Math and Arithmetic

tank good ness

aswome joke got from friends

ttyl

There are plenty of websites but not all of them are children friendly or virus proof but the one that is fine is bitesize or revise wise and then you just add your keystage( ks1, ks2 or ks3)

you add exponents in a case like 1 to the 5th (to the 5th is your exponent of 5)

So 1 to the 5th + 1 to the 9th. you would just add your exponents. so 9+1=10

so you answer would be 1 to the 10th.

this is only when you have 2 of the same base number, in this case, your base number is 1

'24' is a multiple of '4' ( 4 x 6 = 24)

However, '4' is a factor of '24'.

84

6^(2) X 5^(2) =

36 X 25 =

900

This is subtraction of fractions.

Hence

9/16 - 9/20 =>

[9(20) - 9(16)] / (16 x 20)

[180 - 144] / 320

[36] /320

Cancel down by '4'

9/80 The answer ; this will not reduce any further.

It is 17400.

You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.

1400

1350 ? Look at the 'tens' number, '5' in this case. If '5' or greaterm then add '1' to the 'hundreds' number.

1349 is nearer 1300

but

1350 is nearer 1400

NB THis applies to any numbers. Given a million, you inspect the 'hundred thousand' number. or 'tens' inspect the 'units' number.

The number 256000 in Scientific Notation is: 2.56 × 105

I am assuming yo mean square feet.
There are 9 square feet in a square yard, 3 feet by 3 feet.
150 times 9= 1350 square feet

YES!!!

3/6 = 1/2

NB THree '3' is a common factor of both '3' and '6' , so you cancel down*reduce) by dividing both numbers by '3'

NB You can do this proceedure with any fractions

e.g. 9 /27 = 1/3

16/20 = 4/5

et seq/.

No such thing as a 'hepagon'. I think you mean 'HEPTAGON'. Note the spelling.

A heptagon is a seven(7) sided 2-dimensional figure.

From their Latin roots, the names of polygons are : -

3 ' Trigon (Triangle).

4 ' Tetragon ( Quadrilateral)

5 ' Pentagon

6 ' Hexagon

7' Heptagon ( as given)

8 ' Octagon

9 ' Nonagon

10 ' Decagon

100 ' Centagon

1000 ' Millagon.

'--gon' is also Latin , for '2 dimensional figure.

So learn some Latin. Science and Maths use a lot of words from these ancient languages.

The smaller number is x. The larger number is 4x + 4. Their sum is 34.

Therefore x + 4x + 4 = 34. 5x + 4 = 34. 5x = 30. x = 6.

The smaller number is 6.

The larger number is (4 x 6) + 4 = 28.

180

We note that there are a difference of '9' between terms . Hence '9n'

Next find the constant 'c'

1st term ; 9(1) + c = 20 => c = 11

2 nd term ; 9(2) + c = 29 => c = 11

nth term is 9n + 11

e.g.

7th term is 9(7) + 11 = 63 + 11 = 74

8 X x = 24

Divide both sides by '8'

x = 24/8 = 3

'3' is the answer!!!!!

YES!!!

6 billion is 6,000,000,000 = 6.0 x 10^(9)

6000 million is 6,000,000,000 = 6.0 x 10^(9)

To compare decimals, bring the decimals to the same number of decimal places, by inserting suffix 'zeroes'. Three decimal places in this case.

0.011 ^ 0.01

Hence

0.011 & 0.010

Drop the decimal point

0011 & 0010

Drop the prefix zeroes

11 & 10

I think you will agree that 11 is greater than 10 ( 11 > 10)

Hence it follows that

0.011 > 0,01

NB THis method is good for comparing all decimals to 'n' number of places.

You spell ' equaiateral;, correct;y as 'equilateral'.

A SCALENE triangle cannot be EQUILATERAL, because for all scalene triangles , the length of the three sides are all different and the angles are all different values.

An EQUILATERAL triangles has its three sides of equal length , and its three angles all at 60 degrees.

There are four 2-digit prime numbers that have 4 as one of their digits: 41, 43, 47, and 49. However, 49 is not a prime number because it is divisible by 7. So, the correct answer is three 2-digit prime numbers with 4 as one of their digits.

Well, isn't that a happy little math question? To find 80 percent of 35, you simply multiply 35 by 0.80. So, 35 x 0.80 equals 28. So, 80 percent of 35 is 28. Just like painting a beautiful landscape, math can be a peaceful and rewarding experience.

2 x 60 = 120

Well, isn't that just a happy little question! If you are 78 years old, you were born in 1943. Just imagine all the beautiful landscapes and happy little trees you've seen in your lifetime. Remember, every year is a new opportunity to paint a masterpiece on the canvas of your life.
