Tiana has already plepared 6 kilograms of dough and will continue preparing 1 kilogram of dough every hour. How many hours did Tiana work if she prepared 15 kilograms of dough?

9 hours

Step-by-step explanation:

6 kilos done - 15 total kilos = 9 to do

1 kilo/1 hour is the rate so 9 kilos/9 hours

9 hours in total

if not this is actually a trick question because it asked how many hours which then would mean 15 hours because the rate is 1 kilo/1 hour

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
