inessss [21]

Answer:

The required inequality is: 6\leq x

Step-by-step explanation:

Consider the provided information.

Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money, but he must work fewer than 16 hours this week.

Let the number of hours Gurnaz work is represented by x.

Gurnaz will need to work for at least six hours to save enough money,

That means he can work 6 or more than 6 hours,

x\geq 6

He must work fewer than 16 hours this week. That means the value of x should be less than 16.

x

Thus, the required inequality is: 6\leq x

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ or ≥ and use a open circle to represent < or >.

The value of x is greater than or equal to 6 also the value of x is less than 16. The required graph is shown below.

A boiler room has the shape of a rectangular prism. The area of the floor of the room is 112 square feet. The length of the room
Naddik [55]

Answer:

Length = 16 feet.

Width = 7 feet

Height = 8 feet

Volume = 896 cubic feet.

Step-by-step explanation:

There is a rectangular prism boiler room. 112 square feet is the floor area of the room.

Let the length of the room is L feet and width is W feet.

So, LW = 112 ...... (1)

Now, given that L = 2 + 2W ........ (2) , hence, from equation (1) we get  

(2 + 2W)W = 112

⇒ 2w + 2w² = 112

⇒ W² + W - 56 = 0

⇒ (W +8)(W - 7) = 0

⇒ W = 7 feet. {Neglecting the negative root as W can not be negative}

Hence, from equation (2) we get L = 2W + 2 = 16 feet.

Now, 1 foot more than the width is the height H.

Hence, H = 7 + 1 = 8 feet.

Therefore, the volume of the room is, V = LWH = 16 × 7 × 8 = 896 cubic feet. (Answer)
