Answer: 16875

Step-by-step explanation:

Let the price of the washing machine be x.

Since she loses 20% in the bargain, this implies that she sold it at (100% - 20%) = 80%.

Therefore, 80% of x = 13500

0.8 × x = 13500

0.8x = 13500

Divide both side by 0.8

0.8x/0.8 = 13500/0.8

x = 16875

Therefore, the price at which she bought the washing machine is 16875 rupees.

Answer:

hence, the price of washing machine is Rs.16,875

Step-by-step explanation:

selling price of washing machine = Rs. 13,500

loss percentage = 20 %

let the cost of washing machine be Rs. x

lost= 20% of Rs. x= 20/100 × x =x/ 5

13500 = x - x/ 5

13500 = 4x / 5

x = 13500×5 /4

rs. 16875

The base fare per ride on the MTA bus or subway is $2.75, but you get a 5% discount with a purchase. A weekly unlimited MetroCar
Nikolay [14]

"13" or "more than 13" rides will make the weekly unlimited pass more cost effective. A further solution is provided below.

The given values are:

  • Base fare per ride = $2.75
  • Discount = 5%
  • Weekly unlimited Metro Card costs = $32

The Fare after discount will be:

= 2.75\times \frac{100-5}{100}

= 2.75\times \frac{95}{100}

= 2.75\times 0.95

= 2.6125 ($)

hence,

In $32, the minimum number of rides will be:

= \frac{32}{2.6125}

= 12.24

or,

= 13

Considera um quadrado de lado 2x e um rectângulo de comprimento x e largura x  2 . Qual é o valor de x para o qual as duas figu
ki77a [65]

Answer:

3 unidades de comprimento

Step-by-step explanation:

O perímetro é definido como a soma de todos os lados.

O perímetro de um quadrado de lado 2x é dado por:

Q=4*2x=8x

O perímetro de um retângulo de comprimento x e largura x² é dado por:

R=2x+2x^2

Para que ambos os perímetros sejam iguais:

R=Q\\8x=2x+2x^2\\x^2=\frac{6}{2}x\\ x=3

O valor de x é igual a 3 unidades de comprimento.

Which value of a in the exponential function below would cause the function to shrink? f(x) = a(three-halves) Superscript x Four
Natalka [10]

Answer:

Four-fifths

Step-by-step explanation:

As we know that

By multiplying the function by a constant, we may expand or shrink the function in the y-direction.

Now we have

y=a(b^{x})

if a> 1  > the function would enlarge

if 0< a < 1 > the function would shrinks

Now

For case A

a = \frac{4}{5}

0 < (\frac{4}{5} )< 1 ....... > the function would shrinks

For case B

a = \frac{5}{4}

(\frac{5}{4} )>1 .......> the function would enlarge

For case C

a = \frac{3}{2}

(\frac{3}{2} )>1 .........> the function would enlarge

For case D

a = \frac{7}{4}

(\frac{7}{4} )>1 .........> the function would enlarge

Therefore the second option is correct
