Answer:
5n=c
Step-by-step explanation:
the equation 5n=c can represent the total cost Hong would have paid for the notebooks because given that each notebook costs $5, you would multiply 5 by the number of notebooks (n) that Hong would be purchasing, which would bring you to the cost (c) of the notebooks all together

Answer:
n = -1.25
Step-by-step explanation:
S(ABCD) = AB × AD
S(ABCD) = 2n × (4n + 5)
S(ABCD) = CD × AD
2n × (4n + 5) = CD × (4n + 5)
n = -1.25

Write down the smallest positive integer, n, such that 294n is a perfect square.
Step-by-step explanation:
Closest square root to 294 is 17(289) + 5
294 --> 9 is 287.
289 - 287 = 2.
2 is the biggest positive integer

X-4/4=8 Solve this variable on this equation
Answer:
x=9
Step-by-step explanation:
divide 4 by 4 to get 1
x-1=8
9-1=8
Hey there!
x - 4/4 = 8
x - 1 = 8
ADD 1 to BOTH SIDES
x - 1 + 1 = 8 + 1
CANCEL out: -1 + 1 because it give you 0
KEEP: 8 + 1 because it give you the x-value
NEW EQUATION: x = 8 + 1
SIMPLIFY IT!
x = 9
Therefore, your answer is: x = 9

What is the difference between a metric and a norm?
Answer:
A norm and a metric are two different things. .
Step-by-step explanation:
The norm is measuring the size of something, and the metric is measuring the distance between two things. A metric can be defined on any set . It is simply a function which assigns a distance (i.e. a non-negative real number) to any two elements .
The major difference between the matric and norms is that metric is a unit of measurement that measures the distance between two objects. The size of a single thing is measured by a norm.
What is measurement?It is defined as the numerical quantity that gives an idea about an object's size, length, width, and many more. It can be used to compare two objects.
The major difference between metrics and norms is as follows:
A metric is a unit of measurement that measures the distance between two objects. The size of a single thing is measured by a norm.Metrics may be expressed on almost anything, however, a norm can only be defined on vector spaces but since the definition of a norm requires that the things measured by the norm be added and scaled.Thus, the major difference between the matric and norms is that metric is a unit of measurement that measures the distance between two objects. The size of a single thing is measured by a norm.

Answer:
A: geometric; 4 times
B: arithmetic: 4 more
Step-by-step explanation:
An arithmetic model is a linear model, where the rate of change is constant. Growth or decay is by a constant amount from one interval to the next.
A geometric model is an exponential model, in which the rate of change is proportional to the amount. Growth or decay is by a constant factor from one interval to the next.
__
A)The equation for the sequence is given in "explicit" form:
[tex]A_n=2^{2n}[/tex]
The exponent can be split so this can be rewritten as ...
[tex]A_n=(2^2)^n=4^n[/tex]
If this were written in recursive form, it would look like ...
[tex]A_0=1,\ A_n=4\times A_{n-1}[/tex]
The fact that terms are related by a constant factor tells you the model is geometric. The factor tells you each hour the population is 4 times what it was in the previous hour.
__
B)The given equation is in "recursive" form. It tells you each term is 4 more than the previous one. This constant difference between terms means the model is arithmetic.
_____
Additional comment
In general, words like "more" or "increase" refer to addition, and the words "times" or "factor" refer to multiplication.

Michele's credit card had a balance of $579. 53 on August 1. On August 8, she made a payment of $500. On August 16, she made a charge of $200. On August 24, she made another charge of $350. What was her average daily balance?
By taking the average of her balance of each day of August, we will see that the average daily balance is $373.08
What was her average daily balance?
We know that:
On August 1, her balance was $579.53On August 8, her balance was $579.53 - $500 = $79.53On August 16, her balance was $79.53 + $200 = $279.53On August 24, her balance was $279.53 + $300 = $579.53So, first, her balance is $579.53 for 7 days. Then her balance is $79.53 for 8 days, then her balance was $279.53 for another 8 days, and finally, her balance was $579.53 for the last 8 days of august.
Then over the 31 days of August, the average daily balance will be:
[tex]A = \frac{7*579.53 + 8*79.53 + 8*279.53 + 8*579.53}{31} = 373.08[/tex]
So in August, her average daily balance was $373.08

Answer:
9x - 13y
Step-by-step explanation:
2(3x - 2y) + 3(x - 3y)
Use distributive law a(b + c) = ab + ac
⇒ 2·3x - 2·2y + 3·x - 3·3y
⇒ 6x - 4y + 3x - 9y
Gather like terms:

based on the statement is true?
Answer:
the right answer is F (exterior angle of triangle is equal to its sum of opposite interior angle of a traingle)
Answer: W = 40 degrees.
Step-by-step explanation: When you're finding a missing interior angle, all you need is the angle measurements of the other two angles. According to the picture, we have two 70's given, which both add up to 140. All the interior angles of a triangle need to add up to 180, and we have 140 so far. That's where the missing angle comes in. When you subtract 140 from 180, you get 40, which is your missing angle.

Answer:
A ≈ 8.6 ft²
Step-by-step explanation:
the area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] × 7 × 3 × sin55°
= [tex]\frac{1}{2}[/tex] × 21 × sin55°
= 10.5 × sin55°

A movie director needs to purchase 325 films. The film has a volume of 965 in', and the density of each film is 7.6 g/in?. Each film can be purchased for $0.34 per kilogram. What is the cost of the films?
The volume of the films is the amount of film in the case
The cost of the films is $810.41
How to determine the cost of the films?The given paramerers are:
Volume = 965 cubic inchesDensity = 7.6 gram per cubic inchesThe mass of the films is calculated as:
Mass = Density * Volume
This gives
Mass = 7.6 * 965 g
Evaluate
Mass = 7334 g
Express as kg
Mass = 7.334 kg
The unit cost is:
Unit cost = $0.34 per kilogram
The number of films is
n = 325
So, the total cost
Total = 325 * 0.34 * 7.334
Evaluate
Total = 810.41
Hence, the cost of the films is $810.41
