I honestly have no idea. Geometry is my worst subject
All of them except for letter Z
Answer:
233.3 cubic units
Step-by-step explanation:
Volume of a pyramid
× base area × height
The volume of the pyramid



= 233.3 cubic units (rounded to the nearest tenth)
So for the dice to be 9 two die must be rolled. So we start with a 1/2 chance.
Then there are 36 possibilities to be rolled on a die (6*6) and there are 4/36 possibilities for the dice to roll a 9 (4+5, 5+4, 3+6, 6+3).
So we multiply 1/2 by 1/9 (4/36)- which equals 1/18.
So there is a 1/18 chance for the result of the dice rolled to be a 9.
I hope this helps!
Answer:
Keeping in mind the 'x' is in numerator, i got the answer to be 6.
Step-by-step explanation:
2/7x + 1/2x = 40/7 - 1/6x
2/7x + 1/2x + 1/6x = 40/7
2/7x + (3+1)/6x = 40/7
2/7x + 4/6x = 40/7
2/7x + 2/3x = 40/7
(2*3)+(2*7) / (7*3)x = 40/7
(6+14) / 21x = 40/7
20/21x = 40/7
20x = 40*21/7
20x = 40*3
x = 40*3 /20
x = 2*3
x=6
