Answer:

144 cm²

Step-by-step explanation:

Remember: If you are finding the area of a square and are given a side, you can simply square it and it will be the area. Thus:

12 x 12 cm = Area of tile.

=> 144 cm² = Area of tile.

Therefore, 144 cm² is the area.

The approximate reciprocal of 0.72 is 1.3889.

The ✓1.7 depicted as a fraction is (√170)/10.

It should be noted that to calculate the reciprocal of 0.72, we simply divide 1 by 0.72:

1/0.72 = 1.388888888888889

Thus, the approximate reciprocal of 0.72 is 1.3889.

Also, to determine the fractional equivalent for √1.7, we may again rationalize the denominator through multiplying both numerator and denominator with the expression contained beneath the radical:

√1.7=√(17/10)=(√17)/(√10)

Multiplying every entity within the adjoined numerator and denominator with (√10) offers:

(√17)/(√10)*(√10)/(√10)= (√170)/10

Therefore, √1.7 depicted as a fraction is:

√1.7=(√170)/10

9 non-congruent squares can be drawn.

Non-congruent squares are two squares with different side lengths. These two squares can be drawn separately and still have four right angles and four equal sides, but the lengths of the sides are not the same. Non-congruent squares are a type of quadrilateral and have both diagonals and parallel sides. These shapes can be used to create a variety of geometric designs and patterns, and often appear in art and architecture.

Each of the four corners of the 5 by 5 grid can be the vertices of a square, and the middle of each side of the 5 by 5 grid can be the vertices of a square. This makes eight non-congruent squares in total. Additionally, the center point can be the vertex of another non-congruent square, making nine in total. All of these squares are constructed from lattice points, and none of them are congruent to each other.

Step-by-step explanation:

Answer:

Tom kept 20 portugals for himself.

Step-by-step explanation:

Let "n" be the number of portugals Tom kept for himself, then...

# of portugals which he gave to Ryan = n - 5

# of portugals which he gave to Neil = Ryan's portugals - 3 = (n - 5) - 3 = n - 8

Now, we know that...

Tom's  portugals + Ryan's  portugals + Neil's  portugals = 47

Now substatute the values and get...

n + (n - 5) + (n - 8) = 47

n + n - 5 + n - 8 = 47

3n - 13 = 47

3n = 47 + 13

3n = 60

n = 20

Therefore Tom kept 20 portugals for himself.

Answer:

Sure, here are the answers to your questions:

a. The maximum value of f(x,y) is 674.

b. The point(s) where the function attains its maximum are (-6,3) and (6,3).

c. The minimum value of f(x,y) is -5.

d. The point(s) where the function attains its minimum are (0,0) and (-3,-1).

Here are the steps on how I got the answers:

First, we need to find the critical points of the function. This can be done by finding the points where the gradient is equal to zero.

The gradient of f(x,y) is given by the following vector:

∇f(x,y) = (4x - 4, 6y)

Setting this vector equal to zero, we get the following system of equations:

4x - 4 = 0

6y = 0

Solving this system of equations, we get the following critical points:

(-6,3)

(6,3)

Next, we need to evaluate the function at each critical point and at the boundary points of the domain.

The boundary points of the domain are given by the following points:

(-13,0)

(13,0)

(0,-13)

(0,13)

Evaluating the function at each of these points, we get the following values:

f(-13,0) = -674

f(13,0) = -674

f(0,-13) = -674

f(0,13) = -674

f(-6,3) = 674

f(6,3) = 674

f(0,0) = -5

f(-3,-1) = -5

Finally, we need to compare the values of the function at the critical points and at the boundary points to find the maximum and minimum values.

The maximum value of the function is 674, which is attained at the points (-6,3) and (6,3).

The minimum value of the function is -5, which is attained at the points (0,0) and (-3,-1)

Step-by-step explanation:

The required number of sessions is obtained as 2.

A linear equation can be balanced by adding or subtracting the same number on both sides of the equality sign. Similarly, multiplication and division is also possible with the same numbers.

Suppose the number of sessions be x.

Then, the expression for the training cost as per the first plan is given as 41 + 83x.

And, for the another plan it is 43x + 82.

As per the question both the expressions has to be equated for the same cost as follows,

43 + 82x = 41 + 83x

=> 43 - 41 = 83x - 82x

=> x = 2

Hence, the number of sessions for both the plans to have same cost is 2.

The length of the line segment is given by the distance equation

D = 7.2 units

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Given data ,

Let the distance of the line segment between two points be D

Now , the equation will be

Let the first point be represented as P ( 1 , 6 )

Let the second point be represented as Q ( 7 , 2 )

Now , distance between P and Q is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

D = √ ( 1 - 7 )² + ( 6 - 2 )²

On simplifying the equation , we get

D = √ ( -6 )² + ( 4 )²

D = √ ( 36 + 16 )

D = √ 52

D = 7.2 units

Step-by-step explanation:

i did 3.5 x 3.14 = 10.99 and rounded to the nearest whole number, 11.

The circumference of the circular window to the nearest whole number is 11 feet.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is pir^2.

We have,

To find the circumference of the circular window, we need to use the formula:

C = πd

where C is the circumference, π is the constant pi, and d is the diameter of the circle.

Since the window is 3.5 feet across at its widest point, the diameter of the circle is also 3.5 feet.

Plugging in the value of the diameter in the formula, we get:

C = πd

C = 3.14 x 3.5

C = 10.99

Rounding the result to the nearest whole number, we get:

C ≈ 11 feet

sin A or cos C

Step-by-step explanation:

Assuming that the length of BC is 4cm (it looks like a 6, sort of):

Looking at Angle A, the side labeled 4 is OPPOSITE angle A, and AC is the hypotenuse. The trig ratio that involves the opposite side and the hypotenuse is sine.

sin A = (opposite) / (hypotenuse) = 4 / 8.

Looking at angle C, the side labeled 4 is ADJACENT ("next to") angle C. The trig ratio involving the adjacent side and the hypotenuse is cosine.

cos C = (adjacent) / (hypotenuse) = 4 / 8.

Sister's money saved should equal x.

James has saved only half as much money as his sister.

James saved x/2 in money.

They both saved a total of x + x/2 dollars.

If they each save thirty more

Then

sisters' money = x + 30

cash with James = x/2 + 30

Given that James will have saved half as much as her sister if they both save 30 more

thus,

James and money equals 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

=> 4(x+30*2) /2 = 3x+90

=> 2x + 120 = 3x + 90

=> 3x-2x = 120-90

Collider bias occurs when exposure and outcome each influence a common third variable, and that variable or collider is controlled in the study design or analysis.

3 is the minimum number of guesses required to guarantee that you know the number.

If we use a binary search approach, we can guess the number in a minimum number of steps.

First, we guess the middle number, which is 8. If the answer is higher, we can eliminate all the numbers from 1 to 8, because they are lower than the answer.

Then we guess the middle number of the remaining numbers, which is 12. If the answer is lower, we can eliminate all the numbers from 12 to 15, because they are higher than the answer.

We have now eliminated half of the remaining numbers, and we are left with 6 and 7. We can guess either of these numbers, and we will know the answer with a total of three guesses.

Symmetric polynomials are polynomials that are invariant under permutation of their variables. A symmetric presentation is a way of expressing a symmetric polynomial as a sum of elementary symmetric polynomials, which are defined as the sum of all possible products of variables taken i at a time, where i ranges from 1 to the number of variables. For example, the symmetric polynomial x^3 + y^3 + z^3 can be expressed as a symmetric presentation of x + y + z.
