Answer:
After 100 songs
Step-by-step explanation:
2.50x=1.50x+50
.50x=50
÷.50
X=100
Great Songs will be the better deal after 100 songs.
What are mathematical operations?Mathematical operations can also be defined by using built-in functions to subtract, divide, and multiply. The arithmetic operator is the one who conducts the arithmetic operation.
* Multiplication procedure: Values on both sides of the operator are multiplied.
For instance, 7×2 = 14
/ Division: Divides the left operand by the right operand
For instance, 4/2 = 2
MyTunes imposes a fee of $2.50 per song. Great Songs charges $1.50 for each song and includes a $50 one-time membership fee, as stated in the question.
Let the songs that come after Great Songs would be x, the better the deal.
⇒ 2.50x = 1.50x + 50
⇒ 0.50x = 50
Divided by 0.50 into both sides of the equation,
⇒ x = 100
Therefore, Great Songs will be the better deal after 100 songs.

If cos(x) = Negative one-fourth and tan(x) < 0, what is sin(2x) ? Negative StartFraction StartRoot 15 EndRoot Over 4 EndFraction Negative StartFraction StartRoot 15 EndRoot Over 8 EndFraction StartFraction StartRoot 15 EndRoot Over 8 EndFraction StartFraction StartRoot 15 EndRoot Over 4 EndFraction
The value of sin(2x) is [tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]
How to determine the value of sin(2x)The cosine ratio is given as:
[tex]\cos(x) = -\frac 14[/tex]
Calculate sine(x) using the following identity equation
[tex]\sin^2(x) + \cos^2(x) = 1[/tex]
So we have:
[tex]\sin^2(x) + (1/4)^2 = 1[/tex]
[tex]\sin^2(x) + 1/16= 1[/tex]
Subtract 1/16 from both sides
[tex]\sin^2(x) = 15/16[/tex]
Take the square root of both sides
[tex]\sin(x) = \pm \sqrt{15/16[/tex]
Given that
tan(x) < 0
It means that:
sin(x) < 0
So, we have:
[tex]\sin(x) = -\sqrt{15/16[/tex]
Simplify
[tex]\sin(x) = \sqrt{15}/4[/tex]
sin(2x) is then calculated as:
[tex]\sin(2x) = 2\sin(x)\cos(x)[/tex]
So, we have:
[tex]\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14[/tex]
This gives
[tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

Leslie's sister gave Leslie $120 as her celebration gift to get a job. Leslie put all the money into her bank account. Then she started save $100 each month. a. Write an equation in slope-intercept form (v = mx + b) to describe the relationship number of month and the total amount of savings.
Answer:
v = $100x + $120
Step-by-step explanation:
In this scenario, the fixed amount would be the $120 that Leslie's sister gave her. While $100 would be multiplied by the number of months (x) that have passed by which in this scenario would be our variable since we do not have this information. Lastly, these two values would be added to give us Leslie's total savings (v)
v = $100x + $120

Please help me out Solve for x and y
Answer:
\sqrt{81 + x^2} = y
\sqrt{y^2 - 7^2} = x
Step-by-step explanation:
They would be Pythagorean Triples.
a^2 + b^2 = c^2
9^2 + x^2 = y^2
\sqrt{81 + x^2} = y
7^2 + x^2 = y^2
x^2 = y^2 - 7^2

In the given figure
∵ BA // CF
∵ BC is a transversal
∵ ∠1 and ∠BCF are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠1 = m∠BCF
∴ ∠1 ≅ ∠BCF ⇒ (1)
∵ BC // ED
∵ CF is a transversal
∵ ∠BCF and ∠2 are corresponding angles
∵ The corresponding angles are equal in measures
∴ m∠BCF = m∠2

We will solve the given expressions and find the answer in decimals.
1). [tex]5\frac{6}{15}+(-2\frac{4}{5})[/tex] = [tex]5\frac{2}{5}-2\frac{4}{5}[/tex]
= 5.4 - 2.8

= -3.3 + 0.35
= -2.95
3). [tex]\frac{5}{-1.6}=-\frac{5}{1.6}[/tex]
= -3.125
4). (-4.5) × (-2.3) = 10.35

(4). Simplifying polynomials, help pls:) brainliest involved
Answer:
Explanation:
To simplify a polynomial, we have to do two things: 1) combine like terms, and 2) rearrange the terms so that they're written in descending order of exponent.
First, we combine like terms, which requires us to identify the terms that can be added or subtracted from each other. Like terms always have the same variable (with the same exponent) attached to them. For example, you can add 1 "x-squared" to 2 "x-squareds" and get 3 "x-squareds", but 1 "x-squared" plus an "x" can't be combined because they're not like terms.
Let's identify some like terms below.
f(x)=−4x+3x2−7+9x−12x2−5x4
Here you can see that -4x and 9x are like terms. When we combine (add) -4x and 9x, we get 5x. So let's write 5x instead:
f(x)=5x+3x2−7−12x2−5x4
Let's do the same thing with the x-squared terms:
f(x)=5x+3x2−7−12x2−5x4
f(x)=5x−9x2−7−5x4
Now there are no like terms left. Our last step is to organize the terms so that x is written in descending power:
f(x)=−5x4−9x2+5x−7

Suppose a publishing company estimates that its monthly cost is C ( x ) = 600x^2 + 300x C(x)=600x^2 +300x and its monthly revenue is R ( x ) = − 0.4 x 3 + 700x^2 − 60 0 x + 500 R(x)=−0.4x^3 +700x^2 −600x+500, where x is in thousands of books sold. The profit is the difference between the revenue and the cost. What is the profit function, P(x)?
Here is a riddle:
The sum of two numbers is less than 10.
If we subtract the second number from the first, the difference is greater than 3.
Write a system of inequalities that represents this situation. Let f represent the first number and s represent the second number.
Answer:
The system of inequalities that represents this situation will be:
[tex]f + s < 10[/tex]
[tex]f - s > 3[/tex]
Step-by-step explanation:
Let 'f' represent the first numberLet 's' represent the second number.Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.
so the inequality would be: f + s < 10Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.
so the inequality would be: f-s > 3Thus, the system of inequalities that represents this situation will be:
[tex]f + s < 10[/tex]
[tex]f - s > 3[/tex]
Rhianna has $100 in a savings account that earns 5% interest per year.The interest is not compounded.How much interest will she earn in 1year?Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$5
Step-by-step explanation:
Using the formula given i=prt we can do the following: 100 x 0.05 x 1= $5
Therefore the total interest after one year would be $5

Addisonand Nolan are reading the same book. At the beginning of the month, Addison was on page 7 and Nolan was on page 47. Addison will read 11 pages per day and Nolan will read 6 pages per day. Let A represent the page of the book that Addison is on at the end of t days into the month, and let N represent the page of the book that Nolan is on at the end of t days into the month. Write an equation for each situation, in terms of t, and determine whether Addison or Nolan is farther along in the book after 4 days.
Answer:
A = 51 pages
N = 71 pages
Nolan will be 20 pages farther along in the book than Addison after 4 days.
Step-by-step explanation:
for Addison if you multiply 11 by 4 you get 44 then you add 7 you get 51
For Nolan if you multiply 6 by 4 you get 24 then you add 47 and you final answer is 71
