Answer:
Step-by-step explanation:
First we need to change the mixed numbers into improper fractions.
9 x 10 = 90 + 1 = 91/10
4 x 4 = 16 + 3 = 19/4
Now we need to get them into simplest terms. There is a few ways to do this, but I know that 10 x 2 = 20 and 4 x 5 = 20 so I will use 20.
Now we can subtract:
And that leaves us with our answer :D
Answer:
to my beliefs it is 18. I THINKKKKK I LIKE ALELI THINKS ITS 18
Answer:
972π or 3052.08 if π=3.14(remember to label the answer with your units)
Step-by-step explanation:
The formula for the volume of a sphere is 
π
. So, just plug the radius into the formula. <em> </em>in this case is 
which is 729. For, 
×729, the 3 and 729 cancel out to create 4×243 which is 972. Just add π to this and you get 972π. If π is 3.14 just multiple 972 and 3.14 to get 3052.08.
Answer:
Solution given:
- (sinx+cosx)^2-(sinx-cosx)^2
- sin²x+2sinxcosx+cos²x-(sin²x-2sinxcosx+cos²)
- 1+2sinxcosx-1+2sinxcosx
- 2(2sinxcosx)
- 2sin2x
Step-by-step explanation:
[note: sin²x+cos²x=1]
A negative multiply a positive = negative
