Tom has 39 silver dollars. You can do this on your head. Jimmy has 32, and Tom 39.
If you have 12 dollars and you buy 3 paper back books, they each cost the same amount. So you would divide 12 dollars among 3 books to get the same answer for all of them. 12 divided by 3 equals the answer.
Then if you have 28 dollars and you buy 7 paper back books, they all cost the same amount. So that would be 28 divided by 7, equals the same answer.
2 is a multiple of 4, so anything that's a multiple of 4 will automatically be a multiple of 2
so 3 x 4 = 12
so multiples of 12 that are between 67 and 113 are...?
12 x 6 = 72
12 x 7 = 84
12 x 8 = 96
12 x 9 = 108 <span> 72 or 84 or96 or 108
all are divisible by 2,3 and 4
all fall between 67 and 112</span>
Answer:
<h2>
<em>1×10⁻⁴ and 9.8×10⁵</em></h2>
Step-by-step explanation:
The standard form of writing a scientific notation is expressed as
where a, b and n are integers. Note that a, b and n cannot be a fraction. When writing in scientific notation, the value of 'a' must not be equal to zero and it must not be a 'two digits values' but just 'a digit value'.
<em>Based on the above conclusion, the following numbers are correctly written in scientific notation.</em>
<em>1×10⁻⁴ and 9.8×10⁵</em>
- The expression 10.8×10 −3 is not correctly written because the value of a on comparison is a two digits number i.e 10.
- Also, 0.54×10^6 is not correctly written because a is zero on comparison
- 7.6×10 2.5 is not correctly written because the power is a decimal number i.e 2.5. We must only have an integer as the degree.
