length of 14 cm.
A. 196 cm²
12
SL
B. 196 cm³
cm
C. 14 cm²
D. 2744 cm³
3
Answer:
D
Step-by-step explanation:
the volume (V) of a cube is calculated as
V = s³ ( s is the side length ) , then
V = 14³ = 2744 cm³
Answer:
D. 2744 cm³
Step-by-step explanation:
volume can be found by multiplying length × width × height
because we know that this is a cube, all side lengths are the same (meaning length, width, and height will all be the same)
so, we know our side length is 14cm, meaning that all of our measurements {length/width/height} are 14cm
length × width × height = volume
14 × 14 × 14 = 2744
when we write volume, we write it as cubed (x³)
{similarly, when we write area, we write it as squared (x²)}
so, we would write the volume of this cube to be 2744 cm³
(option D)

Answer:
-3 < x < 7
Step-by-step explanation:
The domain of a graph is all of the x-values that are included in the function. Since the graph is continuous (one connected line), you can determine the domain by identifying the x-values associated with the line's endpoints. These values are x = -3 and x = 7. Remember, the x-value located on a closed dot is not included in the domain. Therefore, the domain of the graph is -3 < x < 7.
The magnitude of the electrical force acting between a 2.4 × 10–8 c charge and a 1.8 × 10–6 c charge that are separated by 0.008 m is n, rounded to the tenths place.
The magnitude of the electrical force acting between both the given charges which are separated by 0.008 m is 6.07 N.
Given Charges 2.4*[tex]10^{-8} C[/tex] and 1.8 *[tex]10^{-6} C[/tex] that are separated by 0.008 m.
We have to find the magnitude of the electrical force acting between the charges. Magnitude is the property which determines the size of an object or process. Force is an influence that can change the direction of an object.
To find the magnitude we have to use Coulomb's law which says that
[tex]F_{E}=K*(q_{1}*q_{2}/d^{2}[/tex]
where K is Coulomb's constant whose value is [tex]8.9910^{9}Nm^{2} C^{2}[/tex].
[tex]q_{1}[/tex]=[tex]2.6*10^{-8} C[/tex] and
[tex]q_{2}=1.8*10^{-6} C[/tex] are the electric charges.
d=0.008m is the separation distance between the charges.
Putting the values in the given formula we get:
[tex]F_{E} =8.99(10)^{9}Nm^{2}/C^{2} *(2.4(10)^{-8}C(1.8(10)^{-6}C)/(0.008m)^{2}[/tex]
=6.07 N
Hence the magnitude of force acting between [tex]2.4*10^{-8} C[/tex] and [tex]1.8*10^{-6}C[/tex] is 6.07 N.

Answer and Explanation:
Area is the measure of how large a 2-dimensional space is.
For example, a 6 × 2 grid of eggs contains 12 egg spaces.
In math, the unit for area is always a linear measurement squared (for example [tex]m^2[/tex], [tex]cm^2[/tex], and [tex]ft^2[/tex]).
Perimeter is the measurement of the border of a space.
For example, the fence around a 5 × 10 ft garden can be solved for by adding up each individual side of fencing (see the attached image).
The unit for perimeter is always a linear measurement, like m, cm, or ft.
Using this knowledge, for question a, simply multiply the side lengths to get the area. Remember to use [tex]ft^2[/tex] as the unit.
For question b, the answer is perimeter, since it is measuring the border length of the model court.
For question c, the answer is area, since it is measuring the size of the model court's wooden floor.

How do I solve y=x-2 and y=3x+5?
Answer:
x = -7/2 and y = -11/2
Step-by-step explanation:
These equations are known as slope-intercept equations.
Slope-intercept equation are a type of linear equation.
The slope-intercept format is: y = mx + b
m = the slopeb = the y-interceptBecause there are two equations, this would be a system of equations.
So, to figure this out, we need to use the substitution method.
_____________________________________________
Problem:
Solve y=x−2;y=3x+5
Solution:
Step: Solve y=x−2 for y:
Step: Substitute x-2 for y in y = 3x + 5:
y = 3x + 5
x - 2 = 3x + 5
x−2+−3x=3x+5+−3x(Add -3x to both sides)
−2x−2=5
−2x−2+2=5+2(Add 2 to both sides)
−2x=7
-2x/-2 = 7/-2 (Divide both sides by -2)
x = -7/2
Step: Substitute -7/2 for x in y = x - 2:
y = x - 2
y = -7/2 - 2
y = -11/2(Simplify both sides of the equation)
Answer:
x = -7/2 and y = -11/2

