I believe the answer is D.
The other answers would not make sense, because we do not know what kind of triangle we are looking at and none of the lines are parallel or perpendicular. Therefore we need two angles. C would not work, because if we knew A or B, we would know that the two angles are supplementary. If we had A, then B is 180-A, and vice versa. We do not need both A and B.
V=(1/3)hpir^2
lets say this is original, undoubled volume
so o=v=(1/3)hpir^2
so for new volume, or n, that is r to 2r, doubled radius
n=(1/3)hpi(2r)^2
n=(1/3)hpi4r^2
n=4((1/3)hpir^2)
remmember that o=(1/3)hpir^2
n=4(o)
it is 4 times the old one
Answer:
10
Step-by-step explanation:
y= 5x+105,y=15x+5 are the equations. Use them and you should get 10 weeks ($155)
Answer:
(x,y)(6,-5)
Step-by-step explanation:
given.x+y=1----(1)
2?+y=7----(11)
x+y=1
2x+y=7
x-2x+y-y=1-7
-x=-6
-x/-1=-6/-1
x=6
to substitute "x" from-----1
6+y=1
6-6+y=1-6
y=-5
•
. .(x,y)=(6,-5)
