Yes, because centimeters are smaller than inches, making you need more of them to equal an inch.

Find the area of the shape shown below.

Tamiku [17]

Answer:

28 square units.

Step-by-step explanation:

Let us divide the shape into two rectangles and a right triangle. The resulting composite figure is attached.

As we see in the figure the area $A_T$ of the triangle is

$A_T= \frac{1}{2} (2)(4)=4\: units^2$ .

The area $A_{r1}$ of the bigger rectangle is (it's actually a square )

$A_{r1}=4*4=16\:units^2$ ,

and the area of the smaller rectangle is

$4*2 =8\:units^2$ .

Therefore, the total area $A_{tot}$ of the shape is

$A_{tot}= A_T+A_{r1}+A_{r2}$

$A_{tot}= 4\:units^2+16\:units^2+8\:units^2$

$\boxed{A_{tot}=28 \:units^2}$

Determine the value(s) of k such that the system of linear equations has the indicated number of solutions. (Enter your answers

Ratling [72]

Answer:

k=3

Step-by-step explanation:

The given system of equations are

$9x+ky=24$

$kx+y=8$

We need to find the value of k if the given system of equation have infinite number of solutions.

If two equations $a_1x+b_1y+c_1=0$ and $a_2x+b_2y+c_2=0$ have infinite number of solutions, then

$\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$

Using this we get

$\dfrac{9}{k}=\dfrac{k}{1}=\dfrac{-24}{-8}$

$\dfrac{9}{k}=\dfrac{k}{1}=3$

$\dfrac{k}{1}=3$

$k=3$

Therefore, the value of k is 3.
