Answer:
An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 14 more than two times the length of the bottom of the triangle. The last side is 10 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

Answer:
ΔT = ΔT0 e^-K T
As I understand Newton's Law of Cooling
ΔT at any time is the difference between the temperature and the surroundings
Originally ΔT0 = 95 - 22 difference between 95 and room temperature
65 - 22 = 33 = 73 e^-KT where t is time to cool to 65 deg
ln (33/73) = -KT K = .794 / 5 = .159 where 5 is time to cool to 65 deg
40 - 22 = 73 e^-.159 T where t is time to cool to 40 deg
18 = 73 e^-.159 T
ln (18 / 73) = -.159 T
T = 8.8 min
It would take 8.8 min for the object to cool to 40 deg C
Suppose the object cooled from 95 to 90 deg, then
ln 68 / 73 = -.159 T and T = .45 min
La pregunta está incompleta ya que no se da el costo de la colocación de baldosas por m².
Suponga que el costo de los mosaicos por m² = c
Respuesta:
39.06c
Explicación paso a paso:
El costo del embaldosado será:
El costo por m² * área total a embaldosar
Dado que :
La dimensión de la habitación a embaldosar es:
Longitud = 9,30 metros
Ancho = 4.20 metros
El área total de la habitación a embaldosar es = Largo * ancho
Área total de la habitación a embaldosar = 9,30 m * 4,20 m
Superficie total de la habitación a embaldosar = 39,06 m²
Si el costo del mosaico por m² = c
El costo de embaldosar la habitación será:
39,06 * c = 39,06c
Answer:
X=37.6 because the 90 degree angle plus the 52.4 equals 142.4 the subtract that from 180 then ta da.
