Answer:

Area = 138in^2

Step-by-step explanation:

Given

L = 9; W =3; H =3\frac{1}{2}

Required

The surface area

This is calculated as:

Area = 2(LW + LH + WH)

So:

Area = 2(9*3 + 9*3\frac{1}{2} + 3*3\frac{1}{2})

Area = 2(27 + 31\frac{1}{2} + 10\frac{1}{2})

Area = 2*69

Area = 138in^2

Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 3
Inessa05 [86]

Responder:

2560

Explicación paso a paso:

Dado lo siguiente:

Precio del automóvil = 60000

Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000

Saldo = (60000 - 12000) = 48000

La empresa cobra un interés simple del 12% cada 6 meses

Periodo de pago = 30 meses / 6 = 5 periodos

Interés simple: p * r * t

= 48000 * 0,12 * 5 = 28800

Por lo tanto, monto total a reembolsar, incluidos los intereses:

Balance + 28800; 48000 + 28800 = 76800

El reembolso mensual es fijo;

Por lo tanto,

76800/30 = 2560

Elodia [21]

Answer:

C) 366 days

Step-by-step explanation:

Capital gains taxes are classified into:

  1. Short term capital gains which are taxed at the same marginal tax rate than ordinary income. Any investment held for one year or less is subject to short term capital gains.
  2. Long term capital gains which are taxed at a generally lower tax rate, e.g. 0 - 15% - 20%. An investment must be held for more than one year to be considered a long term capital gain.

<u>Use two points to find the slope:</u>

  • (-4, -1) and (0, -3)

<u>Slope formula:</u>

  • m = (y2 - y1)/(x2 - x1)

<u>Value of the slope:</u>

  • m = (-3 - (-1))/(0 - (-4)) = -2/4 = -1/2
