Answer:
Step-by-step explanation:
Let's take 4200 as an example.
To convert 4200 into scientific notation, follow these steps:
- Move the decimal 3 times to left in the number so that the resulting number, m = 4.2, is greater than or equal to 1 but less than 10
- Since we moved the decimal to the left the exponent n is positive
n = 3
- Write in the scientific notation form, m × 10^n
= 4.2 × 10^3
Therefore, the decimal number 4200 written in scientific notation is 4.2 × 10^3 and it has 2 significant figures.
To test whether it's a factor:
-- Divide the big number by it. 81 / 6 = 13.5 .
-- If the quotient is a whole number,
then the small number is a factor
of the big number. 13.5 is not a whole number.
-- If the quotient is not a whole number,
then the small number is NOT a factor
of the big number. 6 is NOT a factor of 81 .
Answer:
154 Minutes
Step-by-step explanation:
So first we know that:
28 divided by 14 is:
2
Next Multiply 77 by 2:
154 Minutes
Hence, the correct answer is 154 Minutes
Answer:
x > -3/7
Step-by-step explanation:
Eliminate parentheses, collect terms, and subtract the constant on the left.
5(3 -x) -4(2 -3x) > 4
15 -5x -8 +12x > 4
7x +7 > 4
7x > -3
x > -3/7 . . . . . divide by the coefficient of x
