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?
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)

Here goes another question
Answer:
y = x - 8
Step-by-step explanation:
In order to solve this, we need to use point-slope form.:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - (-8) = 1(x - 0)
y + 8 = x
y = x - 8
Convert 132 pounds to kilograms. Use 1 kg = 2.2 lb.

Step-by-step explanation:
5x + 2 = 50 - x (vertically opp angle)
5x + x = 50 - 2
6x = 48
x = 8
if you wanna check it,
5x + 2 = 50 - x
5(8) + 2 = 50 - 8
40 + 2 = 42
42 = 42

The domain of a function h(x) is x > 3, and the range is y2 -2. What are the domain and range of its inverse function, h-1(x)?
A. Domain: x>3 Range: y2 -2
B. Domain: x2 -2 Range: y> 3
C. Domain: x>-2 Range: y> 3
D. Domain: x2 3 Range: y> -2
Answer:
I think it's b I don't know for sure though
Step-by-step explanation:
I don't know for sure tho
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

The 7th grade class experienced a 15% decrease in enrollment.Last year,the 7th grade class had 280 students. How many how many students are enrolled in the 7th grade this year?
Answer: 238
Step-by-step explanation: 10% of 280 is 28. 1% of 280 is 2.8. Multiply 2.8 times 5 and you get 14. Add 10% and 5% (28+14) and you get 15% which is 42. Subtract 42 from 280 and you get 238.
Answer:
232 students are enrolled this year.
Step-by-step explanation:
Since 15% of the enrollment of the previous year is gone, you must take 15% of the total number of students and subtract that from the total number of students.
[tex]280*0.15=42[/tex]
This tells us that the 15% decrease means there are 42 fewer students enrolled this year. Now you would just subtract 42 from 280.
280 - 42 = 232

Find the 7th term of the arithmetic sequence given a12=29 and
a16=53
a7=___
Answer:
Thus: a7=-1
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
We know: a12=29, a16=53, thus
[tex]a_1+(12-1)r=29[/tex]
[tex]a_1+(16-1)r=53[/tex]
Simplifying:
[tex]a_1+11r=29[/tex]
[tex]a_1+15r=53[/tex]
Subtracting both equations:
[tex]4r=53-29=24[/tex]
Solving:
[tex]r=24/4[/tex]
r=6
The 7th term can be found as 5 terms before the 12nd:
[tex]a_7=a_{12}-5r[/tex]
[tex]a_7=29-5*6=29-30=-1[/tex]
Thus: a7=-1

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°

If Ryan gives 4/9 of his 36 cards to Josiah, how many cards does he give Josiah?
Answer:
16 cards
Step-by-step explanation:
Answer:
Ryan gave 16 cards to Josiah.
Step-by-step explanation:
First we will divide 36 by 9.
36/9 = 4
We know that 1/9 of 36 is 4.
1/9 + 1/9 + 1/9 + 1/9 = ?
4 + 4 + 4+ 4 = ?
4 * 4 = 16
4/9= 16
Ryan gave 16 cards to Josiah.
Write 0.00000029 in scientific notation.
[tex]29 \times {10}^{ - 8} = 2.9 \times {10}^{ - 7} [/tex]
And we're done.
Thanks for watching buddy good luck.
