It would be: 35+66 / 2 = 101/2 = 50.5
So, 50.5 is your answer
All you do for #4 and # 5 is plug the x values FROM THE TABLE into the equation, and see if you get the y values listed in the table. You don't, so you can see that the equations DO NOT REPRESENT THE DATA IN THE TABLE. For #6 you can see from the graph that one point on the line is (1,-2) which does represent the table of values. Looking further, as each x value decreases by 1, the y value decreases by 3, so (0,-5) makes sense too, again supporting the idea that the graph DOES represent the table of values
Answer:
Lets firts mention that the rule presented in the question does not apply for all real numbers
But, we can see that in some cases it might be true.
Let
a = 1
b = 0
√1 + √0 = 1 + 0 = 1
Likewise,
√(1 + 0) = √(1) = 1
And we see that the result is the same.
Answer:
Volume of square and rectangle:
L*W*H
square:
12*6*12 = 864 inches
rectangle:
18*8*10 = 1,440 in
Add
1,440 + 864 = 2,304 in^3
Hope this helped
Step-by-step explanation:
Answer: 11:50
Step-by-step explanation:
Ok, la manecilla de los minutos apunta al numero X.
si la ora es Y, entonces Y + X = 12:00
podemos asumir que Y es 11:y
y es la cantidad de minutos despues de las 11, es un numero entre 0 y 59 (por que una hora solo puede tener 60 minutos)
Si la manecilla de los minutos apunta al numero 6 por ejemplo, entoces:
y = 11:30 y X = 6 min
X + y = 11:30 + 0:06 = 11:36
Así funciona.
la equacion es:
y = 5*X
y tambien queremos que:
X + y = 60min
reemplazo y por lo de la equacion de arriba:
X + y = X + 5*X = 6X = 60min
X = 10
Si la manecilla apunta al 10, tenemos que:
y = 11:50 y X = 10min
y + X = 11:50 + 0:10 = 12:00
Entonces podemos concluir que la hora es 11:50.
