Answer:
448
Step-by-step explanation:
aₙ = a₁ + (n-1)d
a₈ = a₁ + (8-1)d = a₁ + 7d
a₁₂ = a₁ + 11d
a₈ + a₁₂ = 246 = 2a₁ + 18d a₁ + 9d = 123
a₁₀ + a₁₄ = a₁ + 9d + a₁ + 13d = 298 a₁ + 11d = 149
2d = 26
d = 13
a₁ = 6
a₃₅ = 6 + (35-1) x 13 = 448
The answer is A zinc is oxidized and copper gets reduced
Answer: 11 muffins
Step-by-step explanation:
Since Maria mixes 1/4 cup white sugar with 2/3 cup brown sugar, this will give us a mixture of:
= 1/4 + 2/3
= 3/12 + 8/12
= 11/12
Ww are then told that she uses 1/12 cup of the mixture to top each muffin. Therefore, the number of muffins that she can top will be:
= 11/12 ÷ 1/12
= 11/12 × 12/1
= 12
She can top 11 muffins.
