Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
<span>20 hundred = 20 * 100 = 2000 = 2 * 1000 = 2 thousand. So, it is correct that 20 hundred is equal to 2 thousand.
However, twenty hundredth is twenty parts out of hundred parts. Similarly, two thousandth is two parts out of thousand parts. So, twenty hundredth is 20/100 and two thousandth is 2/1000.
20/100 can also be represented as (20 * 10)/(100 * 10) = 200/1000. So, it can be clearly seen that 20 hundredths is not equal to 2 thousandth. In fact, 20 hundredths is 100 times as much as 2 thousandth.
20/100 = (20 * 10)/(100 * 10) = 200/1000 = (2/1000) * 100

Answer: the answer is A
Step-by-step explanation:
Step-by-step explanation:
Given - For each pair of pants, Pedro has 2 shirts.
To find - Which models show this relationship?
Proof -
Let Pedro has total number of pair of pants = x
Now,
As given
For 1 pair of pants , Pedro has total number of shirts = 2
⇒For x pair of pants , total number of shirts = 2x
So, Total number of clothes Pedro has = x + 2x = 3x
