Answer:
a dice goes from 1-6
6+1=7
6+2=8
6+3=9
6+4=10
6+5=11
6+6=12
Of those possible choices, 5 are greater than or equal to 8. So the answer is 5/6.
mark brainiest please
3x² (6x² - 13x - 5) =
3x² (2x - 5) (2x+1) .
Answer:
5.
x + 2(x + 1) = 8 --> x = 2
y = 2 + 1 = 3
7.
3(9 + 2y) + 5y = 20 --> y = -7/11
x = 9 + 2(-7/11) = 85/11
9.
3(-1 - 2y) + 5y = -1 --> y = -2
x = -1 - 2(-2) = 3
I'm assuming there is probably a graph that goes with this problem so here is all the info I can give you with the four choices:
If it is -1/3, the line will go DOWN 1, over 3 (just count on the graph)
If it is 3, the line will go UP 3, over 1
If it is 1/3, the line will go UP 1, over 3
And if it it -3, it will go DOWN 3, over 1
(If the slope is 3 or -3, it would be quite steep compared to a slope of 1/3 or -1/3)
Hope that helps!
Answer:
3142.86 cubic cm
Step-by-step explanation:
volume of cone is given by formula
volume of cone = 1/3(area of base*height)
Given radius of base = 10cm
we know area of circle is given by
where r is radius of circle
thus area of base of cone is calculated below
![\pi 10^2\\=> 22/7 *100\\=> 314.2857](https://tex.z-dn.net/?f=%5Cpi%2010%5E2%5C%5C%3D%3E%2022%2F7%20%2A100%5C%5C%3D%3E%20314.2857)
area of base of cone is 314.2857 square cm
height = 30 cm
Thus volume of cone = 1/3* (area of base*height)
= 1/3(314.2857*30)
= 1/3 *9428.571 = 3142.857.
Thus, volume of cone is 3142.857 cubic cm.
volume of cone to the nearest hundredth is 3142.86 cubic cm
