I need to help to ring the area of the base plz help me

6

Step-by-step explanation:

the area of the base is the triangle base

the area of a triangle is bh/2

that looks like a perpendicular sign in the top left so b = 3 and h = 4

so area = 3*4/2 = 6

hope this helps:)))))

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)
