At an amusement park, 25 riders ride the race cars every 30 minutes and 20 riders ride the spinning swings every 20 minutes.
which ride will have more riders each hour and how many more?

Spinning Swings

10 more riders

Step-by-step explanation:

To find which ride will have more riders each hour, we need to first convert an hour into minutes.

1 hour = 60 minutes

Now we let's first find how many riders there will be in the race cars.

So there are 25 riders every 30 minutes.

in 60 minutes there will be:

25 x 2 = 50 Riders

Now for the spinning swings there are 20 riders every 20 minutes.

In 60 minutes there will be:

20 x 3 = 60 Riders

Therefore, the spinning swings will have more riders as 60 > 50.

Now to find how many more riders there will be in the spinning swings.

We simply subtract the total number of riders of each ride from each other.

Race Cars = 50

Spinning Swings = 60

60 - 50 = 10

There will be 10 more riders in the spinning cups than the race cars.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
