Answer: 6 cm
Step-by-step explanation:
A = b(h) / 2
9 = b(3) / 2
9(2) = b(3)
18/3 = b
6 = b
b also known as base stands for AB
Answer:
C) z = 1/2
Step-by-step explanation:
4z + 5 = 7
4z = 2
z = 1/2
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be
= 80
ii) let the second term be
=
. r = 80 × r = 60 ∴ r =
= 0.75
iii) let the third term be
=
. r = 60 × r = 45 ∴ r =
= 0.75
iv) let the fourth term be
=
. r = 45 × r = 33.75 ∴ r =
= 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.
