If she adds songs new in constant amount like 2 per week

Then it will form an arithmetic sequence.

Answer:

[tex]f(w)=116+4w[/tex]

Step-by-step explanation:

Iris has 120 songs on her playlist.  Each week, she downloads 4 new songs.  Write an expression to show the total number of songs on Iris's playlist after [tex]w[/tex] weeks.

This scenario can be modeled as an arithmetic sequence since Iris is adding a constant number of songs to her playlist each week.

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

We are told that she starts with 120 songs on her playlist, so [tex]a=120[/tex]

We are told that she adds 4 new songs each week, so [tex]d=4[/tex]

Also, [tex]n=w[/tex]

Substituting these values into the formula:

[tex]\implies a_w=120+(w-1)4[/tex]

[tex]\implies f(w)=116+4w[/tex]

Answer:

Step-by-step explanation:

First Multiply 12.8, 36, and 24 1/2 or 12.8 x 36 x 24.5 which equals 11289.6, and divide it by 2 which gives you 5644.8 inches of water.

Answer:

833/90 as a mixed number is 9 and 23/90.

Step-by-step explanation:

How many times does 90 go in to 833? 9 times.

Then take the remaining so you can’t really simplify the fraction so it stays 23/90.

So your final answer is 9 and 23/90.

Answer:

The slope should be -2

You should go down 2 and go over 1.

Slope Intercept Form: y= -2x+3

Step-by-step explanation:

First, you need to identify the slope: (meaning whether it is a postive or negative.)

In this case, You have a negative slope.

This means instead of rising you're decreasing down.

When you "run" or move horizontally you MUST move right even if it's a negative slope.

Now, you need to identify your Y-Intercept.

Your Y-Intercept should be (0,3)

Next, you have to find your slope:

In order to find your slope, you need to find where the line is crossing the coordinate.

Start at (-1,5) and go down and over to (0,3)

Your answer should be that you went down 2 and over 1.

The slope can't be 2 because if it were to be 2, then that would be a positive slope which isn't our occasion.

The slope is -2.

In Slope Intercept Form: y= -2x+3

Answer:

6 days

Step-by-step explanation:

If the first bricklayer can build a wall in 15 days, he can build 1/15 of a wall in one day.

If the second bricklayer can build a wall in 10 days, he can build 1/10 of a wall in one day.

Therefore, if they work together, in one day they will complete

1/15 + 1/10 = 1/6

of the wall.

Since they can complete 1/6 of the wall in one day, they can complete 6/6 or one wall in 6 days.

by making 65 cuts , you can have 66   sixteen inch boards

Answer:

5 ft

Step-by-step explanation:

The height will divide the base of the triangle in two parts of 3 ft, making two smaller right triangles.

Then, to find the height, we can use the Pythagoras' theorem in one of these triangles:

6^2 = 3^2 + height^2

36 = 9 - height^2

height^2 = 27

height = 5.19 ft

Rounding to the nearest foot, we have height = 5 ft

Answer:

5.20 ft (nearest hundredth)

Step-by-step explanation:

[tex]\textsf{Height of an equilateral triangle}=\dfrac12(\sqrt{3}x)\quad \textsf{(where}\:x\:\textsf{is the side length)}[/tex]

Given:

[tex]\begin{aligned}\implies \textsf{Height} & =\dfrac12(6\sqrt{3})\\ & =3\sqrt{3}\\ & =5.20\: \sf ft \: \textsf{(nearest hundredth)}\end{aligned}[/tex]

Answer:

23/12

Step-by-step explanation:

2 1/2 = 5/2(3/3) = 15/6

1 1/3 = 4/3(2/2) = 8/6

15/6 - 8/6 = 7/6

7/6(1/2) = 7/12

16/12 + 7/12 = 23/12

Answer:

From the photo above i interpreted the question and drew a triangle to make it easier to solve

Tan is used to solve the question as we were given opposite (as height of the cliff) and to find Adjacent ( the distance between the foot of the cliff to the boat)

Tan θ =Opp/Adj

Tan 22°=15/a

Cross Multiply

aTanθ=15°

Divide both sides by Tan 22

aTan22/Tan22 = 15/Tan 22

a = 15/Tan 22°

a = 37.13 m

Therefore the distance between the foot of the cliff to the boat is 37.13 metres

If no withdrawls were made, the total amount of money Yoko would have in her account in 8 years is $6,319.84.

When an account is compounded semiannually, it means both the amount deposited and the interest accrued increases in value twice yearly.

The formula that can be used to determine the value of the account in 8 years is:

FV = P (1 + r)^nm

$4000 x (1.029)^(2x8) = $6,319.84

Answer:

27 pies

Step-by-step explanation:

looking at the data we see that for every 26 pies sold, 13 (half) were chocoltae cream pies.

26 divided by 2 = 13

from this we can tell that if she were to sell 54 pies, half of sales would be chocolate, meaning 54 divided by 2

54/2 = 27 pies

Answer:

A transformation of (0,4), in order words, adding 4 to all your y-values.

Step-by-step explanation:

If you were to plot f(x) and g(x), you'd notice that all the y-values have been moved up by 4. To prove this to yourself, lets take the y-intercept.

Let x = 0, then g(0) = 2 and f(0) = -2, as you can see the y-value of the intersect has been shifted upwards by 4. Therefore, it can be said that f(x) has been shifted by (0,4), so f(x) +4 = g(x).
