Step-by-step explanation:
-A 10 kg iron plate contains 2000 I potential energy at a height. find out its heigt
Assuming that the iron plate is lifted to a height against the gravitational force, we can use the formula for potential energy:
Potential Energy = mass x gravity x height
where mass is in kg, gravity is 9.81 m/s^2, and height is in meters.
Rearranging the formula to solve for height, we have:
height = Potential Energy / (mass x gravity)
Plugging in the given values, we have:
height = 2000 J / (10 kg x 9.81 m/s^2)
height = 20.34 meters (rounded to two decimal places)
Therefore, the height of the iron plate is approximately 20.34 meters.
if the matrix M is a linear combination of the matrices Mi, M2 and M3:M = [2 3 ] [1 2 ]M1 = [ 2 2 ][ 1 1 ] M2 = [ -1 1 ][ 2 1 ]M3 = [ 1 2 ] [ 3 1 ]if so, determine scalars c1, c2, c3 such that c1M1 + c2M2 +C2M3 = M.
The scalars c1 = 2/5, c2 = -3/5, and c3 = -8/5 satisfy the equation:
c1M1 + c2M2 + c3M3 = [ 2 3 ][ 1 2 ]
We want to find the scalars c1, c2, and c3 such that:
c1M1 + c2M2 + c3M3 = M
Substituting the given matrices:
c1[ 2 2 ] c2[ -1 1 ] c3[ 1 2 ] [ 2 3 ]
[ 1 1 ] [ 2 1 ] [ 3 1 ] [ 1 2 ]
Multiplying each scalar by its corresponding matrix:
[ 2c1 - c2 + c3 2c1 + 2c2 + 3c3 ]
[ c1 + 2c2 + 3c3 c1 + c2 + 2c3 ]
Setting the result equal to M:
[ 2c1 - c2 + c3 2c1 + 2c2 + 3c3 ] = [ 2 3 ]
[ c1 + 2c2 + 3c3 c1 + c2 + 2c3 ] [ 1 2 ]
This gives us two equations:
2c1 - c2 + c3 = 2
2c1 + 2c2 + 3c3 = 3
c1 + 2c2 + 3c3 = 1
c1 + c2 + 2c3 = 2
We can solve this system of equations using any method we prefer, such as elimination or substitution. Here, we will use elimination.
Subtracting the first equation from the second, we get:
3c2 + 4c3 = 1
Subtracting the third equation from fourth, we get:
c2 - c3 = 1
Multiplying second equation by 2, we get:
4c1 + 4c2 + 6c3 = 6
Subtracting first equation from this, we get:
5c2 + 5c3 = 4
Now we have three equations for c2 and c3:
3c2 + 4c3 = 1
c2 - c3 = 1
5c2 + 5c3 = 4
Solving for c2 and c3 using elimination, we get:
c2 = -3/5
c3 = -8/5
Substituting these values into the third equation, we get:
c1 = 2/5

Answer:
b = 70 degrees
Step-by-step explanation:
A triangle has a total of 180 degrees.
We know 2 angles, one is 80 degrees, and one is 30 degrees.
80 + 30 = 110 degrees.
180 - 110 = 70 degrees
So, b = 70 degrees.
An Airplane flies in the path shown by the vector PQ on the graph below. What is the magnitude and direction of PQ (1 unit represents 1 mile)
a. 80.5 east of south for 6 miles
b. 80.5 west of north for 7 miles
c. 9.5 south of west for 6.1 miles
d. 9.5 north of east for 6.1 miles
Based on the data, it can be inferred that the magnitude and direction of PQ is 9.5 north of east for 6.1 miles (option D).
How to identify the magnitude and direction of the plane?To identify the magnitude and direction of the plane, we must carefully look at the information in the graph and identify the option that corresponds to the information.
So, we can say that this is moving from the south to the north and from the west to the east, so options A and C would be ruled out. Now we must identify the magnitude and degrees. Taking a completely horizontal line as a reference, we could say that the plane has 9.5 degrees in its trajectory. So the correct option would be D.

