El caudal del río Chillón en agosto de 2.020 fue de 1,649 metros cúbicos por segundo.
Una lectura atenta al enunciado de la pregunta indica que el caudal <em>promedio</em> es 5,5 % mayor que el caudal del mes de agosto de 2.020. Por la definición de porcentaje tenemos la siguiente relación entre las dos cantidades:
En consecuencia, el caudal del río Chillón es igual a:
El caudal del río Chillón en agosto de 2.020 fue de 1,649 metros cúbicos por segundo.

Answer:
88 degree
Step-by-step explanation:
We assume the measure of MN is x degree.
As the measure of LP is 30 degree more than that of MN, so that the measure of LP is: x + 30 degree
In the circle, as 4 points M,N,P,L are on the circle, we have:
+) ∡MPN = 1/2 * (measure of ∡MPQMN) = x/2 = ∡MPQ
+) ∡LMP =1/2 * (measure of LP) = (x+30)/2 = ∡QMP
We have ∡NQM and ∡MQP are complementary angles, so that:
∡MQP + ∡NQM = 180
=> ∡MQP = 180 - ∡NQM = 180 -103 = 77
In the triangle QMP, total measure of 3 internal angles are 180 degree, so that:
∡MQP + ∡QMP + ∡MPQ = 180
=> 77 + (x + 30)/2 + x/2 = 180
=> 77 + x/2 + 15 + x/2 = 180
=> x = 180 -77-15= 88
So that the measure of MN is 88 degree
Answer:
4y(5) is basically 4y multiplied by 5. 4 x 5 = 20 then add the coefficient "y".
4y(5)= 20y
$5.25/5=$1.05
So each notebook costs $1.05
Therefore 3 would cost $3.15
