Answer:
1350 mm²
Step-by-step explanation:
The area of each square face is the square of the edge length:
... face area = (15 mm)² = 225 mm²
There are 6 square faces on a cube, to the total surface area is 6 times that of one face:
... cube area = 6 × face area = 6×225 mm² = 1350 mm²
Hopefully this helps, x=35 because all angles has of a triangle has to add up to 180
Answer:
Step-by-step explanation:
It is 191 remainder 3
We randomly select one card from 52, so there are 52 outcomes and:
![\overline{\overline{\Omega}}=52](https://tex.z-dn.net/?f=%5Coverline%7B%5Coverline%7B%5COmega%7D%7D%3D52)
We also know, that there are
![4\cdot3=12](https://tex.z-dn.net/?f=4%5Ccdot3%3D12)
face cards in a standard deck (
![\overline{\overline{F}}=12](https://tex.z-dn.net/?f=%5Coverline%7B%5Coverline%7BF%7D%7D%3D12)
) and only three of them are diamonds, so
![\overline{\overline{D\cap F}}=3](https://tex.z-dn.net/?f=%5Coverline%7B%5Coverline%7BD%5Ccap%20F%7D%7D%3D3)
With this informations, we can calculate our probability:
