13. $25/month
14. 36 and 37
Step-by-step explanation:
Let a = monthly rate ($/month)
t = time (months)
k = installation cost
The equation for the cost of the internet service C is
C = at + k
Since C = $685. t = 24 months (2 years) and k = $85, we can solve for a:
at = C - k
or
a = (C - k)/t
= ($685 - $85)/(24 months)
= $25/month
14. Let n = the number
n + 1 = the number after n
Since the sum of two consecutive numbers is 73, we can write the equation as
n + (n + 1) = 73
which simplifies to
2n + 1 = 73
2n = 72
Solving for n, we find that
n = 36
so the other number is 36 + 1 = 37.
Answer For The First Question:
25
Here's why:
Note that the cost corresponds to 2 years of service. Also, the problem asks for the one-month fee. Then, a good start would be saying: OK, the cost of 24 months of service was $685, including the installation fee. Since this fee is a one-time cost, not a monthly cost, we need to subtract it from our total cost. Then the cost of the service minus the installation fee could be written as:
24x = 685 - 85
That is 24 months of service, at x cost per month, is equal to 685 minus 85.
If you solve this equation, you will find the value of x:
24x = 600
x = 600 ÷ 24
x = 25
The monthly fee is $25. In 2 years you paid 24 times 25, or $600. Add to this amount the installation fee of $85 and you will arrive at your total cost, which includes the installation fee.
Second Answer:
36 and 37
Here's why:
36+37=73
You can solve this by first dividing 73 by 2.
73/2 = 36.5
Next, take .5 away from one of the 36.5 and give it to the other one. That gives us an answer of 36 and 37.

What is the volume of a cone that has a height of 10 feet and a base with a surface area(B) of 9 square feet?
Answers
Answer:
30 cubic feet
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Height of cone (h) = 10 feet
Base surface area = π[tex]r^{2}[/tex] = 9 sq. feet
So we can calculate the volume of cone by using following formula,
volume of cone = (1/3)π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
Volume of cone = (1/3) 9 × 10
= 3 × 10
= 30 cubic feet

The length x using Pythagoras theorem is 15 unit.
What is Pythagoras theorem?According to the Pythagorean theorem, the square of the hypotenuse of a right triangle equals the sum of the squares of the other two sides.
Given:
Hypotenuse = 18 unit
Perpendicular = 10 unit
using Pythagoras theorem
H² = P² + B²
18² = 10² + B²
324 = 100 + B²
324 - 100 = B²
B² = 224
B= 14.966 unit
B= 15 unit
Thus, the measure for x is 15 unit.

Which represents the explicit formula for the arithmetic sequence on = 7 - 3(n - 1) in function form?
f(n) = 3n - 6
B f(n) = -3n - 6
f(n) = 3n - 10
D f(n) = -3n + 10
Answers
Answer:
Step-by-step explanation:
All this question is asking you to do is distribute through the parenthesis to simplify. Doing that gives us
f(n) = 7 - 3n + 3 and
f(n) = 10 - 3n or
f(n) = -3n + 10, choice D.
The representation of the function of the given arithmetic sequence 7 - 3(n - 1) is f(n) = -3n + 10 thus option (D) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
The machine may only produce one output for each input and will only accept inputs that are specifically listed as part of the function's domain.
As per the given,
a_n = 7 - 3(n - 1)
f(n) = 7 - 3n + 3
f(n) = -3n + 10
Hence "The representation of the function of the given arithmetic sequence 7 - 3(n - 1) is f(n) = -3n + 10".

What is the average rate of change for this exponential function for the interval from x = 7 to x = 8?
Answers
Answer:
4374
Step-by-step explanation:
Since, we are given table for x and y values
and table for average rate of changes
we can see the pattern of average rate of change
average rate of change for 5 to 6 is three times average rate of change for 4 to 5
but we have to find
average rate of change for 7 to 8
so, using same pattern
average rate of change for 6 to 7 is three times average rate of change for 5 to 6
average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)
so, we can plug value
average rate of change for 7 to 8 is 3*3*486
average rate of change for 7 to 8 is 4374

) Would you rather receive $1,500 a year for 12 years, or $1,200 a year for 20 years if the interest rate is 7%?
Answers
Answer:
$1200 should receive.
Step-by-step explanation:
To check whether to receive $1500 or $1200 just find the present values of each amount.
Present value of annuity $1500:
Present value of annuity = Annuity (P/A, 7%, 12)
Present value of annuity = 1500 (P/A, 7%, 12)
Present value of annuity = 1500 (7.9426)
Present value of annuity = $11913.9
Present value of annuity $1200:
Present value of annuity = Annuity (P/A, 7%, 20)
Present value of annuity = 1500 (P/A, 7%, 20)
Present value of annuity = 1500 (10.5940)
Present value of annuity = $15891
Thus, $1200 should receive.
