63 = 0.63×10² = 126/2 = 3×21 = √3969 = 77₈
The last is as a base-8 number.
Answer:
Step-by-step explanation:
Look at the differences between terms.
The initial term is -12, and each successive term is 7 more than the preceding term:
a₂ = a₁ + 7
a₃ = a₂ + 7
Etc.
a₁₃ = a₁ + (13-1)7 = -12 + (12)7 = 72

Answer:
4.25 pound
Step-by-step explanation:
Ratio is the quantitative relation between two amounts, which is being compared. In this question we are considering the ratio of weight to time consumed.
At the age 0
Weight = 2 pound
At the age 4 months
Weight = 3.5 pound
Proportion of Change = Change in Weight / Change in time = (3.5 - 2) / (4-0) = 1.5 / 4 = 0.375 pound per month
Weight after 6 months = 2 + (6 x 0.375 pond per month )= 4.25 pound
