Answer:
C
Step-by-step explanation:
√18x / √50
= √9*√2x / √25*√2
= 3√x / 5

So if you take the two pieces of paper they would be triangles because he cut it from one corner to the other. Each shape would have a total of three sides; one of those sides would be an angle. Hope this helps
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.

Explanation:
Step 1 - Convert the mixed numbers into decimals
7 2/5
2/5 • 20/20 = 40/ 100
40/ 100 = 0.4
0.4 + 7.0 = 7.4
Therefore, 7 2/5 = 7.4
Step 2 - Convert the mixed numbers into decimals
7 3/8
3/ 8 = 0.375
0.375 + 7.0 = 7.375
Therefore, 7 3/8 = 7.375
Step 3 - Compare
7.4 < 7.375
So, 7 2/5 is less than 7 3/8
