Answer:

6

Step-by-step explanation:

No exact amount of cookies so if its a large batch we'll say there is 45 cookies 45 divided by 1/3 is 15

So 15 divided by 2 1/2 = 6

So your answer is 6.

Answer:

60

Step-by-step explanation:

all angles in an equilateral triangle equal 60 because 180 ÷ 3 = 60

Answer:

60 degrees

Step-by-step explanation:

each angle in a triangle adds up to 180 so 180/3 equals 60

Step-by-step explanation:

An equation that represents the relationship between d and m can be written as d = 1.25 m.

Speed of an object is the rate of change of position of an object in any direction.

Speed is a scalar quantity because it does not have any direction, it only has magnitude. Speed with direction is called velocity.

The formula for calculating speed is,

Speed = Distance / Time

Given distance the train travelled = 7 [tex]\frac{1}{2}[/tex] kilometers

                                                        = 15/2 kilometers

                                                        = 7.5 kilometers

Time taken to travel the distance = 6 minutes

Speed = 7.5 / 6

           = 1.25 kilometers / minute

Given that speed of the train is constant.

Hence for any distance 'd' kilometers in 'm' minutes,

d / m = 1.25

d = 1.25m

Hence d and m can be related by the equation d = 1.25m.

Step-by-step explanation:

7. f(x)=0.2x

8. f(x)=3x+5

9. f(x)=-2x-2

According to the tables, the linear functions are given by:

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

Item 7:

From x = -3 to x = 1, when x changes by 4, y changes by 0.8, hence the slope is:

[tex]m = \frac{0.8}{4} = 0.2[/tex].

Then:

[tex]y = 0.2x + b[/tex]

When x = 1, y = 0.2, which is used to find b. Hence:

[tex]0.2 = 0.2 + b[/tex]

[tex]b = 0[/tex]

Hence, [tex]y = 0.2x[/tex].

Item 8:

From x = -5 to x = -2, when x changes by 3, y changes by 9, hence the slope is:

[tex]m = \frac{9}{3} = 3[/tex].

Then:

[tex]y = 3x + b[/tex]

When x = 4, y = 17, which is used to find b. Hence:

[tex]17 = 3(4) + b[/tex]

[tex]b = 5[/tex]

Hence, [tex]y = 3x + 5[/tex].

Item 9:

From x = -5 to x = -2, when x changes by 3, y changes by -6, hence the slope is:

[tex]m = \frac{-6}{3} = -2[/tex].

Then:

[tex]y = -2x + b[/tex]

When x = 8, y = -18, which is used to find b. Hence:

[tex]-18 = -2(8) + b[/tex]

[tex]b = -2[/tex]

Hence, [tex]y = -2x - 2[/tex].

Answer:

The common difference is same = d = -9

Therefore, the data represent a linear function.

Step-by-step explanation:

Given the table

x                        y

1                         4

2                        -5

3                        -14

4                        -23

5                         -32

Finding the common difference between all the adjacent terms of y-values

d = -5 - 4 = -6,

d = -14 - (-5) = -14+5 = -9

d = -23 - (-14) = -23 + 14 = -9

d = -32 - (-23) = -32 + 23 = -9

It is clear that the common difference between all the adjacent terms is same.

Thus,

d = -9

We know that when y varies directly with x, the function is a linear function.

Here, it is clear that each x value varies 1 unit, and each y value varies -9 units.

i.e. The common difference is same = d = -9

Therefore, the data represent a linear function.
