]
