A Ferris wheel can accommodate 40 people in 20 minutes. How many people
Montano1993 [528]

Answer:

360 people in 3 hours. 120 people per hour.

Step-by-step explanation:

How many times do 20 minutes go into 3 hours?

Well, 60 min. ÷ 20 min. = 3

So, 3 x 3 = 9

So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.

So 3 hours would be 9 x 40 = 360

120 people per hour because 40 x 3 = 120

and 20 minutes (3) times equals 1 hour.

String a is 35 centimeters long.string b is 5 times as long as string a .both are necessary to create a decorative bottle .find
yulyashka [42]
First you convert centimeters to meters which will be 35 centimeters-> 0.35 meters

Once you have that, you multiply String A's length (0.35 m) by 5 to find String B's length which will be 1.75 meters.

Now that you have the two lengths you multiply each by 17.
 
17 x 1.75 = 29.75 and 17 x 0.35 = 5.95

Now you just add 29.75 and 5.95 and you get your answer which is
 
35.7 meters
