I buy a bed which normally costs £270 on a scheme where the price of the bed is increased by 60% but I only pay back £18 a month
Hitman42 [59]

Answer:

it would take 2 years or 24 months

Step-by-step explanation:

60 percent of 270 is 162 add that to 270 and you get 432 divide that by 18 because that's what you're paying every month and you get 24 which is the numbe rof months it will take you to pay the bed off.

To cross check we can multiply 18 and 24 and you get 432.

torisob [31]

Answer:

Se obtuvo $ 448 de ganancia por la venta de donas.

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Step-by-step explanation:

1) <em>¿Cuanta ganancia se obtuvo en la venta de donas?</em>

La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:

C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)

C = 448\,USD

Se obtuvo $ 448 de ganancia por la venta de donas.

2) <em>¿Cuanta ganancia se obtuvo en la venta de bolillos?</em>

La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:

C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)

C = 280\,USD

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Which statement explains the lines 2x+y=4 and y=1/2x+4 are related
Inessa [10]

Answer:

The lines are perpendicular

Step-by-step explanation:

we have

2x+y=4

isolate the variable y

y=-2x+4 ----> equation A

The slope of the line A is m=-2

y=\frac{1}{2}x+4 -----> equation B

The slope of the line B is m=\frac{1}{2}

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

In this problem

The slopes of line A and line B are opposite reciprocal

therefore

The lines are perpendicular
