You have a $50 gift card to the same site. You want to buy an album with 16 tracks for $12.99 and then use the rest of the gift card for single tracks. How many songs can you buy with the gift card?

Answers

first you will subtract 12.99 from 50
50 - 12.99 = 37.01
now you need to divide 16 by 12.99 to find out how much it costs for a single song
16 divided by 12.99 = $1.23
now you will divide 37.01 divided by 1.23
37.01 divided by 1.23 = about 30
this means youll get about 30 single tracks with your gift card.
let me know if you have any further questions
:)

Final answer:

After purchasing an album for $12.99 from the $50 gift card, the remaining balance is $37.01, which allows the purchase of 37 more single tracks, assuming each track costs $1.

Explanation:

To determine how many songs can be bought with a $50 gift card after purchasing an album for $12.99, we need to subtract the cost of the album from the total amount on the gift card. So, we have:

Total amount on gift card: $50Cost of album: $12.99

Subtracting the cost of the album from the gift card amount gives us:

$50 - $12.99 = $37.01

Assuming that each single track costs $1 as per the scenario provided, we can divide the remaining balance by the cost per single track:

$37.01 ÷ $1 per track = 37 tracks

This means that you can purchase 37 more single tracks with the remaining balance on the gift card.

Find the fuction h (x) =f(x) - g (x) if f (x)=3^x and g (x)= 3^2x - 3^x

Answers

if h(x) = f(x) - g(x)

then --> h(x) = 3^x - 3^2x - 3^x
h(x) = -3^2x

To find h(x) = f(x) - g(x), we substitute and simplify the given functions. The result is h(x) = 2 × 3ˣ - 3²ˣ. This solution involves basic algebraic manipulation and exponent rules.

Let's start by defining the given functions:

f(x) = 3ˣg(x) = 3²ˣ - 3ˣ

We need to find h(x) = f(x) - g(x). Substitute the expressions for f(x) and g(x):

h(x) = 3ˣ - (3²ˣ - 3ˣ)

Now simplify the expression inside the parentheses:

h(x) = 3ˣ - 3²ˣ + 3ˣ

Combine like terms:

h(x) = 3ˣ+ 3ˣ - 3²ˣh(x) = 2 × 3ˣ - 3²ˣ

Thus, the function h(x) = 2 × 3ˣ - 3²ˣ is found by subtracting g(x) from f(x).

Since there is one real root and one complex root, there must be one additional real root and another complex root that is the conjugate of the one given.

The conjugate complex roots give rise to the factor
.. (x -2 -5i)*(x -2 +5i)
.. = (x -2)^2 +25
.. = (x^2 -4x +29)

The given real root gives rise to the factor
.. (x +2)

The remaining factor can be written as
.. (ax -3)
since we know the product of the constant terms in these factors must be -174.

The product of these factors is
.. (x +2)(x^2 -4x +29)(ax -3)
.. = ax^4 -(2a +3)x^3 +(21a +6)x^2 +(58a -63)x -174

Matching x-coefficients, we have

You need the greatest common factor of the two numbers.

First, we find the prime factorization of each number.

72/2 = 36
36/2 = 18
18/2 = 9
9/3 = 3
3/3 = 1

72 = 2^3 * 3^2

90/2 = 45
45/3 = 15
15/3 = 5
5/5 = 1

90 = 2 * 3^2 * 5

To find the GCF, use only common factors with the lower exponent.

Both 72 and 90 have 2 as a factor. 72 has 2^3, and 90 has 2. 2 has a lower exponent than 2^3, so we use 2.

Both 72 and 90 have 3 as a factor. The both have 3^2, so we use 3^2.

90 has 5 as a factor, but 72 does not, so 5 is not a common factor, so we do not use 5.

The GCF is the product of the factor we use.

GCF = 2 * 3^2 = 2 * 9 = 18

The system of equations 4x-y=4(x+1) , y = 6 has:
A. one solution
B. infinitely many solutions
C. no solution

Answers

The system of equations 4x-y=4(x+1) and y=6 has no solution.

To determine the solution(s) of the system of equations, let's analyze each equation:

Equation 1: 4x - y = 4(x + 1)

Equation 2: y = 6

To simplify Equation 1, we can distribute 4 on the right side:

4x - y = 4x + 4

By rearranging terms, we have:

- y = 4

Comparing Equation 2 with this result, we see that the two equations are contradictory. Equation 2 states that y = 6, while the modified Equation 1 states that y = -4. This means there is no value of y that can simultaneously satisfy both equations.

