This is not my level but i can try to solve it
Answer:
X = 9 and Y = 8
Step-by-step explanation:
We are to find the midpoint of the coordinates (13,15) and (5,1).
Using the midpoint formula;
M(X, Y) = [(x1+x2)/2, (y1+y2)/2]
X = (x1+x2)/2
Y = (y1+y2)/2
From the coordinates, x1 = 13, y1 = 15, x2 = 5 and y2 = 1
X = 13+5/2
X = 18/2
X = 9
Similarly;
Y = 15+1/2
Y = 16/2
Y = 8
Hence The Tourist Information Center is located at point X = 9 and Y = 8
Answer:
T.A = 54 + 9/2 √3
Step-by-step explanation:
∵ The figure is triangular prism
∴ T.A = perimeter of the base × height + 2 × area of the base
∵ The base is an equilateral Δ with side length 3"
∴ The perimeter of the base = 3 × 3 = 9 inches
∴ The area of the base = 1/4 S² √3 = 1/4 (3)²√3 = 9/4 √3 inches²
∵ The length of the height of the prism = 6"
∴ T.A = 9 × 6 + 2 × 9/4 √3 = 54 + 9/2 √3
∴ T.A = 54 + 9/2 √3 inches²
0.8(1600) = 1280
1280 visitors went to see the show
Answer: Hence, the correct size of boys group is 5 and girls is 6.
Step-by-step explanation:
Since we have given that
Number of boys = 60
Number of girls = 72
We need to divide the students into gender specific groups of the largest possible size.
For this we will find "HCF of 60 and 72" which is equal to "12".
So, the correct size of each group is 12 in which number of boys would be 
Number of girls would be 
Hence, the correct size of boys group is 5 and girls is 6.
