Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21

help me fill in the blanks pleasee
Answers and Step-by-step explanations:
Let's look at the first row:
cost = _______ + _______ * (monthly payment)
The first blank should be the "down payment" because this is the initial, constant value that is paid. The second blank should be the "number of months" because this way, when multiplied by the actual amount each payment is (monthly payment), then we get the total amount paid during those months.
So, we have:
cost = (down payment) + (number of months) * (monthly payment)
Now for the second row, we just plug in numbers and variables:
335 = 50 + 6 * p
Finally, we can solve for p:
335 = 50 + 6p
6p = 285
p = $47.50
Answer:
Cost = down payment + no. of monthly payments × monthly payment
335 = 50 + 6 × p
285 = 6p
p = 47.5

Find the 14th term of the geometric sequence 1 , − 5 , 25 , . . .
Answer:
-1220703125
Explanation:
The 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
The sequence is:
1 , − 5 , 25 , . . .
The above sequence represents a geometric sequence.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity,
approaching either infinity or -infinity.
The common ratio = -5/1 = -5
The nth term a(n) = arⁿ⁻¹
The first term a = 1
The nth term a(n) = (5)ⁿ⁻¹
Plug n = 14
The 14th term a(14) = (-5)¹⁵⁻¹
The 14th term a(14) = (5)¹⁴
Thus, the 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.

The area of Miguel’s rectangular garden is 450 square feet. The garden is 9 feet wide.
How many feet of fencing will Miguel need to buy to enclose the garden on all four sides?
Answer: 118 feet
Step-by-step explanation:
For a rectangular shape: Area = W × L
450 = 9 × L
450 ÷ 9
L = 50
Perimeter of a rectangular shape = 2L + 2W
Perimeter = (2 × 50) + (2 × 9)
= 100 + 18 = 118 feet

There are only about 400,000 African elephants left in the world today. They are
classified as endangered by the International Union for Conservation of Nature, and
the population continues to decrease by 9% per year. What will the population of
African elephants be in fifty years?
Answer:
In 50 years there'll be approximately 3582 elephants.
Step-by-step explanation:
If they are decreasing at a rate of 9% per year, it means it's population by year is:
population(0) = 400000
population(1) = population(0)*(100% - 9%) = population(0)*(91%)
population(2) = population(1)*(91%) = population(0)*(91%)*(91%) = population(0)*(91%)²
population(3) = population(2)*(91%) = population(0)*(91%)²*(91%) = population(0)*(91%)³
And so on, so the number of population as years passes is:
population(n) = population(0)*(91/100)^n
In this case we want to know the population of elephants when n = 50, so we have:
population(50) = 400000*(0.91)^50 = 3582.033
In 50 years there'll be approximately 3582 elephants.

Write a problem that could be modeled with y=200(0.9).
First, I need to decide what equation this is like.
I believe this is y=mx.
We know that x is typically the input, and m is the constant function.
Y is the output.
So the original function may have been y=200x.
The only difference is now we've been given something to apply to the equation, in place of x.
2. Imagine a cloning machine. Whatever you put in, you get a copy of, and the original thing you put in. Its function would be y=2x. Let's pretend we decided to put three things in; 3 would go where x is.
Y would be the result of 3 copies and their originals, or 2(3).
(6=2(3))
Now, when someone else decides to use the cloning machine, they may put any number in, but the only properties that will change are y and x, not m.
The function will remain y = 2x. Any number could go in place of x, and multiplying x by 2 will give you the y. As long as you have a different value for x, the y will never be the same.
3. So now we have an understanding of what it means, we see that we have been given an x value to insert; an input.
A more practical example could be someting with money. This won't be entirely realistic, because we are dealing with a fraction of a number and another large number.
4. I decided to go with flour. I wanted the 200 to represent pennies, or cents. Before I landed on this, I looked up the cost of flour per pound. I found that the average is .43 dollars, which isn't terribly close to two dollars. But maybe the flour is high quality, so we can stick with that.
5. Seeing that this equation, y=200x, means we are charging 200 cents, or two dollars, we can write a problem from here.
Sylvia is in charge of selling home-harvested flour from an organic farm. She charges two dollars per pound of flower. Today, her next-door neighbors hope to buy a ninth of pound of flour, and they insist on paying with pennies. How many pennies do they need to pay for their order?

does anyone understand the Pythagorean Theorem
Answer:
a^2 + b^2 = c^2
Step-by-step explanation:
In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
a^2 + b^2 = c^2
a = side of right triangle
b = side of right triangle
c = hypotenuse

The rule T5, -0.5 oR 0, 180(x,y) is applied to triangle FGH to produce triangle F’G’H’. What are the coordinates of vertex F’ of triangle F’G’H’?
Answer:
Step-by-step explanation:
Rule for the transformations has been given as,
[tex]T_{(5, -0.05)o\text{R}(0, 180)}(x,y)[/tex] defines the rules as the translation by 5 units right and 0.5 units down followed by rotation of the triangle by 180° about the origin.
In other words,
Rule for translation:
F(x, y) → F"(x + 5, y - 0.5)
Followed by the rotation of 180° about the origin,
Rule of rotation,
F"(x', y') → F'(-x, -y)
Following these rules coordinates of the new triangle F'G'H' can be obtained.

Find the 66th term in the following
arithmetic sequence :
--92, -85, -78, -71, ...
Answer:
363
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 92 and d = - 85 - (- 92) = - 85 + 92 = 7 , thus
[tex]a_{66}[/tex] = - 92 + (65 × 7) = - 92 + 455 = 363
Answer:
363.
Step-by-step explanation:
We see that each term increases by 7.
This is an arithmetic sequence with first term (a1) = -92 and the common difference (d) is 7.
an = a1 + (n - 1)d
a66 = -92 + (66 - 1)7
= -92 + 455
= 363.
