Answer:
Total surface area of the pyramid = 
Step-by-step explanation:
To find the surface area of the triangular- based pyramid, we will use the formula:
Surface area = Area of base + Area of the three faces
Area of base of the pyramid = Area of equilateral triangle = 

Area of the slant faces of the pyramid is 

Since there are 3 slant surfaces the total surface area of the pyramid =
If 5/11 are girls, then 6/11 are boys (the total has to be 11/11, which equals 1).
Multiply the fraction of boys by the total number of students.
(6/11)*1551 = 846
Therefore, 846 of the students in the school are boys.
Answer:
Step-by-step explanation:
So, volume is always cubed since you have l x w x h.
A cubic ft is 12 in x 12 in x 12 in = 1728 in3. If we assumed that the aquarium has a volume of around 35328.78 in squared. Hence,
35328.78/1728 = 20.44
20.44 x 7.48 = 152.89
About 153 gallons
Noted that the water was used at the rate of 56 gallons per minute.
56 gallons -------- 1 minute
153 gallons --------- x minute (s)
56gallon × Xminutes = 153 gallons × 1 minute
X = 153/56
X = 2.7321 minutes
Hence, it will take 2.7321 minutes to drain the tower
Yes, it's y= 1/2x because it's 1/2 miles (y) per x weeks