The amount of lumber in a tract of timber, an owner randomly selected seventy 50-by-50-foot squares, and counted the number of trees with diameters exceeding 12 inches in each square is 16.67
In order to estimate the amount of lumber in a tract of timber, an owner will use a technique called sample size estimation.
By using this data, the owner can then calculate an estimate of the total amount of lumber present in the tract of timber.
In this case, the sample size is 70, the square size is 2500 square feet, and the diameter of the trees is 12 inches. Therefore, the formula becomes:
=> Total Trees = (Number of Trees in Sample / 70) x (2500 / 12).
If we plug in the number of trees counted in each square, we can find the total estimated number of trees in the tract of timber.
If the owner counted 7 trees in the first square, the formula would be
=> (7 / 70) x (2500 / 12) = 16.67.

karen bought some clothes that were on sale. she paid $85 after the 15% off what was the original cost of the clothing
Karen received a 15% discount of $15, which brought the price down to $85.
How to determine the original priceLet's assume the original cost of the clothes was x dollars.
If Karen got a 15% discount, then she paid 85% of the original price.
This can be expressed in an equation as:
0.85x = 85
To find x, we need to isolate it on one side of the equation.

To find the minimum score you would need to be in the top 4%, we need to use the standard normal distribution and the given z-score.
First, we find the z-score corresponding to the top 4% using a standard normal distribution table or a calculator:
z = invNorm(1 - 0.04) = invNorm(0.96) = 1.7507 (rounded to four decimal places)
The minimum score needed to be in the top 4% is the score that corresponds to this z-score in the distribution of exam scores. We can use the formula for standardizing a normal random variable to find this score:
z = (X - μ) / σ
where X is the exam score, μ is the mean of the exam scores, and σ is the standard deviation of the exam scores.
Solving for X, we get:
X = zσ + μ = 1.75076.1 + 76.4 = 87.46

area of the yard that can be mowed?
xn
The factor that represents the area of the yard that can be mowed is (225 - x²).
What is area?
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
The total area of the lawn is given by the formula -
Area of square lawn = (side length of square lawn)²
= (15 yards)²
= 225 square yards
The shed is also a square, with side length x yards.
So, the area of the shed is -
Area of square shed = (side length of square shed)²
= x²
To find the area of the yard that can be mowed, we need to subtract the area of the shed from the total area of the lawn -
Area of yard that can be mowed = Area of square lawn - Area of square shed
= 225 - x²
Therefore, the value is obtained as (225 - x²).

1. To solve number 1 we need to find a common denominator.
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator.
[tex]\frac{3}{4} =\frac{6}{8}[/tex]
How can we convert this? Well, to go from 4 to 8, we multiply by 2. Doing the same to the top number (Numerator) will get us a fraction of [tex]\frac{6}{8}[/tex].
Adding the two fractions together:
[tex]\frac{7}{8} +\frac{6}{8}= \frac{13}{8} or1 \frac{5}{8}[/tex]
Therefore, the answer to question 1 is [tex]1\frac{5}{8}[/tex].
2. If there are 60 students in a class, and [tex]\frac{3}{4}[/tex] of them are girls, we can use this equation to solve for the number of girls in the class:
60 × 0.75 = 45Why do we multiply by 0.75?We multiply by 0.75 because 0.75 is equivalent to [tex]\frac{3}{4}[/tex].
So, there are 45 girls in the class.
To solve for the rest of the class that are boys, we can use this equation:
60 - 45 = 15The answer to question 2 is 15 boys.
3. If the temperature was -2°C, and it is now 8°C, we can use this equation to solve for the temperature difference:
-2 + 10 = 8So, the temperature difference is 10°C.
4. If Mt. Everest's elevation is at 29,028 feet, and the dead sea is -458, we can use this equation to solve for the difference in elevation:
29,028 + 458 = 29,486Therefore, the difference in elevation is 29,486 feet.
When filling out a W-4 form, in what situation would a teen want to claim exemption from federal income taxes being withheld from their paycheck? What is the benefit of doing so?
The benefit of doing so is: If the teenager has earned less than $12,000 then they don't get the federal taxes withheld. It would be beneficial to the teen because they would get more money.
A teen might want to claim exemption from federal income taxes being withheld from their paycheck if they expect to earn less than the standard deduction amount for the tax year and they will not owe any federal income tax.
For the tax year 2022, the standard deduction amount for a single taxpayer who is not claimed as a dependent on another taxpayer's return is $12,950.
By claiming exemption from federal income taxes, the teen would have more money in their paycheck and would not have to wait to receive a tax refund when they file their tax return at the end of the year.
However, if the teen ends up earning more than the standard deduction amount or if they have other sources of taxable income, they may owe federal income tax and may have to pay a penalty for not having enough taxes withheld during the year.

