Answer:
The volume of cube C is
Step-by-step explanation:
step 1
Find the diameter of sphere B
we know that
When a cube is inscribed in a sphere, the long diagonal of the cube is a diameter of the sphere
Let
L ----> the length side of cube A
d ----> the diagonal of the base of cube A
D ---> the long diagonal of cube A
Find the diagonal of the base of cube A
Applying the Pythagorean Theorem
we have
substitute
Find the long diagonal of cube A
Applying the Pythagorean Theorem
substitute
step 2
we know that
If sphere B is inscribed in cube C, then the length side of cube C is equal to the diameter of sphere B
Let
c ----> the length side of cube C
we have that
The volume of cube C is equal to
substitute
The chance that both come up red is 2/3.
<u>Step-by-step explanation</u>:
First regular die :
The total outcomes are {1,2,3,4,5,6} = 6
Painted red are odd numbers {1,3,5} = 3
Second regular die :
The total outcomes are {1,2,3,4,5,6} = 6
Painted red are one less than perfect square which is 4-1 is {3} = 1
- Probability (both red) = (red in 1st die / total outcome) + (red in 2nd die / total outcome)
P(both red) = 3/6 + 1/6
⇒ 4/6
⇒ 2/3
This can be solve by money balance , subtract the money that
goes out in your hand and add what goes in. since the man steals 100 and buys
worth 70
<span>Money lose = -100 + 100 – 30 – 70 = $ 100 is his total lose. But
if speaking only of cash money not including what he bought the owner lose only
$30 </span>
Square both sides of the inequality.
x > 16
E, F are numbers greater than 16.
