Answer:
Missing number ⇒ 27
Step-by-step explanation:
Given sequence is:
1, 1, 4, 8, 9 , ?, 16, 64
We need to find the missing number of the sequence.
Solution:
We can see the series consist numbers 1, 2, 3, 4, 5.. of power 2 and 3 each respectively. So, the series is
such that

Therefore, missing number is 
Answer:
A, D, E
Step-by-step explanation:
A) 32/3 x 9/10 = 96/10 = 9.6
D) 1/8 x 32/3 = 4/3 = 1.33
E) 2/3 x 3/5 = 2/5 = 0.4
Answer:
The angle is 60°
Step-by-step explanation:
A supplement angle is the angle whose sum is equal to 180°.
The supplement angle = 180° - x
A complement angle is the angle whose sum is equal to 90°.
The complement angle = 90° - x
Given,
supplement angle = 4 × complement angle
(180° - x) = 4 × (90° - x)
180° - x = 360° - 4x
4x - x = 360° - 180°
3x = 180°
x = 60°
The supplement angle = 180° - x
⇒ 180° - 60°
⇒ 120°
The complement angle = 90° - x
⇒ 90° - 60°
⇒ 30°
You would solve using elimination.
y=1
x=-1
