Natalie Spent $59.54 on songs after 5 months at online music service.
Step-by-step explanation:
Given:
Total membership cost =$14.99
Number of songs purchased in each month = 9
Cost per song = $0.99
We need to find total amount she had spent after 5 months.
Solution:-
So First we will Number of songs purchased in 5 months.
1 month = 9 songs
So in 5 months = Songs purchased in 5 months.
By Using Unitary method we get;
Songs purchased in 5 months =
Now Also Given:
1 song = $0.99
45 songs = Cost for 45 songs.
Again by using Unitary method we get;
Cost for 45 songs =
No Total Amount Natalie spent after 5 months is equal to Total membership cost plus Cost of songs purchased in 5 months.
framing in equation form we get;
Total Amount Natalie spent =
Hence Natalie Spent $59.54 on songs after 5 months at online music service.
The expression representing Natalia’s total charge, in dollars, for a membership lasting m months is given by: Option B: 1.09(5.95m) + 15
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given that:
Monthly membership fee by online music service considered = $5.95Tax of 9% on monthly feeOne time initiation fee = $15Time for which she uses this service = m monthsTotal charge Natalia has to pay for m months = Monthly membership fees for m months + 9% tax on it per month + one time initiation fees.
Monthly membership fees + tax amount = $5.95 + 9% of $5.95
= [tex]5.95 + \dfrac{5.95}{100} \times 9 = 5.95 (1 + 0.09) = 5.95(1.09)[/tex] (in dollars)
This is paid for 'm' months, so:
Membership fees + tax amount (for m months) = [tex]5.95 \times (1.09)\times m[/tex] (in dollars)
And as One time initiation fee = $15, thus, we get:
Total charge Natalia has to pay for m months = [tex]5.95 \times (1.09)\times m + 15[/tex]
Equivalently, this is 1.09(5.95m) + 15 (in dollars) (as given by Option B)
(We don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Thus, the expression representing Natalia’s total charge, in dollars, for a membership lasting m months is given by: Option B: 1.09(5.95m) + 15

Answer:
m∠XYW = 32°, m∠WYZ= 85°
Step-by-step explanation:
6x+44-10x+65=117
-4x+109=117
-4x=117-109
=8
x=-8÷4
=-2
Hence, ∠XYW = (6x+44)°
= [6(-2)+44]°
= (-12+44)°
= 32°
Hence, ∠WYZ = 117° - 32°
= 85°
Callie got 37 pieces of Halloween candy. Her brother got 42 pieces. She wants to estimate to find about how many pieces of candy they have together. What should her first step be?
Answer:
Callie needs to hide both her and her brother's candy from him so that none is eaten/stolen. Then count each stash separately. Put the candies in groups of 10 to quickly establish that over 70 pieces were collected. Callie should steal a stack from her brother's pile while he's not looking. Just calmly shift one stack of ten candies to her side. She should announce she got 47 pieces and her brother only 32.

Answer:
8 from the box on right corner
A. Only A
B. Only B
C. Both
D. Neither
Answer:
A. Only A
Step-by-step explanation:
Lets take a look at Sequence A first. By translating triangle MNO along line segment NB, MNO's top left corner is now on point B, but the shape and orientation have not changed. Then, when we reflect MNO over the vertical line that goes through B, we "flip" MNO onto ABC exactly.
So Sequence A DOES map MNO onto ABC
Now let's take a look at Sequence B to see if it works too. First, we reflect, or "flip" triangle MNO over the vertical line that passes through points M and O. Now MNO and ABC have the same orientation or shape, but aren't in the same location. Next, Sequence B tells us to translate MNO along line segment MB. This puts point M on point B, resulting in the two triangles next to each other and in the same orientation, touching at point B, but not mapped onto one another.
So the answer is choice A: Only A maps MNO onto ABC
Can someone please help how I could find the square root for 121? Please explain step by step to get marked as brainliest!
Answer:
+ or - 11
Step-by-step explanation:
To find the square root of 121, think of a number that multiplied by itself would get to 121. This number is 11. However, do remember that the number could also be negative 11 bencause a negative times a negative becomes positive. I would advise you to try memorizing the squares of 0 to 15 to help you with this. Otherwise, you can just use a calculator.
Hope this helps! :)

1 Solve the system of equations by the substitution method. 5x+10y = 30 4x + 8y = 36 Select the correct choice below and fill in any answer boxes within your choice. A. The solution is (Simplify your answer. Type an ordered pair.) B. There are infinitely many solutions: {(x,y)|5x + 10y = 30} or {(x,y)|4x + 8y = 36}. C. There is no solution: Tor .
The system of equations:
5x + 10y = 30
4x + 8y = 36
Has no solutions, the correct option is C.
How to solve the system of equations?Here we have the system of equations:
5x + 10y = 30
4x + 8y = 36
We want to use the substitution method, then we need to isolate one of the variables. Let's work with the second equation:
4x + 8y = 36
Divide by 4:
x + 2y = 9
x = 9 - 2y
Now replace that in the other equation to get:
5*(9 - 2y) + 10y = 30
45 - 10y + 10y = 30
45 = 30
This is a false equation, thus, the system has no solutions.

a data survey representative calls phone numbers selected at tandom until someone answers. each call has a .22 probability of someone answering it. let N be the number of calls until someone answers.
What type of variable is N?
Binomial, geometric or neither?
Since the number of trials is not fixed, N is neither a binomial or a geometric variable, it is an inverse binomial variable.
The sample is chosen at random, hence, the trials are independent, that is, each person has the same probability of answering it, hence N is not a geometric variable.
For it to be a binomial distribution, there needs to be a fixed number of trials, which there is not, hence, N is also not a binomial variable.

Answer:
218
-72
12° C
Step-by-step explanation:
The magnitude of a single number is the positive version of that number.
We write it mathematically like this:
|−218|=218
|-12|=12
The magnitude of a number is also known as the absolute value, and literally means the 'size' of the number, not worrying if it is positive or negative.
For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.

Athlete J runs 2/3 of a mile in 8 minutes. Athlete H runs 2 3/4 miles in 1/2 hour.
1: If Athlete J continues at that speed, how long will it take to run one mile?
2: How long will it take Athlete J to run 5 miles at that same speed?
3: Who runs faster, J or H? Why?
The number of minutes it would take Athlete J to run one mile is 12 minutes.
The number of hours it would take Athlete h to run 5 miles is 10/11 hour.
Athlete h runs faster because his average speed is greater than that of Athlete J.
In order to determine the time it would take Athlete J to run one mile, the average speed has to be determined.
Average speed = total distance / time
2/3 ÷ 8
2/3 x 1/8 = 1/12 mile / minute
Time it would take Athlete J to run one mile = distance / speed
1 ÷ 1/12 = 12 minutes
Average speed of Athlete H = 2 3/4 ÷ 1/2
11/4 x 2 = 5 1/2 miles / hour
Time it would take Athlete H to run 5 miles = distance / speed
5 ÷ 11/2
5 x 2/11 = 10/11 hours
