Casey has 5/6 left of a section of sidewalk to clean. If he can clean 5/18 of a section in 1 minute, how long will it take him t

GaryK [48]

Answer:

Casey will take 3 minutes to clean $\frac{5}{6}$ part of the section.

Step-by-step explanation:

∵ Casey takes the time to cleans $\frac{5}{18}$ of a section = 1 minute

∴ He will take the time to clean complete section = $\frac{1}{\frac{5}{18} }$

= $1\times \frac{18}{5}$

= 3.6 minutes

Now time taken to clean $\frac{5}{6}$ part of the section = $\frac{5}{6}\times 3.6$

= 3 minutes

Therefore, left part of the section will be cleaned by Casey in 3 minutes.

vampirchik [111]

Answer:

a = -3 and b = 1

Step-by-step explanation:

x² - 6x + 10

→ Half the second term and place it in the bracket

( x - 3 )²

→ Square -3

- ( 3 )² = -9

→ Place this outside the brackets along with plus 10

( x - 3 ) ² - 9 + 10

→ Simplify

( x - 3 ) ² + 1
