Answer:
u=10
Step-by-step explanation:
Answer
u = 10
Step-by-step explanation:
For now we do not know what u equals, but we do know that 20/5 = 4, because 20/5 simplified is just 4 since the fraction means 20 ÷ 4. Now that we are back to the question, with 2/5; if you multiply by 10 the numerator will then be 20. And now the equation is true! Hope this helps!
Suppose Ms. Smith sells her 2018 Honda Fit next year. The original cost of the vehicle was $10,000. During the time she has owned the car she has taken $3,000 dollars of deprecation on it. Ms. Williams sells the car for $9,000. What is result of the transaction
Answer:
An ordinary gain of $2,000
Step-by-step explanation:
Cost of the vehicle(C)=$10,000
Depreciation(D)=$3,000
Selling price(S)=$9,000
Worth of the vehicle= Cost price - depreciation
=$10,000-3,000
=$7,000
Net worth= selling price - worth of the vehicle
=$9,000-$7,000
=$2,000
Answer:
transaction would be a profit of $ 2,000.
Step-by-step explanation:
Given:-
- The original cost of the vehicle, C = $ 10,000
- The depreciation of the vehicle until the time of selling, d = $3,000
- The price at which the vehicle is sold, S = $ 9,000
Find:-
What is result of the transaction
Solution:-
- Whenever an asset is bought the value of the asset depreciates. There are several tools and methods to estimate the amount of depreciation.
- After n years of possession of car / since manufactured the asset undergoes depreciation until its sold or salvaged.
- Here Ms Smith possessed her car for a certain amount of time t years.
- The accumulated depreciation at the time she sold her car was " d ".
- So at the point of selling her car the actual worth or value of her car was ( C* ):
C* = C - d
C* = $10,000 - $3,000
C* = $7,000
- Now her car's value is ( C* ). If she sells her for " S " higher than current asset worth then she will profit from it otherwise she would sustain a loss in her selling transaction. So the net asset worth she would have after selling her car would be:
Net Worth = S - C*
Net Worth = $9,000 - $ 7,000
Net Worth = $ 2,000
Answer: The net worth is a positive value that means she sold her car for higher value than its worth; hence, the transaction would be a profit of $ 2,000.

The number of mosquitoes in a field after a major rainfall is modeled by the function M defined by M(t)=−t3+12t2+144t , where t is the number of days after the rainfall ended and 0≤t≤18 . Using correct units, interpret the meaning of M′(15)=−171 in the context of the problem.
Answer: The rate at which mosquitoes are appearing in a field 15 days after the rainfall ended is -171. I believe this to be correct.
M'(15) = -171 means that after 15 days, the number of mosquitoes is decreasing at a rate of 171 mosquitoes per day.
Interpreting the FunctionThe function M(t) represents the number of mosquitoes in a field after t days have passed since a major rainfall. The derivative of this function, M'(t), represents the rate of change of the number of mosquitoes.
M'(15) = -171 means that after 15 days, the number of mosquitoes is decreasing at a rate of 171 mosquitoes per day. In other words, the population of mosquitoes is declining by 171 mosquitoes each day.

