Answer:

(x-1)!

Step-by-step explanation:

lets say you want to sit x people around a table you would do x!. but since it doesn't count if you rotate the table you have to divide it by x, so the answer is x!/x = (x-1)!

Answer:

Solving for x:

[tex]x = \frac{3}{2} y + 9[/tex]

Solving for y:

Answer:

Step-by-step explanation:

Perimeter= 46

Area of rectangle= Length * Width

Ratio                    =       2 : 1

= Length= 2/3 * 46 = 30.6/2 = 15.3

Width = 1/3 * 46 = 15.3/2 = 7.65

Area= 117.045

j = 13

7×j = 91

j = 91 : 7

j = 13

Answer: she would need four and a half cups more of sugar.

Step-by-step explanation:

You have to add together all of them sugar she would have needed so (1 1/4 times 4) and then subtract what she already had and that gives you 4 and 1/2 cups she would need. Hope this helps

Answer: 4 and 1/2

Step-by-step explanation:

You add together all of the sugar that she would have needed which is 1 1/4 * 4 and then subtract what she already had before which would give you 4 and 1/2 cups she would need.

Answer:

I'm fairly sure its 4.93 grams.

Step-by-step explanation:

you take the origional water of 45.1ml and the new 52.3ml, and find the difference, which in this case is 7.2ml.

the density formula is D=M/V

D= Density

M=Mass

V=Volume

so it would be

D= 35.49/7.2

which is 4.93.

again this is just from what I remember of science class.

Answer: 4.93g/cm^3

Step-by-step explanation:

Formula for Density: D = mass / volume

We know that the mass of the unknown object is 35.49g

Mass = 35.49g

To find the volume

Initial water level: 45.1 mL

Final water level: 52.3mL

52.3cm^3 - 45.1cm^3 = 7.2cm^3

Volume = 7.2cm^3

Density = 35.49g/7.2^3

Density =

Answer: A) 23

Step-by-step explanation:

3^2 + ( 6 - 2 ) ⋅ 4 -6/3

3^2 + 4 ⋅ 4 -6/3

9 + 4 ⋅ 4 -6/3

9 + 16 -6/3

25 - 6/3

75/3 -6/3 = 69/3

69/3 = 23

Answer:

23

Step-by-step explanation:

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

3^2 + 4 x 4 - 6/3

9 + 16 - 6/3

25 - 6/3

6/3 = 2

25 - 2 = 23

Answer:

n/(4-5)

Step-by-step explanation:

A quotient of a number and... means that the number is being divided by whatever comes after. In this case the number that comes after is '4 decreased by 5', which is 4 - 5 as the -5 takes 5 away so it 'decreases it by 5'. Therefore is the expression is 'the quotient of a number and four decreased by five' then it is expressed in the following way (using n for number):

n/(4-5)

Answer:

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

The smallest angle for which -0.25 is the tangent is in the  second quadrant and is 165.96 degrees. The other angle in the fourth quadrant is 345.96 degrees.

So for the range 0 to 720, x = 165.96, 345.96 and  360 + 165.96 = 525.96 and 345.96+360 = 705.96 degrees.

Answer:

 75°C = 5h

Step-by-step explanation :

1. Make sure your mind is fresh and that you understand each step before reading

2. 24 hours is equal to  360°C

3.  so now lets break up the hours. We can do this by choosing a simple degree that was given in the diagram. For example "Watching tv".

Tip : when choosing one of the degrees , ( i mean one of the choices like watching tv, playing and sleeping) , try choosing the simplest one , which has a simple number and a multiple of 360.

so now you want to know how many hours is 60 equal to .

= 360 ÷ 60 = 60   (this is to make sure the number is a multiple and will not be a decimal )

= 24 ÷ 6 = 4

this means Ali spend 4 hours watching tv

and by doubling that you get                    60°C = 4h

the amount of time he slept                     120°C = 8h

and you keep playing with the numbers like that

so for playing                                                

                                                                   60°C = 4h

                                             divide by 4    15°C =  1h

                                           × by 5             75°C = 5h

this means ali spends 5h playing , 8h sleeping, 4h watching tv and 7 h studding

Answer:

The Communitive Property of Addition

Step-by-step explanation:

The properties are

Communitive: You can switch the order and still get the same answer

Assosiative: You can switch what numbers are in the parentheses and still get the same answer (if you're only adding) a+(b+c)=c+(a+b)

Distributive: (a*b)+(a*c)=a*(b+c)

Identity: You can add a number with 0 and get the same number you started with

y+x=x+y is the communitive property because, no matter which order the numbers are, you get the same answer

Answer:

20 people

Step-by-step explanation:

The first step is to find out how many people are in 1/7 of the group. To do this, we divide 28÷7, and our answer is 4.

28÷7=4

Our next step is to find out how many people are in 2/7 of the group. We would double the 4, since 1/7 doubled is 2/7, and get 8.

4 x 2= 8

Now we know that 8 people ordered ice cream. To find the number of people who ordered the special, we subtract 8 from 28.

28-8= 20

Therefore, 20 people ordered the special. Hope this helps!

If 28 people ordered dessert, 2/7 ordered ice cream then 20 people ordered the rest.

Two or more expressions with an Equal sign is called as Equation.

Given that 28 people ordered dessert.

2/7 ordered ice cream and the rest ordered the special how many people ordered the special.

1/7 of the 28 people is 4.

Our next step is to find out how many people are in 2/7 of the group. We would double the 4, since 1/7 doubled is 2/7, and get 8.

4 x 2= 8

we know that 8 people ordered ice cream.

To find the number of people who ordered the special, we subtract 8 from 28.

Twenty eight minus eight equal to twenty.

28-8= 20

Hence, 20 people ordered the special.

Answer:

4x^2-9

Step-by-step explanation:

i just took the quiz

This is about greatest Common factor (G.C.F) thus Option C and Option D does not have a greatest common factor.

The Greatest common factor between 2 or more numbers is simply the greatest factor that is common to all the numbers.

Option A; 2x² -18

Factors of 2 are 1, 2

Factors or 18 are; 1, 2, 3, 6, 9, 18

In this option we can see that 2 is the only common factor between all the numbers.

Thus, the GCF = 2 So this has a GCF

Option B: 3x² + 12x + 6

Factors of 3 are 1, 3

Factors of 6 are 1, 3. 6

Factors or 12 are; 1, 2, 3, 4, 6, 12

The highest common factor is 3 Thus, this has GCF.

Option C; 4x² - 9

The factors of 9 are; 1, 3, 9

The factors of 4 are; 1, 2, 4

Since there is no highest common factor here as 1 is not considered to be a highest common factor even though it is a factor.

Option D; 6x² +  2x² + 5x

The factors of 9 are; 1, 3, 9

The factors of 4 are; 1, 2, 4

Since there is no highest common factor here as 1 is not considered to be a highest common factor even though it is a factor.
