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.

So, buying m tables give a total of $4m+3$ seats.

If we want this total to be at least 75, we have

$4m+3\geq 75 \iff 4m\geq 72 \iff m\geq 18$

Suppose why varies directly with X. Write a variation equation that relates x and y

diamong [38]

Answer:

$x = y - 6.4$

Steps :

1. Create an equation

If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

$x - 4 = y - 10.4$

2. Isolate variable X by adding 4 to both sides

$x = y - 6.4$

3. (Optional) Check Answer by plugging given values into the equation

$(4) = (10.4) - 6.4$

4 = 4 is a true statement
