Juan downloaded 30 songs from I-Tunes. The following is a table of Juan's songs that
show the types of songs and number of songs that he bought.
Answers
b) 9:30 = 3:10
c) for every 10 songs that Juan downloaded, 3 are hip hop
Answer:
a) 6:15 or 2:5 (simplified)
b) 9:30 or 3:10 (simplified)
c) For every 30 songs that Juan downloaded, 9 were hip-hop. OR For every 10 songs Juan downloaded, 3 were hip-hop.
Step-by-step explanation:
A ratio compares the relationship of different values in relation to each other.
For part a, we have to see the number of rap songs there are and the number of pop songs there are. According to the chart, there are 6 rap songs and 15 pop songs. Since the question asks for rap songs and then pop songs, the answer must be in this order. The answer would be 6:15. However, we know from multiplication and division that 3 is a multiple of both of these numbers. If both numbers are divided by 3, and therefore simplified, the answer would then be 2:5.For part b, we have to see the number of hip-hop songs there are and the number of total there are. Since the question asks for hip-hop songs and then total number of songs, the answer must be in this order. According to the chart, there are 9 hip-hop songs, but we cannot immediately find the total number of songs. To find this, we must add all of the songs together, which is 9 hip-hop+15 pop+6 rap=30 total songs. So, the answer is 9:30. 3 is a multiple of both of these values, so they can both be divided by 3 to get a simplified answer of 3:10.The sentence in the answer describes the ratio of 9:30 (or 3:10). It also describes the total number of songs compared to how many hip-hop songs Juan downloaded.**I added the non-simplified and simplified answers because I do not know what your teacher is looking for. You should use either of the answers depending on what your teacher asks you for.

The Acosta family went out to dinner. The price of the meal was $79.85. If the tip was 15%. How much money did the Acosta family pay for the meal, including tip?
A) $91.83
B) $67.87
C) $11.98
D) $94.85
Answers
Answer:
the Smith family pay for the meal = $ 36.39Step-by-step explanation:
The Smith family went out to dinner . The price of the meal was $ 29.85 .
The sales tax was 6 % of the price of the meal .
LEts find sales tax amount sales tax amount = price of meal *
sales tax 6 % ( 0.06 ) = 29.85 * 0.06 = 1.791 sales tax amount = 1.791
Price of the mean with sales tax = 29.85 + 1.791 = 31.641
The tip was 15 % of the meal and the sales tax now we find out tip amount for 31.641 15 % is 15 / 100 = 0.15
Tip amount = 31.641 * 0.15 = 4.74615
Now we add the top amount with 31.641 31.641+ 4.74615 = 36.38715
the Smith family pay for the meal = $ 36.39

Answer:
a) ∠XWY = 53°
b) ∠XZY = 106°
Step-by-step explanation:
The relationship between the central angle and the arc length is that they're equal. So, if arc XY = 106° this means that ∠XZY = 106°.
The relationship between the central angle ∠XZY and the inscribed angle ∠XWY is that the inscribed angle is half the value of the central one.
So, ∠XWY= ∠XZY/2 = 106/2 = 53
Results:
∠XWY = 53°
∠XZY = 106°

Jamal drives 3 times the hours that Danielle does. Jamal and Danielle drive for a total of 8 hours. How long did each person drive?
Answers
Answer: Danielle drive for 2 hours
Jamal drives for 2 × 3 = 6 hours
Step-by-step explanation:
Let the number of hours that Danielle used in driving to be represented by x.
Since Jamal drives 3 times the hours that Danielle does. This will be:
= 3 × x = 3x
Since Jamal and Danielle drive for a total of 8 hours. This can be formed into a equation as:
x + 3x = 8
4x = 8
x = 8/4
x = 2
Danielle drive for 2 hours
Jamal drives for 2 × 3 = 6 hours
Akira and Hideo are twins with different jobs. Akira earns five-eighths of what Hideo earns, but Akira’s expenses are half of Hideo’s. Akira ends up saving 40% of his income. What percentage of his income does Hideo save?
Answers
9514 1404 393
Answer:
25%
Step-by-step explanation:
Apparently, we're to assume that anything not spent is saved.
Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...
Akira's expenses = (3/5)(5/8) = 3/8 . . . . . of Hideo's income
Hideo's expenses are twice this amount, so ...
Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income
That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.
Hideo saves 25% of his income.

Answers

Answer:
g) $6000 ($528.18 to principal)
h) $9,471.82
i) $5471.82
Step-by-step explanation:
You can make a chart, as you have started. Such a chart is often referred to as an amortization schedule. The basic idea would be to show how each payment is distributed to interest and principal. The attached shows such a spreadsheet (with a few rows hidden). It is described in more detail below.
__
g) The total amount paid is 24 payments of $250 each, so $6000. These payments reduced his amount owed by $528.18. (We don't know if "toward his credit card" means "to the creditor" or "to pay his debt".)
__
h) The amount still owed is $9,471.82 (the ending balance after the 24th payment)
__
i) $5,471.82 went toward interest.
_____
Spreadsheet details
The first "Beg Bal" is the $10,000 owed. Each one after that is copied from the "New Bal" cell on the previous line.
Each "to interest" quantity is the product of the beginning balance and the monthly interest rate. The cell reference to the interest rate needs to be an absolute reference, so it remains the same when copying the formula to other cells.
The "to Principal" amount is the difference between the payment amount and the amount "to interest." The reference to the payment amount cell also must be an absolute reference.
The "End Bal" amount is the difference between the "Beg Bal" and the amount "to Principal".
As you can see, the payment math is not difficult. There is one multiplication (by the interest rate) and the rest is subtraction.
Note that the numbers in this spreadsheet are rounded by the display. In a real payment situation, the interest due amount would be rounded to the penny before being used in other calculations. The way we have done it will result in a few cents difference in the ending balance from the value if the interest were actually rounded at each step.
