Hello friend ,. I hope it's helps you

The amount of the substance (At) at any time t is calculated through the equation,
At = (A0)(e^-kt)
where A0 is the initial amount and k is constant.
For the half-life,
ln (At / A0) = ln 0.5 = -k(5270 years)
The value of k is 1.3153x10^-4 / year.
Substituting this value to the same equation, where At = 0.25A0
ln 0.25 = -(1.3153 x 10^-4)(t)
The value of t from this equation is 10540 years. The closest value to this is letter A.
Answer:
7, 1, -7, -1.
Step-by-step explanation:
5+1/2(14b-8) = -6
5 + 7b - 4 = -6
7b + 1 = -6
7b = -7
b = -1
So, your answer will be 7, 1, -7, -1.
Hope this helps!
Here are the completed tables
Gallons Quart
1 4
2 8
5 20
7 28
Quart Pint
1 2
3 6
6 12
8 16
Pint Cup
1 2
3 6
5 10
9 18
The capacity of the objects are:
Swimming pool - 5000 gallons
Watering can - 8 quarts
Juice box - 2 pints
Soup bowl - 2 cups
The measurement from least to greatest is: 6 pints, 2 galloons, 18 cups, 6 quart.
<h3>How would the tables be filled?</h3>
In order to fill the tables, the unit of conversion has to be known:
1 gallon = 4 quart
- 2 gallon = 2 x 4 = 8 quarts
- 5 gallons : 5 x 4 = 20 quarts
- 7 gallons: 7 x 4 = 28 quarts
1 quart = 2 pints
6 pint / 2 = 3 quarts
12 / 2 = 6 quarts
8 x 2 = 16 pints
<h3>
How to order the measurment from least to largest?</h3>
In order to order the measurement, all the measurements have to be in the same units. All the units would be converted to cups
1 quart = 4 cups
4 x 6 = 24 cups
1 galloon = 16 cups
16 x 2 = 32 cups
1 pint = 2 cups
6 x 2 = 12 cups
