58% of 121 is (121*0.58) = 70.18

58% is about 72-2.4=69.6

Lisa [10]

Answer:

16.5

Step-by-step explanation:

Given that :

Number of refuge tour guides = 2

Number of tour guides = 11 per tour guide

Duration of each tour = 45 minutes

To calculate the person hour per day for the tour :

Person hour per day = (Total minute spent per day / 60)

Total minutes spent per day= (Number of tour guides) * (Number of refuge tour guides) * (duration per tour)

Total minute spent = (2 * 11 * 45) = 990 minutes

Person hour per day = 990 / 60

= 16.5

LuckyWell [14K]

Answer:

  1 : 4

Step-by-step explanation:

Let x represent the amount of 30% solution for 1 unit of 5% solution. Then the amount of acid in the mix is ...

  0.30x + 0.05·1 = 0.10·(x +1)

  0.30x + 0.05 = 0.10x + 0.10 . . . . eliminate parentheses

  0.20x = 0.05 . . . . . . . . . . . . . . . . subtract 0.05+0.10x

  x = 0.05/0.20 = 1/4

That is, the ratio x : 1 is 1 : 4.
