A music sharing service has an initial fee of $25 and a monthly fee of $6. When a person joins the service, it costs the company $70 to create the new account. Which inequality can be used to determine how many months, m, it would take for the company to stop losing money on a new customer?
Answers
Answer: [tex]25+6m > 70[/tex]
Step-by-step explanation:
Let m = Number of months
Combined charges for music sharing service = 25+6m
Cost of joining to company = $70
According to the question,
Combined charges > Cost of joining to company (To find number of months it would take for this)
[tex]25+6m > 70[/tex] (required inequality)

An appliance store sells microwave ovens and has many different styles to choose from. A handout from the store
contains details about brand, type (countertop or over-range), number of power settings, and color. Which of the
variables is a discrete quantitative variable?
O brand
O type
power settings
O color
Answers
Answer:
Power settings.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are; continuous and discrete random variable.
A discrete random variable is a data set in which the number of possible values are either finite or countable. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
In this scenario, an appliance store sells microwave ovens and has many different styles to choose from. A handout from the store contains details about brand, type (countertop or over-range), number of power settings, and color.
Hence, the variable which is a discrete quantitative variable is the number of power settings because its values are countable or finite, usually it ranges from 100 to 800.

Answer:
A = 37°B = 63°C = 16°Step-by-step explanation:
The tangent function relates an angle to the measures of its adjacent and opposite sides. The inverse tangent (arctan) function can be used to find the angle from its tangent value.
Tan = Opposite/Adjacent
angle = arctan(opposite/adjacent)
A = arctan(3/4) ≈ 37°
B = arctan(2/1) ≈ 63°
C = arctan(2/7) ≈ 16°

The length of cell A is 8x10 to the power of negavtive 6 m. The length of cell B is0.0000004 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.
Answers
Answer:
Ratio of length of cell A to cell B is 20 : 1
Step-by-step explanation:
Length of cell A = [tex]8\times 10^{-6}[/tex] m
Length of cell B = 0.0000004 m
Convert the length of cell B into scientific notation.
Length of cell B = [tex]4.0\times 10^{-7}[/tex]
Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]
= [tex]2\times 10^{7-6}[/tex]
= 20
Therefore, ratio of length of cell A to cell B is 20 : 1

Using inverse function concepts, the correct option is:
B. Domain: x < -2 Range: y> 3
--------------------------
The domain of a function is the set that contains all possible input values.The range of a function is the set that contains all possible output values.In the inverse function, input and output are exchanged, thus, domain and range are also exchanged.For the original function, the domain is x > 3 and the range is y < -2.Thus, for the inverse function, the domain is x < -2 and the range is y > 3, which means that option B is correct.A similar problem is given at https://brainly.com/question/24603090

7x-130=110+9x. show with steps
Answers
Answer:
x=-120
Step-by-step explanation:
7x-130=110+9x
add 130 to both sides of the equation
7x-130+130=110+9x+130
Simplify
7x=9x+240
Subtract 9x from both sides
7x-9x=9x+240-9x
Simplify
-2x=240
divide both sides by -2
-2/-2=240/-2
simplify
x=-120
-7x -7x
-130=110+2x
-110 -110
-240=2x
