5) Dos ciudades \( A \) y \( B \) están separadas por una distancia de 600 Km , de \( A \) parte hacia \( B \) un móvil con una velocidad constante de \( 150 \mathrm{Km} / \mathrm{h} \), de \( B \) una hora después parte otro móvil en la misma dirección y sentido de \( A \) con velocidad constante de \( 100 \mathrm{Km} / \mathrm{h} \) calcular: a) a que distancia de la ciudad \( B \) el móvil \( A \) alcanza al otro, b) distancia total recorrida por el móvil \( A, C) \) tiempo del movimiento de cada móvil. Nota: podemos decir \( T_{B}=T_{A}-1 \)

Em uma fazenda, foi colhida certa quantidade de espigas de milho pela manhã, \( \circ \) dobro dessa quantidade à tarde e o triplo à noite, totalizando 60 espigas colhidas durante todo o dia. A equação que representa a situação descrita é \( x+2 x+3 x=60 \), em que x indica a quantidade de espigas colhidas pela manhã. Qual é o valor de \( x \) nessa equação? A. 5 B. 6 C. 10 D. 12

Write a new equation that has the same solution as \( 4 t=20 \). Show your work to prove it has the same solution.

Write down the exact value of each of the six trigonometric functions of \( 30^{\circ} \). sin \( 30^{\circ}=\square \) (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) \( \cos 30^{\circ}=\square \) (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) tan \( 30^{\circ}=\square \) (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) \( \csc 30^{\circ}=\square \) (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) sec \( 30^{\circ}=\square \) (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) \( \cot 30^{\circ}=\square \) (Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.)
