Answer:
The value of n = 9th term
Step-by-step explanation:
Given:
In an arithmetic series
a3 = 15
d = -3/2
an = 6
Find:
The value of n
Computation:
In an arithmetic series
An = a + [n - 1]d
where,
An = last term
a = first term
n = number of term
d = common difference
So,
a3 = a + 2d
15 = a + 2(-3/2)
15 = a - 3
a = 18
An = a + [n - 1]d
6 = 18 + [n - 1][-3/2]
-12 = [n-1][-3/2]
8 = n - 1
The value of n = 9th term

Answer:
a) π/6
b) 7π/4
c) 108°
d) 405°
Step-by-step explanation:
Multiply by π/180° or 180°/π, as appropriate.
a) 30° = 30π/180 = π/6 radians
b) 315° = 315π/180 = 7π/4 radians
c) 3π/5 × 180°/π = 108°
d) 9π/4 × 180°/π = 405°
Answer:
4%
Step-by-step explanation:
1. Convert the problem to an equation using the percentage formula: P% * X = Y.
2. P is 10%, X is 150, so the equation is 10% * 150 = Y.
3. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