Please look at the two small pictures below. Here are the questions.
7. a) Write a multiplication statement to represent the algebra tiles. (picture #1)
b) If the tiles below are divided by 2x, what is the quotient?
Answer:
Part a) [tex]-2x(2x-5)[/tex]
Part b) [tex]3x+6[/tex]
Step-by-step explanation:
Part a)
I first determined what each piece in the rectangular array meant.
Then I wanted to figure out the height and the base length.
I know [tex]-x(x)=-x^2[/tex] so that is why I put those purple [tex]x[/tex]'s on top and purple [tex]-x[/tex]'s down alongside for the [tex]-x^2[/tex] pieces. To get [tex]x[/tex] when I already had [tex]-x[/tex], I needed to multiply by -1 which is why there is a -1 along the top where those [tex]x[/tex] pieces are.
So in the first question down the side of the box, we have [tex]-x+-x=-2x/tex].
Along the the top we have [tex]x+x-1-1-1-1-1=2x-5[/tex].
To find the area of the rectangle, you multiply height by base.
[tex]-2x(2x-5)[/tex].
Part b)We have six [tex]x^2[/tex]'s and twelve [tex]x[/tex]'s. So that means the polynomial represented here is [tex]6x^2+12x[/tex].
What happens if we divide that by [tex]2x[/tex].
Let's see:
[tex]\frac{6x^2+12x}{2x}[/tex]
[tex]\frac{6x^2}{2x}+\frac{12x}{2x}[/tex]
[tex]3x+6[/tex]
Answer:
A) 2x(2x - 5)
B) -(3x + 6)
Step-by-step explanation:
Each empty square represents: x²
Each filled rectangle represents: -x
Area is 4x² - 10x
There are two rows:
Each row is: 2x² - 5x = x(2x - 5)
Statement:
2x(2x - 5)
In b, there are 6 tiles of -x², and 12 tiles of -x, which makes it:
-6x² - 12x
-(6x² + 12x)
-(6x² + 12x)/2x
-[(6x²/2x) + (12x/2x)0
-(3x + 6)

The water level, measured in feet above mean sea level, of Lake Lanier in Georgia, USA, during 2012 can be modeled by the function L(t) = 0.01441t 3 − 0.4177t 2 + 2.703t + 1060.1 where t is measured in months since January 1, 2012. Estimate when the water level was highest during 2012.
Answer:
May 4th, 2012.
Step-by-step explanation:
The highest level can be found with the help of the First Derivative and Second Derivative Tests. First and second derivatives of the function are, respectively:
[tex]l'(t) = 0.04323\cdot t^{2}-0.8354\cdot t +2.703[/tex]
[tex]l''(t) = 0.08646\cdot t - 0.8354[/tex]
The First Derivative Tests consists on equalizing the first derivative to zero and finding the critical points.
[tex]0.04323\cdot t^{2}-0.8354\cdot t +2.703 = 0[/tex]
Roots are [tex]t_{1} \approx 15.672[/tex] and [tex]t_{2} \approx 4.077[/tex]. just the second root offer a realistic solution and is test by the second derivative.
[tex]l''(4.077) = -0.482[/tex] (which leads to a maximum).
Given that a year has 365 days or 12 months, the highest water level occurs at day:
[tex]n = \frac{4.077}{12} \cdot (365\,days)[/tex]
[tex]n \approx 124[/tex] (May 4th).
A) Draw a number line from 0 to 2. Then draw and label the points 2 and 0.2. B) use the number line to explain why 2 is 10 times the value of 0.2
Answer:
See attachment
Step-by-step explanation:
A) We draw the number line as shown in the attachment with intervals of 0.2 from 0 to 2.
B) Observe that, from 0 to 0.2 you move one units to get to 0.2.
From 0 to 2, on the number line with intervals of 0.2, you move 10 units from 0.
This means that:
[tex]2 = 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2[/tex]
This gives us:
[tex]2 = 0.2(1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1)[/tex]
Then finally we have:
[tex]2 = 0.2(10)[/tex]
By the commutative property of multiplication:
[tex]2 = 10 \times 0.2[/tex]
A 150-inch pipe is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece. The shorter piece is nothing inches long.
Answer:
Step-by-step explanation:150/4 = 37.5 inches small piece
150 - 37.5 = 112.5 large piece
37.5 * 4 = 150
Answer: the shorter piece is 30 inches long.
the longer piece is 120 inches long.
Step-by-step explanation:
Let x represent the length of the shorter piece.
Let y represent the length of the longer piece.
A 150-inch pipe is cut into two pieces. It means that
x + y = 150- - - - - - - -1
One piece is four times the length of the other. It means that
y = 4x
Substituting y = 4x into equation 1, it becomes
x + 4x = 150
5x = 150
x = 150/5
x = 30
y = 4x = 4 × 30
y = 120
the width of the rectangular garden is eleven feet less than the length. find the dimensions. if the area is 80 square feet
Answer:
the dimensions are;
Width = 14.5 ft
Length = 25.5 ft
Step-by-step explanation:
We are told that width is 11 feet less than length. Let Width be W and Length be L.
Thus;
W = L - 11
Area of rectangle is given by;
Area; A = 2W + 2L
Putting L - 11 for width, we have;
Area = 2(L - 11) + 2(L)
A = 2L - 22 + 2L
A = 4L - 22
Length = L
Width = W
Area = A
A =4L-22
We are told that Area is 80 square feet. Thus;
80 = 4L -22
Add 22 to both sides to give;
102 = 4L
Divide both sides by 4 to give;
102/4 = 4L/4
L = 25.5
Recall that; W = L - 11
Thus;
W = 25.5 - 11 = 14.5
So the dimensions are;
Width = 14.5 ft
Length = 25.5 ft

