The total number of marbles is 15. The probability of picking a blue marble is 6/15. After putting the marble back, the probability of picking another blue marble is probably 1/9.
Answer: the probability of picking two blue marbles in a row is 1/9.
Step-by-step explanation:
The area of a triangle is 1/2×width×length. Volume of a triangular prism is 1/2×width×length×height.
Fill in and we get 1/2×10×length×4=140. length=(140×2)/(10×4)=280/40=7. So you're right.
Answer:
a) 16 in³
Step-by-step explanation:
Vol (cyl) = πr²h = 54
Vol (cone) = πr²h/3
54/3 = 16
For number 39: 7 x 18 x 14 = 1764.
Your answer for #39 = A) 1764.
For number 41: W+W+H+H Or.. W+H+W+H
4 x 2 =8 12 x 2= 24 8 + 24 = 32.
#39 = 1746
#41 = 32
