Set up a proportion where 1 over 1.68=30 over x. cross multiply so that you have x=50.4. then divide 50.4 by 6.3 to get 8 toothpicks tall.

Si al invertir $60.000 se pierde un 8% ¿A cuánto asciende la pérdida?
svetoff [14.1K]

Trabajando con porcentajes, concluimos que la pérdida es de $4800.

<h3>¿A cuánto asciende la pérdida?</h3>

Sabemos que la inversión inicial es de $60000, y de esta cantidad, se pierde un 8%.

Entonces la pérdida va a ser el 8% de $60000.

Podemos escribir las relaciones:

$60000 = 100%

x = 8%

Queremos resolver esto para x, tomando el cociente entre esas relaciones y resolviendo para x obtenemos:

x = $60000*(8%/100%) = $60000*0.08 = $4800

Así, concluimos que la pérdida es de $4800.

Schach [20]
The given set is {-1,0,1,2,3,4,5}
(notice the -2 and 6 are excluded)

the subset which contain positive factors of 5 is {1,5}

so the complement set would be
{-1,0,2,3,4) which matches with b)

Use slopes and y-intercepts to determine if the lines 10x+3y=−3 and 5x−4y=−3 are parallel.
kvasek [131]

Answer:

They are not parallel

Step-by-step explanation:

original equation

10x + 3y = -3

subtract 10x

3y = -10x - 3

divide by 3

y = -10/3x - 1

original equation

5x - 4y = -3

subtract 5x

-4y = -5x-3

divide by -4

y = 5/4x + 3/4

the slopes are not equal to each other (5/4x and -10/3x) so they are not parallel
