A square field has a side length of 6x10³ meters. Which of the following is its area in square meter
(1) 6x106
(3) 36x106
(2) 36×10⁹
(4) 6x10⁹
Answer:
36 × 10^6 m²
Step-by-step explanation:
Given the side length of a square = 6 × 10³m,
To solve for the area of a square, use the following formula:
A = S² where:
S = side of the square
Substitute the given value for the side into the formula:
A = S²
A = (6 × 10³)²
A = 36000000 or 36 × 10^6 m²
NOTE:
6 × 10³ is also the same as 6 × 1000 = 6000,
(6 × 10³)² is essentially 6,000² = 36,000,000
Therefore, its area in square meters is 36 × 10^6
A price was first decreased by 12%, then it was decreased again by an additional 5%. What is the percent of the total decrease?
The answer is not 17%.
Please help!!!!
10 PTS
Answer:
83.6%
Step-by-step explanation:
Let's say the original price is x
x decreased by 12% means 88% of x is left.
0.88x decreased by 5% means 95% of 0.88x is left.
This means the answer is: 0.88x * 0.95 = 0.836
The percent of the total decrease is 83.6%

*9. The consultancy Imagination Inc. Is working with its manufacturing client Parts-R-Us to improve their on-time
performance. The firm can earn a bonus of up to $1,000,000 based on how much the on-time performance actually
improves. It's current (baseline) on-time performance is 90%.
The company typically completes approximately 1,000 orders per month, with approximately 100 orders delayed. The
bonus payment is prorated according to the following criteria:
• The on-time performance improvement is calculated based on a reduction in late events or an improvement in on-
time performance.
• No bonus is earned for the first 25% reduction in late events, say from 100 to 75. Maximum bonus is earned once
Parts-R-Us achieves 95% on-time performance.
Please answer the following:
Write down a formula to
determine the total bonus
amount to be received
Using your formula, show
how much bonus would be
paid if Parts-R-Us achieves
94% on-time performance
Parts-R-Us could be eligible for a $0 bonus if it achieves an on-time performance rate of 94% or more.
The company would have to maintain an order delivery rate of 95% in order to qualify for the bonus. If achieved, the bonus would be as follows: Bonus = 94% * (1 - 100).
The following is the calculation for the bonus:
Bonus = P * (1 - D)
Where:
P represents the proportion of orders that are delivered on time.
D represents the total number of orders placed late.
In the event that Parts-R-Us achieves an on-time performance rate of 94%, the bonus would be as follows:
Bonus = 94% * (1 - 100)
Bonus = $0
If the company only managed to complete its tasks 94% of the time, it will not be eligible for a bonus.
In order to qualify for the maximum bonus, Parts-R-Us would have to maintain an on-time delivery rate of 95%.

g a second unit vector which is also orthogonal to both 8,-8,8 and 0,5,5 is the unit vector which points in the direction opposite to u1 -2/6.-1/6,1/6 this is the vector u2
The vector u2 is (0, √3/3, 2/3). It is a unit vector that is orthogonal to both 8,-8,8 and 0,5,5.
Given two vectors 8,-8,8 and 0,5,5, we need to find another unit vector that is orthogonal to both the given vectors. Let's call this vector u1.The vector u1 can be obtained by taking the cross product of the two given vectors:u1 = (8,-8,8) × (0,5,5)u1 = (-40,-40,40)
To get a unit vector, we need to normalize u1 by dividing it by its magnitude:|u1| = √((-40)² + (-40)² + 40²) = 60u1 = (-40/60, -40/60, 40/60) = (-2/3, -2/3, 1/3)Now we need to find another unit vector that is orthogonal to u1.
One way to do this is to take the cross product of u1 with another vector, and then normalize the result. We can choose any vector that is not parallel to u1. For example, we can choose the vector (1,0,0).u2 = u1 × (1,0,0)u2 = (-2/3, -2/3, 1/3) × (1,0,0)u2 = (0,1/3,2/3)
To get a unit vector, we need to normalize u2 by dividing it by its magnitude:|u2| = √(0² + (1/3)² + (2/3)²) = 1/√3u2 = (0, √3/3, 2/3)

The length of a rectangular room is 9 feet longer than twice the width. If the room's perimeter is 150 feet, what are the room's dimensions?
Answer:
Length = 53 feet
Width = 22 feet
Step-by-step explanation:
Perimeter = 2(length + width)
Then:
a = 2w + 9 Ec. 1
150 = 2(a + w) Ec. 2
a = length
w = width
From Eq. 1:
a - 9 = 2w Eq. 3
From Eq. 2:
150 = 2*a + 2*w
150 = 2a + 2w
150 - 2a = 2w Eq. 4
Equalizing Eq. 3 and Eq. 4
a - 9 = 150 - 2a
a + 2a = 150 + 9
3a = 159
a = 159/3
a = 53
From Eq. 1:
a = 2w + 9
53 = 2w + 9
53 - 9 = 2w
44 = 2w
44/2 = w
w = 22
Check:
From Eq. 2
150 = 2(a+w)
150 = 2(53+22)
150 = 2*75
which of the following is equivalent to 3/8? -0.6, square root of 100, 2/5, -2/3, 0.35217534 ...
The option in the question that is equivalent to 3/8 is 2/5.
How to calculate the equivalent of 3/8We can simplify 3/8 and 2/5 so that they have a common denominator:
3/8 = 3*(5/5)/(85/5) = 15/40
2/5 = 2(8/8)/(5*8/8) = 16/40
Since 15/40 and 16/40 have the same denominator, we can compare their numerators to see which is larger:
15/40 < 16/40
Since 16/40 is larger, we can conclude that 2/5 is greater than 3/8.
Therefore, the option that is equivalent to 3/8 is 2/5.

Square ABCD is similar to square EFGH. The ratio of AB:EF is 1:4. The area of square EFGH is 14,400ft ft squared by 2. What is AB?
The Length of AB in square ABCD is 30 feet.
Since the squares ABCD and EFGH are similar, their corresponding sides are proportional, so we can set up the following relation:
AB/EF = 1/4
We can also use the fact that the ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding sides. Therefore,
AB²/EF² = (Area of square ABCD)/(Area of square EFGH)
Substituting the given values:
AB²/EF² = (Area of square ABCD)/(14400)
Since the areas of squares are proportional to the square of their sides, we can write,
Area of square ABCD/Area of square EFGH = (AB/EF)²
Substituting this into the above equation and solving for AB, we get,
AB²/EF² = (AB/EF)²
AB² = (AB/EF)² * EF²
AB² = (1/4)² * 14400
AB² = 900
AB = 30 feet
Therefore, the length of the side AB of square ABCD is 30 feet.

The answer to the question is 334 kittens.
Given that a cat gave birth to 333 kittens who each had a different mass between 147 g and 159 g. Then the cat gave birth to a 4th kitten with a mass of 57 g.
First of all, we will find out the range of the mass of kittens. The range is given as follows;Range = Maximum Value - Minimum Value Range = 159 g - 147 g Range = 12 g
Now, the cat gave birth to a 4th kitten with a mass of 57 g, we can say that the minimum value of kitten's mass is 57 g.So, the maximum value of kitten's mass can be calculated as follows;Maximum Value = 57 g + Range Maximum Value = 57 g + 12 g Maximum Value = 69 g Now, we can say that all kittens with a mass of 69 g or less would be born because the minimum value of kitten's mass is 57 g and the range of mass is 12 g.
Therefore, the answer to the question is 334 kittens.

b.
$66,295. 23; $43,000
d.
$66,373. 60; $43,200
As per the given APR, the sum of amount after 18 years is $66,373. 60, and the total deposits made over the time period is $43,200. (option d).
To calculate this, we can use the formula for future value of an annuity:
FV = PMT x (((1 + r)⁻¹) / r)
where FV is the future value, PMT is the monthly payment, r is the monthly interest rate (which is calculated by dividing the APR by 12), and n is the number of payments (which is 18 x 12 = 216 in this case).
Plugging in the numbers, we get:
FV = $200 x (((1 + 0.045/12)²¹⁶ - 1) / (0.045/12)) = $66,373.60
Therefore, you would have approximately $66,373.60 in your investment plan after 18 years.
Now let's compare this amount to the total deposits made over the time period. In this case, the total deposits would be:

