Division is a simple operation in which a number is divided.  1.168 ÷ 8= 0.146, 2.246÷12= 0.1871, 3.4328÷4=0.8582, 4.729÷9=0.5254 and 5.8415÷5​​​​=1.168.

Division is a simple operation in which a number is divided.

Division lets us separate a number of objects into equal-size groups.

Division has 3 important parts dividend, divisor, remainder and quotient.

1.168 ÷ 8= 0.146

(Because 0.146*8=1.168)

2.246÷12= 0.1871

(Because 12*0.1871=2.246)

3.4328÷4=0.8582

(Because 4*0.8582=3.4328)

4.729÷9=0.5254

(Because 9*0.5254=4.729)

5.8415÷5​​​​=1.168.

(Because 5*1.168=5.8415)

Therefore 1.168 ÷ 8= 0.146, 2.246÷12= 0.1871, 3.4328÷4=0.8582, 4.729÷9=0.5254 and 5.8415÷5​​​​=1.168.

Step-by-step explanation:

The height of the window is 9-x feet, the perimeter of the window is 36-2x.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression.

Using letters or alphabets to represent numbers without giving their exact quantities is the idea behind algebraic expressions. The principles of algebra taught us how to express an unknown value using letters like x, y, and z. Here, we refer to these letters as variables.

Given that,

A window is 9 feet long.

Its length exceeds its height by x feet.

The length of the window = 9 feet

Then, the height of the window,

x feet shorter than the length= 9-x feet

As a result, the window is 9-x feet tall.

The perimeter of the window is 2 (l+b)

2 (9+9-x),

2 (18-x),

36 - 2x.

Therefore, the perimeter of the window is 36-2x.

Answer:

x² + (y – 3)² = 36  

and

x²+ (y + 8)²= 36  

Step-by-step explanation:

The equation of circle that has a center (a, b) is given by the formula

(x - a)² + (x - b)² = r²

where r is the radius of the circle

If the circle lies on the y axis, its x-coordinate must be 0.
The radius of the circle = 1/2 x diameter = 1/2 x 12 = 6 units

So the equation must be of the form
(x - 0)² + (y - b)² = 36

We can eliminate x² + (y – 5)² = 6
We can also eliminate (x + 6)² + y² = 144

That leaves us with the two possible equations

x² + (y – 3)² = 36   (center at 0, 3)

and

x²+ (y + 8)²= 36   (center at (0, -8) )

The total mass of the paper clips in scientific notation is 2.226*10 mg

We know that the mass of a single paper clip is:

M = 7.0*10⁻⁴ mg

And in one box has a total of 3.18*10⁴ clips inside of it, then the total mass of the paper clips on the box will be equal to the product between the mass of a single clip and the total number of clips.

We will get:

total mass = (7.0*10⁻⁴ mg)*(3.18*10⁴)

Using the associative property we can rewrite:

total mass = (7.0*3.18)*(10⁻⁴*10⁴) mg

                 = (22.26)*(10⁰) mg = 22.26 mg

Now we want to write this in scientific notation, so we need to have a single digit in the left of the decimal point, then we can rewrite this as:

It follows from the task content that the value of angle y is to be determined from the image attached to the task content.

On this note, one must recall that from polygon theorems; the sum of all exteriors angles of a polygon is equal to; 360°.

Therefore; we have;

60° + 70° + 65° + 40° + y° = 360°

By isolating y°; we have;

y° = 360° - 60° - 70° - 65° - 40°

The median class is 40 -60 as cf ≥ N/2

which is 33 ≥ 25

medain = 40 + |25-15|/18 ×20

medain = 40 + 200/18

median = 41.111

Mode = lower limit + f1-f0/2f1-f0-f2 × height

Here, f1 is the frequency of the modal class = 18.

f0 is the frequency of the preceding modal class = 9.

f2 is t/he frequency of the succeeding modal class = 13.
