Answer:
see explanation
Step-by-step explanation:
The geometric mean of 2 numbers a and b is 
The third term is the geometric mean of the first and fifth terms, that is
a₃ = 
= 31.5
The second term is the geometric mean of the first and third terms, that is
a₂ = 
= 10.5
The fourth term is the geometric mean of the third and fifth terms, that is
a₄ = 
= 94.5
Thus the sequence is
3.5, 10.5, 31.5, 94.5, 283.5
Assuming the question is : Choose a height for the line
Cubic = Volume, we can square root this 3 times to get ONE possible number that could be multiplied to make the volume
One possible height for the line could be, 10.16 inches (2 DP)
1km=0.62 miles
so multiply 1km by 5 to get 5km
multiply 0.62 by 5 to get km to miles
0.62 times 5=3.1
answe ris 3.1 miles
Answer:
x=14
Step-by-step explanation:
This is asking for the ratio of A to B.
The x-10 is 1.
The 28 is 7.
Find the scale factor by executing 28/7=4.
So, you would want polygon A to be 4 in order to be proportional to polygon B.
Now, you can just guess and check that 14-10=4
Or, you can set up the equation as follows: x-10 = 4
+10 +10
x = 14 is your answer.
True, bc they add up to 180 and are the same size.