The population of a place is increased to 54000 in year 2003 5% per annum find the population in the year 2001 what would be the population in the year 2005
Answer:
To find the population in the year 2001, we need to work backwards from the given population of 54,000 in 2003.
Let P be the population in the year 2001. From 2001 to 2003, there are two years, during which the population grows at a rate of 5% per annum. We can calculate the population in 2003 using the formula:
P * (1 + r)^n = 54,000
where r is the annual growth rate (5% or 0.05) and n is the number of years (2). Plugging in the values, we get:
P * (1 + 0.05)^2 = 54,000
Simplifying the equation, we get:
P = 54,000 / (1.05)^2
P = 48,543 (rounded to the nearest whole number)
Therefore, the population in the year 2001 was approximately 48,543.
To find the population in the year 2005, we can use the same formula with n = 2 + 2 = 4 (since we want to find the population four years after 2001):
P * (1 + 0.05)^4 = ?
Plugging in the value of P we just found, we get:
48,543 * (1 + 0.05)^4 = 60,723 (rounded to the nearest whole number)
Therefore, the population in the year 2005 would be approximately 60,723

What is an abiotic factor that can prevent the organism from becoming preserved, AFTER it has been buried?An abiotic factor refers to a non-living component of an ecosystem that influences the survival and growth of living organisms.
Groundwater can cause the dissolution of minerals present in the sediment that encases the buried organism.
This process can lead to the destruction of the fossilized remains, as the minerals provide the framework for the preservation of the organism's hard parts (such as bones or shells).
Groundwater can also cause the erosion of the sediment, which can expose the buried remains and make them vulnerable to biotic factors such as scavengers, predators, and decomposers.
Predators and animals that eat bones, scavengers and plants that use the nutrients of fossils, and other animals of the same species as the organism that died are all biotic factors that can affect the preservation of the organism, but they do so before or during the burial process.

60 identical machines in a factory pack 150 crates of limes per day
between them.
a) Write the ratio of the number of machines to the number of crates
packed per day in the form 1: n.
b) How many crates of limes would 70 of these machines pack per day?
Give any decimals in your answers to 1 d.p.
a) To write the ratio of the number of machines to the number of crates packed per day in the form 1: n, we need to find the number of crates packed per day per machine. We can do this by dividing the total number of crates packed per day by the number of machines:
Number of crates packed per day per machine = 150 crates/day ÷ 60 machines = 2.5 crates/machine/day
Therefore, the ratio of the number of machines to the number of crates packed per day in the form 1: n is 1:2.5 or 2:5.
b) To find out how many crates of limes 70 of these machines would pack per day, we can use the ratio from part (a) to set up a proportion:
1 machine : 2.5 crates/day = 70 machines : x crates/day
Solving for x, we get:
x = (70 machines × 2.5 crates/day) / 1 machine = 175 crates/day
Therefore, 70 of these machines would pack 175 crates of limes per day.
Step-by-step explanation:
a) The ratio of the number of machines to the number of crates packed per day can be written as:
60 : 150
To simplify this ratio, we can divide both sides by 10:
6 : 15
Finally, we can divide both sides by 3 to get the ratio in the form 1 : n:
1 : 2.5
Therefore, the ratio of the number of machines to the number of crates packed per day is 1 : 2.5.
b) If 60 machines can pack 150 crates per day, then one machine can pack:
150/60 = 2.5 crates per day
So, 70 machines can pack:
70 × 2.5 = 175 crates per day
Therefore, 70 machines can pack 175 crates of limes per day.

What is the slope of the line passing through the points (4, -6) and (2, 3)?
Answer:
m = -9/2
Step-by-step explanation:
Slope = rise/run or (y2 - y1) / (x2 - x1)
Points (4, -6) (2, 3)
We see the y increase by 9, and the x decrease by 2, so the slope is
m = -9/2

A system of equations is graphed on the coordinate plane. A student concludes that the solution of the system is (-0.5, 1.5). Is this correct? Justify your response.To conclude that a system of equations has a solution in the coordinate plane, a set of ordered pairs (x, y) should satisfy both equations in the system of equations. That is, the system of equations should have a point (x, y) that is a solution of both equations.Only by testing the solution in the given system of equations can we know if the student's conclusion is correct. If the solution is satisfied by the system of equations, then the answer is true. Otherwise, it is false. However, since no system of equations is provided in the question, we cannot test the student's solution.To justify the correctness of the student's solution, we need to have the equations of the system.

