A music download service charges a flat fee each month and $0.99 per download. The total cost for downloading 27 songs this month is $42.72. how much is the flat fee
Answer:
$15.99
Step-by-step explanation:
A music download service charges a flat fee each month and $0.99 per download.
Charge of downloaded 27 songs in this month = 0.99 × 27
= $26.73
The total cost for downloading 27 songs this month = $42.72
Therefore, the flat fee = 42.72 - 26.73 = $15.99
Flat fee for the month is $15.99.
Corinnes puppy eats 3 meals a day. How many meals does the puppy eat in 32 days
Corinne's puppy eats a total of 96 meals in 32 days.
To find out how many meals Corinne's puppy eats in 32 days, we need to multiply the number of meals per day by the number of days.
Determine the number of meals per day.
Since the puppy eats 3 meals a day, the number of meals per day is 3.
Calculate the total number of meals in 32 days.
Number of meals per day × Number of days = Total number of meals
3 meals/day × 32 days = Total number of meals
3 × 32 = Total number of meals
96 = Total number of meals
So, Corinne's puppy eats a total of 96 meals in 32 days.
Complete Question:
Corinnes puppy eats 3 meals a day. How many meals does the puppy eat in 32 days ?

Find the volume v of the described solid s. the base of s is the triangular region with vertices (0, 0), (5, 0), and (0, 5). cross-sections perpendicular to the y-axis are equilateral triangles.
Final answer:
To find the volume of the solid with a triangular base and equilateral triangular cross-sections, we integrate the area of the cross-sections along the y-axis from 0 to 5 based on the changing side length, which is a linear function of y.
Explanation:
The problem requires finding the volume of a solid with a triangular base and equilateral triangular cross-sections perpendicular to the y-axis. The base of the solid, S, is a right triangle with vertices at (0, 0), (5, 0), and (0, 5). The height of each equilateral triangular cross-section at any point y is the distance from the point (y, 0) to the hypotenuse of the triangular base, which is linear and can be described by the equation x + y = 5. Because cross-sections are equilateral triangles, each side of a cross-section is twice the length of the height. Therefore, the area of a cross-section is ½∙height²∙√3.
As we move along the y-axis from 0 to 5, the length of a side of each cross-section decreases linearly from 5 to 0. We can integrate the area of these cross-sections from y = 0 to y = 5 to find the total volume of the solid. The integral for the calculation of volume is:
∫ (2∙(5-y))² × √3/4 dy from y=0 to y=5
Upon integrating, this gives us the volume of the solid S.

4.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
4.4 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 40 as the denominator :
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
5.2 Adding up the two equivalent fractions

A store discounts the price of a beanbag chair by 20%. The price of the beanbag chair is marked as $16. What was the original price of the beanbag chair?
original price of the beanbag chair was $20 before the 20% discount was applied.
To find the original price of the beanbag chair that has been discounted by 20%, we set up an equation. Let's denote the original price as P. A 20% discount on the original price means the chair is being sold for 80% (100% - 20%) of P. This is represented by the equation 0.80P = $16.
To find P, we simply divide both sides of the equation by 0.80:
P = $16 / 0.80
This gives us:
P = $20
Therefore, the original price of the beanbag chair was $20 before the 20% discount was applied.

What is the range of arcsinx
Final answer:
The range of the inverse sine function, or arcsin(x), is the set of angles from -π/2 to π/2 radians, which is the same as -90° to 90° degrees. This defines the possible output values of the function for all real numbers in the interval [-1, 1].
Explanation:
The question "What is the range of arcsinx" concerns itself with the inverse trigonometric function, specifically the inverse of the sine function. The range of a function is the set of all possible output values it can produce. For the inverse sine function, or arcsin(x), the range is the set of angles that can produce all possible sine values, which are within the closed interval [-1, 1].
The sine function itself has a range from -1 to 1, so the arcsine function, being its inverse, takes on values that are angles that correspond to these sine values. In terms of angles, the range of the arcsin function is [-π/2, π/2] or [-90°, 90°] in degrees. This means that for any input value x within [-1, 1], the output of arcsin(x) will always be an angle measured in radians (or degrees) that falls within this range.

Write an equation and solve. 21 is 35% of what number?
If a grouping of numbers, variables, operators and/or functions used to represent a specific mathematical computation or connection is known as an expression. The expression 21 of 35% is 60.
What is the expression?Let x represent the unknown number
The given data states that 21 is 35% of that unknown number.
Mathematically we can express this relationship as an equation:
0.35 * x = 21
To solve for x divide both sides of the equation by 0.35:
x = 21 / 0.35
Evaluating the expression on the right side of the equation:
x = 60
Therefore, 21 is 35% of 60.

Find an equation of the line that satisfies the given conditions. x-intercept 1; y-intercept −4
The equation which is representing x-intercept 1; y-intercept −4 is y = 4x - 4.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the equation is y = mx + c which is the standard form of the linear equation.
Now,
At x- intercept ⇒ (1,0)
So,
0 = m(1) + c
c = -m
And y- intercept ⇒ (0,-4)
-4 = m(0) + c
c = -4
So m = 4
Therefore,
y = 4x - 4 will be the equation.
Hence "The equation which is representing x-intercept 1; y-intercept −4 is y = 4x - 4".
