sponge cake=0.3
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}
Answer:
It will take a total of 2.73 hours if they worked together
Step-by-step explanation:
Here, we are seeking to calculate the joint rate.
Let the amount of work to be done is say x
Seth’s rate will be x/6 , while violet’s rate will be x/5
Their joint rate will be ;
x/6 + x/5 = 11x/30
The time it will take them to build the house together will be equal to the amount of work divided by the joint rate.
That will be x divided by 11x/30
= x * 30/11x
= 30/11 hours which is Approximately 2.73 hours
