Answer:

El hijo solo tardará 3 horas en arar el campo

Step-by-step explanation:

Aquí, se nos dice que ambos pasan dos horas para arar el campo mientras que el padre solo pasa 6 horas.

Queremos saber el tiempo que pasará el hijo si va a trabajar solo

Sea el área del campo x

La tasa de trabajo de ambos es x / 2

La tasa de trabajo del padre será x / 6 Deja que el tiempo que pasa el hijo sea y La tasa de trabajo del hijo es x / y

Sumando la tasa de trabajo del padre a la del hijo da la tasa de trabajo total de ambos Por lo tanto;

x / 6 + x / y = x / 2

Despegar x 1/6 + 1 /y = 1/2

1 / y = 1/2 - 1/6

1 / y= 1/3

entonces y = 3

El hijo solo tardará 3 horas en arar el campo.

Purchased a living room set for $3,800 at 11% add on interest for 3 years , whats the nearest tenth of a percent for the loan de
ELEN [110]

Answer:

The loan amount after 3 years is $ 5,196.88

Step-by-step explanation:

Given as :

The principal amount for room loan = $ 3,800

The rate of interest applied = 11% compounded annually

The time period of loan = 3 years

Let The Total loan amount = $ A

Now,<u> From Compounded method :</u>

Amount = Principal × (1+\dfrac{\textrm rate}{100})^{\textrm time}

or, A = $ 3,800 × (1+\dfrac{\textrm 11}{100})^{\textrm 3}

or, A = $ 3,800 × (1.11)³

or,  A = $ 3,800 × 1.3676

∴ A = $ 5,196.88

So, Amount after 3 years = A = $ 5,196.88

Hence The loan amount after 3 years is $ 5,196.88 Answer

QUIZ 2 - GEOMETRY
borishaifa [10]

Answer:

y = 5x - 13

Step-by-step explanation:

Slope of the line 5x + y = 2

Since, required line is parallel to the given line.

So, slope of required line = 5 (Parallel lines have same slope)

y - (- 3) = 5(x - 2)

y + 3 = 5x - 10

y = 5x - 10 - 3

y = 5x - 13
