Answer:

n ≥ − the quantity 3 times c minus 9 all over p

Step-by-step explanation:

To solve inequalities you should use the same method as to solve equalities.

1. First write down the inequality:

-np-6\leq 3(c-5)

2. Solve the parentheses:

-np-6\leq 3c-15

3. Pass the independent numbers to the right side of the inequality with opposite sign and do the mathematical operations:

-np\leq 3c-15+6\\\\-np\leq 3c-9

4. Pass the p with the minus sign to the right side of the inequality, as p has the minus sign, the direction of the inequality changes:

n\geq -(\frac{3c-9}{p})

Which expression represents the volume, in cubic
muminat

Given:

The composite figure.

To find:

The volume of the given composite figure.

Solution:

Given composite figure contains a cuboid and a pyramid.

Length, breadth and height of the cuboid are 8, 6 and 4 respectively.

Volume of a cuboid is

V_1=length\times breadth\times height

V_1=(8)(6)(4)

Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.

Height of pyramid = 10 - 4 = 6

Volume of a pyramid is

V_2=\dfrac{1}{3}\times length\times breadth\times height

V_2=(\dfrac{1}{3})(8)(6)(6)

The volume of composite figure is

V=V_1+V_2

V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)

It can be written as

V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)

Therefore, the correct option is A.
