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.
find the inverse of f(x) = 2x + 3
f−1(x)=x−32
Explanation:Follow the steps:
f(x)=2x+3
1- replace f(x) with y →y=2x+3
2- simply switch x and so the equation looks like x=2y+3
3- use algebra to solve for y. (isolate y)
x=2y+3
x−3=2y
x−32=y
This is the inverse function and is written as
f−1(x)=x−32

Cheryl is moving to a new house. Her old house is 3 kilometers and 457meters from her new house. How many meters is her old house from her new house.
Answer:
Her old house is 3000m+457m = 3457m from her new house.
Step-by-step explanation:
Conversion of units problems can always be modeled as a rule of three problem.
Rule of three problem:
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.
In the case of a conversion of units problem, the measures are:
- the value in one unit
- the value in another unit
As the value of the first unit increases, so will the value of the second unit. It means that in a conversion of units problem, we will always have a direct rule of three.
The problem states that Cheryl's new house is 3 kilometers and 457meters from her old house. The problem wants to know this distance purely in meters, so we have to convert 3km to meters. 1km = 1000m, so:
1km - 1000m
3km - xm
x = 1000*3
x = 3000m
Her old house is 3000m+457m = 3457m from her new house.

Each time Gertrude gets paid, 10% of her pay check goes to taxes. Last week, $ 40 was taken out of her check for taxes. What was the amount of Gertrude's pay check last week?
Gertrude's paycheck last week was $400.
Explanation:To find the amount of Gertrude's paycheck last week, we can set up an equation using the information given. Let's assume her paycheck amount is represented by 'x'. According to the problem, 10% of her paycheck, or 0.10x, is taken out for taxes. This amount is given as $40. So we can write the equation as 0.10x = 40. To solve for x, we divide both sides of the equation by 0.10: x = 40 / 0.10 = $400.

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".

The temperature of dry ice is -109.3°F, which is 183.6°F less than the outside temperature. What is the outside temperature?
To find the outside temperature, add the difference of 183.6°F to the dry ice temperature of -109.3°F, yielding an outside temperature of 74.3°F.
Explanation:The student is asking to find the outside temperature given that dry ice temperature is -109.3°F and that the outside temperature is 183.6°F higher than the dry ice. We can solve this by adding the temperature difference to the dry ice temperature.
Let's denote the outside temperature as T.
T = (-109.3°F) + 183.6°F
Now, let's perform the addition:
T = 74.3°F
Therefore, the outside temperature is 74.3°F.
Final answer:
The outside temperature can be calculated by subtracting 183.6°F from the temperature of dry ice (-109.3°F).
Explanation:
The outside temperature can be calculated by adding the temperature difference to the temperature of dry ice. The temperature difference is given as 183.6°F less than the outside temperature, which means we need to subtract 183.6°F from the temperature of dry ice (-109.3°F). So, the outside temperature would be -109.3°F + (-183.6°F) = -293.9°F.
You have 120 pieces of fabric to make a blanket. Each piece of fabric is a square with a side length of 6 inches. You use as many squares as possible to make a square blanket. What is the area of the blanket? How many pieces are left over? How many more pieces of fabric would you need to increase the size of the blanket?
A. Since the blanket to be made is a square, therefore there should be equal number of fabric on all sides. So find the square root of 120.
number of fabrics = sqrt (120) = 10.95
Since number of fabrics cannot be decimal, therefore the largest number of pieces of fabric per side is 10 (length and width).
Since each fabric measures 6 inches, so total length per side is 60 inches. The area is therefore:
Area of blanket = 60 in * 60 in = 3600 square inches
B. Since the two sides, length and width, has same number of fabrics which is 10, so total number used is = 10 * 10 = 100
So the left-over are 120 – 100 = 20 fabrics left over
C. To create a bigger blanket, it would require 11 fabrics per side, so total number used would be = 11 * 11 = 121
Therefore only 1 additional piece of fabric is required.

round 101 to the nearest ten
101 rounded to the nearest ten is 100.
What is Rounding Off?Rounding off of a number is defined as the simplification of the number by keeping the value of the number same but is made closer to the next number.
Rounding can be done for whole numbers as well as decimals.
Here the given number is 101.
101 is between 100 and 110. We can round it to either of these two.
We have to round it to the nearest ten.
The number in the tens place is 0.
Look at the number next to tens place, which is at ones place.
The digit at ones place is 1, which is less than 5.
So keep the number in tens place as such and add 0 to ones place.
So the number is 100.
Hence 101 when rounded to nearest ten is 100.
