How do you divide two numbers that are in scientific notation?
For example, (4.1076 x 10^3)/(2.8 x 10^4) = (4.1076/2.8) x [10 ^(3 - 4)] = 1.467 x 10^-1 or (4.1076 x 10^3)/(2.8 x 10^-4) = (4.1076/2.8) x [10 ^(3 - -4)] = 1.467 x 10^7
Two numbers have a sum of 40 the difference is 10 what are the two numbers?
2 Numbers are a and b. We have( a>b) a+b=40(1) and a-b=10(2) a=10+b( from 2. Subtracts both side by b) => 10+b+b=40 (from 1. Substitute a with 10+b) => 10+2b =40 => 2b =30 => b =15 =>a=10+15=25 => a=25 b=15.
What is B squared minus 100?
It is: (B -10)(B +10) when factored
What does b equal in 2b minus b minus 10 equals negative 13?
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
How do you divide using scientific notation?
When dividing a smaller number into a larger number, subtract the exponents. 8 x 10^5 divided by 4 x 10^2 = 2 x 10^3
Can this be true b - b?
Yes because it is possible to have 10-10 or 6-6, so why not b-b?
What is the value of a plus b equals -7 and b equals 10?
We are given that a + b = -7 and b = 10 Therefore a +10 = =7 Subtract 10 from each side So a + 10 - 10 = -7 + 10 Which simplifiesn to a = 10 - 7 So a = 3
What is the value of a-b if a equals10 and equals - 5?
5
What is the factor of 2b - b - 10?
-8
What is the value of a - b if a equals 10 and b equals 5?
a( 10 ) - b( 5 ) = 5 ?
What is b. b over 5 plus b over 3 equals 10?
If: b/5+b/3 = 10 then b works out as 18.75
How do you write a program in C to swap two variables without using the third one - 46k?
int a = 5; int b = 10; a = a + b; // a = 5 + 10 = 15 b = a - b; // b = 15 - 10 = 5 a = a - b; // a = 15 - 5 = 10
