Answer: The man and the turkey cross the river, (the wolf and corn are safe together), he leaves the turkey on the other side and goes back across.
The man then takes the wolf across the river, and since he can't leave the wolf and turkey together, he brings the turkey back.
Again, since the turkey and corn can't be left together, he leaves the turkey and he takes the corn across and leaves it with the wolf.
He then returns to pick up the turkey and heads across the river one last time.
...... this is a very old riddle. lol I had forgotten about it.
Answer:
100*x + 14*y
Step-by-step explanation:
Tenemos que en el sistema decimal un número de 3 cifras se representa de este modo:
100*x + 10*y + z
También es llamado descomposición polinómica y de esta manera podremos encontrar la expresión algebraica.
Nos dicen la relación entre unidades y decenas, 4 veces mayor las unidades que las decenas, por lo tanto:
z = 4*y
Reemplazamos y nos queda:
100*x + 10*y + 4*y
reduciendo nos queda:
100*x + 14*y
Por lo tanto esta sería la expresión algebraica.
Answer: approximately 49 feets
Step-by-step explanation:
The diagram of the tree is shown in the attached photo. The tree fell with its tip forming an angle of 36 degrees with the ground. It forms a right angle triangle,ABC. Angle C is gotten by subtracting the sum of angle A and angle B from 180(sum of angles in a triangle is 180 degrees).
To determine the height of the tree, we will apply trigonometric ratio
Tan # = opposite/ adjacent
Where # = 36 degrees
Opposite = x feets
Adjacent = 25 feets
Tan 36 = x/25
x = 25tan36
x = 25 × 0.7265
x = 18.1625
Height of the tree from the ground to the point where it broke = x = 18.1625 meters.
The entire height of the tree would be the the length of the fallen side of the tree, y + 18.1625m
To get y, we will use Pythagoras theorem
y^2 = 25^2 + 18.1625^2
y^2 = 625 + 329.88
y^2 = 954.88
y = √954.88 = 30.9 meters
Height of the tree before falling was
18.1625+30.9 = 49.0625
The height of the tree was approximately 49 feets
You would need exactly 9 correct questions to get a 50%.
We can find this by multiplying the total number of questions by the percentage we are looking for.
18*50% = 9
