Which of the following representative fractions would indicate the largest scale map? Options: • 1:1 • 1:0 • 1:1,000,000 • 1:24,000

Answers

Final Answer:

The largest scale map is indicated by the representative fraction 1:1. Option A is correct.

Explanation:

In cartography, the representative fraction (RF) of a map indicates the scale of the map, specifically the ratio between a distance on the map and the corresponding distance on the Earth's surface. A larger RF value means a larger scale map, which represents smaller areas with more detail.

Now, let's compare the given options:

1. 1:1 - This RF means that one unit on the map represents one unit on the ground, essentially a one-to-one scale. It doesn't get any larger than this, so this is the largest scale possible.

2. 1:0 - This doesn't make sense in cartography because you cannot represent the Earth's surface with zero on one side of the ratio. It's an invalid option.

3. 1:1,000,000 - This RF indicates that one unit on the map represents one million units on the ground. This is a much smaller scale compared to 1:1, so it represents a much larger area with less detail.

4. 1:24,000 - This RF means that one unit on the map represents 24,000 units on the ground. While this is a larger scale than 1:1,000,000, it is still smaller than 1:1, which is the largest scale.

In summary, the largest scale map is represented by 1:1. Option A is the answer.

Answer:

The representative fraction (RF) of a map indicates the scale of the map. In a representative fraction, the first number represents a unit of measurement on the map, and the second number represents the corresponding unit of measurement in the real world.

Among the options provided, a larger scale map would have a smaller second number because it means that one unit of measurement on the map represents a smaller unit of measurement in the real world. So, the largest scale map in the given options is:

1:24,000

In this case, 1 unit on the map represents 24,000 units in the real world, indicating a very detailed and large-scale representation of the area.

Step-by-step explanation:

A system of linear equations is shown below. 2x+4y=103x−y=8 Maria is attempting to prove that by replacing 2x+4y=10 with a different equation it will sometimes produce a new system of equations with the same solution. Maria plans on multiplying 2x+4y=10 by 2 and then adding the results to the equation 3x−y=8 in order to create a new equation. Maria claims that the new equation that she will replace 2x+4y=10 with is 7x+7y=12. Is Maria correct? Why or why not?

Answers

Answer:

No she is wrong.

Explanation:

$\sf\n2x+4y=10...........(1)\n3x-y=8...........(2)\n\n\textsf{First Maria multiplies equation(1) by 2:}\n2(2x+4y)=2(10)\n\textsf{or, }4x+8y=20........(3)\n\n\textsf{Then she adds the resulting equation to equation (3):}\n(4x+8y)+(3x-y)=20+8\n\textsf{or, }7x+7y=28$

$\textsf{Maria is wrong because she obtained the wrong equation.}$

Use the Binomial Theorem to expand (x - 2y)^3

Answers

From Binomial Theorem (x-2y)³:
( $((3)/(0)) x^(3)+( (3)/(1) ) x^(2) *(-2y)+( (3)/(2))x*( -2y)^(2) +( (3)/(3)) x^(0) (-2y)^(3) =$ $(3!)/(0!3!) x^(3)- (3!)/(1!2!) x^(2) 2y- (3!)/(2!1!)x4 y^(2)- (3!)/(3!0!)8 y^(3)$ =x³-6x²y-12xy²-8y³

$(x-2y)^3=x^3-6x^2y+12xy^2-8y^3$

Choose the value for which 2/a+8 is undefined

Answers

If the value is:

$\sf{(2)/(a+8)}$

Then it will be undefined when the denominator is equal to 0.

So set the denominator equal to 0

a + 8 = 0
a = -8

So when

$\huge{\boxed{\bf{a=-8}}}$

then the value will be undefined.

Just a note:

$\sf{(x)/(0)=}$ undefined

$\sf{(0)/(x)=0}$
