Answer:

3.3 x - (3.3*8) - x = 1.2

2.3 x - (3.3*8) = 1.2

2.3 x - 26.4 = 1.2

2.3 x - 26.4 + 26.4 = 1.2 + 26.4

2.3 x = 27.6

2.3 x / 2.3 = 27.6 / 2.3

x = 12

Answer:

Step-by-step explanation:

an = 6n - 13

If n  = 10  ,  a10 = 6*10 - 13 = 60-13 = 47

If n  = 11 ,  a11 = 6*11 - 13 = 66-13 = 53

If n  = 12  ,  a12 = 6*12 - 13 = 72-13 =  59

The formula to find the nth term of the sequence an, is a(n) = -13 + 6n

From the question, we have the following parameters that can be used in our computation:

a(10) = 47

a(11) = 53

a(12) = 59

a(13) = 65

The nth term of an arithmetic sequence can be represented as

a(n) = a(1) + (n - 1) * d

Where,

common difference,

d = 6

So, we have

a(n) = a(1) + (n - 1) * 6

Using the 12th term, we have

a(1) + (12 - 1) * 6 = 59

a(1)  = 59 - 66

a(1)  = -7

So,, we have

a(n) = -7 + (n - 1) * 6

Expand

a(n) = -13 + 6n

Hence, the formula to find an is a(n) = -13 + 6n

Answer:

A) The increase population of town after 3 years is 1.2 times initial population

B) The increase population of town after 5 years is 1.4 times initial population .

Step-by-step explanation:

Given as :

The rate of growth of population of a town = r = 7.5%

Let The initial population of town = p

A ) Let The increase population of town after 3 years = P

The time period = n = 3 years

Now, According to question

The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

Or, The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm r}{100})^{\textrm n}[/tex]

Or, The increase population of town after 3 years  = p × [tex](1+\dfrac{\textrm 7.5}{100})^{\textrm 3}[/tex]

Or, P = p × [tex](1.075)^{3}[/tex]

Or, P = p × 1.242

So, The increase population of town after 3 years = P = 1.2 times initial population

Hence,The increase population of town after 3 years is 1.2 times initial population .  Answer

B )  Let The increase population of town after 5 years = P'

The time period = n = 5 years

Now, According to question

The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

Or, The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm r}{100})^{\textrm n}[/tex]

Or,  The increase population of town after 5 years = p × [tex](1+\dfrac{\textrm 7.5}{100})^{\textrm 5}[/tex]

Or, P' = p × [tex](1.075)^{5}[/tex]

Or, P' = p × 1.4356

So, The increase population of town after 5 years = P' = 1.4 times initial population

Hence,The increase population of town after 5 years is 1.4 times initial population . Answer

Final answer:

The cost for 1 3/4 pounds of milk chocolate is $6.25 more than the cost for 1 3/4 pounds of caramels, after calculating the total cost of each based on their per pound price.

Explanation:

To find out how much more the cost for 1 3/4 pounds of milk chocolate is than the cost for 1 3/4 pounds of caramels, we first need to calculate the cost of 1 3/4 pounds of each type of candy. Since the cost per pound of caramels is $10.28 and the cost per pound of milk chocolate is $13.85, we can set up our calculations as follows:

Total cost of caramels = 1.75 (pounds) * $10.28 (per pound) = $17.99

Total cost of milk chocolate = 1.75 (pounds) * $13.85 (per pound) = $24.24

Now, we subtract the total cost of caramels from the total cost of milk chocolate to find the difference:

Cost difference = $24.24 - $17.99 = $6.25

So, the cost for 1 3/4 pounds of milk chocolate is $6.25 more than the cost for 1 3/4 pounds of caramels.

Answer:

18) If ∠1 = 124° , then ∠4 = 56°.

19) if ∠2 = 48°, then ∠3 = 132°.

20) if ∠4 = 55°, then ∠2 = 55°.

21) if ∠6 = 120° , then ∠8= 120°.

22) if ∠7 = 50.5 , then ∠6= 50.5°.

23) if ∠3 = 118.7°, then ∠2= 61.3°

Step-by-step explanation:

Given two parallel lines a and b.

And other line, which is called transversal line cuts these two parallel lines to make 8 angles.

