Answer:
The smallest positive number is 8
Step-by-step explanation:
let the smallest positive number = x
45 is a multiple of 9 ⇒ 9 x 5 = 45
the next multiple of 9 after 55 is 63
= 9 x 7
= 63
Thus, x + 55 = 63
x = 63 - 55
x = 8
The greatest common factor of 45 and 63 = 9
Therefore, the smallest positive number is 8
First, find the number of inches
<span>1225 Miles = 77616000 Inches
then, move the decimal to until you have a ones place. </span>
<span>77616000. the decimal for this number moves to the left SEVEN places.
you end up with 7.7616000
</span>
it will look like this:
7.8 * 10^7
I rounded to the .8 because you didn't state how many significant figures, but it could easily be 7.76 * 10^7
the exponent above the 10 will tell you how many places to move. to get back to your original number, move it back to the right seven places. Of course, you would have to place hold the numbers with 0s. If it were negative, you would move the decimal the opposite way.
Answer:
<em>The third choice gives the correct sequence.</em>
Step-by-step explanation:
<u>The Number Line</u>
To represent numbers in the line, we use arrows starting from the mark for zero up to the given number. If the number is positive, the arrow points to the right and if the number is negative, the arrow points to the left.
The number -3 must be represented as an arrow to the left side of length 3. Subtracting something from the number should also point to the left side, but if the number is negative, then the new arrow points to the right side.
To subtract -1, the arrow should point to the right starting from -3
The third choice gives the correct sequence.
