Answer:
108 th term is zero
Step-by-step explanation:
The nth term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₉ = 99 and a₉₉ = 9 then
a₁ + 8d = 99 → (1)
a₁ + 98d = 9 → (2)
Subtract (1) from (2) term by term to eliminate a₁
0 + 90d = - 90
90d = - 90 ( divide both sides by 90 )
d = - 1
Substitute d = - 1 into (1) for value of a₁
a₁ + 8(- 1) = 99
a₁ - 8 = 99 ( add 8 to both sides )
a₁ = 107
Then
107 - (n - 1) = 0
107 - n + 1 = 0
- n + 108 = 0 ( subtract 108 from both sides )
- n = - 108 ( multiply both sides by - 1 )
n = 108
The 108th term is zero
Answer:
<em><u>11 rides</u></em>
Step-by-step explanation:
<u>First Step - Subtract 6 from 40 because that will not be of use for now.</u>
<em>40-6=34</em>
<u>Next Step - divide 34 by 3 to find the number of rides.</u>
<em>(you will end up with a decimal so I rounded it up to a whole number.)</em>
<em>34/3=11 (rounded)</em>
<em><u>The final answer is 11 rides.</u></em>
<em>Hope this helped :)</em>

12/21 in its simplest form is 4/7.
To find this out we need to divide the numerator and denominator by the GCF of 12 and 21 which is 3.
12/21
12 ÷ 3 = 4
21 ÷ 3 = 7
4/7
12/21 in its simplest form is 4/7.
12/21 = 4/7