Step-by-step explanation:
SInce you notice there is movies with an 8 difference....
Answer:

Step-by-step explanation:
This seems to be a problem related to ratios. We are given that, for every 24 kids' movies, there are 32 horror movies. We need to figure out how many horror movies there would be if there were just 3 kids' movies. We can set up an equation using proportions:
[tex]\frac{24}{32}=\frac{3}{x}[/tex]
We don't know how many horror movies there would be so we can let this quantity equal x. Now, we can cross multiply and solve for our unknown:
[tex]24x = 3*32\\24x = 96\\x = 4[/tex]
This means that there are 4 horror movies

The total volume of air that coach Tim will need to fill is [tex]1,340^{3} inches[/tex].
To find the total volume of air that coach Tim will need:
The formula of volume = [tex]\frac{4}{3}[/tex] × [tex]\pi[/tex] × [tex]r^{3}[/tex]

[tex]\frac{4}{3} * 3.14 * 64\\\frac{4}{3} * 201.06\\4 * 67.02\\268.08[/tex]

Answer:
x = 192
Step-by-step explanation:
The three right triangles in the figure are all similar, so their sides are proportional.
ProportionThe length marked x is the long side of the smallest triangle, and the short side of the middle-size triangle. The long side of the middle-size triangle is ...
400 -144 = 256
We now have enough information to write the proportion ...
long side/short side = x/144 = 256/x
Multiplying by 144x gives ...
x² = (144)(256)
x = √(144×256) = 12×16 = 192
The length x is 192 units.
Grogg has two bags of marbles, each of which contains some red marbles and some blue marbles (and no marbles of any other color). The ratio of red marbles to blue marbles in the first bag is 3:5. The ratio of red marbles to blue marbles in the second bag is 3:2. When the two bags of marbles are mixed together, the ratio of red marbles to blue marbles is 11:9. What is the ratio of the number of marbles in the first bag to the number of marbles in the second bag?
The ratio of the number of marbles in the first bag to the number of marbles in the second bag is 2:7.
How to determine the required ratio?First of all, we would assign the variables x and y to the marbles in the first and second bag respectively. Also, let F and S represents the first and second bag respectively.
For the first bag, we have:
Ratio = 3:5 = 3x:5x = 3x + 5x = 8x
For the first bag, we have:
Ratio = 3:2 = 3y:2y = 3y + 2y = 5y
Tabulating these values, we have:
Red Blue
First bag 3x 5x
Second bag 3y 2y
The two red marbles = 3x + 3y.
The two blue marbles = 5x + 2y.
Next, we would write the ratio of the total red marbles to the total blue marbles:
Total red/Total blue = 11/9
(3x + 3y)/(5x + 2y) = 11/9
Cross-multiplying, we have:
27x + 27y = 55x + 22y
27y - 22y = 55x - 27x
5y = 28x
y = 28x/5
y = (28/5)x
y = 5.6x
Remember from the second bag, S = 5y:
S = 5(5.6x)
S = 28x.
Thus, the ratio of the number of marbles in the first bag to the number of marbles in the second bag is given by:
F/S = 8x/28x
F/S = 8/28
F/S = 2/7
F:S = 2:7.

The Dysons love to give parties. Last Friday, they gave a party and the doorbell rang 15 times. At the first ring, one guest arrived. Each time the doorbell rang after that, two more guests arrived than the time before. On Saturday they had another party. At the first ring of the doorbell a single guest arrived, at the second ring two guests appeared, at the third ring three guests and so on. If the doorbell rang 20 times Saturday night, how many guests attended? Was this party bigger than Friday's party? How do you know? 2. Draw a picture to show one way to solve this problem.
The number of guests on Saturday is 210 and it is greater than the party of Friday (15 guests)
Calculations and ParametersLast Friday had 15 guests
The sum total of guests on Saturday= 210 guests (using Arithmetic progression)
Using the arithmetic progression sum formula:
1 * 20 + (20 * 19/2) * 1= 210
Therefore, 210 > 15, so we can conclude that the Saturday night party was bigger than Friday's own.
