Answer:

The correct answer is 4,672.18.

Step-by-step explanation:

To solve this problem, we must look at the number we are given and determine what numbers are in which places.  The 4 is in the thousands place, the 6 is in the hundreds place, the 7 is in the tens place, the 2 is in the ones place, the 1 is in the tenths place, the 8 is in the hundredths place, and the 3 is in the thousandths place.  

The question asks us to round to the nearest hundredth, so this means that the number in the hundredths place should be the final digit.  In the number given, the number 8 is in the hundredths place.  Since the following digit (3) is less than 5, we round down and keep the 8 in the hundredths place.  This makes our answer 4,672.18.

Hope this helps!

y=5

Step-by-step explanation:

all you have to do is divide 6 on both sides

to get 5 cause negatives cancel

y = 5

Step-by-step explanation:

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

A hexagon has six sides. Since it is a regular hexagon, all of the sides have equal length, so we can multiply the length of one side, 3.6 by 6 to get the perimeter. 3.6 x 6 = 21.6. To the nearest centimeter, the upper bound is 22.

Answer:

Infinite Solutions

Step-by-step explanation:

6x+6=6(x+1)

6x+6=6x+6

If both sides of the equations are equal, it will ALWAYS be infinite solutions:)

Answer:

Infinite solutions.

Step-by-step explanation:

You have to distribute the 6 to the x and the 1. You'll then realize that both sides have 6x+6, and since 6x-6x=0 and 6-6=0,  If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions.

Answer:

For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.

Since, we know, that the sum of all angles of any triangle be 180° .

Let each angle be a.

Thus,

Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Answer:

22

Step-by-step explanation:

Step 1:

- 12x + 18 - 10x - 5 = - 31

Step 2:

- 22x + 18 - 5 = -31

Step 3:

- 22x + 13 = - 31

Step 4:

- 22x = - 44

Answer:

x = 22

Hope This Helps :)

Answer:

Your answer is x = 2

Step-by-step explanation: [tex]-12x + 18-10x-5 = -31[/tex]

subtract 18 - 5 = 13 and add -12x+(-10x)= -22x

[tex]-22x+13=-31[/tex] subtract 13 on both sides

[tex]-22x+13(-13)=-31(-13)[/tex]  cross out +13(-13) and -31-13= -44

[tex]-22x=-44[/tex] divide -22 on both sides

[tex]\frac{-22x}{-22} = \frac{-44}{-22}[/tex] cross -22x/-22 and divide -44 and -22= 2

[tex]x = 2[/tex]

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(6,4) and (-5,-1)

The distance between them is

[tex]d = \sqrt{ ({6 + 5})^{2} + ( {4 + 1})^{2} } \\ = \sqrt{ {11}^{2} + {5}^{2} } \\ = \sqrt{121 + 25} \\ = \sqrt{146} \\ \: \: \: \: \: \: \: \: \: \: \: = 12.0830459[/tex]

Answer:

V/(2tr)=h

I think, its been a while since i had to do a problem like this

Answer: (f•g)(x)=​2x²+12x

Step-by-step explanation:

(f•g)(x) is the same as saying f(x)•g(x). Since we have f(x) and g(x), we can just multiply them together.

(f•g)(x)=​2x(x+6)                [distribute by FOIL]

(f•g)(x)=​2x²+12x              

Now, we know that (f•g)(x)=​2x²+12x.

The value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.

The formula to convert a temperature from Kelvin K to Fahrenheit F is,

[tex]F=95(K-273.15)+32[/tex]

Here, K is Kelvin and F is Fahrenheit.

Solve the formula for K in the following way,

[tex]F=95(K-273.15)+32[/tex]

Subtract 32 both side,

[tex]F-32=95(K-273.15)+32-32\\F-32=95(K-273.15)[/tex]

Divide, with 95, both side of equation,

[tex]\dfrac{F-32}{95}=(K-273.15)\\\dfrac{F-32}{95}=K-273.15\\\dfrac{F-32}{95}+273.15=K[/tex]

This is the solved equation for K.

To convert 240∘ F to Kelvin K, put the value in the formula given in above equation,

[tex]\dfrac{F-32}{95}+273.15=K\\\dfrac{240-32}{95}+273.15=K\\\dfrac{208}{95}+273.15=K\\2.12+273.15=K\\275.27=K\\K\approx 275[/tex]

Thus, the value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.
