Answer:
x = 29/8c
Step-by-step explanation:
2/3(cx+1/2) - 1/4+ 1/4 = 5/2+1/4
2/3(cx+1/2) = 11/4
1/3(cx+1/2) = 11/4 / 2
cx/3 + 1/2/3 = 11/4/2
cx/3 + 1/2*3 = 11/4/2
cx/3 + 1/6 = 11/4/2
cx/3 + 1/6 = 11/4*2
cx/3 + 1/6 = 11/8
cx/3 = 11/8 - 1/6
cx/3 = 29/24
cx = 29/24 * 3
x = 29/8 / c
x = 29/8c

For each boy, there are 5 girls
Given:
In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and
.
To find:
The
.
Solution:
If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.
We have, DC is parallel to BA and BC is the transversal line.
[Alternate interior angles]


In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.
We know that base angles of an isosceles triangle are congruent.
[Base angles of an isosceles triangle]


In triangle AOB,





Therefore, the measure of angle AOB is 120 degrees.
Answer:
Interes ganado= €59.07
Step-by-step explanation:
Dada la siguiente informacion:
300€ durante 5 años al 0.3% de interés compuesto mensual.
<u>Para calcular el valor final de la inversión y el interés ganado, debemos usar la siguiente formula:</u>
FV= PV*(1 + i)^n
Present Value= 300
i= 0.003
n= 5*12= 60 meses
FV= 300*(1.003^60)
FV= 359.07
Interes ganado= 359.07 - 300
Interes ganado= 59.07
