where n is the number, you always take away 5 and you add 45 because that is the first number of the sequence
Final answer:
The nth term for the given arithmetic sequence 45, 40, 35, 30 is 50 - 5n.
Explanation:
The given sequence
45, 40, 35, 30
is an arithmetic sequence with a common difference of -5.
The general formula for the nth term (an) of an arithmetic sequence is:
an = a1 + (n-1)d
where a1 is the first term and d is the common difference.
Plugging in the values from the given sequence, we can find the nth term:
an = 45 + (n-1)(-5)
Simplifying further, we get:
an = 50 - 5n
So, the nth term of the sequence is 50 - 5n.

The expression for the total number of cards in n deck of cards is 52n.
What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of decks of cards = n
Number of cards in a deck = 52
Now,
The number of cards in n deck of cards.
= 52 x n
= 52n
Thus,
The number of cards is 52n.

Csquared=Asquared+Bsquared
But you are finding out A, not C, so you must rearrange the equation.
Asquared=Csquared-Bsquared
Asquared= 484-256
Asquared=228
A=Square root of 228
A=15 :)

1pound=16ounches
1oz=1ounce
1ton=2000pounds=2000 times 16=32000oz
therefor just divide
134893oz/16=pounds=8430 and 13/16 pounds or 8430.8125 pounds
to find tons, just divide the pounds by 2000
8430.8125/2000=4.21541 tons
134893oz=8430.8125 pounds=4.21541 tons

Lateral surface area of a cone: L = πrs = πr√(r^2 + h^2)
L = π(9)√(9^2 + 40^2)
L = 1159.248
Therefore, the correct answer is the last option. Hope this answers the question. Have a nice day.
To solve this problem, we have to use the formula of lateral surface area of a cone and substituting the values into the formula and then solve.
The lateral surface area of this cone is 2260.8in^2
Lateral Surface Area of a Cone
The lateral surface area of a cone is calculated using
The data in the question are
- diameter = 18in
- radius = 9in
- height = 40
- π = 3.14
Let's substitute the values into the equation and solve
