Calculate 48 x 3/8 choose the numbers to complete the equation

Answer:

The fraction of the pencils that are red is 4/10. The fraction of the pencils that are black is 6/10.

Step-by-step explanation:

[I can't draw you a model but I reccomend that when you do, you seperate it into 10 pieces and mark 4 as red pencils and 6 as black pencils. You could also simplify 4/10 to 2/5 and 6/10 to 3/5, but instead you'd seperate the model into 5 pieces and mark 2 as red pencils and 3 as black pencils.]

First, let's add this up so we have our denominator.

4 + 6 = 10.

Now that we know that the denominator is 10, we apply it to the question.

The box has 4/10 red pencils and 6/10 black pencils.

The box has 4/10 red pencils and 6/10 black pencils.If you were to simplify, it'd be 2/5 red pencils and 3/5 black pencils.

Answer:

45 g de oxido de hierro (III) liberarán 18.9 L de CO₂

Step-by-step explanation:

La reaccion quimica es la siguiente:

Fe₂O₃ (s) + 3CO (g)  →  2Fe (s) + 3CO₂ (g)

1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.

Pasamos la masa de F₂O₃ a moles:

159.6 g . 1 mol /159.7g = 1 mol de oxido

Entonces, aplicamos la regla de tres:

1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.

Ahora calculamos los nuevos moles:

45g . 1 mol /159.7 g = 0.282 moles

Aplicamos la regla de tres:

Si un mol de oxido produce 3 moles de CO₂

0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂

Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:

Si 3 moles de CO₂ ocupan 67.2 litros

0.845 moles ocuparan (0.845  . 67.2/  3 ) =  18.9 litros

Answer: I cant see that last answer but I think it would be that one

Step-by-step explanation:

(Redirected from Obtuse triangle) An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

Hope this helps if it did pls mark me brainiest

none of them

Step-by-step explanation:

an obtuse angle is called to an wngle which is more than 90° and less than 180°

none of these have such an angle

Answer:

a. 16

b. 117

Step-by-step explanation:

a. 6+10=16

b. 120-3=117

Answer:

a=44, b= 58

Step-by-step explanation:

You look at the first triangle that gives you the two angles, and with the rule that every triangle's angles inside it need to add up to 180 degrees, you can determine that the missing angle is 46 degrees, which translates over to the other triangle, meaning that a would be 44 degrees.

The other triangle has two identical angles, being 61 degrees, which helps translate to the smaller triangle, again allowing you to infer that b is 58 degrees

Answer:

Arc KL [tex]=23[/tex]

Arc OM [tex]=113[/tex]

Step-by-step explanation:

We know that Angle NPM is equal to 90 degrees.

Therefore, Angle KPM is also equal to 90 degrees.

We are told that Arc LM is equal to 67.

Thus, the measure for Arc KL is equal to [tex]90-67=23[/tex]

We also know that Angle OPN is equal to Angle KPL.

Therefore, the measure of Arc ON[tex]=23[/tex]

Using that information, we know that Arc OM is equal to [tex]90+23=113[/tex]

Hope I helped!

Answer:

 n = 6

Step-by-step explanation:

Perhaps you want n for ...

  [tex]4\times10^n=4\,000\,000\\\\10^n=1\,000\,000 \qquad\text{divide by 4}\\\\n=6\qquad\text{count the zeros}[/tex]

__

You know that multiplying by 10 appends a 0 to the right end of an integer number. So, a 1 with 6 zeros has been multiplied by 10 six times. The exponent signifies the number of times the factor is repeated. The exponent, n, is 6.

x^2-1^2= (x+1) (x-1)

Answer:

12

Step-by-step explanation:

Since f(x) = 3, you would multiply 3 by 4. This is because you are basically saying that you have 4 x's and each x is equal to 3. 3+3+3+3=12 or 4(3)=12

Answer:

3x + 2

Step-by-step explanation:

The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?

The shape of a poster = Rectangular shape

Hence:

The Perimeter of a Rectangle (Poster) = 2L + 2W

Where:

Length = Height = 7x + 10

Perimeter = 20x + 24

Therefore:

20x + 24 = 2(7x + 10) + 2W

20x + 24 = 14x + 20 + 2W

2W = 20x + 24 - (14x + 20)

2W = 20x + 24 -14x - 20

2W = 6x + 4

W = (6x + 4)/2

W = 3x + 2

Therefore, the width of the poster

= 3x + 2
