There's no cube shown but we can guess the diagonal is the long diagonal.
In a rectangular parallelpiped (aka a box) with dimensions a × b × c the long diagonal x satifies a 3D version of the Pythagorean Theorem,
x² = a² + b² + c²
In a cube a=b=c
x² = 3a²
x = a√3
Answer: 7√3
Answer:
x = 12
y = -2
Step-by-step explanation:
In a parallelogram, the sides opposite each other are equal.
Hence: PQ = SR and PS = QR
2x + 12 = 4x - 12
Rearrange to make x's on one side and the numbers on the other
4x - 2x = 12 + 12
2x = 24
x = 12
____________
y + 25 = 6y + 35
Rearrange to make y's on one side and the numbers on the other
6y - y = 25 - 35
5y = -10
y = -2
Answer:
1.5 hours.
Step-by-step explanation:
Football practice is 3 hours long, divided into 2 equal parts.
3/2=1.5.
So, 1.5 hours or 1 hour and 30 minutes is spent doing warm up exercises and the other 1 hour and 30 minutes is spent practicing football plays.
