To draw a heart, one would be choosing 1 card of 13 possible hearts, and 0 from the remaining 39 non-hearts. With respect to the entire deck, one would be choosing 1 card from 52 total cards. So the probability of drawing a heart is

When Michelle replaces the card, the deck returns the normal, so the probability of drawing any card from a given suit is the same, 

. In other words, drawing a spade is independent of having drawn the heart first.
So the probability of drawing a heart, replacing it, then drawing a spade is 

.
 
        
        
        
Hello!
The formula for the volume of a sphere is  ³.
³.
Let's plug in our radius.

As we are not looking for an exact answer,we can look for an answer in terms of pi. Maybe we could multiply our fraction by 1,000.

Therefore, our answer is D.
I hope this helps!

Answer:
A
Step-by-step explanation:
Find AB using the Law of Sine:

Thus:

Multiply both sides by sin(40)


AB = 31.0056916 ≈ 31.0 cm (nearest tenth)
