First find the area of the square (that is half made with the 11cm line). This is 9x11 which is 99. You have the 2 equal triangles to either side left. Because they are equal, you can work out that because it is 18cm - 9cm = 9cm and 9cm / 2 = 4.5cm, meaning that you have to do 4.5cm x 11cm to equal 49.5cm, but because it is a triangle you halve it, making 24.75cm (but because you are adding these together, you end up with 49.5cm anyway). Finally, you add thrm together : 99cm + 49.5cm which equals 148.5cm squared

juin [17]

Answer:

The area of the warehouse B is 1150 square feet.

Step-by-step explanation:

Let x, y are the width and length of the warehouse A, in inches. The areas of the each warehouse are described below:

A_{A} = x\cdot y (1)

A_{B} = \left(\frac{1}{2}\cdot x \right)\cdot \left(\frac{1}{3}\cdot y \right) (2)

Where:

A_{A} - Area of the warehouse A, in square inches.

A_{B} - Area of the warehouse B, in square inches.

If we know that A_{A} = 6900\,ft^{2}, then by (1) and (2) we have the following equation:

A_{B} = \frac{1}{6}\cdot A_{A}

A_{B} = 1150\,ft^{2}

The area of the warehouse B is 1150 square feet.

Find the inverse of the function y= -3/(x+4)
gregori [183]
The inverse for this operation would be to find the equation for "x" since it's the equation for "y." Inverse means reverse in direction or position. To find the inverse of "y = -3/(x+4) , you would need to start by using the order of operations. Here's where you start: 
y<span> = -3/(x+4)
</span>
Next, you want to get the (x+4) to the other side. Since it's being divided, multiply this number on both sides.

y = -3/(x+4) ⇒ (x+4)y = -3

Now, you need to get y on the opposite side. Divide both sides by y.

(x+4)y = -3 ⇒y÷ (x+4)y = -3 ÷ y

The y's cancel on the left, so you would have the equation: 

x+4 = -3/y

Now to get x by itself, subtract 4 from both sides.

x+4 = -3/y
  -4           -4

⇒x = -3/y -4 is your final answer.

A rectangle is 3 times as long as it is wide. if the area is 27 square feet, find its perimeter.
Marat540 [252]
W - a width
3w - a length
27 ft² - an area

Therefore:

w · 3w = 27
3w² = 27    |:3
w² = 9 → w = √9 → w = 3

3w = 3 · 3 = 9

width = 3
length = 9

The perimeter:

P = 2 · width + 2 · length

P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