Answer: i believe it is bailey
Step-by-step explanation:
bailey bought 6 note books for 10.80
thats about $1.8 per notebook
bc 10.80 ÷ 6 = 1.8
if we take steve's which is 7.28 for, four note books
thats $1.82 per note book
7.28 ÷ 4 = 1.82
then we check what it would be if he bought 6 note books.
1.82 x 6 = 10.92

You are running a concession stand at a basketball game. You are selling hot
dogs and sodas. Each hot dog costs $1.50 and each soda costs $0.50. At the
end of the night you made a total of $78.50. You sold a total of 87 hot dogs and
sodas combined. You must report the number of hot dogs sold and the
number of sodas sold. How many hot dogs were sold and how many sodas
were sold:
Let x = the number of hot dogs sold
Let y = the number of sodas sold
write your answer as an ordered pair (x,y)
x= hot dogs
y= soda
Total sold
1 x + 1 y = 87 .............1
2 x 0.50 y = 78.50 .............2
Eliminate y
multiply (1)by -0.50
Multiply (2) by 1.00
-0.50 x -0.50 y = -43.50
2 x + 0.50 y = 78.50
Add the two equations
1 x = 35.00
/ 1
x = 35.00
plug value of x in (1)
1 x + 1 y = 87
35 + y = 87
y = 87 -35
y = 52
y = 52.00
x= 35 hot dogs
y= 52 soda
Final answer:
The number of hot dogs and sodas sold can be determined using a system of linear equations. By solving these equations, it was found that 35 hot dogs and 52 sodas were sold, represented as an ordered pair (35, 52).
Explanation:
Let's solve the problem of determining the number of hot dogs (x) and sodas (y) sold at a concession stand. Given that each hot dog costs $1.50 and each soda costs $0.50, and the total revenue is $78.50 for 87 items sold, we can set up two equations:
1.50x + 0.50y = 78.50 (The revenue equation)x + y = 87 (The total items equation)Now, let's use these equations to find x and y by substitution or elimination. If we multiply the second equation by 0.50, we get:
0.50x + 0.50y = 43.50Subtract this new equation from the first one to eliminate y:
1.50x + 0.50y = 78.50-(0.50x + 0.50y = 43.50)x = 35 (Number of hot dogs sold)Now, plug x back into the second original equation:
35 + y = 87
So, y = 52 (Number of sodas sold).
The answer as an ordered pair is: (35, 52), where 35 represents the number of hot dogs sold, and 52 represents the number of sodas sold.

The number of words per page in a certain book is normally distributed with a mean of 340 words and a standard deviation of 20 words.
Approximately what percent of pages in the book are less than 360 words in length?
Answer:
Step-by-step explanation:
Since the number of words per page in the book is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = number of words per page.
µ = mean
σ = standard deviation
From the information given,
µ = 340 words
σ = 20 words
The probability that the number of pages in the book are less than 360 words in length is expressed as
P(x < 360)
For x = 360,
z = (360 - 340)/20 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.84
The percent of pages in the book that are less than 360 words in length is
0.84 × 100 = 84%