Thus, the system of equations has no solution.

Therefore, the correct answer is C. no solution.

7b divided by 12=4.2 what is b

Answers

Final answer:

To solve for b in the equation 7b divided by 12 equals 4.2, multiply both sides by 12 and then divide by 7, resulting in b being equal to 7.2.

Explanation:

To solve the equation 7b ÷ 12 = 4.2 for b, we must isolate b on one side of the equation. We can begin by multiplying both sides of the equation by 12 to cancel out the division by 12 on the left side. This results in the equation 7b = 4.2 × 12. To find the value of b, we then divide both sides of the equation by 7:

Multiply both sides by 12: 7b ÷ 12 × 12 = 4.2 × 12Simplify: 7b = 50.4Divide both sides by 7: 7b ÷ 7 = 50.4 ÷ 7b = 7.2

Therefore, the value of b is 7.2.

Final answer:

To find the value of b in the equation 7b/12 = 4.2, multiply both sides by 12 and then divide by 7 to get b = 7.2. The value of b is 7.2.

Explanation:

The student is asking how to find the value of b in the equation 7b divided by 12 equals 4.2. To solve for b, you can follow these steps:

Write down the original equation: 7b / 12 = 4.2.Multiply both sides of the equation by 12 to eliminate the denominator: 12 * (7b / 12) = 12 * 4.2, which simplifies to 7b = 50.4.Divide both sides by 7 to solve for b: 7b / 7 = 50.4 / 7, which gives b = 7.2.

Therefore, the value of b is 7.2.

What is the solution set to the inequality-3x 5.92-15.4 for x in the set (-10,-5, 0, 5, 10)?

Answers

I have attached an image of the question

Answer:
-10 , -5 , 0 and 5

Explanation:
The given inequality is:
-3x + 5.9 ≥ -15.4

We will need to isolate the x on one side of the inequality as follows:
First, we will subtract 5.9 from both sides of the inequality as follows:
-3x + 5.9 - 5.9 ≥ -15.4 - 5.9
-3x ≥ -21.3

Then, we will divide both sides of the inequality by -3. Remember that when we divide by a negative number, we flip the inequality sign as follows:
-3x / -3 ≥ -21.3 / -3
x ≤ 7.4

This means that x could be any value starting from -∞ till 7.4
The given set is (-10,-5, 0, 5, 10)
Now, we will check the given options, the correct ones would be those having a value of 7.4 or less.
This means that the correct options are:
-10 , -5 , 0 and 5

Hope this helps :)

Final answer:

The solution set to the given inequality '-3x < 5.92 - 15.4' is {5, 10}.

Explanation:

The student's question seems to be about solving an inequality to find which values from a given set satisfy it. While the inequality itself appears to be incorrectly written or has a typo, I'll assume it's meant to be '-3x < 5.92 - 15.4'.

We can begin by simplifying the right side of the inequality:

5.92 - 15.4 = -9.48

So the inequality becomes:

-3x < -9.48

To solve for x, we divide both sides by -3, remembering to reverse the inequality sign because we are dividing by a negative number:

x > 9.48 / 3

x > 3.16

Now we can compare this result to the set of numbers given: (-10, -5, 0, 5, 10).

The only numbers greater than 3.16 are 5 and 10.

Therefore, the solution set to the inequality is {5, 10}.

Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a height of 10 meters and a circular base with a radius of 8 meters

Answers

I think it is 640 pi

Answer: Volume of an oblique cylinder is 2011.43 sq.m.

Step-by-step explanation:

Since we have given that

Radius of a cylinder = 8 meters

Height of a cylinder = 10 meters

Cavelieri's Principle states that volume of an oblique cylinder is same as the volume of right circular cylinder with equal radius and height.

As we know the formula for "Volume of cylinder":

[tex]Volume=\pi r^2h\\\\V=\frac{22}{7}\times 8\times 8\times10\\\\V=\frac{14080}{7}\\\\V=2011.43[/tex]

Answers

If Philip and his friends want to split the cost of gas evenly, how much should they each pay?
the amount of gas it consumes per 100 km = 6 l
the cost per litre = $1.50
the total distance of the trip = 4000 km
If 100 km consumes - 6 l
Then 1 km consumes - 6/100 l/km
therefore amount of gas for the whole trip of 4000 km = 6/100 l/km * 4000 km
the gas consumed = 240 l
cost of 1 l = $1.5
then the cost of gas for the whole ride = 240 l * $ 1.5
cost = $ 360
