Math and Arithmetic

This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that in most cases you cannot convert between measures with different dimensions without additional information.

The Area could be a rectangle/ square, or other four sided figure.

However, assuming it is a square.

Then one side is sqrt(1521) = 39/ ft

Hence being a square to ther side is also '39' ft.

NB You need to be more specific as to the shape of the area.

[4] / [-1/2] =>

4/1 X -2/1 = -8/1 = -8 The answer!!!!!

Note the change of sign to (X) and the inversion of the denominator.

A "step" is not a very precise measurement; different people have steps of different lengths. However, a step is usually slightly less than a meter, so the answer will probably be: somewhat more than 1200 steps.

One very easy way to answer this is to see that 30 = 2 * 15. 2 = 200%. You can check this by seeing that 100% of 15 is 15, so twice that (200%) is 30.

The word "Hello" can be represented in binary using ASCII encoding. Each letter corresponds to a specific ASCII value that can be converted to binary. For example, "H" is 72 (binary 01001000), "e" is 101 (binary 01100101), "l" is 108 (binary 01101100), and "o" is 111 (binary 01101111). Therefore, "Hello" in binary is: 01001000 01100101 01101100 01101100 01101111.

There are 0.009km in 9 metres, however if the question is how many km are there in 9 miles then the answer is 14.5km (to 1 decimal place)

Remember

12 inches = 1 foot.

So in 247 inches there are 247/12 = 20 feet and 7 inches.

Acute ; < 90 degrees

Right Angles ; 90 degrees

Obtuse ; >90 degrees but < 180 degrees.

Straight line ; 180 degrees . An arc swept around a point on a straight line

Reflex ; The 'outside' angle to an acute or obtuse angle.

It is: 3*3*3 = 27

x - 4y = 4

Algebraically rearrange to

4y = x - 4

y = x/4 - 4/4

y = (1/4)x - 1

It is now in the form of y = mx + c

Where 'm' is the slope and 'c' is the y-intersect.

Hence the slope is ' 1/4' and y intersect is ' -1 '.

LCM of 20 and 49 is 980.

14 out of 6 simplifies to 7/3 by dividing both numbers by 2. As a mixed number, 7/3 = 2⅓.

To find the middle quantity, we first calculate the total sum of the five quantities using the average. The average of 5 quantities is 70, so their total sum is (5 \times 70 = 350). The known quantities are 50, 70, 60, and 80, which sum to (50 + 70 + 60 + 80 = 260). Therefore, the middle quantity is (350 - 260 = 90).

As a mixed number, 56 is the same as 1 55/1. When we convert it back into an improper fraction we get 1 x 1 = 1 + 55 = 56. Then we place it over the original denominator so 56/1.

109.5714

Both fractions have the same numerator (4), so the one with the smaller denominator is larger. Since 5 < 6, we have:

4/5 = 0.8

4/6 ≈ 0.667

So, 4/5 is greater than 4/6.

yees because if you divide everything by 8 to get y=7/8+3x/8 which is a linear function since it fits the equation y=mx+b

'Math(s)' is the shortened form of 'mathematics'. The word mathematics comes from Classical Greece, and means ' to learn '.

English is a communicative language. It has a structure known as 'Grammar'.

The word ' Grammar' again comes from Classical Greece, Because the Classical Greeks were the first civilisation to structure their language, into nouns, verbs, sentences etc.,

In England a school that is described as a Grammar School teaches Classical Greek, and Latin , and also teaches the structure of the English language. (A Greek/Grammar teaching School).

So if you learn Classical Greek and Latin at the most elementary level, you will learn lots of root words, and mathematical structure.

Unfortunately, many schools do not teach 'Classics'. and the world is poorer for it.

Many of the 'big' words, in science have their roots in Classics.

e.g.

Trigonometry(Trig) ; measuring trigons/triangles.

Chlorine ; The colour 'Green' (gas)

The word 'mathematics' comes from Classical Greek word . matema' , meaning 'to learn'.

Its correct modern English is Mathematics. often shortened to 'maths'.
