Answer:

The answer is 110 degrees C.

Step-by-step explanation:

The melting point of substance X is -20 degrees Celsius and the boiling point is 90 degrees Celsius.

To find the difference between the degrees, we will subtract the values.

So, the difference between these points will be =

90-(-20)

= 90+20=110

The answer is 110 degrees C

Se desea pintar un cuadrado inscrito en una circunferencia de radio R=3cm como se muestra en la figura. Calcular el área del cua
Leno4ka [110]

Answer:

El área del cuadrado es de 3 centímetros cuadrados.

Step-by-step explanation:

Dado que se desea pintar un cuadrado inscrito en una circunferencia de radio R=3cm como se muestra en la figura, para calcular el área del cuadrado se debe realizar el siguiente cálculo:

Radio = diámetro / 2

3 = X/2

X = 6

Hipotenusa del triángulo interno: 6 cm

Aplicando teorema pitagórico: lado al cuadrado mas lado al cuadrado es igual a hipotenusa al cuadrado.

L^2 + L^2 = 6

2L^2 = 6

L^2 = 6/2

L = √ 3

L = 1.732

Área de un cuadrado = L x L = L^2 = 3

Por lo tanto, el área del cuadrado es de 3 centímetros cuadrados.

The measure of an angle is twenty-four times the measure of its complementary angle. What is the measure of each angle?
Bogdan [553]

Answer:

<h2>         3.6° and 86.4°</h2>

Step-by-step explanation:

24x   - measure of an angle

x      - the measure of a complementary angle

Complementary angles adds to 90°

x + 24x = 90°

25x = 90°

x = 90°÷25

x = 3.6°

24x = 24·3.6° = 86.4°

The sets of numbers 3, 4, 5 and 5, 12, 13 are examples
Wewaii [24]

Answer:

  • 8, 15, 17 — yes
  • 15, 20, 25 — yes
  • 20, 48, 52 — yes
  • 2, 9, 11 — no
  • 39, 80, 89​ — yes

Step-by-step explanation:

The squares of the three numbers in each of the given triples are listed. When the sum of the first two numbers is equal to the third, the set of numbers in the triple is a Pythagorean triple.

  {64, 225, 289}, yes

  {225, 400, 625}, yes — a 3,4,5 triple multiplied by 5

  {400, 2304, 2704}, yes — a 5,12,13 triple multiplied by 4

  {4, 81, 121}, no*

  {1521, 6400, 7921}, yes.

___

* the smallest set of integers that is a Pythagorean triple is {3, 4, 5}. The number 2 in this group tells you this cannot be a PT.
