Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
Width of key in student calculator = 14 millimeter (1.4 cm)
Width of key in demonstration calculator = 2.8 cm
Thus, the demonstration calculator's dimensions are twice that of students' (in cm)
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
Answer: A= (-1, 1) B= (1, 2) C= (0, 1)
The changes in coordinate that undergo diagonal line reflection would be switching between the x and y coordinate. In y=-x diagonal line, the change will also apply minus. You are given the reflected vertice and asked the real triangle coordinate. Then you just need to apply the transformation change. The coordinate would be:
Ax= A'y * -1= 1*-1 = -1
Ay= A'x * -1= -1 * -1 = 1
A= (-1, 1)
Bx= B'y * -1= -1*-1 = 1
By= B'x * -1= -2 * -1 = 2
B= (1, 2)
Cx= C'y * -1= 0*-1 = 0
Cy= C'x * -1= -1 * -1 = 1
C= (0, 1)

Step-by-step explanation:
Answer:
Number of student tickets = 325
Number of adult tickets = 404
Step-by-step explanation:
Let,
x be the number of student tickets
y be the number of adult tickets
According to given statement;
x+y=729 Eqn 1
3x+5y=2995 Eqn 2
Multiplying Eqn 1 by 3
3(x+y=729)
3x+3y=2187 Eqn 3
Subtracting Eqn 3 from Eqn 2
(3x+5y)-(3x+3y)=2995-2187
3x+5y-3x-3y=808
2y=808
Dividing both sides by 2
Putting y=404 in Eqn 1
x+404=729
x=729-404
x=325
Hence,
Number of student tickets = 325
Number of adult tickets = 404