Now,

18) Given, ∠1 = 124°

 Now, sum of consecutive interior angles made by transversal line with parallel lines = 180° .

⇒∠1 + ∠4 = 180°

⇒∠a = 180° - 124° = 56°.

19) ∠2 = 48°.

as sum of consecutive interior angles made by transversal line with parallel lines = 180° .

∠2 + ∠3 = 180°.

⇒ ∠3 = 180° - 48° = 132°.

20) ∠4 = 55°

Alternate angles made by transversal line with parallel lines are equal .

⇒∠2 = ∠4 = 55°.

21) ∠6 = 120°

As corresponding angles made by transversal line with parallel lines are equal. ∠6 = ∠3 = 120°.

now, also opposite angles are equal

⇒ ∠3 = ∠8 = 120°.

22) ∠7 = 50.5

As corresponding angles made by transversal line with parallel lines are equal. ∠7 = ∠2 = 50.5°.

now, also opposite angles are equal

⇒ ∠2 = ∠6 = 50.5°.

23) ∠3 = 118.7°

as sum of consecutive interior angles made by transversal line with parallel lines = 180° .

∠3 + ∠2 = 180°.

⇒ ∠2 = 180° - 118.7° = 61.3°

To find the coordinates of the other endpoint B given the midpoint M and one endpoint A. Apply the midpoint formula and solve the equations to find the coordinates of B(-1, 5).

The midpoint coordinates are given as M(3, -2) and one endpoint is given as A(7, -9). To find the coordinates of the other endpoint, we can use the midpoint formula which states that the coordinates of the midpoint are the average of the coordinates of the two endpoints.

Let the coordinates of the other endpoint be B(x, y). Using the midpoint formula, we have:

[(x + 7) / 2, (y + -9) / 2] = (3, -2)

Simplifying the equation, we get:

(x + 7) / 2 = 3

(y - 9) / 2 = -2

Multiplying both sides by 2, we have:

x + 7 = 6

y - 9 = -4

Subtracting 7 from both sides, we get:

x = -1

Subtracting -9 from both sides, we get:

y = 5

Therefore, the coordinates of the other endpoint are B(-1, 5).

Answer:

The number of dimes is 14 and the number of quarters is 7.

Step-by-step explanation:

Given:

Emily has $3.15 worth of dimes and quarters.

She has twice as many dimes as quarters.

Now, to determine the number of dimes and the number of quarters.

Let the number of quarters be [tex]x.[/tex]

And the number of dimes be  [tex]2x.[/tex]

So, the total worth of dimes and quarters = $3.15.

Now, to get the number of dimes and quarters:

According to question:

[tex]0.10(2x)+0.25x=3.15[/tex]

[tex]0.20x+0.25x=3.15[/tex]

[tex]0.45x=3.15[/tex]

Dividing both sides by 0.45 we get:

[tex]x=7.[/tex]

Thus, the number of quarters = 7.

So, the number of dimes = [tex]2x=2\times 7=14.[/tex]

Therefore, the number of dimes is 14 and the number of quarters is 7.

Note: As you missed to mention the graph for f(x) = x + 1 from where we had to check which option defines the accurate graph. But, after a little research, I was able to get the graph of this question, and hence attaching the graph. So, I am answering based on that graph which, anyways, would clear your concept about determining the domain of the function that shows in a graph.

Answer:

x > 1 is the domain of the f(x) = x + 1.

Step-by-step explanation:

A domain is the set of all x values that a function passes through. It means a domain is set of all input values where the function is defined, meaning whatever you input the x value, for every x-value there is only one y-value that corresponds to it.

So, now lets talk about the given function f(x) = x + 1 and its graph as shown in attached figure. Carefully observe the top right part of the graph of f(x) = x + 1. It is validating the condition of x > 1.

For example,

Just input some x values, greater than 1 i.e. x > 1, in f(x) = x + 1 to determine the output values.

For example, for x > 1

and so on.

So, the top right part of the graph of f(x) = x + 1 is validating the condition of x > 1 as it is passing through P(2, 3), P(3, 4) and P(4, 5) etc. and so on.

So, x > 1 is the domain of the f(x) = x + 1.
