What is the answer in 2 x 5 x 10 - 1?
2 x 5 x 10 - 1= n 10 x 10 - 1=n 100 - 1 =n 99= n
What does N equal in N times 10 to the 9th power equals 6787000?
6787000 = 6.787 x 10^6, so for N x 10^9 = 6.787 x 10^6, divide both sides by 10^9, and N = 6.787 x 10^-3 = 0.006787
How do you solve for x in 5x plus y plus 10?
Let 5x + y + 10 = N Then 5x = N - y - 10 x = (N - y - 10) ÷ 5. Obtain the values for N and y. Substitution in the equation above will enable a value for x to be calculated.
How does a number in scientific notation change when you multiply it by 100?
If number is a x 10^n it then becomes a x 10^(n + 2)
What is the value of n in 10 x n equals 0.27?
n=0.027
What is 10 x n 0.06 then what is n?
10 x n = 0.06 /10 /10 n = 0.006
What is the answer in 2 x 5 x 10 - 1?
2 x 5 x 10 - 1= n 10 x 10 - 1=n 100 - 1 =n 99= n
What does N equal in N times 10 to the 9th power equals 6787000?
6787000 = 6.787 x 10^6, so for N x 10^9 = 6.787 x 10^6, divide both sides by 10^9, and N = 6.787 x 10^-3 = 0.006787

How do you find all the combinations of a list?
To find the number of combinations possible for a set of objects, we need to use factorials (a shorthand way of writing n x n-1 x n-2 x ... x 1 e.g. 4! = 4 x 3 x 2 x 1). If you have a set of objects and you want to know how many different ways they can be lined up, simply find n!, the factorial of n where n is the number of objects. If there is a limit to the number of objects used, then find n!/(n-a)!, where n is the number of objects and n-a is n minus the number of objects you can use. For example, we have 10 objects but can only use 4 of them; in formula this looks like 10!/(10-4)! = 10!/6!. 10! is 10 x 9 x 8 x ... x 1 and 6! is 6 x 5 x ... x 1. This means that if we were to write out the factorials in full we would see that the 6! is cancelled out by part of the 10!, leaving just 10 x 9 x 8 x 7, which equals 5040 i.e. the number of combinations possible using only 4 objects from a set of 10.
How do you solve for x in 5x plus y plus 10?
Let 5x + y + 10 = N Then 5x = N - y - 10 x = (N - y - 10) ÷ 5. Obtain the values for N and y. Substitution in the equation above will enable a value for x to be calculated.
What is the value of log 1?
log 1 = 0 if log of base 10 of a number, N, is X logN = X means 10 to the X power = N 10^x = 1 x = 0 since 10^0 = 1
How does a number in scientific notation change when you multiply it by 100?
If number is a x 10^n it then becomes a x 10^(n + 2)
What is the value of n in 10 x n equals 0.27?
n=0.027
Difference of 10 and a number?
10 - x
How many combinations of 8 numbers are possible from 10 numbers?
In general, the number of combinations of n things taken r at a time isnCr = n!/[(n - r)!r!]Thus, we have:10C8= 10!/[(10 - 8)!8!]= 10!/(2!!8!)= (10 x 9 x 8!)/(8! x 2 x 1)= (10 x 9)/2= 5 x 9= 45
