6 minutes because 6 x 2 is 12.
I would split 64 into 60 & 4, and 43 into 40 & 3
Than i would add the 60 and 40 together (which will give me 100)
I will than add 4 & 3 together (which will give me 7)
Than i will add 100 and 7 together, which will give me 107
107 is your final answer
hope this helps

Answer:: D(t)= 50(4/5)^t
Step-by-step explanation: If 1/5 of the temperature difference is lost each minute, that means 4/5 of the difference remains each minute. So each minute, the temperature difference is multiplied by a factor of 4/5 (or 0.8).
If we start with the initial temperature difference, 50° Celsius, and keep multiplying by 4/5, this function gives us the temperature difference t minutes after the cake was put in the cooler.
Answer:
C = 28.26 cm
Step-by-step explanation:
The figure shows a circle of diameter 9 inches.
The person has taken radius r as 9 inches which is wrong.
The radius must be (9/2) = 4.5 inches, such that,
Circumference = 2πr
= 2×3.14×4.5
= 28.26 cm
Hence, this is the required solution.
