Answer:
Step-by-step explanation:
So the Dimensions are:
Height: 300cm
Length: 300cm
Width: 2cm
SA = 2(H*L)+2(H*W)+2(L*W)
= 180000 + 1200 + 1200
= 182400 
OR 18.24
Answer:
V=97.08
Step-by-step explanation:
The formula for the volume of a cone is V= 1/3 pi (r)^2 (h)
To find the radius divide the diameter by 2. 6/2=3
Plugin: V=1/3 pi(3)^2(10.3)=97.08
That's false. Take the numbers 1, 3, and 5.
Let a = 1, b = 3, and c = 5.
ab + bc = ac
3 + 15 = 5
18 ≠ 5
Since 18 does not equal 5, this is false. If you were to use the distributive property on ab + bc = ac, you would get
b(a+c) = ac, which doesn't even make sense.
Have a nice day! :)

Answer:
255
Step-by-step explanation:
If the sum of digits is 12, the number is divisible by 3. If the number ends in 0 or 5, it is divisible by 5. So, we're looking for ...
2x0 . . . where x is a digit and 2+x+0 = 12 . . . . . . not possible
2x5 . . . where x is a digit and 2+x+5 = 12 . . . . true for x=5
The number is 255.
Answer:
x = 15
Step-by-step explanation:
y = family members = 7
x = cost of ticket
7x + 6y = 147
Substitute 7 for y:
7x + 6(7) = 147
7x + 42 = 147
Subtract 42 on both sides:
7x + 42 = 147
- 42 -42
7x = 105
Divide both sides by 7:
7x = 105
x = 15
