Answer:
Step-by-step explanation:
The ratio of boys to girls is 12 to 16, 12:16 or 12/16 (all different ways this can be written). The fraction form 12/16 can be reduced by dividing by the greatest common factor. Both 12 and 16 are divisible by 4, so the reduced fraction is 12/4 over 16/4 = 3/4. In other words, there are 3 boys for every 4 girls in the class.
Answer:
Step-by-step explanation:
1. Area of the composite figure = Area of the sector + Area of rectangle
Area of sector = (θ/ 360) x 
From the figure,
θ = 30, and r = 65
Area of sector = 
x 
x 65 x 65
= 1 1065.55
Area of rectangle = length x width
= 65 x 4
= 260
Area of the composite figure = 1 1065.55 + 260
= 11325.55
Area of the composite figure is 11326 .

Answer:
2 Years, 9 Months, 3 Weeks, 5 Days and 1 Hour
Step-by-step explanation:
2,798.5 miles from L.A. to New York, an ant travels at 3 inches a second, we multiply 3 by 60 to get 120 inches a minute convert that into feet to get 10 feet, now multiply that by another 60 to get 600 feet an hour now multiply 600 by 24 to get 14,400 feet a day convert that into miles to get 2.72 miles a day now take 2.72 miles and divide that by the distance between the 2 cities to get about 1030 days, now if we put that into years, months, weeks, days and hours we get 2 Years, 9 Months, 3 Weeks, 5 Days and 1 Hour
