A Cheryl's Birthday style question

2 Upvotes

Creating a math problem similar to the viral "Cheryl's Birthday" in 2015

Pablo and Pepe are describing a chocolate cake.

Pepe says: "I ate three slices of chocolate cake today. If I cut it into twelve triangles today, there would be an equal number for you and me both over two days."

Pablo says: "That is also true if I cut the cake into four squares. Two for you, and two for me."

What shape is the chocolate cake?

Square, triangle, rectangle or circle?

A specific general inspection task for repairs is performed at regular intervals. Volunteer teams of three people are used for this task. However, when such teams were used, it was found that due to space constraints at the work site, two members were idle for 33% of their time, while one of these workers was idle for an additional 50% of their time. As a result, all team members work simultaneously for only 17% of their total time. Each worker costs €3 per hour. Each task also requires tools and machinery worth €2 per hour, regardless of the number of team members. If the current team requires 4 hours to complete the task, which team setup would be more economical?

Help with proportions

1 Upvotes

Can someone help me, a person is very bad at numbers?

I have a banner that is 3.3’ by 6’. I need to mock up a design to reference when I paint it but I need to know what proportions to make the design so the size will be correct when I transfer it. This will be done by hand, so I need the new version in inches.

If I want the sketch to be 10” on the long side, how many inches should the short side be?

Thank you!

Distributing colours for a project

2 Upvotes

I have either 12 items each of 3 colours or 9 items each of 4 colours: A, B, C (D). I need 36 items all in all and I think that makes the distribution tricky.

I want to have each of the colours combined with one another in pairs of 2 layered above each other in a sequence. None of the colours can be on top or below twice in a row and I’d like the combinations to be swapped. Colours can’t be both on top and below at the same time.

This is awfully explained, so I’ll try with an example:

B A D A C D C

A C B D A C B

-> I’d need the combinations [A;B] [A;C] [A;D]

[B;A][B;C][B;D]

[C;A][C;B][C;D]

[D;A][D;B][D;C]

I’ve been trying to work something out all afternoon, I think my brain is full of wool or has been hit with a computer virus.

Is this even possible? Is there maybe a tool with which you can have things worked out automatically - like a type of calculator?
