Can someone please help

1) 32 yd^2

2) 15 ft^2

3) 40 in^2

4) 9 in^2

5) 35 yd^2

6) 104 ft^2

7) 18 ft^2

8) 16 in^2

9) 90 yd^2

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)

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
