9)5.00000...... = 0.555555...... The answer ( recurs to infinity).

The Diameter is the distance from one side of the circle all the way to the other side.

The Radius is half the distance in a circle.

Simply put: 40cm = Diameter

20cm = Radius (Half the distance) :)

6/11 - 1/2 =

12/22 - 11/22

1/22 The answer!!!!!

Here is a little table for multipliction/division.

• X + = +

• X - = -

• X + = -

= X - = +

NB If no sign is shown , read it as plus (+).

y = x - 4

x^(2) + y^(2) = 8

Hence

y^(2) = 8 - x^(2)

Square up the linear eq'n and substitute

Hence

y^(2) = ( x - 4)^(2)

NB Notice the RHS is wholly squared , not individual terms.

Substitute ; this eliminates 'y'

( x - 4)^(2) = 8 - x^(2)

Square out the brackets

x^(2) - 8x + 16 = 8 - x^(2)

Collect terms

2x^(2) -8x +8 = 0

Factor

2(x^(2) - 4x + 4) = 0

(x- 2)(x - 2) = 0

Hence x = 2 ( The 'x' coordinate) .

Substitute into either eq;n for 'y'

y = 2 - 4

y = -2

Hence

( x,y) = ( 2,-2) ; The point of contact of the tangent and the curve.

-2

You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.

A minimum of two points is required to draw a straight line. Any two distinct points can be connected by a straight line, and this line will extend infinitely in both directions. Additional points can lie on the same line, but only two are necessary to define the line's direction and position.

20,000/70 = 285.71428571428571428571428571429

In the number  compare the values of the digits 6 and 7.

How much more is the digit 6?

2 miles + 327 yards = 2*5280 + 327*3 = 10560 + 981 = 11541 feet

Y Axis - Forward and Backward

X Axis - Left and Right

Z Axis - Physical UP and Down

Science can be found in many aspects of life on earth. Social science is one of them.

Social science has everything to do with integration in all walks of life. It helps people to be more efficient on daily bases. = Socialization.

It usually starts with our upbringing at home and continues at school, then in work places and so forth....

The word SCIENCE means: Organized knowledge.

That organized knowledge is long described in the Bible, given right from the beginning of mankind by its Creator. The Bible is a library of 66 Books, which is the letter from the Most High.

It contains laws of the cycle of water,

Read Ecclesiastes 1: 7; Psalms 104: 10-14.

The shape of our planet.

Read Isaiah 40: 22; Job 26: 7 which shows that planet Earth is a circle that is hanging upon nothing. That fact was aware of, since the eighth centery B.C.E.

Hygene laws.

Read Numbers 19:11-22 ; Deuteronomy 23: 13.

Throughout the centuries there have been great ignorance on matters of health. In the past century, doctors did not always wash after touching the dead, causing other deaths.

One Biologist said, That innovators we think we are; we're marely the repeaters."

Social science or ( integration rules) can be found in the Book of Galatians 5: 22,23 called the fruitage of the spirit of God, in these words.

"Which is love, joy, peace, patience, kindness, goodness, faith, mildness, self-control. Against such things there is no law.

So to answer your question, social science is the organized knowledge of human behaviour, that has long been given be Jehovah God. And as the biologist said: "Humans have not invented anything".

Our lack of knowledge comes from our lack of wisdom, to turn to the Most High, our Creator, who has our best interest.

Read Jeremiah 10: 23; Isaiah 48: 17,18; 2 Timothy 3: 16,17

EVEN!!!!!

Any number that ends is 0,2,4,6,8 is EVEN

Any number that ends in 1,3,5,7,9 is ODD .

Since 70 ends in '0' , then it is even.

Similarly, 70,000,000 is even , but 70,000,003 is ODD.

112 X 7 = 784

0.025 as a decimal is in its simplest form .

However,

0.025/1.000 = 25/1000 = 1/40 as a fraction in its simplest form .

4x + 2y = 12

Rearrange into straight line equation ( y = mx + c)

Where 'm' is the slope/gradient.

Hence

2y = -4x + 12

y = -2x + 6

Hence '-2' is the gradient /slope.

f(x) = 4x + 12

Let 'y' = f(x)

Hence

y = 4x + 12

y - 12 = 4x

x = ( y - 12) / 4

'Swop the letters'

y = ( x - 12) / 4

Hence f'(x) = ( x -12) / 4

The inverse function.

It depends on the persons length of stride.

Assuming one step is 3feet = 1 yard, then 1 mile = 1760 yards, or 1760 steps.

-x -2 = 1 - 2x

Add 'x' to both sides ( preserve equality ; balance)

-2 = 1 - x

Add '2' to both sides

0 = 3 -x

Add 'x' to both sides

x = 3 The Answer !!!!!

NB When said as 'adding/subtracting etc., to both sides', this is to preserve equality (=), so the eq'n remains 'balanced', just like a weigh scales.

e.g. with numbers.

5 = 3 + 2 , however, 5 - 2 = 3 ( same difference!!!!!).

3.5 million is written in numeral as 3,500,000. This is done by placing a comma every three digits, starting from the right of the number. Thus, 3.5 million equals three million five hundred thousand.

Number ; 300,000,000

Words ; three hundred million.
