three numbers are in the ratio of 4:5:6. if the sum of the largest and smallest exceeds the third number by 55 find the number

ATQ

Let us assume the ratio as 4x,5x and 6x

A.T.Q.

6x + 4x = 5x + 55

=> 10x = 5x + 55

=> 10x − 5x = 55

=> 5x = 55

=> x =

x = 11

Therefore-:

First no. =4×11=44

Second no. =5×11=55

Third no. =6×11=66

Hence the three numbers are 44,55 and 66.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

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)
