Leonhard wants to place a triangular-based cabinet in the corner of his rectangle-shaped living room. The triangular base has a
Illusion [34]

Answer: The answer is (A)~~x=\dfrac{-7+\sqrt{193}}{4}.


Step-by-step explanation: Given that Leonhard wants to place a triangular based cabinet in the corner of his room which is rectangular in shape.

The base and height of the triangular cabinet are

b=(2x+3)~\textup{feet},\\\\h=(3x+6)~\textup{feet}.

Therefore, area of the triangular cabinet is given by

a=\dfrac{1}{2}\times b\times h=\dfrac{1}{2}(2x+3)(3x+6)~\textup{sq. feet.}

Now, the length and breadth of the rectangular room are 30 feet and 20 feet respectively. Therefore, the area of the room is given by

A=30\times 20=600~\textup{sq. feet.}

According to the question,

a=6\%\times A\\\\\Rightarrow \dfrac{1}{2}(2x+3)(3x+6)=\dfrac{6}{100}\times 600\\\\\Rightarrow (2x+3)(3x+6)=24\times 3\\\\\Rightarrow (2x+3)(x+2)=24\\\\\Rightarrow 2x^2+7x-18=0\\\\\Rightarrow x=\dfrac{-7\pm\sqrt{7^2-4\times 2\times(-18)}}{2\times 2}\\\\\\\Rightarrow x=\dfrac{-7\pm\sqrt{193}}{4}.

Since the length of something cannot be negative, so the value of 'x' is

x=\dfrac{-7+\sqrt{193}}{4},

because if we take the other value of 'x', the values of (2x+3) and (3x+6) will become negative which is not possible.

Thus, (A) is the correct option.

A crane lifts a pallet of concrete blocks 7ft from the back of a truck. The truck drives away and the crane lowers the pallet 11
Dmitrij [34]

Answer:

The position of the concrete relative to its initial position is 4ft behind its initial position

Step-by-step explanation:

Let us analyze the problem following the sequence of events.

First of all, the crane is initially 7 ft from the back of the truck.

Once the truck drives away, the crane lowers the concrete at 11 ft away from the back of the truck.

To get this distance relative to the initial position, we have to subtract the initial position from the final position of the concrete.

This will  be

11ft - 7ft = 4 ft

The position of the concrete relative to its initial position is 4ft behind its initial position

This number is 0.02 more than 5 and 5 tenths
vampirchik [111]
That number would be 5.52
This is because 5 and 5/10 is the same as 5 and 1/2
5 and 1/5 in decimal form is 5.50
Then we will add 0.02
That will make the answer 5.52
