Answer:
729
Step-by-step explanation:
The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation:
2n - 5 = 11
When n = 3:
2(3) - 5 = 1 ≠ 11
When n = 8:
2(8) - 5 = 11
When n = 9:
2(9) - 5 = 13
When n = 14:
2(14) - 5 = 23
The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

To calculate the remaining caffeine, we use the radioactive decay formula which is expressed as An = Aoe^-kt where An is the amount left after t time, Ao is the initial amount and k is a constant we can calculate from the half-life information. We do as follows:
at half-life,
ln 1/2 = -k(6)
k = 0.12/hr
An = 80e^-0.12(14)
An = 15.87 mg

Answer:
6Apples
Step-by-step explanation:
Number of apples required for the recipe = 1.2kilograms
But we know that 1000g = 1kg
So;
1.2 kg will give:
1.2 x 1000 = 1200kg
Average mass of the apple = 200g
So;
The number of apples used = 
= 6Apples
