The formula = 21+ 2m is used when calculating:
a area of a rectangle
C area of a circle
b. perimeter of a rectangle
d circumference of a circle

Step-by-step explanation:

Let the smallest angle be x

2nd angle = 2x

3rd angle = 9x

By angle sum property

x+2x+9x=180°

x=180/12

x=15

Three angles are 15, 30 and 135

Answer: She needs 6 packs of cookies and  5 packs of coffee sachets.

Step-by-step explanation:

Cookies: come in packs of 10

Coffee sachets: come in packs of 12.

Sally wants to sell them in groups of 1 cookie and 1 coffee sachet, then we need to find a common multiple of 10 and 12. (the smallest one in this case).

To find the smallest common multiple, first let's find the largest common factor between 10 and 12.

If we write the numbers as a product of prime numbers, we have:

10 = 2*5

12 = 2*3*3

The only common factor is 2.

Then the smallest common multiple between 10 and 12 is equal to the product of 10 and 12 divided by the largest common factor between them, in this case is 2.

M = 10*12/6 = 60

Now to find the number of packages of each thing that she must buy, we need to divide 60 by the number of elements in each pack.

Cookies: 10 per pack

60/10 = 6

She needs 6 packs of cookies

Coffe: 12 per pack

60/12= 5

She needs 5 packs of coffee sachets.

Answer:

(1, 6), (2, 8), (3, 10)

2(1) + 4 = 6, 2(2) + 4 = 8 and 2(3) + 4 = 10.

Step-by-step explanation:

The set of inputs for the equation f ( x ) = 2x + 4 is

( 1 , 6 ) , ( 2 , 8 ) , ( 3 , 10 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be f ( x ) = 2x + 4

f ( x ) = y

Now ,

Let the first point be A ( 1 , 6 )

Let the second point be B ( 2 , 8 )

Let the third point be C ( 3 , 10 )

a)

A ( 1 , 6 )

Substitute the value of x and y in the equation , we get

y = 2x + 4

6 = 2 ( 1 ) + 4

6 = 2 + 4

6 = 6

Hence , the input A ( 1 , 6 ) satisfies

b)

B ( 2 , 8 )

Substitute the value of x and y in the equation , we get

y = 2x + 4

8 = 2 ( 2 ) + 4

8 = 4 + 4

8 = 8

Hence , the input B ( 2 , 8 ) satisfies

c)

C ( 3 , 10 )

Substitute the value of x and y in the equation , we get

y = 2x + 4

10 = 2 ( 3 ) + 4

10 = 6 + 4

10 = 10

Hence , the input C ( 3 , 10 ) satisfies

Hence , The set of inputs for the equation f ( x ) = 2x + 4 is

( 1 , 6 ) , ( 2 , 8 ) , ( 3 , 10 )

24 - 8 + 8/3 - 8/9 + 8/27 - 8/81

First division

8/3 = 2.66666666667

8/9 = 0.88888888888

8/27 = 0.29629629629

8/81 = 0.09876543209

Then Subtract

24 - 8 = 15

2.66666666667 - 0.88888888888 = 1.77777777779

0.29629629629 - 0.09876543209 = 0.1975308642

Then lastly add

15 + 1.77777777779 + 0.1975308642 = 16.975308642

In these type of questions, the answer have decimals, so we have to round it to near whole number.

So nearest whole number is 17

Answer:

A function is a relationship that maps the elements of a set, the domain, into elements of another set, the range.

The restriction that we have for functions is: The elements on the domain can be mapped into only one element in the range.

Then if:

f(x1) = y1

and

f(x1) = y2

where y1 is different than y2

f(x) is not a function.

Now, in the graph you can see a region where both lines overlap, then for some values of x we have two possible values of y, this means that the graph does not represent a function.

Then:

Ed: He is incorrect because we can have different values in the domain mapped into the same value in the range (like in the case of a line y = b, where we have all the elements in the domain mapped into the same element in the range, b)

Debra: There is something called piecewise functions, that are functions of this type, formed by different pieces.

Alejandro: He is correct.

Antoine: Not because you can write an equation means that the relation is a function. You can write an equation for a circle, but it will not be a function.

Answer:

This number would be straight out zero  .

Step-by-step explanation:

First it said the quotient of fifty and five MORE than a number is 10, so we first need to focus on the line five MORE than a number is 10, so we know this number is less than the value used in the equation then we focus on the quotient of fifty and, So we know this unknown number lets just say the variable for it is n, then we know that fifty/ n+5=10. So Lets use the associative property to turn this into and some algebra to fifty/10 = n+5, so 50/10 equals to 5, so we know that, 5= n+5, so that would be... n =  0. Hope this helps you answer your question! :)

Answer:

um 3 5/4

Step-by-step explanation:

The distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]

So, we will use the distance formula:

Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂).

Now Substitute:

D = √[(1 - (5/2))² + (8/3 - 2)²]

Evaluate the expressions within the parentheses;

D = √[(1 - (5/2))² + (8/3 - 2)²]

D = √[(-3/2)² + (2/3)²]

Evaluate:

D = √[9/4 + 4/9]

Square:

D = √97/6

Hence, the distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.
