The answer to (-4.5)(-6)(5.4)= 137.7
To serve 3 you half the recipe so divide each number by 2
3/4 cup/2 = 3/8 cup granulated sugar
1 cup/2 = 1/2 cup of evaporated milk
1/3teaspoon/2 = 1/6 teaspoon of vanilla
12 slices/2 = 6 slices of French bread
If
is the amount of strontium-90 present in the area in year
, and it decays at a rate of 2.5% per year, then

Let
be the starting amount immediately after the nuclear reactor explodes. Then

or simply

So that after 50 years, the amount of strontium-90 that remains is approximately

or about 28% of the original amount.
We can confirm this another way; recall the exponential decay formula,

where
is measured in years. We're told that 2.5% of the starting amount
decays after 1 year, so that

Then after 50 years, we have

Answer:
7
Step-by-step explanation:
Formula=area of base x height / 3
A= ( 3 x 1 ) x 7 / 3
A= 3 x 7 / 3
A= 21 / 3
A= 7
