The value of 5 in the ten thousands place is what fraction of the value of 5 in the hundred thousands place?

one-tenth

Step-by-step explanation:

The value of 5 in the ten thousands place (T) is 5 * 10,000 = 50,000

The value of 5 in the hundred thousands place (H) is expressed as:

5 * 100,000 = 500,000

Using the expression:

T = x of H

x is the required fraction

50,000 = x of 500,000

Divide both sides by 500,000

50,000/500,000 = 500,000x/500,000

50,000/500,000 = x

x = 50,000/500,000

x = 5/50

x = 1/10

Hence the value of 5 in the ten thousands place is one tenth the value of 5 in the hundred thousands place

i dont know

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
