A is your answer
We can cross multiply using x/70=30%/100
Solving it we get:
100x=2100 (70 times 30)
x=21
So we get a, 21 as your answer.
I hope this helped!
Responder:
5,52
Explicación paso a paso:
Dado lo siguiente:
Precio por kilo de papa = 1.2
Kg de papa comprada = 2.2kg
Precio por kilo de arroz = 3.7 por kilo
Kg de arroz comprado = 3.2 kg
Valor del boleto emitido para el pago = 20
Precio total de la papa:
Precio * kg comprado
1.2 * 2.2 = 2.64
Precio total del arroz:
Precio * kg comprado
3.7 * 3.2 = 11.84
Cantidad total gastada = (precio total del arroz + precio total de la papa)
2.64 + 11. 84 = 14.48
Cambio pendiente = 20 - 14.48 = 5.52
The value of y would be C) 38 degrees because if the floor and the top of the stair are parallel, then that makes the diagonal line a transversal, therefore the 38 degree angle and y are alternate interior angles.
In 180 degree rotation, magnitude remains same, and sign of the coordinate changes. So, the coordinates of Pre-image would be: Z (-9, -2)
In short, Your Answer would be: Option B
Hope this helps!
