Answer:
Megan is not correct
Step-by-step explanation:
Since it takes 20 minutes to cook per kg, a total of 5.4kg will take 20 * 5.4 minutes to cook = 108 minutes to cook
Now, to cook for another 90 minutes. Time now is thus 90 + 108 = 198 minutes
Again, she is to leave for 30 minutes
So therefore, total time spent in cooking the chicken = 198 minutes + 30 minutes = 228 minutes
So the difference in time between 2:30 pm and 6pm is 3 hrs : 30 minutes
There are 60 minutes in an hour , so total amount of minutes is 3(60) + 30 = 180 + 30 = 210 minutes
What we calculated in minutes is more than what Megan says the cooking will take. So Megan isn’t correct
Answer:
true
Step-by-step explanation:
Answer: 16
Step-by-step explanation:
The constant of proportionality is a ratio that exist between two directly proportional quantities. From the question, recipe says to use 1.5 cups of flour to make 24 cookies.
y = the number of cookies made
x = the number of cups of flour used
y = kx
k = y/x
k = 24/1.5
k = 16
Therefore, the constant of proportionality which relates the number of cookies made, y, to number of cups of flour used, x is 16.
