Answer:
9 + 7n - 3 ;
61 ;
Step-by-step explanation:
Let the number = n
9 + 7*n - 3
Hence, the expression is :
`9 + 7n - 3
If the number,n = 8
The value of the expression becomes :
9 + 7(8) - 3
8 + 56 - 3
= 61
9 ft tall and 4 ft wide 9(2)+4=22 and 4(2)+1=9
2/3 because you flip 3 coins and you want to get al least 2 heads!
Answer:
284/3 πx³
Step-by-step explanation:
Volume of a cylinder is expressed as shown:
V = πr²h
r is the radius of the cylinder
r = diameter/2
r = 8x/2
r = 4x
Height of the cylinder = 6x
Volume of the roll with out the hole
V = π(4x)²(6x)
V = 16x²π(6x)
V = 96πx³
The hole in the middle will be a solid sphere with diameter 2x (radius will be x)
Volume of the hole = 4/3πr³
Volume if the hole = 4/3πx³
Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole
= 96πx³ - 4/3πx³
= (96-4/3)πx³
= 284/3 πx³
Answer: A, C and E.
Step-by-step explanation:
The expressions 1/2 + 3c + 4/5 is thesame as writing 3c + 1/2 + 4/5, 1/2 + 4/5 + 3c, 4/5 + 1/2 + 3c, 3c + 1/2 + 4/5.
In all the expressions written above, the only thing that can be seen is just that the position of the numbers were alternated.
Therefore, based on the options given, the answer will be A, C, and E.
