The length of a deck is 4 times its width. if the perimeter is 30 feet what is the area

Find the surface area of the cube shown.<br> (_________) square centimeters

Step2247 [10]

Answer:

The answer is: 181.5 square centimeters.

Step-by-step explanation:

The cube has six faces, and each face is a square with sides of length 5.5, so the area of one of this faces is $5.5^2=30.25$ , adding the six faces, we get the answer: $A=6\times 30.25=181.5$

Please choose all irational thx ^_^

Answer:

Here is a note to help you: Most numbers are rational numbers. Here is how you know when a number is rational or not [especially if its a decimal].

Rational:

- Decimals are usually rational. Rational decimals my look like this:

1) 0.25

2) 0.333333333...

3) 0.234234234234234234...

The following above are rational because they either: terminate or repeat. That being said, 1) terminates, and 2) and 3) repeat because the pattern of 2) is just 3's, and the pattern of 3) is 0.234 over and over again.

Irrational:

- Irrational numbers are numbers that don't repeat, and don't terminate. The next examples are irrational:

1) 0.234536718092343...

2) 8.123456789023452574794832468...

3) 1723456.4356784794954233690422...

- They go on forever and ever, and don't have a pattern/terminate like rational numbers.

Now that you've got that in the bag, its time for your answers!

Step-by-step explanation:

A) rational --> It has a pattern, but does not terminate

B) rational --> It terminates

C) irrational --> it does not have a pattern, even if it does terminate

D) rational --> when you solve it, the answer is 2, and 2 is rational

E) irrational --> it does not have a pattern, but does terminate

I hope I helped you! This took forever, but it was worth it! :D

Y = (x) =(1/8)^x<br> Find f(x) when X =<br> (1/3)<br> Round your answer to the nearest thousandth.

vlada-n [284]

Answer:

1/2.

Step-by-step explanation:

f(x) = (1/8)^x

when x = 1/3

f(x) = (1/8)^1/3

f(x) = ∛(1/8)

f(x) = 1 / ∛8

f(x) = 1/2.

What is the vertex of the graph of y = −1(x − 2)2 + 3

Alona [7]

$Vertex: \ (2,3)$

<h2>Explanation:</h2>

The vertex form of the equation of a parabola is given by the following form:

$f(x)=a(x-h)^2+k \\ \\ Where: \\ \\ a:Leading \ Coefficient \\ \\ (h,k):Vertex \ of \ the \ parabola$

In this exercise, we have the following equation:

$y=-(x-2)^2+3$

From here, we can conclude that:

$Leading \ coefficient: \ -1 \\ \\ Vertex: \ (2,3)$

Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.

What’s 6-1/3x=-1 in two step equation???

swat32

Answer:

x=21

Step-by-step explanation:

subtract 6 from both sides get -1/3x=-7

multiply -1/3 or -1/3 as decimal times -7

and get x=21

If brainiest is earned its greatly appreciated. :)
