Answer:

Area of the sector = 27 pi square inches

Step-by-step explanation:

Given that the clock is having a radius of 9 inches and the time shown is 4:

The clock has 12 hours shown from 1 to 12. When it is showing time as 4 then angle covered by the radii (i.e. big and small hands) would be 4/12 times 360

=120 degrees

Hence area of sector

= central angle x area of circle/360 degrees

=120(9x9xpi)/360

=27 pi square inches

Area of the sector = 27 pi square inches

Kim is reading a book with 380 pages. She read 20 pages each day until she reached Part 2 of the book. Part 2 of the book is 160

If you divide 380 by 20, you get 19. To check this, multiply 20 x 19 to see 380. Hope this helps :D

Bob and Maria each purchase steak from the butcher. Maria selects a cut that costs $19.98 per pound. Bob’s selection costs $13.9

Sidana [21]

Answer:

Bob is paying more for the actual steak

Step-by-step explanation:

we know that

Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)

Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)

Bob's cut is 2/3 all meat

Find the unit rate of Bob's cut for all meat

$\frac{13.98}{(2/3)} \frac{\$}{pounds} =20.97\frac{\$}{pounds}$

therefore

$\$20.97> \$19.98$

Bob is paying more for the actual steak

If a divides c and that b divides c. Prove ab divides c

Lera25 [3.4K]

If a divides c,

then 'a' is a factor of 'c'.

Also,

If 'b' divides c,

then 'b' is also a factor of 'c'

therefore,

'a' and 'b' are factors of 'c'

Hence, a and b divides 'c'

so, c = a*b

and ab will also divide c.

Hence, proved.
