Wipes

The mummy wiped out the square wipes, and the veil was next to each other on the cord stretched out between the two trees. She used a cord of 7.5 meters in length, requiring about 8 dm on each side of the trunk. All wipes are 45 cm wide. The mummy leaves a gap of at least 10 cm between the wipes and the trunk. The clothes do not overlap and do not have them folded. How many wipes can hang up on a stretched cord?

Final Answer:

n =  12

Step-by-step explanation:

$$\begin{gathered} a=7.5-2\cdot 0.8-2\cdot 0.1=5.7\text{m} \\ b=45\text{cm}\to \text{m}=45:100\text{m}=0.45\text{m} \\ {n}_0=a/b=5.7/0.45=\frac{38}{3}=12\frac{2}{3}\doteq 12.6667 \\ n=\lfloor n_0\rfloor =\lfloor 12.6667\rfloor =12 \end{gathered}$$