three cards are drawn with replacement from a standard deck of 52 cards. find the the probability that the first card will be a diamond, the second card will be a black card, and the third card will be a face card. express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
The probability of drawing a diamond, then a black card, and then a face card from a standard deck of 52 cards with replacement is 3/104 or 0.028846 .
What is the probability?The probability that the first card will be a diamond, the second card will be a black card, and the third card will be a face card is given by the expression, `(13/52) × (26/52) × (12/52)`.
In a standard deck of 52 cards, there are 13 diamonds, 26 black cards (13 clubs and 13 spades), and 12 face cards (4 Jacks, 4 Queens, and 4 Kings).
To calculate the probability that the first card will be a diamond, the second card will be a black card, and the third card will be a face card, we use the formula of probability:
`P(E) = n(E) / n(S)`
where, P(E) = Probability of an event
n(E) = Number of favorable outcomes
n(S) = Total number of outcomes
Total number of outcomes = 52
First card will be a diamond
Number of diamonds in a deck of 52 cards = 13
Total number of outcomes after drawing the first card = 52
Probability of drawing a diamond in the first attempt = P(diamond)`= 13/52
Probability of drawing a black card in the second attempt, given that the first card is a diamond= `P(black/diamond)`= (26/52) = `(1/2)`
Probability of drawing a face card in the third attempt, given that the first card is a diamond and second card is a black card= `P(face/diamond and black)`= `(12/52)` = `(3/13)`
Therefore, probability that the first card will be a diamond, the second card will be a black card, and the third card will be a face card`= P(diamond) × P(black/diamond) × P(face/diamond and black) = (13/52) × (1/2) × (3/13)= 3/104`
Therefore, the required probability is 3/104 or 0.028846 rounded to the nearest millionth.

suppose the minimum volume of a clown is 60,000 cm3 and the volume of my car is 3 million cm3. 55 is______ the maximum number of clowns that can fit in my car.
a. An upper bound on
b. Not a bound
c. A lower bound on
d. exactly
When the minimum volume of a clown is 60,000 cm³ and the volume of a car is 3 million cm³, 55 is an upper bound on the maximum number of clowns that can fit in a car. The correct answer is Option A.
What are bounds?Bounds are the maximum and minimum limits that are permitted, within which something can or must be performed. Bounds are used to refer to an acceptable range of values that provide safe operation or performance. In mathematics, a set of bounds can define the limits of the amount of things or objects.
The minimum volume of a clown is 60,000 cm³, so to fit 55 clowns in a car we need:
55 clowns × 60,000 cm³/clown = 3,300,000 cm³
This is lower than the volume of the car. Therefore, 55 is an upper bound on the maximum number of clowns that can fit in the car.

The cat population in catonsville has been recorded since 2010. The population. p. can be represented by the equation p = 1600(2)t where is time in years since the begging of 2010. What was that cat population 2007
A. 4000
B. 200
C. 800
D. 100
The cat population in Catonsville in 2007 was 200. The answer is option B.
What is population?Population refers to the total number of people, animals, or objects in a particular group or area. It is the entire group or collection of individuals, things, or events that we are interested in studying or describing.
According to question:We can use the given equation to find the cat population at any given time in years since the beginning of 2010. However, to find the population in 2007, we need to make a conversion from years since the beginning of 2010 to years since the beginning of 2007.
From the beginning of 2007 to the beginning of 2010, there are 3 years, so if we subtract 3 from the number of years since the beginning of 2010, we will get the number of years since the beginning of 2007. Therefore, we need to substitute t = -3 into the given equation and solve for p:
[tex]p = 1600(2)^t\\p = 1600(2)^(-3)\\p = 1600(1/8)\\p = 200[/tex]
Therefore, the cat population in Catonsville in 2007 was 200. The answer is option B.

A certain computer loses half of its value every four years. If the value of the computer after 6 years is $835, what was the initial value of the computer?
The PC is initially worth $3,340.
Given that a computer loses half of its worth after six years, and assuming that value is $835, we must determine the device's original value.
What does the term "starting value" mean?
The starting output value is the initial value.
Let's say that computer's starting value is x.
As a result, after four years,
It is X/2 for the fourth year.
It is X/2 for the fifth year.
It's X/4 in the sixth year.
We stated that the PC will be worth $835 after six years. Hence, we may express it as,
X/4 = $835
X=4( $835)
X= $3,340
Hence, the initial value of the computer is $3,340.
