First let's covert ft to inches:
tiles- 6×6 = 36 sq. in.
floor- 3ft×2ft. = (3×12)×(2×12) = 36×24
= 864 sq. in.
now divide total (floor) by each tile:
864÷36 = 24 tiles

Answer:
<u>16 ounces</u> of the 30% hydrochloric acid solution is used in order to obtain the 25% solution.
Step-by-step explanation:
Let amount of 30% ounces be 'x' and that of 15% ounces by 'y'.
Given:
Total amount on mixing both the solution = 24 oz
∴
Also, the total acid content in the resulting 25% solution is equal to the sum of the acid contents in 30% and 15% solutions.
∴
Now, plug in 'x' from equation (1) into equation (2). This gives,
ounces
Therefore, ounces
Hence, 16 ounces of the 30% hydrochloric acid solution is used in order to obtain the 25% solution
