Answer:
to convert a fraction to a decimal you have to divide the numerator with the denominator.
so Rylie ate 12 grapes out of 20= 12/20
12/20=0.6
Step-by-step explanation:
Answer:
The other angle is 58 degrees
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let the other angle be x
x+122 = 180
Subtract 122 from each side
x+122-122= 180-122
x = 58
The other angle is 58 degrees
Using an exponential function, it is found that the half-life of the substance is of 5.23 units of time.
<h3>What is the exponential function for the amount of a substance?</h3>
The function is given by:

In which:
- A(0) is the initial value.
- k is the exponential decay rate.
The parameters are given by:
A(0) = 48, k = 0.1325.
Hence the equation is:

The half-life is the amount of time for which A(t) = 0.5A(0) = 24, hence:






t = 5.23.
