Consider these three numbers written in scientific notation: 6.5 × 103, 5.5 × 105, and 1.1×103. which number is the greatest, and by how many times is it greater than the smallest number?

a. the greatest number is 5.5 × 105. it is 5 times greater than the smallest number.

b. the greatest number is 6.5 × 103. it is 50 times greater than the smallest number.

c. the greatest number is 5.5 × 105. it is 500 times greater than the smallest number.

d. the greatest number is 6.5 × 103. it is 5,000 times greater than the smallest number.

e. the greatest number is 5.5 × 105. it is 5,000 times greater than the smallest number.

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.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
