3:5...added = 8
3/8(40 = 120/8 = 15 inches
5/8(40) = 200/8 = 25 inches
shorter piece is 15 inches
Let x represent lower level tickets that cost $77
Let y represent upper level tickets that cost $99
Cost equation: 77x + 99y = 247,071
Tickets equation: x + y = 2615
Using the elimination method, multiply the second equation by -77:
77x + 99y = 247,071
-77x - 77y = -201,355
--> 22y = 45,716
--> y = 2,078
Now plug "y" into either equation and solve for "x". I chose the Tickets equation. x + y = 2615 → x = 2615 - y → x = 2615 - 2078 → x = 537
Answer: lower level = 537 tickets, upper level = 2078 tickets.
Total cost of painting 225 cm² will be:
Cost=(total area)×(cost per cm²)
area=225 cm²
cost per cm²=$0.12
thus the total cost will be:
Cost=0.12×225=$27
Answer: $27
Answer:
The answer to your question is letter D
Step-by-step explanation:
Data
P1 (3, 10)
P2 (-1, 6)
Process
1.- Calculate the midpoints
Xm = (x1 + x2)/2
Ym = (y1 + y2)/2
x1 = 3 y1 = 10
x2 = -1 y2 = 6
Xm = (3 - 1)/2
= 2/2
= 1
Ym = (10 + 6)/2
= 16/2
= 8
2.- Write the coordinates of the center
C = (1, 8)
