How many moles are in the 500.0g lump of coal (which is made of carbon) that you received in your Christmas stocking last year?
How many carbon atoms are in this 500.0g lump of coal?
Answer:
Number of moles = 41.67 (Approx)
Number of carbon atom = 250.97 x 10²³ (Approx)
Step-by-step explanation:
Given:
Amount of carbon = 500 g
Find:
Number of moles
Number of carbon atom
Computation:
Number of moles = 500 / Atomic number of weight
Number of moles = 500 / 12
Number of moles = 41.67 (Approx)
Number of carbon atom = Number of moles x Avogadro number
Number of carbon atom = 41.67 x 6.023 x 10²³
Number of carbon atom = 250.97 x 10²³ (Approx)
Is 11 a solution to 3(x+6)=4x ?
Answer:
The number 11 is not a solution for the given equation.
Step-by-step explanation:
We are given an equation with one variable. We can use simplifying processes to solve the equation.
[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]
We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.
[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]
Therefore, 11 is not a solution for the given equation.
Answer:
First of all,We need to find the value of x to find that 11 is the solution to 3(x+6)=4x or not.[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]
[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]
[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]
Let's put x as 11:[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]
[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]
[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]
51 doesn't equal to 44.So,11 is not the correct solution to 3(x+6)=4x.A scale factor of 4 applied to the dimensions of the prism. What effect will this have on the volume?
Answer:
its not A just took the test
Step-by-step explanation:
The effect this scale factor has on the volume is that the volume will be 64 times larger. The correct option is B.
What is a Scale factor?Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. They have scaled versions of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called a scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple linear things twice grow by the square of the scale factor. Thus, we need to multiply or divide by k².
to get each other corresponding quantities from their similar figures' quantities.
So the area of the first figure = k² × area of the second figure
Similarly, increasing product-derived quantities will need increased power of 'k' to get the corresponding quantity. Thus, for volume, it is k cubed. or
The volume of the first figure = k³ × volume of the second figure.
It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
Since the volume is the product of three linear quantities.
Therefore, if the scale factor of 4 is applied to the given prism then the volume of the prism will grow by 4³. Thus, we can write,
The volume of the scaled prism = 4³ ×Volume of the original volume
The volume of the scaled prism = 64 ×Volume of the original volume
Hence, the effect this scale factor has on the volume is that the volume will be 64 times larger.

Is this correct, i did 21.5 times 33.6 and converted it to yards to the nearest tenth and i got 80.3
Answer:
Thats what i got too :)
Step-by-step explanation:
You have the correct answer. It is 80.3 square yards.
Work Shown:
Area of parallelogram = length*width = 21.5*33.6 = 722.4 sq ft
1 yard = 3 ft
1 sq yd = 9 sq ft ... square both sides
To convert from square feet to square yards, we'll divide by 9
This is the same as multiplying by 1/9
722.4 sq ft = (722.4 sq ft)*(1 sq yd/9 sq ft)
722.4 sq ft = (722.4)*(1/9) sq yards
722.4 sq ft = 80.2667 sq yards
722.4 sq ft = 80.3 sq yards

Answer:
∠ B ≈ 62.73°
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{8}{9}[/tex] , thus

Identify the matrix transformation of ΔMNO, which has coordinates M(1, 3),N(5, 2), and O(3, −3), for a translation 2 units left and 4 units up. Then identify the correct vertices of the image
Answer:
M(-1,7), N(3,6), O(1,1)
Step-by-step explanation:
The coordinates of ΔMNO are M(1, 3),N(5, 2), and O(3, −3).For a translation, 2 units left and 4 units up the correct vertices of the image will be M'(-1,7), N'(3,6), and O'(1,1).
It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that the coordinates are M(1, 3),N(5, 2), and O(3, −3).
We have to translate 2 units left and 4 units up.
The coordinates obtained after applying the given geometric transformation are M'(-1,7), N'(3,6), O'(1,1)
Thus, the coordinates of ΔMNO are M(1, 3),N(5, 2), and O(3, −3).For a translation, 2 units left and 4 units up the correct vertices of the image will be M'(-1,7), N'(3,6), and O'(1,1).

14 girls in the class
Step-by-step explanation:
use percentage equation, p = nw or part of the question = the percentage times the total amount.
So in this case our p, or girls in the class (which is part of the total), is unknown. We have the percentage and we have the total. So all we need to do is multipy them. However how do you multiply percentage . . . well 40 percent also equalts to 0.40. So all you have to do is multiply .40 by 35 and you have your answer.
Find the value of x
Answer:
50?
Step-by-step explanation:
Answer:
x= 106
Step-by-step explanation:
The angle opposite 32 is also 32. Considering 44, the missing angle in that triangle would be 104. The angle to the left of 104 would be 76, and if you consider that angle 30 you are left with the measure of 74. X is the angle next to 74, so it makes sense for it to measure 106 because the values must add to 180, and even if it's not drawn to scale 106 looks accurate

Answer:
a, b ,e
Step-by-step explanation:
The solutions to the equation f(x) = g(x) are x = -3.3 and x = 5.2
The correct answers are option (A) and option (E)
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
What is solution to equations?"It is a value or a set of values, when substituted for the unknowns, the equation becomes true."
For given question,
We have been given the graph of a quadratic function f(x) and an absolute value function g(x).
We need to find the x-values that are approximate solutions to the equation f(x) = g(x).
To solve the equation f(x) = g(x), we look for the points where the graphs of f(x) and g(x) intersect.
The intersection point of f(x) = g(x) appears to be at point which lie in the second quadrant and the x-value lie between -2 and -4.
Also, the second intersection point lie in the fourth quadrant where x value is in between 4 and 6.
So, the solutions to the equation f(x) = g(x) are x = -3.3 and x = 5.2
The correct answers are option (A) and option (E)
