Barbara hiked 7 miles from one point point of a mountain to another point before stopping for a break. that is 27% of the entire trip. how many miles in barbara's complete hike

25.93 miles

Step-by-step explanation:

Given

27% > 7 miles

1% > (7 ÷ 27) miles

100% > (7 ÷ 27) x 100 miles = 25.93 miles

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)

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
