En un estacionamiento cobran $12.00 la hora y $3.00 por 1/4 de hora ¿Cuánto debo pagar si estacione mi coche a las 11.15am y los saque a las 3.00pm
Ayuda plis doy coronita.
Answers
Answer:
$45
Step-by-step explanation:
De 11.00am a 3.00pm hay 4 horas de diferencia.
Eso seria 12x4=$48
Pero necesitamos restarle 1/4 de hora, por lo que se estaciono a las 11.15am y no a las 11.00am
1/4 de hora o 15min= $3.00
48-3=45

Answer:
E = J, and X = 11
Step-by-step explanation:
Okay. So we know that the total degree in a triangle is 180 degrees. We see that the two triangle are similar (E = J) so J = 80, S = 36, and P = 4x +20
We can make this into the equation 80 + 36 +4x +20 = 180
We then simplify 136 + 4x = 180
Isolate 4x 4x = 180 - 136
4x = 44

Answers
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
