Answer:
It would be 72% trust me it is correct because this level of questions seems a little to young for me lol
Step-by-step explanation:
If Ann can build the model in 3 hours, then in 1 hour she gets 1/3 of it done. Likewise, if Sam can build the model in 6 hours, then in 1 hour he gets 1/6 of it done. We are looking to find how long it takes when they combine their efforts, so we will add the two together and set it equal to 1/x, x being the number of hours it takes for both of them to get the whole job done. The equation then looks like this: 
. You will have to find the common denominator to add those fractions, and once you do, cross multiply to solve for x.

To make 8 inch tall column approximately 61 coins required.
Given,
Total one cent coins stacked on top of each other in a column = 50
Height of column = 378 inches
Approximate height of one coin = ( 50 / 378)
= 0.132 inches
To make an 8 inches tall stack No of coins required will be:
Number of coins required = ( total height / height of one coin )
= ( 8 / 0.132 )
= 60.60
≅ 61 coins
To make 8 inch tall column approximately 61 coins required.

Alright, so we know that 1 inch is 16 feet on the model. The model that we have is 11.5 inches in length.
To figure this out, simply multiply 11.5 by 16, which equals 184.
This gives us a ratio of 11.5 : 184, which is the same as 1 : 16. You can also write proportions as fractions, so 11.5 / 184 and 1/16 are the same, both equaling 0.0625.
The final answer is 184 ft
