Answer:
2.5 * 10^-5 cm
Step-by-step explanation:
Scientists know that the diameter of a normal cell is 0.000025 cm. How is that number written in scientific notation? please help
Given that:
Diameter of a Normal cell = 0.000025 cm
In standard form:
Count the spaces in between each digit from right to left until the point where the decimal point is located.
The number of spaces in between each digit = 6
Since the spaces are counted backwards, the power notation takes a negative (-) sign.
0.000025 is thus rewritten as :
0.000025 = 25 * 10^-6
To place a decimal point in between 25 and rewrite as 2.5,
We the write as :
2.5 * 10^-5 cm
Answer:
7000 (7 thousand)
700 (7 hundred)
20 (2 tens)
2 (2 units)
Step-by-step explanation:
what is the relationship between the values of the given digits?
1. The 7s in 7,700
2. The 2's in 522
From the knowledge of place values;
7,700 could be broken down thus :
7000 + 700 + 0 + 0
The first 7 depicts thousands as it has 3 trailing digits (7000)
The second 7 depicts hundred as it has 2 trailing digits (700)
522 could be broken down thus :
500 + 20 + 2
From 522
The first '2' has one trailing digit = tens
The ending / last digit ia always = Unit value
Point form: (-3,6)
Equation form: x=-3, y=6
