Answer:
<h3>The 12th term is 1771470</h3>
Step-by-step explanation:
Since the above sequence is a geometric sequence
An nth term of a geometric sequence is given by
where a is the first term
r is the common ratio
n is the number of terms
From the question
a = 10
To find the common ratio divide the previous term by the next term
That's
r = 30/10 = 3 or 90/30 = 3 or 270/90 = 3
Since we are finding the 12th term
n = 12
So the 12th term is
<h3>A(12) = 1771470</h3>
Hope this helps you
Since dimes + quarters = 22
And dimes are 0.10 cents as quarters = 0.25 cents
Let’s make d = dime, q = quarter
d + q = 22
0.10d + 0.25q = 4.00
Let’s use substitution
d + q = 22, get d or q by itself
d = 22 - q (plug into second equation)
0.10(22-q) + 0.25q = 4
2.2 - 0.10q + 0.25q = 4
2.2 + 0.15q = 4
0.15q = 1.8, q = 12
Since there are 12 quarters you know there are 10 dimes (22 in total)
Solution: 10 dimes, 12 quarters
Answer:
Option 2
Step-by-step explanation:
12 chaperones to 210 students....12/210 reduces to 2/35
18/300 reduces to 3/50
20/350 reduces to 2/35
8/160 reduces to 1/20
14/260 reduces to 7/130
so the same ratio would be Jefferson High School
The answer is (1,3) because when you graph it you can see it is on the parabola.
