How is the sign for PI ???

Considerando la estatura de Fernando, la longitud de su sombra y la distancia con respecto a la lámpara, la altura de la lámpara encendida es de 7.20 metros. (Opción correcta: A)

En la geometría Euclídea el concepto de proporcionalidad está asociado con el concepto de semejanza entre triángulos. Esta relación subyace en el hecho que si tenemos garantizado que existen un número suficiente y conocido de valores y características comunes entre los dos triángulos, entonces podemos determinar los valores faltantes.

En esta pregunta tenemos dos triángulos rectángulos que son semejantes, por ende, proporcionales. Por la definición de proporcionalidad derivamos la siguiente expresión para la altura de la lámpara:

h/H = x/X     (1)

Donde:

A continuación, reemplazamos las variables conocidas y determinamos la altura de la lámpara:

1.80/H = 2/8

H = 4 · (1.80 m)

H = 7.20 m

Considerando la estatura de Fernando, la longitud de su sombra y la distancia con respecto a la lámpara, la altura de la lámpara encendida es de 7.20 metros. (Opción correcta: A)

Answer:

im not writing all that lol

Step-by-step explanation:

So 1 would be 100%, 10/10 and 0 would be, 0/10 and 0% so for 50% for example would be 5/10, 0.5 and so on..

then just think of things that have a 100% chance and all the other percentages... example The sun rising tomorrow. and no chance 0% example the school flying away

Answer:

y = -3, x = 5

Step-by-step explanation:

In the first equation, x = 2 - y, x is on one side. So we can try to isolate the variable x in the second equation by adding 2y + 11 on both sides to get:

x = 2y + 11

So now we have equations x = 2 - y and x = 2y + 11. Therefore 2 - y = 2y + 11.  Now we isolate variable y by adding y on both sides and subtracting 11 on both sides to get -9 = 3y. Divide by 3 on both sides to get y = -3.

Let's substitute that into x = 2 - y. Since y = -3, we now have x = 2 - (-3) = 5.

Answer:

4 units

Step-by-step explanation:

(0, 0 ) and (4, 0 )

since the y- coordinates are equal  then the distance between the points is the difference of the x- coordinates, that is

| 4 - 0 | = | 4 | = 4 or

| 0 - 4 | = | - 4 | = | 4 | = 4

Step-by-step explanation:

There are 3 cubes in the solid's length, 2 in its width, and 3 in its height. Therefore, the number of cubes = length * width * height = 3*2*3 = 18

The volume of a small cube , for a length l, is l³. The length is (1/3)m, so the volume is (1/3)³ = 1/27 m³

volume of solid = number of cubes * area of each cube = 1/27 * 18 = 18/27 m³. This is because we have to figure out the volume of 18 cubes together, and we can just add each cube to the volume 18 times for our answer

The mode of the data set is 4

The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all. Other popular measures of central tendency include the mean, or the average of a set, and the median, the middle value in a set.

Therefore, the mode of the data set is 4

Answer:

  69.6 ft

Step-by-step explanation:

The arc length can be found as a fraction of the circumference. That fraction is the ratio of the central angle measure to the measure for the whole circle.

__

Central angle of remaining arc:

  360° -150° = 210°

Fraction of full circumference:

  210°/360° = 7/12

The circumference of the circle is ...

  C = 2πr = 2π(19 ft) = 38π ft.

Then the length of the remaining arc is ...

  (7/12)(38π) ft ≈ 69.6 ft

Answer:

Step-by-step explanation:

We can prove ∠Q ≅ ∠U, by showing the triangles congruent.

Given that a pair of triangles, ΔSQR and ΔTUR, connected at the point R, in which QR ≅ RU, SR ≅ RT.

We need to prove that ∠Q ≅ ∠U,

So, to prove the same we will use the concept of congruent triangles, the type of triangles in their corresponding parts are congruent, by showing the triangles congruent we can prove ∠Q ≅ ∠U.

1) QR ≅ RU, SR ≅ RT (given)

2) ∠QRS ≅ ∠TRQ (vertical angles are congruent)

3) ΔSQR and ΔTUR (by SAS congruency rule)

4) ∠Q ≅ ∠U (CPCTC)

Hence proved.

Answer: 4.8 miles a day

Step-by-step explanation:

Goal distance 23.2Miles

He rides 4miles, he is left with 23.2- 4= 19.2

Divide 19.2 into 4 days

Nathaniel needs to ride an average of 4.8 miles per day for the next 4 days to meet his goal of riding 23.2 miles this week.

Here, we have to find the average number of miles Nathaniel needs to ride each day to meet his goal, we can use the formula:

Average miles per day = (Total miles goal - Miles already ridden) / Number of days left

Let's plug in the values:

Total miles goal = 23.2 miles

Miles already ridden = 4 miles

Number of days left = 4 days

Now, we get,

Average miles per day = (23.2 - 4) / 4

Average miles per day = 19.2 / 4

Average miles per day = 4.8

So, Nathaniel needs to ride an average of 4.8 miles per day for the next 4 days to meet his goal of riding 23.2 miles this week.

Answer:

0.267 square units (or 8/30 square units)

Step-by-step explanation:

width = 3 rectangles

length = 10 rectangles (left to right)

area = width * length = 30 rectangles

the striped rectangle is made up of 8 regular rectangles

thus, (area we want) / (total area) = 8/30 of the whole ≈ 0.267 of the whole

the whole is 1 square unit, so 0.267 of 1 square unit =  0.267 * 1 square unit = 0.267 square units

Answer:

d ≤ -3

Step-by-step explanation:

Given that:

−13d + 6 ≤ 45

Solve:

Subtracting 6 from both sides

−13d + 6 ≤ 45

       -6    -6

-----------------------

−13d ≤  39

Multiply both sides by -1 which reverse the inequality

13d ≤ -39

Now divide both sides by 13

13d/13 ≤ -39/13

d ≤ -3

Thus the Answer is:

d ≤ -3
