The nth term of a sequence is 3n²-1

The nth term of a different sequence is 30–n²

Find the only number that is in both of these sequences.

Answers

Answer: The number is 26.

Step-by-step explanation:

We know that:

The nth term of a sequence is 3n²-1

The nth term of a different sequence is 30–n²

We want to find a number that belongs to both sequences (it is not necessarily for the same value of n) then we can use n in one term (first one), and m in the other (second one), such that n and m must be integer numbers.

we get:

3n²- 1 =  30–m²

Notice that as n increases, the terms of the first sequence also increase.

And as n increases, the terms of the second sequence decrease.

One way to solve this, is to give different values to m (m = 1, m = 2, etc) and see if we can find an integer value for n.

if m = 1, then:

3n²- 1 =  30–1²

3n²- 1 = 29

3n² = 30

n² = 30/3 = 10

n² = 10

There is no integer n such that n² = 10

now let's try with m = 2, then:

3n²- 1 =  30–2² = 30 - 4

3n²- 1 = 26

3n² = 26 + 1 = 27

n² = 27/3 = 9

n² = 9

n = √9 = 3

So here we have m = 2, and n = 3, both integers as we wanted, so we just found the term that belongs to both sequences.

the number is:

3*(3)² - 1 = 26

30 - 2² = 26

The number that belongs to both sequences is 26.

Antonio ran 129 laps at the park. Alan ran 20% more than that. how many laps did Alan run

Answers

Answer:

154.8

Step-by-step explanation:

20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.

Equation: 20/100= 0.2

                0.2* 129= 25.8

                25.8+129= 154.8

Alan ran 154.8 laps.

Shirts are 30% off. The original price of one shirt is $12. What is the total
cost, in dollars, of 2 shirts, at the sale price, including a 5% sales tax? *

Answers

2 shirts = $24
To find the sale price, convert 30% to a decimal by dividing by 100, = 0.30

24 x 0.30 = 7.20 discount.
24 - 7.20 = 16.80 for 2 shirts

Now we add the sales tax, 0.05 (converted like the sale percentage was)

16.80 x 0.05 = 0.84 tax
Add tax to the price of the shirts
16.80 + 0.84 = $17.64
