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.

Answer:
the number of pounds that should be mixed is 30 pounds
Step-by-step explanation:
The computation of the number of pounds that must be mixed is shown below:
Let us assume the number of pounds be x
Now the equation is
(x) (1) + (15) (1.60) = (x + 15) (1.20)
x + 24 = 1.20x + 18
24 - 18 = 1.20x - x
6 = 0.20x
x = 30 pounds
Hence, the number of pounds that should be mixed is 30 pounds