The median is 25.5, and it represents the difference in the lowest and highest ages of runners. The median is 28.5, and it represents the difference in the lowest and highest ages of runners.
The median age of the runners is 23.5.
What does "median" mean?By adding up all the numbers in a data collection and dividing by the total number of values in the set, the mean (average) of the data set can be determined. The median is the middle when a data set is sorted from least to greatest.
We must first arrange the ages from youngest to oldest in order to determine the median:
14, 15, 16, 19, 19, 23, 24, 27, 30, 31, 31, 33
The median will be the average of the sixth and seventh values in this sorted list because there are 12 runners:
(23 + 24) / 2 = 23.5 is the median.
Hence, 23.5 is the runners' median age.
The median, in terms of meaning, is the data set's middle value. In this instance, the age is the exact midpoint between the ages of the 12 racers. It is a central tendency index that shows how typical or representative the data are.
In this situation, the median age of 23.5 can be interpreted as the typical age of the marathon runners. Half of the runners were over 23.5 years old, and half were under that age. Although the middle figure is closer to the lower end of the age spectrum than the higher end, it can also help us estimate the runners' age range. The disparity between the runners' lowest and highest ages is not, however, directly shown.

Study the right square pyramid and its net shown here.
Then complete the statements below to find the surface area of the pyramid.
The surface area of the square base pyramid is 736 cm².
What is surface area?Surface area is the amount of space covering the outside of a three-dimensional shape. The surface area of a solid object is a measure of the total area that the surface of the object occupies.
here, we have,
Surface area = A + 1 / 2 ps
where
A = base area
p = perimeter of the base
s = slant height
Therefore,
A = 16² = 256 cm²
p = 4(16) = 64 cm
s = 15 cm
surface area = 256 + 1 / 2 × 64 × 15
surface area = 256 + 480
surface area = 736 cm²

Add.
8/9 + 2/3 + 1/6
Answer: 31/18.
Step-by-step explanation:
To add these fractions, we need to find a common denominator. In this case, the least common multiple of 3, 6, and 9 is 18. We can convert each fraction to an equivalent fraction with a denominator of 18, and then add the numerators:
8/9 + 2/3 + 1/6
= (8/9) * (2/2) + (2/3) * (6/6) + (1/6) * (3/3) (Multiplying each fraction by a form of 1 to obtain a common denominator of 18)
= 16/18 + 12/18 + 3/18 (Simplifying each fraction by multiplying the numerators)
= 31/18 (Adding the simplified numerators)
Therefore, the sum of 8/9, 2/3, and 1/6 is 31/18.

what is substitution method calculator online
The substitution method calculator online shows the substitution method's result for the pair of linear equations.
One way to solve a system of linear equations with one or more unknown variables in mathematics is the substitution method. For the purpose of solving simultaneous equations, the substitution method is regarded as an algebraic technique. By resolving the equations, this method allows one variable's value to be determined. Any of the preceding equations can be solved by replacing the first variable's value for another variable.
The substitution technique calculator should be used as follows:
Step 1: Type the linear equations' coefficients into the input field.
Step 2: Then, select "Solve" to see the outcome.
Step 3: Lastly, the output field will show the value of the variables x and y in the linear equations solved using the substitution approach.
