Answer:
a₄₂ = 107
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₂₇ = 66 , then
a₁ + 26d = 66 , that is
- 12 + 26d = 66 ( add 12 to both sides )
26d = 78 ( divide both sides by 26 )
d = 3
Then
a₄₂ = - 16 + (41 × 3) = - 12 + 123 = 111
Diameter is UF
answer is B. UF
Answer:
12
Step-by-step explanation:
First fraction:
Numerator:
(17/40 + 0.6 - 0.005) = 1.02
1⅕ = 1.2
(1.2 ÷ 1.02)×1.7 = 2
Denominator:
5/6 + 4/3 - 53/30
Lcm: 30
(5×5 + 4×10 - 53)/30
12/30 = 0.4
Fraction value: 2/0.4 = 5
Second fraction:
4.75 + 7.5 = 12.25
33 ÷ 33/7
33 × 7/33 = 7
12.25/7 = 1.75
1.75 ÷ 0.25 = 7
Final answer:
5 + 7 = 12
Answer:
3 and 11
Step-by-step explanation:
