PLEASE HELP ASAP!!! <333

1. .85

10 to the first power is still 10 so 8.5/10 = .85

2. 2.4892

10 to the second power is 100 so move decimal left 2 spaces

3. .00128

10 to the thrid power is 1,000 so move decimal left 3 places

4. .80734

same as last

5. .041595

10 to the fourth is 10,000 so move decimal left 4

6. .000528

10 to the fifth is 100,000 so move decimal left 5

do 7&8 on your own

9. 12,000,000

the power is 9 so move decimal right 9 spaces

899.2

same thing move decimal right 2

so >

10. 46,020

move dec. right 4

70,000

move dec. right 4

so <

do 11 on your own

for 12-17 try to keep max 2 numbers to the right of the decimal is there are 3 or more numbers (other than zero) otherwise just one to the right

12. 42 x 10^3

since we removed three zeros to the left of the decimal we multiply by 10^3

13. 3.4 / 10^3

since we moved the decimal right 3 we divide 3.4 by 10^3 to get our original number.

do 14-17 on your own

Sorry I don't have time to help with 18-23 but I wish you the best of luck and have a great day!

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
