Answer: 30 dominoes in total.
Step-by-step explanation:
Each line is 21 inches long.
the space between dominoes is 1 + 1/2 inches.
(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,
The we have N + 1 dominoes per line, and the distance is:
N*(1 + 1/2)inches = 21 inches
If we find N, we can find the number of domineoes in each line:
N = 21/(1 + 1/2) = 14
This means that we have 14 + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.
Yes. All you have to do is simplify the fraction to its lowest term.
If you would like to know a number you can square and the answer is bigger than 400 but smaller than 500, you can calculate this using the following step:
20^2 = 400 < 21^2 = 441 < 22^2 = 484 < 500
There are two correct results: 21 and 22.
Given parameters:

Make the fraction decimal;
= -2.4
So;
-2.4 + 15.3 = 12.9
