Jane move from my house with 78 ft.² of closet space to an apartment with 49.14 ft.² of closet space what is the percentage decr
natulia [17]

Answer:

37%

Step-by-step explanation:

First to find the percent of decrease you have subtract the largest number by the smaller number. So 78 ft² - 49.14 ft². This would get you to 28.86 ft². Then you would divide the original number, (in this case 78) by the difference (28.86). Once you divide you get .37, you will have to multiply by 100 to get the percent. So the percent of decrease is 37%.

Which is longer, 4000 ft or 1 kilometers kilometers
TiliK225 [7]
Answer=4000ft

There are 3280.84 feet in 1 kilometer

1km=3280.84ft

4000ft >3280.84 ft

therefore, 4000ft is longer than 1 km

4000ft>1km

Una escalera de 131313 metros está recargada contra una pared cuando su base empieza a resbalar. Cuando la base está a 121212 me
Artyom0805 [142]

Answer:

El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.

Step-by-step explanation:

Sea x la distancia horizontal entre la pared y la base de la escalera y l la longitud de la escalera, medidas en metros. Además, tenemos que \theta es el ángulo entre la escalera y el piso, medido en radianes.

Si la pared y el piso son ortogonales entre sí, entonces podemos utilizar la siguiente relación trigonométrica que relaciona las variables anteriores:

\cos \theta = \frac{x}{l}  (1)

Por diferenciación implícita y la definición de razón de cambio tenemos que:

-\sin \theta \,\dot \theta = \frac{\dot x}{l} (2)

Donde:

\dot x - Razón de cambio de la distancia horizontal entre la pared y la base de la escalera, medida en metros por segundo.

\dot \theta - Razón de cambio del ángulo entre el piso y la escalera, medida en radianes por segundo.

Pero tenemos que el seno del ángulo está definido por:

\sin \theta = \frac{\sqrt{l^{2}-x^{2}}}{l} (3)

Si aplicamos (3) en (2), expandimos la ecuación como sigue:

-\frac{\sqrt{l^{2}-x^{2}}}{l}\,\dot \theta = \frac{\dot x}{l}

\dot \theta = - \frac{\dot x}{\sqrt{l^{2}-x^{2}}} (4)

Si tenemos que \dot x = 5\,\frac{m}{s}, l = 13\,m y x = 12\,m, entonces la razón de cambio del ángulo es:

\dot \theta = -\frac{\left(5\,\frac{m}{s} \right)}{\sqrt{(13\,m)^{2}-(12\,m)^{2}}}

\dot \theta \approx -1\,\frac{rad}{s}

El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.
