Answer: 2 1/5 partes de torta
Step-by-step explanation:
Para contestar esta pregunta debemos sumar cada parte de torta:
0.7+9/12+6/8 =
Convertimos las fracciones en decimales, para tener todos los valores expresados de la misma forma. Dividiendo:
9/12=0.75
6/8=0.75
Sumamos
:
0.7+0.75+0.75 = 2.2 partes = 2 1/5 partes
En conclusión, Carolina y sus amigos comieron 2 1/5 partes de torta.
Hello,
Let's place the last digit: it must be 2 or 4 or 8 (3 possibilities)
It remainds 4 digits and the number of permutations fo 4 numbers is 4!=4*3*2*1=24
Thus there are 3*24=72 possibilities.
Answer A
If you do'nt believe run this programm
DIM n(5) AS INTEGER, i1 AS INTEGER, i2 AS INTEGER, i3 AS INTEGER, i4 AS INTEGER, i5 AS INTEGER, nb AS LONG, tot AS LONG
tot = 0
n(1) = 1
n(2) = 2
n(3) = 4
n(4) = 7
n(5) = 8
FOR i1 = 1 TO 5
FOR i2 = 1 TO 5
IF i2 <> i1 THEN
FOR i3 = 1 TO 5
IF i3 <> i2 AND i3 <> i1 THEN
FOR i4 = 1 TO 5
IF i4 <> i3 AND i4 <> i2 AND i4 <> i1 THEN
FOR i5 = 1 TO 5
IF i5 <> i4 AND i5 <> i3 AND i5 <> i2 AND i5 <> i1 THEN
nb = ((((n(i1) * 10) + n(i2)) * 10 + n(i3)) * 10 + n(i4)) * 10 + n(i5)
IF nb MOD 2 = 0 THEN
tot = tot + 1
END IF
END IF
NEXT i5
END IF
NEXT i4
END IF
NEXT i3
END IF
NEXT i2
NEXT i1
PRINT "tot="; tot
END
First, do 110-30 (You'll get 90). Then, divide 90 by 2 (You'll have 45). Finally, take 45 from 350. Your final answer should be 305.
Answer:
x would equal 8, not sure but I think y would be 16
