The surface area of the net of cube is 726 sq cm

The surface area of the cube is 484 sq cm

Step-by-step explanation:

Here we need to find out the surface area of net of a cube and a cube

Given,

Each side of the cube is 11 cm

The net of a cube consists of 6 squares.

Formula

The surface area of the net of the cube = 6 X ( area of each square)

= 6 X ( 11 X 11) sq cm

= 726 sq cm

Now, the surface area of a cube = lateral surface area of the cube

Formula

The lateral surface area of the cube = 4 X $side^{2}$

= 4 X $11^{2}$ sq cm

= 484 sq cm

Hence the surface area of the net of a cube and only a cube is different.

If one letter is chosen at random from the word refuse what is the probability that the letter chosen will be an e

mrs_skeptik [129]

Answer: 1/3

Step-by-step explanation: The probability is given by the number of times the event could happen (in this case get an "e"), over the number of all the possibilities (in this case, the six letters of the word)

Therefore, probability $\frac{letter_e}{all letter}=\frac{2}{6} =\frac{1}{3}$

If f(x)=1/6x+12, then f^-1(x)=<br> PLEASE HELP

Finger [1]

$f(x)=\dfrac{1}{6}x+12\to y=\dfrac{1}{6}x+12$

Change x to y, and y to x.

$x=\dfrac{1}{6}y+12$

solve for y:

$\dfrac{1}{6}y+12=x\ \ \ |-12\\\\\dfrac{1}{6}y=x-12\ \ \ \ |\cdot6\\\\y=6x-72$

Your answer is:

$f^{-1}(x)=6x-72$

X^2 + y^2 = 8<br> X-y=0<br> Select all of the following that are solutions to the system shown

ludmilkaskok [199]

X^2 + y^2 = 8
X-y=0 so x = y

replace x = y into X^2 + y^2 = 8

y^2 + y^2 = 8

2y^2 = 8

y^2 = 8/2

y^2 = 4

y = - 2 and y = 2

because x = y

so x = - 2 and x = 2

solutions:

x= - 2 and x = + 2

y= - 2 and y = + 2
