Answer:
.
Step-by-step explanation:
We have been given a geometric sequence 18,12,8,16/3,.. We are asked to find the common ratio of given geometric sequence.
We can find common ratio of geometric sequence by dividing any number by its previous number in the sequence.

Let us use two consecutive numbers of our sequence in above formula.
will be 12 and
will be 18 for our given sequence.

Dividing our numerator and denominator by 6 we will get,

Let us use numbers 8 and 16/3 in above formula.



Therefore, we get
as common ratio of our given geometric sequence.
Answer:
15x because the air ballon drops 15 meters each time the elevation decreases
Step-by-step explanation: Im not sure if this is what youre looking for but it drops 15 meters each time, 5 times so the change would be 15x and the x is used as how mant different times the elevation drops
The solution would be like
this for this specific problem:
86 + 80 = 166
166 / 2 = 83
<span>So the class average is 83.
</span><span>In colloquial language, an </span>average<span> is the sum of a list of numbers divided by the
number of numbers in the list.</span>

Answer:
10 inches
Step-by-step explanation:
Use the formula for the area of a trapezoid. Fill in the given information and solve for the unknown.
A = 1/2(b1 +b2)h
50 in² = (1/2)(3 in +7 in)h
50 in²/(5 in) = h . . . . . . . . . . divide by the coefficient of h
10 in = h
The height of the trapezoid is 10 inches.
