find the dimension of A34×b41 matrix]
A34 should represent either a square matrix with number of columns=number of rows =34 or the 4th element in the 3rd row in the matrix A [which is not possible in the given matrix since each row has only 3 elements]
The dimension of a matrix is given as (the number of rows it has, say a) x (the number of columns it has, say b) [read as a by b].. The given matrix has 4 rows and 3 columns, so its dimension is 4x3.
For a matrix A of dimension axb to be multiplied with a matrix B of dimension cxd, the number of columns of matrix A should be equal to the number of rows of matrix B, that is b = c should be satisfied. In this case both matrices are of the same dimension 2x3 but 3 (number of columns in first matrix) is not equal to 2 (number of rows in second matirx). So these matrices cannot be multiplied as their dimensions do not match.

It has a volume of 6 cubic units.
It has a volume of 1 cubic unit.
It has a volume of 3 cubic units.
It is called a "one block."
It can be used to measure volume.
It is called a "unit cube."
The answer to the mentioned statement are :
first statement is WRONG
the second statement is RIGHT
The third statement is also WRONG
the fourth statement is RIGHT

The current total bid for Empire design is $3,060,000The current total bid for Build-EM-UP-CO is $ 3,120,000.What is a bid?Bidding is an individual or business's offer to establish a price for a product or service or a demand that something be done. Bidding is a method of determining the price or worth of something. Bidding may be done by a person who is influenced by a product or service in a given setting.
The calculations are given as follows:
Given:
Proposal of Empire design:
$30000 x b
$ 60000/ I beam
Proposal of Build-EM-UP-CO.
$32000 x b
$ 40000/ I beam
Empire Design
Since b = 9ft; and number of I beams = 6, Hence
Total bid = (300,000 * 9) + (60,000 * 6)
= $3,060,000
Build-EM-UP-CO.
Recall that b = 9ft; and number of I beams = 6, Hence
Total Bid = (320,000 * 9) + (40,000 * 6)
Therefore,
Total bid = $3,120,000.

The ratio of one variable quantity to another that is always constant and to which it is proportional is known as the constant of proportionality then the constant of proportionality exists r = 1.6.
What is meant by constant of proportionality?The ratio of one variable quantity to another that is always constant and to which it is proportional is known as the constant of proportionality.
Given
x y
0.5. 0.8
1. 1.6
3. 4.8
25. 40
To estimate the constant of proportionality uses the following formula:
y = r x
Where r is the constant of proportionality;
Simplify the value of r, we get
r = y/x
Substitute the values of x = 0.5 and y = 0.8, in the above equation then
r = 0.8/0.5
r = 1.6
When x = 1 ; y = 1.6
r = 1.6/1
r = 1.6
When x = 3; y = 4.8
r = 4.8/3
r = 1.6
When x = 25 ; y = 40
r = 40/25
r = 1.6
The value of r exists constant.
Therefore, the constant of proportionality exists r = 1.6.

The value of variable x and y are 24 and 19 respectively.
How to find angles?We have to find the variables x and y of the angles.
Therefore,
using angles in a triangle,
2x + 13 + 47 + 5y - 23 = 180
2x + 5y = 180 - 13 - 47 + 23
2x + 5y = 143
Using corresponding angles,
180 - (2x + 13) = 47 + 3x
180 - 2x - 13 = 47 + 3x
180 - 47 - 13 = 3x + 2x
120 = 5x
x = 120 / 5
x = 24
Hence,
2(24) + 5y = 143
5y = 143 - 48
5y = 95

======================================================
Work Shown:
As you mentioned, we'll use Pythagoras' Theorem aka Pythagorean Theorem.
[tex]a^2+b^2 = c^2\\\\(x+3)^2+(4(x+2))^2 = 25^2\\\\(x+3)^2+16(x+2)^2 = 625\\\\(x^2+6x+9)+16(x^2+4x+4) = 625\\\\x^2+6x+9+16x^2+64x+64 = 625\\\\17x^2+70x+73 = 625\\\\17x^2+70x+73-625 = 0\\\\17x^2+70x-552 = 0\\\\[/tex]
Next, we'll use the quadratic formula with a = 17, b = 70, c = -552.
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-70\pm\sqrt{(70)^2-4(17)(-552)}}{2(17)}\\\\x = \frac{-70\pm\sqrt{42436}}{34}\\\\x = \frac{-70\pm206}{34}\\\\x = \frac{-70+206}{34} \ \text{ or } \ x = \frac{-70-206}{34}\\\\x = \frac{136}{34} \ \text{ or } \ x = \frac{-276}{34}\\\\x = 4 \ \text{ or } \ x \approx -8.1176\\\\[/tex]
Ignore the negative x value solution. The sides (x+3) and 4(x+2) will be negative values if we plugged in x = -8.1176, but negative side lengths do not make sense.
This makes x = 4 the only possible solution.

In the figure ZX = 2x + 1 YW = 3x - 1 and YX = 1, find perimeter of VYZ
The perimeter of triangle VYZ is 12 units.
How to find the perimeter of a triangle?The perimeter of a triangle is the sum of the whole sides of the triangle.
In other words, the perimeter of a triangle is the total distance covered by its boundaries or the sides.
Therefore,
perimeter of ΔVYZ = VY + ZY + ZV
Therefore,
VY = ZY = ZV = XW
Hence,
YW = YX + XW
Therefore,
XW = YW - YX
YW = 3x - 1
YX = 1
Hence,
XW = 3x - 1 - 1
XW = 3x - 2
Therefore,
perimeter of ΔVYZ = 3x - 2 + 3x - 2 + 3x - 2
perimeter of ΔVYZ = 9x - 6
ZX = YW
2x + 1 = 3x - 1
2x - 3x = - 1 - 1
