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.
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.
HURRY PLEASE!! find the lcm of 3x^2-6x-24 and 9x^2-36
Answer:
yeeeeeeeeeeee
Step-by-step explanation:
Answer:
9(x - 2)(x - 4)(x + 2)
Step-by-step explanation:
3x^2 - 6x - 24
= 3(x^2 - 2x - 8)
= 3(x - 4)(x + 2)
9x^2 - 36
= 9(x^2 - 4)
= 9(x - 2)(x+ 2)
So the LCM is:
9(x - 2)(x - 4)(x + 2)

Norma and Albert both clean pools. Each charges a flat fee to clean a pool. Norma cleans 12 pools in 8 hours and earns $270. Albert cleans 9 pools in 7.5 hours and earns $195.75.
Answer:
Step-by-step explanation:
Noma cleans 12 pools in 8 hours
How many pools in how many minutes?
8 x 60= 480
He cleans 12 pools in 480 minutes
How many minutes does he take to clean a pool?
480/12 = 40
He cleans a pool in 40 minutes.
How much does he earn to clean a pool?
since he cleans 12 pools to earns $270
then 270/12 =22.5
Therefore, he charges $22.5 to clean a pool in 40 minutes.
Albert 9 pools in 7.5 hours
How many pools in how many minutes?
7.5 x 60= 450
He cleans 9 pools in 450 minutes
How many minutes does he take to clean a pool?
450/9 = 50
He cleans a pool in 50 minutes.
How much does he earn to clean a pool?
since he cleans 9 pools to earns $195.75
then 195.75/9 =21.75
Therefore, he charges $21.75 to clean a pool in 50 minutes.

The length of arc is 9.1506 cm.
What is Length of Arc?The length of an arc refers to the distance along the curve of a circle between two points on that curve. It is a measure of the portion of the circumference of a circle or any other curved shape.
The Formula for Length of Arc is θ/360 x 2πr.
We have,
Radius = 7.9 cm
Angle = 66.4 degree
Now, length of Arc
= θ/360 x 2πr
= 66.4 / 360 x 2 x 3.14 x 7.9
= 0.18444 x 2 x3.14 x 7.9
= 9.1506 cm
Thus, the length of arc is 9.1506 cm.

8 The perimeter P of a regular pentagon is 90 cm. What is the length x of each
side?
Answer:
18cm
Step-by-step explanation:
You would do 90/5 which is 18. Each side of the pentagon is 18cm.
Answer:
X = 18
Step-by-step explanation:
This is a regular pentagon, meaning that each side is the same. Now, since we know the perimeter, we can divide that by 5 to find each side's length (x). 90/5 = 18, so the length x of each side is 18.
If a square has a perimeter of 36 cm what is the area of the square
Answer:
The perimeter is just the sum of all four sides of the square.
36cm = Side 1 + Side 2 + Side 3 + side 4
Because it's a square, all the sides are the same length, so we can rewrite this as:
36cm = 4*Side
Side = 36cm/4 = 9cm
So to find the area, we multiply a length side, by a width side.
In this case (a square), we have:
Step-by-step explanation:
Answer:
area is 81
squares hav 4 sides which are all equal so divide 36 by 4 to get 9
to find area you do Length*Width so 9*9=81
