Hi, the answer is 1unit^3 :)

Formula:
Length × Breadth × Height

Tomtit [17]

Answer:

Pencils cost $0.12

Step-by-step explanation:

Set up a system of equations :D

let x represent pencils

let y represent pens

2x + 3y = 0.78

3x + 2y = 0.72

Because we are only interested in pencils we will solve for x first.

Isolate y in either equation, lets do the first one.

3y = 0.78 - 2x

y = (0.78 - 2x)/3

Simplify

y = 0.26 - (2x/3)

Now plug what we got into Y in the other equation

3x + 2 (0.26 - (2x/3)) = 0.72

solve by simplifying

3x + 0.52 - (4x/3) = 0.72

3x - (4x/3) = 0.20

9x/3 - 4x/3 = 0.20

lets change 0.2 into a fraction 2/10 simplified to 1/5

5x/3 = 1/5

25x/15 = 3/15

25x=3

x= 3/25 = 0.12

Consider a message signal m(t) with the spectrum shown in the following Figure. The message signal bandwidth W=1KHz, This signal

Andreas93 [3]

The lowest carrier frequency at which each modulated wave S(t) component may be uniquely defined by m(t) is

Fc,Fc+w,Fc-w =>1.5k,2.5k,0.5kHz

-Fc,-Fc+w,-Fc-w =>-1.5k,-0.5k,-2.5kHz

"-w,w -1kHz,1kHz" are the frequency components of the detector output in this case.

Fc,Fc+w,fc-w =>0.75k,1.75k,-0.25kHz

-Fc,-Fc+w,-Fc-w =>-0.75k,0.25k,-1.75kHz

This is further explained below.

<h3>What is the lowest carrier frequency for which each component of the modulated wave S(t) is uniquely determined by m(t)?</h3>

For a modulated wave with frequency components, the equation looks like this:

Fc,Fc+w,Fc-w =>1.5k,2.5k,0.5kHz

-Fc,-Fc+w,-Fc-w =>-1.5k,-0.5k,-2.5kHz

"-w,w -1kHz,1kHz" are the frequency components of the detector output in this case.

In conclusion, we may state that the modulated wave has frequency components as well.

Fc,Fc+w,fc-w =>0.75k,1.75k,-0.25kHz

-Fc,-Fc+w,-Fc-w =>-0.75k,0.25k,-1.75kHz

Calculate the approximate area of the shape to the nearest cm2.

emmasim [6.3K]

This is very simple. So you use two formulas:

Rectangle: Length • Width

Semicircle: Area = $\frac{\pi r^2}{2}$

With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.

Area of semicircle: ≈ 0.25

Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6

For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,

Round to nearest tenth: 0.9

Round to nearest hundredths: 0.85
