Answer:
Step-by-step explanation:
We have a geometric sequence with:
, 
, and 
Where
Sn is the sum of the sequence
r is the common ratio
is the first term in the sequence
n is the number of terms in the sequence
The formula to calculate the sum of a finite geometric sequence is:
Then:
Now we solve for
The singles digit is 0.
The 2 is the tens digit and the 4 is the hundreds digit.
So first start out by writing an expression for the cost of the child and the adult separately.
Child:
6 + 1r ($6 + $1 per ride)
Adult:
10 + 1.5r ($10 + $1.50 per ride)
to find how much more the adult will spend, just do Adult Expression - Child Expression which will be:
10 + 1.5r - (6 + 1r) just simplify this
For Part B, use your equation from part A where r = 7
Answer:
this is the graph and answer :D
Step-by-step explanation:
The vlaue of z is 27°
Step-by-step explanation:
Given,
The angle is 63°
To find the value of z
We know that the diagonals of rhombus perpendicularly bisect each other.
Again,
z+63°+90° = 180° [ sum of all the triangle is 180°]
or, z = 27°
