Answer:

The distance from point A to given line is: 2√5 or 4.472 units

Step-by-step explanation:

Given equation of line is:

[tex]-x+2y= 14[/tex]

And the point is:

[tex]A = (x_1,y_1) = (-14,5)[/tex]

The standard form of equation of line is:

[tex]Ax+By+C = 0[/tex]

Converting the given equation into standard form

[tex]-x+2y-14=0[/tex]

The distance of a point (x1,y1) from a line is given by the formula:

[tex]d = \frac{|Ax_1+By_1+C}{\sqrt{A^2+B^2}}[/tex]

In the given details,

A = -1, B = 2, C = -14

x1 = -14, y1 = 5

Putting the values in the formula

[tex]d = \frac{|(-1)(-14)+(2)(5)-14|}{\sqrt{(-1)^2+(2)^2}}\\d = \frac{14+10-14}{\sqrt{1+4}}\\d = \frac{10}{\sqrt{5}}\\d = \frac{5*2}{\sqrt{5}}\\d = \frac{\sqrt{5}*\sqrt{5}*2}{\sqrt{5}}\\d = 2\sqrt{5}\\d = 4.472\ units[/tex]

Hence,

The distance from point A to given line is: 2√5 or 4.472 units

Answer:

180πcm²

Step-by-step explanation:

The formula for calculating curved surface area of a cylinder is

CSA=2πrh

r I the radius= 18cm/2 = 9cm

Let the height be 19cm

CSA = 2π(9)(10)

CSA = 180πcm²

Hence the length of the curved surface area is 180πcm²

Note that the height of the cylinder was assumed

4 to 3

Step-by-step explanation:

Colton wrote a ratio comparing the number of sports video games that he owns to the number of driving video games that he owns as 4:3. Which ratio is equivalent to Colton’s ratio?

Three-sevenths

Four-sevenths

3 to 4

4 to 3

Ratio of the number of sports video games that he owns to the number of driving video games that he owns = 4 : 3

number of sports video games that he owns : number of driving video games that he owns = 4 : 3

4 : 3 = 4 / 3

Three-sevenths = 3 / 7

Four-sevenths = 4 / 7

3 to 4 = 3 / 4

4 to 3 = 4 / 3

The equivalent ratio to Colton’s ratio is 4 to 3

Answer:

[tex]d = \frac{4 - 3c}{c + 1} [/tex]

Step-by-step explanation:

To make d the subject of formula, we need to rearrange the equation such that we arrive at d= _____.

[tex]c = \frac{4 - d}{d + 3} [/tex]

Remove the fraction by multiplying (d +3) on both sides:

[tex]c(d + 3) = 4 - d[/tex]

Expand:

[tex]cd + 3c = 4 - d[/tex]

Bring all the d terms to one side and move the others to the other side of the equation:

[tex]cd + d = 4 - 3c[/tex]

Factorise d out:

[tex]d(c + 1) = 4 - 3c[/tex]

Divide by (c +1) on both sides:

[tex]d = \frac{4 - 3c}{c + 1} [/tex]

Answer:

9 pieces

Step-by-step explanation:

first convert 40cm to m by dividing by 100cm

then divide 3.6m by 0.4 then the ans will come.

A) There are 9 strings each of length of 40 cm.
B) 0.20, 5/12, 75% is already in the ascending order.
C) The bearing of Klayton from Lakeshore is also 196°.

In mathematics, it deals with numbers of operations according to the statements.

A) A 3.6 m long string is to be cut into pieces, each of length 40 cm.
3.6 m = 3.6 * 100cm
3.6 m = 360 cm
Let the number of stings be x
x * 40 = 360
x = 360 / 40
x = 9
there are 9 strings each of length of 40 cm.

Arranging the following in ascending order of magnitude: 0.20, 5/12, 75%
0.20, 5/12, 75% is already in the ascending order.

The bearing of Lakeshore from Klayton is 196°. The bearing of Klayton from Lakeshore is also 196°.

Answer: To do that you divide the top to the bottom so 4,102 divided by 7 which is 586

Answer: 586

Step-by-step explanation:

The decimal notation is 586.0

A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.

Given:  4,102/7

Now to write the above fraction into decimal we have to divide the fraction

as

4102/7= 586

Answer:

Side lengths of the square are 10 units. The area of the square is 100 units squared

Step-by-step explanation:

Use the Pythagorean theorem to find the hypotenuse of the right triangles. The lengths of the hypotenuses is the same as the side lengths of the square. Since it's a square all the sides are congruent(same length) To find the area of the square multiply the base times the height(10x10) because it's a square the area is squared.

Answer:

Step-by-step explanation:

hey there,

< Here's how you do subtraction in fractions!

Make sure you find a least common denominator. Here, it's given to you to be 15. Usually, you can just multiply the two denominators but then it would be quite large at times, so you kind of just have to guess.

How did they go from  [tex]\frac{4}{5} x-\frac{1}{3} x[/tex]  to [tex]\frac{?}{15} x[/tex]?

Well, they used a least common denominator. 5 was multiplied by 3 to create 15, and 3 was multiplied by 5. But when you multiply the bottoms, you have to multiply the tops of the fraction too (the numerators).

So 4/5x was multiplied by 3. Denominator turned out to be 15, and now the top is 4x3 = 12. So the fraction is 12/15.

1/3x, on the other hand, was multiplied by 5. Denominator was also 15 so they're the same, and top is 1x5 = 5. So the fraction is 5/15.

Now, let's put them together.

[tex]\frac{12}{15}x-\frac{5}{15} x[/tex]

When subtracting x, the x just stays there, so if it was 10x-4x, the answer would've been 6x. So now let's subtract!

12-5 = 7, and the denominator stays the same.

The answer is [tex]\frac{7}{15} x[/tex]. So the numerator, or answer to your question, would be 7.
