Answer:

The total time taken by 3 men to trim the hedge would be 80 minutes.

Step-by-step explanation:

1) The time taken by 4 men to trim the hedge is 1 hour or 60 min.

2) One me would take 4 times more time alone i.e. Time taken by only one man would be 4 hours or 240 min.

3) The time taken by 3 men would be 3 times less than time taken by one man i.e. 240/3=80 min.

#of people = 4

time taken for 4 ppl = 1hr / 60mins  

# of people = 3

time taken = 1/x

4 - 1/60

3 - 1/x

cross multiply

x=60/3*4

x=80

hope this helps :)

mark me brainliest :D

Tony misplaced 7 77 stamps from his collection. He knows that each stamp of his is worth $ 0 . 1 5 $0.15dollar sign, 0, point, 1
denis23 [38]
I take it that only 7 stamps are misplaced and that we are asked for the total value of the stamps including those which have been misplaced. 
If each is worth $0.15 then, the total worth of 7 stamps is $1.05. Then, we add this value to the value of his remaining stamps, $5.55, the answer would be $6.60.

Given

See attachment for complete question

Required

Determine the difference between the shortest and the longest

This question implies that we calculate the range.

Range = Longest - Shortest

From the table, we have:

Longest = 8.7m

Shortest = 5.531m

So, we have:

Range = 8.7m- 5.531m

Range = 3.169m
