Math and Arithmetic

The number 9000000000000000000000000000 is called nine octillion in the short scale naming system. In the long scale naming system, it is called nine quadrillion. The short scale system is commonly used in the United States and most English-speaking countries, while the long scale system is used in some European countries.

To add one third and one seventh, we need to find a common denominator. The least common multiple of 3 and 7 is 21. So, we can rewrite one third as 7/21 and one seventh as 3/21. Adding these fractions together, we get 7/21 + 3/21 = 10/21. Therefore, one third plus one seventh is 10/21.

Convierte 3.5 km a millas

If you divide a speed in miles per hour by 60, you convert that speed into miles per minute. For example, if a speed is 120 miles per hour, dividing by 60 gives you 2 miles per minute. This conversion illustrates how many miles are traveled in one minute at that speed.

To determine the time a half hour from now, simply add 30 minutes to the current time. For example, if it is currently 2:00 PM, it will be 2:30 PM in half an hour. If you provide the current time, I can give you the exact time a half hour from now.

18

Remember

6 x 3 = 18

9 x 2 = 18

180 degrees.

V= number of vertices

E= number of edges

F= number of faces

For ALL convex polyhedra V-E+F=2

(Euler Characteristic of closed convex polyhera is 2; the genus is 2-2=1)

For a torus (donut shape) V-E+F = 3 (genus is 3-2= 1)

To find half of a number, you simply divide the number by 2. In this case, to find half of 524, you would divide 524 by 2. The result of this division would be 262. Therefore, half of 524 is 262.

Let the numbers be 'm' & 'n'

Hence

m + n = -29

mn = 54

Algebraically rearrange the first first eq'n, and then substitute into the second equation.

m = -29 - n

n(-29 - n) = 54

-29n - n^(2) = 54

Equatimg to zero.

It is now in Quadratcic Form

n^(2) + 29n + 54 = 0

Factor

( n + 2)(n + 27) = 0

Hence

n = -2

&

n = -27

Are the two numbers. !!!!!

54 = 47 + 7

84 = 79 + 5

NB 5,7,47,79 are all prime numbers.

Let the unkniwn number be 'x'

Hence

54 + x = 112

Subtract '54' from both sides.

54 - 54 + x = 112 - 54

x = 112 - 54

x = 58 The answer!!!!!

The answer to 58 plus 112 is 170. This is because addition is a basic arithmetic operation where two or more numbers are combined to give a total sum. In this case, adding 58 and 112 together results in a sum of 170.

'Equivalent'. Fractions.

e/g/

1/2 = 2/4

NB The three hosizontal lines means ' equivalent to'.

0.75 = 3/4 4

Method.

0.75/1.00

Cancel down the decimal point

Hence

075/100

Drop the prefix zero

Hence

75/100

Cancel down by '25'

75/100 = 3/4

It's 380 km long.

In terms of miles it is about 250 miles.

Remember 1000 m = 1 km

So 380 m = 0.380 km or just 0.38 km .

Exactly 36 times
