IRA HAS 120 SONGS ON HER PLAYLIST .EACH WEEK SHE DOWNLOIADS FOR NEW SONGS
If she adds songs new in constant amount like 2 per week
Then it will form an arithmetic sequence.
Where common difference is dAnswer:
[tex]f(w)=116+4w[/tex]
Step-by-step explanation:
QuestionIris 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.
SolutionThis 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 termsWe 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]
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?
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

Length * Width10 * 550 cm²Together:
50 cm² + 14 cm²64 cm²Answer:
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
= 64 cm²

Answer:
B -- Recipe 2 (Gluten-Free)
Step-by-step explanation:
Recipe 1
5 / 16 = 0.3125
Recipe 2
3 / 8 = 0.375
Recipe 2 (Gluten-Free) has a higher ratio so it must have a stronger taste.
Answer:
Your answer would be:
B.) The gluten-free batch has the stronger butterscotch
Regular batch:
5 / 21
5 / 21 = 25 / 110
Gluten-free batch:
3 / 11
3 / 11 = 30 / 110
Solution:
30 / 110 > 25 / 110
In conclusion, the gluten-free batch has the stronger butterscotch.

find a number halfway between 2 1/2 and 1 1/3
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

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

Step-by-step explanation:
Given:
[tex]\text{Radius of circle: 2.5 cm}[/tex]
Formula:
[tex]\text{Circumference:} \ 2\pi r[/tex]
Substitute the radius in the circumference formula:

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!!!
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.
Nicole's Pie Shop recently sold 26 pies, of which 13 were chocolate cream pies. Considering this data, how many of the next 54 pies sold should you expect to be chocolate cream pies
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
833/90 as a mixed number
Answer:
