The total area of the shaded regions in fraction of the total area of the block is 3/8 as the common fraction.

A common fraction, sometimes known as a common fraction, is a fraction with an integer numerator and denominator. A common fraction may be used to identify a portion of a larger whole or set.

Multiply each component of a fraction by both the denominator of another fraction to find the common denominator. To calculate the common denominator of 1/3 + 2/5, multiply the 1 through 3 by 5 and the 2 and 5 by 3. You should obtain a total of 5/15 + 6/15. The fractions can then be calculated.

Let's divide each square across four equal sections, for a total of 16 sections..

Using symmetry, one of the four portions in the top left square is shaded, and the same is true for the bottom right square.

Furthermore, two of the four squares inside this top right and bottom left corners are darkened.

Consequently,

the shaded area is:

{1 + 1 + 2 + 2}/ 16

6 /16 =  3 / 8

Step-by-step explanation:

960/40 =

To make it simpler you could divide 10 by both digits to simplify them (as in fractions).

960/10 = 96

The volume of the rectangular prism is 243 cm³

given that

The top face of the cube has an area of 9 cm²

since All the faces of the cube are squares

therefore The top face is a square

∵ Area of any square = L² , where L is the length of the side of

 the square

∵ Area of the top face is 9 cm²

∴ L² = 9 ⇒ take √ for both sides

∴ L = 3 cm

∵ The volume of any cube = L³

∵ L = 3 cm

∴ The volume of the cube = (3)³ = 27 cm³

- We will use 9 cubes to make a rectangle prism

∴ The volume of the rectangle prism is equal to the volume of

 the 9 cubes

∴ The volume of the prism = 9 × volume of a cube

∵ The volume of the cube is 27 cm³

∴ The volume of the prism = 9 × 27 = 243 cm³

* The volume of the rectangular prism is 243 cm³

The equation of the lines in slope intercept form and standard form is y = -2x + 10 and 2y+3x = 10

The equation of a line in point slope form is y = mx + b.

Given the equation below:

y-7 =-5/2(x+4)

2(y-7) = -5(x+4)

2y-14 = -4x - 20

2y = -4x-20+40

2y = -4x + 20

y = -2x + 10

For the equation;

y = -3/2 x + 5

Multiply through by 2

2y = -3x + 2(5)

2y = -3x + 10

Martha's claim that the 25% of the learners are girls, is correct.

In this question,

There are 900 boys and 300 girls at Eqinisweni secondary school.

Martha claims that 25% of the learners are girls.

We need to verify her claim by means of calculations.

300 / (900 + 300)

We simplify above expression.

= 300 / 1200

= 1/4               ..................(Cross out the common factor)

Now multiply a number 25 to both the numerator and the denominator:

The bacterial cell is about 7 × 10^(1) times smaller than the amoeba cell in scientific notations.

What are scientific notations?

Scientific notations are a way of representing either a very small or a very large number in the powers of 10. Scientific notations comprise digits from 1 to 9 with powers of 10.

Calculation of the amount by which a bacterial cell is smaller than the amoeba cell

Given the length of amoeba cell in scientific notations is 3.5 × 10^(- 4)

The length of a bacterial cell in scientific notations is 5 × 10^(- 6)

To obtain how small the bacterial cell is from the amoeba cell, we need to divide both the lengths i.e.

= 3.5 × 10^(- 4) / 5 × 10^(- 6)

= 0.7 × 10^(2)

= 7 × 10^(1)

Hence, the bacterial cell is about 7 × 10^(1) times smaller than the amoeba cell in scientific notations.

In insights, the standard deviation is a proportion of how much variety or scattering of a bunch of values. A low standard deviation shows that the qualities will generally be near the mean of the set, while an elevated expectation deviation demonstrates that the qualities are fanned out over a more extensive territory. The standard deviation can generally be determined considerably more effectively with a number cruncher, and this might be satisfactory in certain tests. On my adding machine, you go into the standard deviation mode. Consequently, the main distinction among change and standard deviation is the units. For instance, in the event that we took the hours of 50 individuals running a 100-meter race, we would catch their time like a flash. Standard deviation assumes a vital part in the realm of money. In finance standard deviation is a factual estimation, when it's applied to the yearly pace of return of a venture.
