IRA HAS 120 SONGS ON HER PLAYLIST .EACH WEEK SHE DOWNLOIADS FOR NEW SONGS

Answers

She has initially 120songs

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

Then it will form an arithmetic sequence.

Where common difference is d

Answer:

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

Step-by-step explanation:

Question

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.

Solution

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:

[tex]a_n[/tex] is the nth terma is the first termd is the common difference between terms

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]

The first bricklayer can build a wall in 15 days, the second bricklayer can build the same wall in 10 days. How long will it take them to build the wall together?

Please help fast ASAP!!
Will mark brainiest!!!

Answers

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.

A surveyor standing on top of a cliff found that the angle of depression of a boat as sea is 22°. if the top of the cliff is 15m above sea level how far is the boat from the foot of the cliff?​

Answers

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

How much more does the student need to save to buy the laptop

Answers

Answer:

A

Step-by-step explanation:

Starting amount =                             307.50

1 month saving = 100

5 month saving = 5*100                   500.00

Total so far                                         807.50

Let the total amount be x

75% *x = 807.50

75/100 x = 807,59                              Multiply both sides by 100

75 x = 807.50 * 100                          

75 x = 80750                                      Divide by 75.

x = 80750 / 75

x = 1076.67

That is not the answer. That's the total cost of the laptop.

The amount needed is

Amount needed = Total Cost - what has been saved

Amount needed = ????

Total Cost = 1076.67

What has been saved = 807.50

Answer

Amount needed = 1076.67 - 807.50 = 269.17

Together:

50 cm² + 14 cm²64 cm²

Answer:

d.  64 cm²

Step-by-step explanation:

Separate the shape into two rectangles (see attached image).

Formula

Area of a rectangle = width × length

Rectangle 1

Area = 2 × 12

        = 24 cm²

Rectangle 2

Area = 5 × (10 - 2)

        = 5 × 8

        = 40 cm²

Total Area

Total area = Area of Rectangle 1 + Area of Rectangle 2

                  = 24 + 40
