The numbers 1, 2, 3, 4, 5, and 6 are placed in a line. How many even numbers can be made from these digits?
fiasKO [112]
<h3>Answer:    360</h3>

==========================================================

Explanation:

We have 3 even values (2,4, and 6) so this is the number of choices we have for the units digit. Recall that a number is even if the units digit is 0,2,4,6 or 8.

Once we have the units digit selected, we have 6-1 = 5 choices for the first slot, 6-2 = 4 choices for the second slot, and so on until we get down to 6-5 = 1 choice for the fifth slot

We could write it out like this

  • slot one = 5 choices
  • slot two = 4 choices
  • slot three = 3 choices
  • slot four = 2 choices
  • slot five = 1 choice
  • slot six = units digit = 3 choices

Multiply those values out: 5*4*3*2*1*3 = 360

There are 360 different even numbers possible.

A peregrine falcon can fly 322 kilometers per hour. How many meters per hour can the falcon fly
lianna [129]
322kmh x1000= 322,000 meters per hour
That is the relationship between km and m
Because we are turning bigger units into smaller we the number will increase.

example   2 wks = 14 days  two became 14 - it increased

A plane takes off at an angle of elevation of 15 and travels in a straight line for 3,000 meters. What is the height of the plan
Gala2k [10]

That's a right triangle with hypotenuse 3000 and the height y is the side opposite the elevation angle of 15 degrees.

y = 3000 \sin 15^\circ


We can actually compute \sin 15^\circ exactly but I won't bother.

y \approx 776 \textrm{ feet}
