3. A website allows users to download individual songs or whole albums.
All songs cost the same price to download. All albums cost the same price
to download, Karim pays $30 to download 5 songs and 2 albums.
Kimberlyn pays $26 for download 3 songs and 2 albums. What is the cost
to download 1 song? 1 album?
Answer:
Each song costs $2 and each album costs $10.
Step-by-step explanation:
Since a website allows users to download individual songs or whole albums, and all songs cost the same price to download and all albums cost the same price to download, and Karim pays $ 30 to download 5 songs and 2 albums while Kimberlyn pays $ 26 for download 3 songs and 2 albums, to determine what is the cost to download 1 song and the cost to download 1 album, the following calculations must be made:
5X + 2Y = 30
3X + 2Y = 26
(30 - 26) / (5 - 3) = X
4/2 = X
2 = X
Therefore, each song has a cost of $ 2.
Thus, to know the cost of each album (knowing that both downloaded the same amount, that is, 2), the following calculation must be performed:
5x2 + 2Y = 30
10 + 2Y = 30
2Y = 30 - 10
2Y = 20
Y = 20/2
Y = 10
Therefore, each album has a cost of $ 10.

7 and - 1 1/2 on the number line?
Answer:
7 will lie on 0 and 1 and 1/2
Anyone know this......
The general equation is given as,
Un+1 = (Un)^3+2
here, n = number of the sequential entries like 0,1,2,3... so on.
so we get here as,
Uo = -3 , so we find U1 and U2
U1 = n+1 = 0+1
so,
===> U1 = (-3)^3 +2
===> U1 = -27 + 2 ==> U1 = -25
now, U2
U2 = n+1 = 1+1
so,
U2 = (-25)^3 + 2
U2 = -15625 + 2 ===> U2 = -15623
hence,
U1 = -25 and U2 = -15623

Answer:
If the secant = 2, this would be where the cosine = 1/2 = a 60° degree angle in the first quadrant and the 4th quadrant.
And the cot (60°) = 1/√3 = √3 /3
And the cot of a 60° angle in the 4th quadrant (i.e., 330°) is (- √3 /3)
The expression for the nth term in a sequence is 6n-3. Write the first 4 terms.
Answer:
3, 9, 15, 21
Step-by-step explanation:
6n-3
n = 1: 6(1) - 3 = 3
n = 2: 6(2) - 3 = 9
n = 3: 6(3) - 3 = 15
n = 4: 6(4) - 3 = 21
Jackie bought a CD for $11.50. The sales tax is 6%. How
much did Jackie pay for the CD, including the sales tax?
$12.19
before the tax price is $11.50
and %6 is equal to $0.69
therefore if you add those together you'll get an answer of $12.19

Choose the theorem that proves these triangles are congruent.
Answer:
ASA
Step-by-step explanation:
If STV is congruent to UVT as UTV is congruent to SVT, then TV is a transversal which is congruent to itself. Therefore, reading left to right, the theorem that proves the triangles congruent is ASA because we have two pairs of congruent angles and one side.

Answer:
It's the third option, y = [tex]\frac{1}{3}[/tex] x + 2
Step-by-step explanation:
It is rise over run.
This means you go up one, then go three right.
Answer:
Read below please :)
Step-by-step explanation:
when writing an equation, you use rise over run, or, [tex]\frac{rise}{run} or ( \frac{y}{x} )[/tex], so you'd get 3/1 (3) + 6/2 (3) as you can see, y = half of x. So, because you know what x(6), and what y(3) is, just imput the answers and see which makes sense.
Hope this helps :)

Simplify the following expression. 3^2/5 x 3^(-7/5) A. 1/243 B. -14/25 C. 1/3 D. -3
Answer:
C
Step-by-step explanation:
3^2/5 x 3^-7/5
We know that a^b* a^c = a^(b+c)
3^(2/5 -7/5)
3^ (-5/5) = 3^ -1
We know that a^-b = 1/ a^b
3^-1 = 1 / 3

A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 6m and a diameter of 6m. The container will be made from steel (including its top and bottom). If the steel costs $27 for each square meter, how much will the steel cost in total? If necessary, refer to the list of geometry formulas. For your calculations, do not round any intermediate steps, and use the π button on the ALEKS calculator. Round your answer to the nearest cent
Answer:
The cost of required steel is [tex]169.56 *27 = 4578.12[/tex] dollars
Step-by-step explanation:
The surface area of cylinder will be equivalent to the area of the steel sheet.
Surface area of cylinder [tex]= 2\pi rh+2\pi r^2[/tex]
Substituting the given values we get
Surface area of cylinder
[tex]= 2*3.14*3*6 + 2*3.14 *3^2\\= 169.56[/tex]square meter
Cost of 1 square meter of steel is $27
Then, the cost of required steel is
[tex]169.56 *27 = 4578.12[/tex] dollars
