Answer:
El perímetro de un terreno rectangular mide 48 m . Calcula sus dimensiones si el largo es el doble que el ancho.
Respuesta:
De largo mide 16m
De ancho mide 8m
Explicación paso a paso:
Perímetro = número de lados multiplicado por longitud del lado.
Formula: P = 2(a + b) o P = 2b + 2h
Donde: P = Rectángulo del perímetro
a y b = Longitudes de lados
Asignamos las variables:
Largo = 2x
Ancho = x
Utilizamos la formula:
2(x) + 2(2x) = 48
2x + 4x = 48
6x = 48
x = 48/6
x = 8m (ancho)
2x
2(8)
16m (largo)

Answer:
D) (x+2) (x+2)
Step-by-step explanation:
Answer:
2/5 or 40%
Step-by-step explanation:
.40 is 40 hundredths or 40/100
40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5
Percentages are fractions out of 100 so 40/100 would be 40%.
Your neighbor will let you take water from the well on his claim,
charging you $.05 a quart.
If 'x' is the number of quarts you take from his well on Tuesday, then
'y' is the amount of money you owe him before the sun goes down.
Answer:
n(B U S) = 75
Step-by-step explanation:
Explanation:-
<u>Probability</u>:-
P(E) = 
Let 'B' be the event of having twelve year old brother
Let 'S' be the event of having twelve year old sister
given data P(BUS) = 0.25
given total survey n(survey) = 300
we have to find the value is n(BUS) =?
we will use probability definition we get, P( BUS) =
substitute given values, we will get solution
after cross multiplication , we get
n(BUS) = 0.25 X 300
n(BUS) = 75
