Malala is following this recipe for bread rolls. She uses 400 ml of water. How much of each of the other ingredients does she uses? Recipe: Makes 15 bread rolls 480 g flour 12 g salt 18 g yeast 30 ml oil 600 ml water

320 g flour

8 g salt

12 g yeast

20 ml oil

Step-by-step explanation:

To get from 600 to 400, divide by 1.5

To find the amounts of the other ingredients she will use, divide by 1.5

480/1.5 = 320 g flour

12/1.5 = 8 g salt

18/1.5 = 12 g yeast

30/1.5 = 20 ml oil

x = 12

y = 15

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
