Area of a trapezoid: [(top +bottom)*height]/2
suppose the length of one base is x, then the other base is 5x-19
[(x+5x-19)*18]/2=477
[6x-19]*18=954
6x-19=53
6x=72
x=12
The longer base is 5*12-19=41
Answer:
c= 60m (nearest whole number)
Step-by-step explanation:
Please see the attached picture for full solution.
sinθ= opp/ hyp (SOH)
cosθ= adj/ hyp (CAH)
tanθ= opp/hyp (TOA)
Answer:
Precio de compra=$125.000
Ganancia= $25.000
Step-by-step explanation:
Dada la siguiente información:
Revalorización= 20%
Precio de venta= $150.000
<u>Para calcular el precio de compra, tenemos que usar la siguiente formula:</u>
Precio de compra= precio de venta / (1 + revalorización)
Precio de compra= 150.000 / (1,2)
Precio de compra=$125.000
Ganancia= 150.000 - 125.000
Ganancia= $25.000
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form 
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots
The Goldbach Conjecture is a yet unproven conjecture stating that every even integer greater than two is thesum of two prime numbers. The conjecture has been tested up to 400,000,000,000,000. Goldbach's conjecture is one of the oldest unsolved problems in number theory and in all of mathematics.
