Find the value of x round to the nearest tenth

Step-by-step explanation:

Note. You should put the item you are trying to solve for in the numerator when using the sine law.

sin(x) / 15 = Sin 27 / 11

sin(x) = 15 * sin(27 / 11

sin(x) = 0.4539

sin(x) = 15 * 0.4539/11

sin(x)  = 6.809 / 11

sin(x) = 0.6191

x = sin-1(0.6191)

x = 38.3

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)

it's
