Answer:
Step-by-step explanation:
Range = Maximum value - minimum value
= 69 - 13
= 56
<span>Let us assume that the rate of decay follows a 1st
order reaction. Therefore the formula for rate of decay is:</span>
<span>A = Ao e^-kt --->
1</span>
Where,
A = final value after time t
Ao = initial value at t zero
k = rate constant
t = time elapsed
First let use find for the value of constant k. We know
that the formula for half-life is:
t-half life = ln 2 / k
Finding for k:
5730 = ln 2 / k
k = 1.21 * 10^-4 yr^-1
Since it is stated that A = 0.00061 Ao, therefore
substituting all the values into equation 1:
0.00061 Ao / Ao = e^(-1.21 * 10^-4 yr^-1 * t)
Finding for t:
t = 61,173.98 years

Answer:
144 cloves
Step-by-step explanation:
You separate 42 bulbs of garlic into two groups:one for planting and one for cooking.
We have a ratio of planting to cooking
Planting : Cooking
You will plant 3 bulbs for every 4 bulbs that you will use for cooking.
Hence: 3 : 4
The total of their proportion = 3 + 4 = 7
Hence:
The number of garlic you plant =
3/7 × 42 = 18 bulbs of garlic
The number of garlic you use to cook =
4/7 × 42 = 24 bulbs of garlic
We are also told that:
Each bulb has about 8 cloves. How many cloves of garlic will you plant?
From the calculation above , we know the number of bulbs of garlic been planted
= 18 bulbs.
Hence:.
1 bulb = 8 cloves
18 bulbs = x
x = 8 cloves × 18 bulbs
x = 144 cloves
Therefore, you will plant 144 cloves of garlic
