Answer:
$103
Step-by-step explanation:
Your living room is carpeted but you have allergies, and need to cover the 9 points floor with hardwood panel flooring. The panel flooring at Lowes cost $3.19 per square foot. (scale: 1m = 3.28 ft) Hint: Each unit contains 32.29 square feet. How much will it cost to purchase the flooring panels? (round to the nearest cent)
From the above question:
1 square foot = $3.19
32.29 square feet = x
Cross Mulitiply
x = 32.29 × $3.19
x = $103.0051
Approximately to the nearest cent = $103
Therefore, it will cost $103 to purchase the flooring panels
Cos(x)/(1+sin(x) + (1+sin(x))/cos(x)=
cos²(x)/cos(x)(1+sin(x)) + (1+sin(x))²/cos(x)(1+sin(x))=
cos²(x)+1+2sin(x)+sin²(x) /cos(x)(1+sin(x))=
2+2sin(x) / cos(x)(1+sin(x))=
2(1+sin(x)) / cos(x)(1+sin(x))=
2/cos(x)=
2*sec(x)

Answer:
A. $14.40 B. 12.80 C. 22.5
Step-by-step explanation:
It depends what the x is, lets say it is $16, then the discount price will be $20
