The value of a car is $22,000. It loses 13.9% of its value every year. Find the approximate monthly decrease in value. Round your answer to the nearest tenth.
Answer:
.200 because 22,000 % by 7 is 1540 which you divide by 10,000
Step-by-step explanation:
hope this helps
The approximate monthly decrease in value is $255.2
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100.
Given,
Value of the car = $22000
Loss percentage of value per year = 13.9%
Loss percentage of value per month =[tex]\frac{13.9}{12}[/tex] =1.16%
Decrease in value per month = [tex]22000(\frac{1.16}{100})[/tex]= $255.2
Hence, the approximate monthly decrease in value is $255.2

The diameter of the circle is 6 miles. What is the area of the circle? Use 3.14 for II.
Answer:
28.26 miles
Step-by-step explanation:
Area= pi times radius squared
diameter is twice the radius so 6÷2=3miles
3 miles is the radius
So A= 3.14 × 3²
= 28.26
Formula: A = πr²
Divide to find the radius.
6 / 2 = 3
Solve using the values we are given and solved for.
A = π(3)²
A = 9π
A ≈ 28.26

What is the 8th term of this geometric sequence?
1, 3, 9, 27,...
Answer:
1*3*3*3*3*3*3=729. For each term you multiply the previous term by three.
Answer:
2187
Step-by-step explanation:
To find the 8th term, we can find and use the explicit formula.
The standard form of the explicit formula for a geometric sequence is:
[tex]x_n=a(r)^{n-1}[/tex]
Where a is the initial term, r is the common ratio, and n is the nth term.
From the sequence, we can see that the first term is 1, and each term is 3 times the previous term. Thus, the common ratio is 3.
Substituting these into our equation, we will have:
[tex]x_n=1(3)^{n-1}\\x_n=(3)^{n-1}[/tex]
So, to find the 8th term, substitute 8 for n:
[tex]x_8=(3)^{8-1}[/tex]
Subtract:
[tex]x_8=(3)^7[/tex]
Evaluate:
[tex]x_8=2187[/tex]
So, the 8th term is 2187.
And we're done!
A customer wants you to enlarge a photo to 2 3 4 234 its current height. The photo's current height is 3 1 4 314 inches. What should its enlarged height be, in inches? 6 6 3 16 6316 6 11 16 61116 7 8 15 16
Answer:
The question is not clearly stated, below is the clearly stated question and answer:
A customer wants you to enlarge a photo to 2 3/4 its current height. The photo’s current height is 3 1/4 inches. What should its enlarged height be, in inches?
Answer:
[tex]Enlarged\ height = 8\frac{15}{16}\ inches[/tex]
Step-by-step explanation:
[tex]current\ height\ =\ 3\frac{1}{4} = \frac{13}{4} \\ magnification\ factor = 2\frac{3}{4} = \frac{11}{4} \\Magnification (enlargement)\ =\ (magnification\ factor) \times (current\ height)\\Magnification\ =\ \frac{11}{4} \times \frac{13}{4}\\ Magnification\ =\ \frac{143}{16}[/tex]
Next, we will concert from the improper fraction to a mixed fraction:
when 143 is divided by 16, there will be 8 whole numbers and a remainder of 15, hence, the mixed fraction is:
[tex]\frac{143}{16} = 8\frac{15}{16}[/tex] (Alternatively, a scientific calculator can be used)
Therefore, enlarged height [tex]= 8\frac{15}{16}\ inches[/tex]
A student has some $1 and $5 bills in his wallet. He has a total of 19 bills and that are worth $55. how many of each type of bill does he have
Answer:
y= 9 ( 5 dollars bill)
x=10 ( one dollar bill)
Step-by-step explanation:
let x be the one dollar bill and y the 5 dollar bill
x+y=19 ⇒ x=19-y
x+5y=55 ( solve by substitute x=19-y)
19-y+5y=55
4y=55-19
4y=36 ⇒ y=36/4
y= 9 ( 5 dollars bill)
x+y=19
x+9=19
x=19-9
x=10 ( one dollar bill)
check :
x+5y=55
10+5(9)=
10+45 = 55 dollars

6) Marcy gave Juanita as many dimes as Juanita had. Then Juanita gave Marcy as many dimes as Marcy had left. Juanita now had 26 dimes and Marcy had 20 dimes. Originally, Marcy had( )dimes.
Answer:
0
Step-by-step explanation:
The original amount of dimes Marcy had before sharing with Jaunita is 52.
What is the solution to the word problem about dimes?Let's break down the given information step by step to determine the original number of dimes Marcy had.
Marcy gave Juanita as many dimes as Juanita had.
After this transaction, Juanita now has 26 dimes, and Marcy has x - 26 dimes, where x is the original number of dimes Marcy had.
Juanita gave Marcy as many dimes as Marcy had left.
After this transaction, Marcy now has 20 dimes, and Juanita has 26 - 20 = 6 dimes remaining.
From the above information, we can set up the following equation:
x - 26 = 20 + 6
Simplifying the equation:
x - 26 = 26
Adding 26 to both sides:
x = 52
Therefore, the original amount of dimes Marcy had is 52 dimes.

Rafiq compares the
expressions 4 X 8 and 8 X 12. He says that 8 is twice
as much as 4, so 4 X 8 must be twice as much as 8 X 12.
Correct his statement, and explain his error.
HELLLPPPPP
Answer:
Hey there!
Rafiq's error was that the other number is also changing. He had 4 x 8 and if he had 8 x 8, that would be twice as much, but he used 8 x 12 instead, and 12 is not 8.
Let me know if this helps :)
The other number that was also changing was Rafiq's mistake if Rafiq compares the expressions 4x8 and 8x12.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that are +, -, ×, and ÷.
It is given that:
Rafiq compares the expressions 4x8 and 8x12
The correct statement is for Rafiq compare the expressions 4 X 8 and 8 X 12
The fact that the other number was also changing was Rafiq's mistake.
Rafiq had 4 × 8, therefore 8 x 8 would have been twice as much; however, he utilized 8 x 12, even though 12 is not equal to 8.
Thus, the other number was also changing was Rafiq's mistake if Rafiq compares the expressions 4x8 and 8x12.

Dr. Watson received a $15 gift card to download music for her mp3 player. Each Song costs $1.50. Find the equation that represents the
remaining balance on the gift card after x downloads. What is a suitable domain for this function?
Answer:
y = -1.50x + 15, Domain is from 0 to 10
Step-by-step explanation:
First, look at the question carefully and highlight all the words that are important. We know that the 15 dollar giftcard is important, and we know that each song costs 1 dollar and 50 cents is important. We will make an equation out of this information. Since she is spending money, the value of X will be negated. She starts out with 15 dollars, so that will be our y-intercept. From this, the equation is y = -1.50x + 15. Next, let's look at the domain. We can see that the question asks for a suitable domain, not the domain of the function. Since she didn't have more than 15 dollars from her gift card, any domain from negative infinity until 0 will be crossed out. The x-intercept of this equation is 10, so any value above 10 will be crossed out since you cannot spend more money than you were given. The domain would now be from 1 to 10.
