Answer:
(A)29 cubic inch
Step-by-step explanation:
Diameter of the Cone =4 Inches
Height of the Cone =7 Inches
Volume of a Cone 
First, we determine the radius, r.
Radius=Diameter/2=4/2=2 Inches
Therefore:
Volume of one paper cone 
=29.32 cubic inch
=29 cubic inch (to the nearest cubic inch.)
Answer:
2/15
Step-by-step explanation:
There is a 4/10 probability that she chooses blue the first time, but the second time it is a 3/9 chance because she didn't put the marble back so there are 9 marbles in total, 3 blue ones.
4/10 x 3/9 = 2/5 x 1/3 = 2/15
I hope this helps :)
Edit: Messed up the multiplication, whoops!
Answer:
C) 3
Step-by-step explanation:
2x-y=3
-4x+2y=-6
4x+3y=11
-4x+2y=-6
4x+3y=11
5y=5
<u>y=1</u>
2x-y=3
2x-1=3
2x=4
<u>x=2</u>
2+1=<em><u>3</u></em>
This doesn’t make any sense
