75%; so if we say there are 100 people in this city that means 60 of them live in houses and 40 of them live in apartments. Of the 60 living in houses 20% of them (12% of total population; 60 x .20) own their own business and those in apartments (40) 10% of them (4% of total pop.; 40 x .10) have their own business. In total 16 of the 100 people have businesses and 12 of those people live in houses so 12/16 equals .75. We multiply this by 100 to get the percent so there’s 75% that a person who owns a business in this city will also live in a house.
Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15
The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows.
Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges.
Company B:8x5=40+15=$55 for 8 windows and service charges.
Company B would charge less for 8 windows.
Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service charges
My work for Company B: 6x5=30+15=$45 for 6 windows + service charges
$48-$45=$3
Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.
Sn = n(n+1) = 100(101) = 10100
23+23+16+16=78
78 is the perimeter:)
It would be C. (-1,-11/2)
Because the graph does not have a point on the x coordinate as -1 but on the y coordinate
