<h3>Answer:</h3>

a_n = 23 +12(n -1)

<h3>Explanation:</h3>

The nth term of an arithmetic sequence is explicitly defined as a_n = a_1 +d(n -1) where a_1 is the first term of the sequence and d is the the common difference.

From the given first five terms of the sequence we can see that the first term is 23 so a_1 = 23.

The common difference, d, can be calculated by a_n - a_{n -1} so we'll find the common difference of the given sequence by letting n = 2

d = a_2 - a_{2 -1} \\d = a_2 -a_{1} \\d = 35 -23 \\ d = 12.

Now let's plug everything we know.

a_1 = 23

d = 12

a_n = 23 + 12(n -1)

During a carpet sale, a carpet company sold $6,792 worth of carpet. If they sold 849 square yards of carpet, what was the averag
Alika [10]

Answer:

The average price per square yard is $8.00

Step-by-step explanation:

From the question

849 yd² = $6,796

1 yd² = x

Cross Multiply

849 yd² × x = 1 yd² × $6,796

x = 1 yd² × $6,796/849yd²

x = $8.0047114252

Approximately = $8.00

Therefore, the average price per square yard is $8.00

How to find area of composite figures
Romashka [77]

Answer:

↓↓↓↓↓

Step-by-step explanation:

A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

What is the answer to a,b, and c? Thanks!
Katarina [22]

The area of a triangle can be calculated as half the product of base length and height. We want the area to be no greater than 10 in².

a) (1/2)(4)(2x-3) ≤ 10

b) 4x -6 ≤ 10 . . . . . simplify

... 4x ≤ 16 . . . . . . . .add 6

... x ≤ 4 . . . . . . . . . divide by the coefficient of x

c) The maximum value of (2x -3) in is (2·4 -3) in = 5 in.

The triangle should be no more than 5 in high to have an area less than 10 in².
