Answer:

7.92 cm^3

Step-by-step explanation:

To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

katrin2010 [14]

As you know, to get the inverse of any expression, we start off by switching the variables about and then solving for "y",

$\bf \stackrel{f(x)}{y}=\cfrac{1}{2}x+4\qquad \qquad \stackrel{inverse}{\underline{x}=\cfrac{1}{2}\underline{y}+4}\implies x-4=\cfrac{1}{2}y
\\\\\\
2x-8=\stackrel{f^{-1}(x)}{y}
\\\\\\
f^{-1}(4)=2(4)-8\implies f^{-1}(4)=0$

How do I find the perimeter of a polygon?

noname [10]

Add up the lengths of the several sides of the polygon.

Examples: The perimeter of a triangle is the sum of the lengths of the 3 sides.

The perimeter of a hexagon is the sum of the lengths of the 6 sides.

And so on.

I highly recommend drawing any polygon whose perimeter you wish to calculate.

lana66690 [7]

Answer: - 32

Step-by-step explanation:

-8 + (-24)

Infront of the Positive is a one.

-8 +1 (-24)

If we follow order of operations which is parentheses, exponents, multiply divide, add, and subtract, we can see we need to multiply/ distribute first. And a positive times a negative is a negative.

-8 -24

Now we put the two numbers together.

-32

This is the answer

What decimal is equivalent to 4/5 + 0.05

UNO [17]

To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:-

4/5
4 ÷ 5 = 0.8

Now lets substitute 0.8 for 4/5 and then add.

4/5 + 0.05
0.8 + 0.05 = 0.85

CHECK OUR WORK:-

0.85 - 0.8 = 0.05
We were RIGHT!!

So, the decimal 0.85 is equivalent to 4/5 + 0.05.

Hope I helped ya!! xD
