19.50 divided by 3.25 is 6
6 family members in total.
Answer: 21, 63
<u>Step-by-step explanation:</u>
We need to find two geometric means between 7 and 189.
The Geometric Sequence is: 7, ____, ____, 189
Let's find r (common ratio):
We can see that the common ratio will be multiplied by itsely 3 times in order to get from 7 to 189:
7 r³ = 189
r³ = 27
∛r³ = ∛27
r = 3
Now that we know the common ratio is 3, we can multiply 7 and 3 to get the next term (21), and multiply that by 3 to get the third term (63), and multiply that by 3 as a check to confirm we get 189.
7 x 3 = 21
21 x 3 = 63
63 x 3 = 189
The completed Geometric Sequence is: 7, <u>21</u>, <u>63</u>, 189
7% of 4700 = 329
740 x 6 = 4440
Total cost = 329 + 4440 = 4769
The extra cost of instalments = 69

Answer:
Base
Step-by-step explanation:
Every solid shape has to have a base that they sit/stand on. Because the base is the bottom of the shape and lies on the table. Hence, answering your question.
