The value of the missing part of triangle DFC which is FD would be = 12.

Triangle ACD is congruent to triangle DFC

ED/AD = BC/AC

where;

ED = 9

AD = 15

BC= 12

AC=?

Make AC the subject of formula;

AC= 12×15/9

AC= 180/9

AC = 20

Using the adjacent values of the new and original sides of the triangle to calculate the scale factor.

That is ;

AD is congruent to FC = 15 = 9

But Scale factor = Dimension of the new shape ÷ Dimension of the original shape

Scale factor = 15/9= 1.67

To calculate FD using the scale factor;

1.67= 20/FD

FD= 20/1.67

FD= 12 (approximately)

By proportion formulas and Pythagorean theorem, the length of side FD is approximately equal to 26.571.

Herein we find a geometric system formed by two similar right triangles (ΔABE, ΔACD) and a third distinct right triangle (ΔCDF). Two triangles are similar when both have congruent interior angles and sides that are not congruent though proportional.

Then, the system of similar triangles can be defined by following proportion formula:

AB / AE = AC / AD

x / 6 = (x + 12) / 15

15 · x = 6 · (x + 12)

15 · x = 6 · x + 72

9 · x = 72

x = 8

AB = 8

Now we determine the length of side CD by Pythagorean theorem:

CD = √(AC² - AD²)

CD = √[(x + 12)² + 15²]

CD = √(20² + 15²)

CD = 25

And the side FD is finally found by Pythagorean theorem:

FD = √(CD² + CF²)

FD = √(25² + 9²)

FD = √706

FD ≈ 26.571

There are 1000 cubic centimetres in a litre (cm3). This is so because one cubic centimetre (cc) equals one millilitre (ml), and one litre (l) equals 1000 ml.

1000 ml make up 1 litre (L).

ml (millilitres) = cm3

1000 ml = 1000 cm3

1 L = 1000 cm3

One litre is equal to one thousand cubic centimetres (cm3). This is because one cubic centimetre is equivalent to one millilitre (ml), and one litre is equal to 1000 millilitres (ml). The subsequent actions can be conducted in order to calculate this. Initially, one litre (L) equals one thousand millilitres (ml). Second, one cubic centimetre is equivalent to one millilitre (cm3). Thus, one millilitre is equivalent to one hundred cubic centimetres. Last but not least, one litre equals one thousand cubic centimetres, or 1 L = 1000 cm3. Anybody wishing to translate between the two different volume measures will find this information valuable.

71 degrees Fahrenheit is equal to approximately 21.7 degrees Celsius using the conversion method formula.

To convert Fahrenheit to Celsius, you can use the following formula:

Celsius = (Fahrenheit - 32) x 5/9

Plugging in 71 degrees Fahrenheit, we get:

Celsius = (71 - 32) x 5/9

Celsius = 39 x 5/9

Celsius = 195/9

Celsius ≈ 21.7

Therefore, 71 degrees Fahrenheit is approximately 21.7 degrees Celsius.

The Celsius scale is also known as the centigrade scale, because it is divided into 100 degrees between the freezing and boiling points of water at standard atmospheric pressure.

On the Fahrenheit scale, there are 180 degrees between the freezing and boiling points of water. Therefore, each degree on the Fahrenheit scale is equivalent to 5/9 of a degree on the Celsius scale.

The price of each ticket is given as follows:

The prices for each type of ticket are obtained via a system of equations, for which the variables are given as follows:

On the first day of ticket sales the school sold 12 senior citizen tickets and 6 student tickets for a total of $252, hence:

12x + 6y = 252

2x + y = 42 (simplifying by 6).

y = 42 - 2x.

The school took in $98 on the second day by selling 6 senior citizen tickets and 1 student ticket, hence:

6x + y = 98

y = 98 - 6x.

Equaling the two equations, the value of x is obtained as follows:

42 - 2x = 98 - 6x

4x = 56

x = 56/4

x = 14.

(b)  y = x + 4 ---(1)(using substitution method)

     x = -3y---(2)

     Substitute (2) in (1) we get,

     y = -3y+4

     ⇒4y=4 ⇒y=1

(c)   3x - y = 7 (using graphing method)

      y = 3x - 2

     This system has no intersection point

The centroid of this triangle is located at the point (6, 3).

The centroid of a triangle is the point where the three medians of a triangle intersect. Medians are the line segments that connect each vertex of the triangle to the midpoint of the opposite side.

The centroid is the "center of mass" or the "balance point" of the triangle. In other words, if the triangle were made of a solid material and suspended by a string attached to the centroid, it would balance.

To find the coordinates of the centroid of a triangle, we will use the following formula:

G = (x1 + x2 + x3)/3, (y1 + y2 + y3)/3

Where G is the centroid, and (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the triangle's vertices.

So for the triangle with the vertices s(2, 5), t(6, 5), and r(10, 0), we have:

G = (2 + 6 + 10)/3, (5 + 5 + 0)/3

G = (18/3, 10/3)

G = (6, 3.333...), which we can round to (6, 3)

10 ml is equal to 2 teaspoons. This is because 1 teaspoon is equal to 5 ml. To calculate the number of teaspoons in 10 ml, you must divide 10 ml by 5 ml. 10 ml divided by 5 ml equals 2 teaspoons.

To convert milliliters to teaspoons, you must use the conversion factor of 1 teaspoon = 5 ml. This means that for every 1 teaspoon, there are 5 milliliters. To figure out the number of teaspoons in 10 ml, you must take 10 ml and divide it by 5 ml. This will give you the number of teaspoons in 10 ml.When converting from milliliters to teaspoons, it is important to use the correct conversion factor. If you use the wrong conversion factor, you will end up with incorrect results. For example, if you use 1 teaspoon = 4 ml instead of 1 teaspoon = 5 ml, you will end up with an incorrect result.In addition to using the conversion factor, it is also important to keep in mind that a teaspoon is a measure of volume, not weight. This means that the amount of liquid in a teaspoon may vary depending on the density of the liquid. For example, a teaspoon of water will contain more liquid than a teaspoon of honey.

In conclusion, 10 ml is equal to 2 teaspoons. To convert milliliters to teaspoons, you must use the conversion factor of 1 teaspoon = 5 ml. It is important to remember that a teaspoon is a measure of volume, not weight, and the amount of liquid in a teaspoon may vary depending on the density of the liquid.
