If jummai is 12years old and Tunde is 8years old and they share 15bananas in the ratio of their ages how many will each have sho
1 answer:
Jummai and Tunde will each have 9 and 6 bananas respectively.
For the given ratio case we use the sharing ratio criterion to solve the problem.
Jummai is 12 years old.
Tunde is 8 years old.
Their ages are in ratio of;
A = 12 : 8
A = 3 : 2
The ratio's sum is 5.
15 bananas total are available for sharing.
Jummai will have bananas
= (15 x 3/5) = 9
Tunde will have bananas
= (15 x 2/5) = 6
Jummai and Tunde will each have 9 and 6 bananas with them.

Answer:
The beam initial temperature is 5 °F.
Step-by-step explanation:
If T(t) is the temperature of the beam after t minutes, then we know, by Newton’s Law of Cooling, that
where is the ambient temperature,
is the initial temperature,
is the time and
is a constant yet to be determined.
The goal is to determine the initial temperature of the beam, which is to say
We know that the ambient temperature is , so
We also know that when the temperature is
and when
the temperature is
which gives:
Rearranging,
If we divide these two equations we get
Now, that we know the value of we can use it to find the initial temperature of the beam,
so the beam started out at 5 °F.
