The width of the automobile parking space is 52.8 meters.
First, we want to convert the duration of the second one base from centimeters to meters
3760 cm = 37.6 m
Subsequent, we're suitable to use the system for the vicinity of a trapezoid
A = ( b1 b2) h/ 2
In which b1 and b2 are the lengths of the two bases, h is the height( or range) of the trapezoid, and A is the area.
Substituting the given values, we have
= (73.437.6) h/ 2
= 111h/ 2
Multiplying both angles through 2 and dividing by 111, we get
h = 52.8
Hence, the width of the automobile parking space is 52.8 meters.

You put $200 at the end of each month in an investment plan that pays an APR of 4. 5%. How much will you have after 18 years? Compare this amount to the total deposits made over the time period.
a.
$66,370. 35; $43,200
c.
$66,380. 12; $43,000
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:
$200 x 12 x 18 = $43,200
Hence the correct option is (d).

Answer options:
1. Groundwater
2. Predators & animals that eat bones.
3. Scavengers & plants that use the nutrients of fossils.
4. Other animals of the same species as the organism that died.
The abiotic factor that can prevent the organism from becoming preserved, AFTER it has been buried is groundwater.
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.

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)

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

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
Stock sold at 23 7/8 at the start of
trading. It was up 3 1/2 points at the
end of trading. What was the price
at the end of trading?
Answer:
To solve the problem, we need to add 23 7/8 and 3 1/2 to find the final price.
First, we need to convert 3 1/2 to an improper fraction:
3 1/2 = (2 x 3) + 1/2 = 7/2
Next, we need to find a common denominator between 8 and 2:
8 = 8/1
2 = 2/1 x 4/4 = 8/4
Now we can add the two fractions:
23 7/8 + 3 1/2
= 23 14/16 + 3 8/16 (using 16 as the common denominator)
= 27 6/16
= 27 3/8
Therefore, the stock was priced at $27 3/8 at the end of trading.
Prove that the commutator is bilinear: [cA+dB. C]=c[A. C]+d[B. C]
As we proved that the commutator [cA+dB. C]=c[A. C]+d[B. C] is bilinear
Let us start with the left-hand side of the equation: [cA + dB, C]. By definition, this is equal to (cA + dB)C - C(cA + dB).
Using the distributive property of multiplication, we can expand this expression to get
=> cAC + dBC - cCA - dBC.
Now let us consider the right-hand side of the equation:
=> c[A,C] + d[B,C].
By definition,
=> [A,C] = AC - CA and [B,C] = BC - CB.
Substituting these expressions into the right-hand side of the equation, we get
=> c(AC - CA) + d(BC - CB).
Using the distributive property of multiplication, we can expand this expression to get

What is area?Area is a mathematical concept that describes the size of a two-dimensional surface. It is a measure of the amount of space inside a closed shape, such as a rectangle, circle, or triangle, and is typically expressed in square units, such as square feet or square meters. The area of a shape is calculated by multiplying the length of one side or dimension by the length of another side or dimension. For example, the area of a rectangle can be found by multiplying its length by its width. The concept of area is used in many fields, including mathematics, geometry, engineering, and architecture. It is an important measure for determining the amount of material needed to cover a surface, such as carpet or paint, and is used in a wide variety of real-world applications.
Here,
To find the cost of carpeting the hallway, we need to know the total area of both trapezoids in square feet. Let's assume that the trapezoids have parallel sides of length 16 and 18 feet, and a height of 6 feet.
The area of each trapezoid is given by the formula:
Area = (1/2) x (sum of parallel sides) x height
For the first trapezoid, the sum of parallel sides is 16 + 18 = 34 feet. Therefore, the area of the first trapezoid is:
Area1 = (1/2) x (16 + 18) x 6
Area1 = 102 square feet
For the second trapezoid, the sum of parallel sides is also 16 + 18 = 34 feet. Therefore, the area of the second trapezoid is:
Area2 = (1/2) x (16 + 18) x 6
Area2 = 102 square feet
The total area of both trapezoids is:
Total Area = Area1 + Area2
Total Area = 102 square feet + 102 square feet
Total Area = 204 square feet
Now that we know the area of the hallway, we can calculate the cost of carpeting it. We're told that the carpet costs $2.50 per square foot, so we can multiply the area of the hallway by the cost per square foot to find the total cost:
Total Cost = Area x Cost per square foot
Total Cost = 204 square feet x $2.50 per square foot
Total Cost = $510

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 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

A cat gave birth to 333 kittens who each had a different mass between 147147147 and 159\,\text{g}159g159, start text, g, end text. Then, the cat gave birth to a 4^{\text{th}}4 th 4, start superscript, start text, t, h, end text, end superscript kitten with a mass of 57\,\text{g}57g57, start text, g, end text.
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.

what is the answer to 1.4(x+5) +1.6x=52
Answer: x = 15
Step-by-step explanation:
Expand 1.4(x+5): 1.4x+7+1.6x = 52
Combine like terms: 3x+7 = 52
Subtract 7 from both sides: 3x = 45
Divide both sides by 3: x = 15
Answer:
The answer is x=15
Please give me Brainliest :)
1. Expand the expression
1.4x+7+1.6x=52
