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?

Answers

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.

P(4 heads)= 1/20

Experimental Probability = 1/20 * 100 = 0.05 * 100 = 5%

Answers

Answer:

[tex]\frac{11}{20}[/tex]

Step-by-step explanation:

[tex]\frac{4}{5} - \frac{1}{4}[/tex]          Subtract the students who don't have protractors from the students who have mathematical instruments.

[tex]\frac{11}{20}[/tex]

9514 1404 393

Answer:

  3/5

Step-by-step explanation:

We assume that every student with mathematical instruments who hasn't lost their protractor will have a protractor.

If 1/4 of the students with instruments lost their protractor, then the remaining 3/4 of students with instruments still have their protractors. The fraction of the class with protractors is ...

  (3/4)(4/5) = 3/5

3/5 of the students in the class have protractors.

It’s only one question plz help (DON’T GUESS NO LINKS) please I will do anything there is a part two I’m struggling and this is the last assignment that will bring my grade up!!

Answers

Answer:

For question 1 it's B

For question 2 it's C

Step-by-step explanation:

For question 1, you have to apply the "Triangle Inequality Theorem"

A+B > C

B+C > A

A+C > B

Let's say that A=22, B=17, C= 14

22+17 > 14       True

17+14 > 22       True

22+14 > 17       True

Therefore, the answer is B

For question 2, you apply the rule of the sum of the triangles which is 180°

70+70+? = 180

140+? = 180

? = 40

Therefore, it's C

Spencer is riding his bicycle 2 7/10 miles to the park. He rides 1 1/4 miles and stops to take a drink. How much farther does Spencer have to ride to the park? Show your work.

Answers

Convert both mixed numbers to improper fractions since they do not have a similar denominator.

2 7/10 becomes 27/10
1 1/4 becomes 5/4

Now you need to find the least common denominator that 10 and 4 go into which is 20.

Multiply the top and bottom by the number it takes to make the denominator in each fraction 20

27/10 becomes 54/20 because you multiply the 10 and 27 by 2.

5/4 becomes 25/20 because you multiply the 4 and 5 by 5.

Now you can subtract the two fractions:

54/20 - 25/20 = 29/20

29/20 can be reduced to 1 9/10 which is how much farther he must go.

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

Answers

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

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
