In the seating for a concert, the first row has 10 chairs. Every row after that has 2 more chairs. 7. What is the explicit formula that models this situation? 8. How many chairs are in row 20?
9514 1404 393
Answer:
7. c(n) = 10 +2(n -1)
8. c(20) = 48
Step-by-step explanation:
7. Your arithmetic sequence has first term a1=10 and constant difference d=2. The explicit formula for terms of an arithmetic sequence is ...
an = a1 +d(n -1)
If we use c(n) as the function name for the function giving the number of chairs in row n, then we can fill in the numbers we know to get ...
c(n) = 10 + 2(n -1)
__
8. Evaluating the function when n=20, we find ...
c(20) = 10 +2(10-1) = 10 +2·19 = 10 +38
c(20) = 48
There are 48 chairs in row 20.
Can someone help me calculate angles? P2
Answer:85
Step-by-step explanation: In this problem you are trying to find the missing angle of a line. In a line all angles have to add up to 180 so what you wanna do first is add 55 and 40 which gives you 95. Next, you wanna subtract 95 from 180 which will give you 85. Now you know the missing angle.

HELP ASAP A furniture manufacturer must pay $16.91 to make a certain kind of chair, which it can sell for $55.75. If the manufacturer has starting overhead costs of $18,340, not including production costs, how many chairs must it sell to realize a profit of $24,850, to the nearest chair?
a. 1,112
b. 918
c. 775
d. 640
(10 points and brainliest if the answer is right)
Answer:
A. 1,112
Step-by-step explanation:
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Option A is the correct answer.
What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's start by finding the profit per chair:
So,
Profit per chair = Selling price - Production cost
= $55.75 - $16.91
= $38.84
Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:
Profit = Profit per chair x Number of chairs sold - Overhead costs
$24,850 = $38.84x - $18,340
$43,190 = $38.84x
x = 1,112.49
Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Therefore,
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

If bricks are each 3 inches × 4 inches × 8 inches, how many bricks can be fit into a space which is 1 foot × 4 feet × 8 feet?
A 1 to 250
B 251 to 500
C 501 to 750
D 751 to 1000
E >1000
Answer:
The correct option is B.
Step-by-step explanation:
Consider the provided information.
The dimensions of bricks are in inches so convert foot into inches.
1 foot = 12 in
4 feet = 48 in
8 feet = 96 in
To calculate the number of bricks that fit into space we divide the space's volume by the volume of 1 brick.
[tex]\text{Number of bricks in space}=\dfrac{12\times 48 \times96}{3\times 4 \times8}[/tex]
[tex]\text{Number of bricks in space}=576[/tex]
Hence, 576 bricks can be fit into a space.
Therefore the correct option is B.

Given:
In triangle ABC, Q is the centroid and FQ=9.
To find:
The length of FC and QC.
Solution:
We know that, centroid is the intersection point of medians of a triangle and medians divide teach other in 2:1. So, centroid divided each median in 2:1.
CF is a median and Q is the centroid. So,
[tex]QC:FQ=2:1[/tex]
Let the length of QC and FQ are 2x and x respectively.
We have, FQ=9.
[tex]x=9[/tex]
Now,
[tex]QC=2x[/tex]
[tex]QC=2(9)[/tex]
[tex]QC=18[/tex]
And,
[tex]FC=FQ+QC[/tex]
[tex]FC=9+18[/tex]
[tex]FC=27[/tex]
Therefore, the length of FC is 27 units and length of QC is 18 units.
