Consider these three numbers written in scientific notation: 6.5 × 103, 5.5 × 105, and 1.1×103. Which number is the greatest, an
2 answers:
Answer:
Option C. is the answer.
Step-by-step explanation:
There are three terms written in scientific notation
6.5 × 10³, 5.5 × and 1.1 × 10³
Now we can rewrite the numbers as
6,500, 550,000 and 1,100
Greatest number is 550,000 and smallest number is 1,100
and the ratio of greatest and smallest numbers is = 500
Therefore, greatest number 5.5 × is 500 times of the smallest number.
Option C. is the answer.

Given : Two inequality is given to us . The inequality is v + 8 ≤ -4 and v - 6 ≥ 10 .
To Find : To write those two inequality as a compound inequality with integers .
Solution: First inequality given to us is v + 8 ≤ -4 . So let's simplify it ;
⇒ v + 8 ≤ -4 .
⇒ v ≤ -4 - 8.
⇒ v ≤ -12 .
Now , on simplifying the second inequality ,
⇒ v - 6 ≥ 10 .
⇒ v ≥ 10 + 6.
⇒ v ≥ 16 .
Hence the required answer will be :
First one implies that v is less than or equal to -12 whereas the second one implies that v is greater than or equal to 16 .
