0.00037 = 3.7×10^-4
37,000 = 3.7×10^4
_____
The exponent of 10 is the place-value multiplier that the most-significant digit has.
In the first number, the most-significant digit (3) is multiplied by 0.0001 to find its place value. Of course 0.0001 = 10^-4.
In the second number, the most significant digit (3) is multiplied by 10,000 to find its place value. You know that 10,000 = 10^4.
Multiply each number by 4
1*4= 4
4*4=16
16*4= 64
64*4= 256
256*4= 1024
Answer: 4
The fraction is 1/3. on the input side, it’s going up by one, (6,7,8 etc) and on the output side it’s going up by 3. (18+3=21). if u were to double check 6/18 reduces to 1/3! so the answer is 1/3
1. 9.355 ×
can be used to express the age of the dinosaur fossil.
Step-by-step explanation:
Step 1; To determine which value is the closest to 93,550,000 we must calculate how much the 4 options equal. If there are decimals in the number, they are moved from the decimal part of the number to the integer part with every power of 10 i.e. 2.4 × 10 = 24, 2.44 × 10² = 244.
Step 2; Now we determine how much the 4 options equal.
1. 9.355 ×
= 93,550,000.
2. 9 ×
= 90,000,000.
3. 9.36 ×
= 93,600,000.
4. 9.3 ×
= 93,000,000.
Out of the four options, option 1 equals the value of 93,550,000. So option 1 can be used to express the age with the highest precision.
