Step-by-step explanation:

80 containers every 20min

theirs is 60min in an hr

80 for 20min

80 for 20min

+80 for 20min

240 for 60min.

Answer : The number of containers of cookies machine fill in 8 hours can be, 1920

Step-by-step explanation :

As we are given that a machine fills 80 containers of cookies in 20 minutes. Now we have to determine the number of containers of cookies could the machine fill in 8 hours.

First we have to convert minutes into hours.

As, 60 minutes = 1 hour

So, 20 minutes = hour

Now we have to determine the number of containers of cookies could the machine fill in 8 hours.

As, in hour the number of containers of cookies can machine fill = 80

As, in 8 hours the number of containers of cookies can machine fill =

Therefore, the number of containers of cookies machine fill in 8 hours can be, 1920

1920 containers of cookies  could be filled by the machine in 8 hours.

Step-by-step explanation:

To solve this problem, we will follow the steps below;

First, lets change 8 hours to minutes

8 hours = 8 × 60 =480 minutes

Now using proportion,

Let x be the number of containers of cookies the machine can fill in 8 hours

20 minutes = 80 containers

480 minutes = x

cross-multiply

20×x = 480×80

20 x =38400

Divide both-side of the equation by 20

=

(At the left-hand side of the equation 20 will cancel-out 20 leaving us with x while at the right-hand side of the equation 28400 will be divided by 20)

x= 1920 containers.

Therefore, 1920 containers of cookies  could be filled by the machine in 8 hours.

The number of containers of cookies machine fill in 8 hours can be, 1920

Step-by-step explanation: You would need to find how many containers of cookies they make in a hour which is 240 so then 240 times 8 is 1,920

The answer to #15 is 42

Step-by-step explanation:

Hope this helps, sorry I was confused with 17

1,920

Step-by-step explanation:

You would need to find how many containers of cookies they make in a hour which is 240 so than 240 times 8 is 1,920

D) 1, 920

Step-by-step explanation:

The machine fills 80 container/20 minutes which means 4 container/1 minutes

To find the answer convert 8 hours to minutes then multiply it by 4/1.

1 hour = 60 minutes

4/1 × 8 (60)

4/1 × 480=1920

Step-by-step explanation:

i would say is that every 20 mins its 80 that means every hour its 240 so just multiply it by 8 idk if its right but thats what i would do
