Answer:
B. 1.47*10^18
Step-by-step explanation:
Given
Distance of largest start from earth in light years = 250000
1 light year = 5880000000000 miles
So,
Distance of largest star from earth in miles = 250000 * 5880000000000
= 1470000000000000000 miles
In order to convert in scientific notation, point will be moved 18 places to the left, so the number will become:
1.47* 10^18 miles
So option B is correct..
Answer:
1. 7
2. 1.25, 5/4, 1 1/4
3. -0.7
4. 20
5. 4.8
6. 30
7. 1.4
8. 28
9. -3.3 (the last 3 is infinite)

9 dollars represents 90% of the cost. Divide 9 by 0.90 to get the original price, 10 dollars
The word "similar" from a math standpoint means to express proportionality. So long as two shapes have proportional sides, the exact lengths do not have to be equal. However, the angles need to be the same.
