Answer:
- Part-a: Holly will take 6 hours to complete 5 paintings
- Part-b: Ella will take 2 hours longer to complete 5 paintings.
Step-by-step explanation:
<u>We know that:</u>
- Ella = 1 3/5 = 1 painting
- Holly = 1 3/5 x 3/4 = 1 painting
<u>Work:</u>
- Holly = 8/5 x 3/4 = 1 painting
- => Holly = 2/5 x 3 = 1 painting
- => Holly = 6/5 hours = 1 painting
- => Holly = 6/5 x 5 hours = 5 paintings
- => Holly = 6 hours = 5 paintings
- => Ella = 8/5 hours = 1 painting
- => Ella = 8/5 x 5 hours = 5 paintings
- => Ella = 8 hours = 5 paintings
<u>Final Answer(s):</u>
- Final Answer Part-a: Holly will take 6 hours to complete 5 paintings
- Final Answer Part-b: Ella will take 2 hours longer to complete 5 paintings.
Answer:
X = {8n – 7n – 1 : n ϵ N}
Y = {49 (n –1) : n ϵ N} — (1) [all terms divisible by 49]
X = {8n – 7n – 1}
= (1 + 7)n – 7n – 1
= 1 + nC1 7 + nC2 72 + ….. + nCn 7n – 7n – 1
= nC2 72 + …… + nCn 7n
= 49 [nC2 + nC3 7 + …. nCn 7n-2] — (2)
From (1) and (2),
X is divisible by 49.
Y has all multiples of 49.
X ⊂ Y
