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.

We have [tex]x^{-n} = \frac1{x^n}[/tex] if [tex]n[/tex] is a positive integer and [tex]x\neq0[/tex], as well as [tex]x^0 = 1[/tex] if [tex]x\neq0[/tex]. So right away we can simplify to

[tex]\left(x^{-1} y^2\right) \left(-3 x^2 y^0\right) = \left(\dfrac{y^2}x\right) \left(-3x^2\right) = -\dfrac{3x^2y^2}x[/tex]

If [tex]x=0[/tex], then the starting expression is undefined. So we accept that [tex]x=0[/tex], in which case [tex]\frac xx = 1[/tex], and the overall expression simplifies to

[tex]\left(x^{-1} y^2\right) \left(-3 x^2 y^0\right) = \boxed{-3xy^2}[/tex]

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

The ratio of the number of marbles in the first bag to the number of marbles in the second bag is 2:7.

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 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.

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

Answer:

  x = 192

Step-by-step explanation:

The three right triangles in the figure are all similar, so their sides are proportional.

The 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.
