Friends can you please explain me what is given in this picture, and tell me how to solve this please!..
Thank you
Answers
Step-by-step explanation:
the picture and its text explain it actually already.
each block (or square) on each side represents a fraction.
the whole block is 1. the colored parts are the fraction of that whole (1).
we see the example 2/3 × 3/4
the left block with 2 out of 3 strips marked in pink shows us 2/3 (2/3 of the block is pink).
the right block with 3 out of 4 strips marked in purple shows us 3/4 (3/4 of the block is purple).
it is essential for this method to orient the strips in one block to be at a right angle with the strips of the other block.
now, to do the multiplication you overlay the strips of both blocks.
you see this creates a chess board pattern. the total number of little squares or rectangles is the denominator (bottom part) of the result. in this case 12.
the number of little squares or rectangles that are in both original strips is the numerator (the top part) of the result. in this case 6.
so, yes, 2/3 × 3/4 = 6/12, which can then be refined to 1/2.
now, you have to do the same thing with the actual examples (I cannot draw here, sorry) :
1/4 × 3/5 = 3/20
the left block with 4 strips (one in pink, or whatever color you want), the right block with 5 strips (and 3 marked in e.g. purple).
and then the result block with 4 columns and 5 rows creating 20 little squares or rectangles, and 3 of them are in all original strips.
and the same
3/5 × 2/3 = 6/15 = 2/5
1/2 × 2/5 = 2/10 = 1/5

What is the solution for the equation 36³-26²-5 6³-2

Answers
Answer:
b = 0 and b = 4
Step-by-step explanation:
[tex]\frac{5}{3b^3-2b^2-5}[/tex] = [tex]\frac{2}{b^3-2}[/tex] ( cross- multiply )
2(3b³ - 2b² - 5) = 5(b³ - 2) ← distribute parenthesis on both sides
6b³ - 4b² - 10 = 5b³ - 10 ( subtract 5b³ from both sides )
b³ - 4b² - 10 = - 10 ( add 10 to both sides )
b³ - 4b² = 0 ← factor out b² from each term on the left side
b²(b - 4) = 0
equate each factor to zero and solve for b
b² = 0 ⇒ b = 0
b - 4 = 0 ⇒ b = 4

Answer:
x = [tex]\frac{1}{2}[/tex] , x = - [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
(2x - 1)(3x + 4) = 0
equate each factor to zero and solve for x
2x - 1 = 0 ( add 1 to both sides )
2x = 1 ( divide both sides by 2 )
x = [tex]\frac{1}{2}[/tex]
and
3x + 4 = 0 ( subtract 4 from both sides )
3x = - 4 ( divide both sides by 3 )
x = - [tex]\frac{4}{3}[/tex]

Answer:
[tex]\sf C. \quad \left(-\dfrac{13}{4},\dfrac{5}{2}\right)[/tex]
Step-by-step explanation:
The solution to a system of graphed equations is the point of intersection.
From inspection of the graph:
the x-coordinate of the point of intersection is -4 < x < -3the y-coordinate of the point of intersection is 2 < y < 3As the x-coordinate is negative, this eliminates answer options A and B.
Assessing the x-coordinate of answer options C and D:
⇒ C. -13/4 = -3.25
⇒ D. -5/2 = -2.5
Therefore, as the x-coordinate of the point of intersection is between -4 and -3, the approximate solution of the system of equations is:

Radius of the Circle (r) = 3cm
Length of the Arc (S) = 12cm
In any circle of radius r, the arc length S to the circumference equals the ratio of the angle θ subtended by the arc at the centre and the angle in one revolution. Thus, measuring the angles in radians, S=rθ.

Parallelogram ABCD is adjacent to rhombus DEFG, as shown below, and F C intersects A D at H. image If m ∠ B = 126 ° and m ∠ A H C = 142 ° , determine and state m ∠ G F H .
Answers
A quadrilateral in which opposite sides are parallel is called a parallelogram. The measure of the ∠GFH is 16°.
What is a parallelogram?A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
For a parallelogram and a rhombus opposite sides are parallel, therefore, the sides that are parallel are,
AB║DC║ED║FG
Since the sides are parallel,
∠ABC = ∠FGH = 126°
Also, ∠AHC and ∠GHF lie on the same line, therefore,
∠AHC + ∠GHF = 180°
∠GHF = 180° - 142° = 38°
Now, in ΔGHF
∠GHF + ∠HFG + ∠GFH = 180°
∠GFH = 180° - 126° - 38°
∠GFH = 16°
Hence, the measure of the ∠GFH is 16°.

x² + y² + Dx + Ey + F = 0 to x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0

Required: Find the values of h, k, and r using this formula
x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0
On comparing we get,
-2h = 42
h = 21
-2k = 38
k = 19
-47 = h² + k² - r²
-47 = 21² + 19² - r²
