Answer:

630

Step-by-step explanation:

Use the Fundamental Counting Principle to find the total number of possible combinations.

Car Models = 10

Exterior colors = 7

Interior colors = 9

=> 10 * 7 * 9 = 630

Hence the total number of combinations possible would be 630 outcomes.

Please Help, I keep getting the wrong answer every time. The length of a rectangle is twice its width. The perimeter is 60 ft. F
MrRissso [65]

Answer:

This is probably wrong. But i hope this helps anyways

Step-by-step explanation:

If the perimeter is twice its width, and the perimeter is 60. That means the whole length of the shape youre looking at is 120. (60•2) we can assume that this shape has 4 sides. 60/4.  Thats 15. So the sides are 4 ft. The length is at the top and bottom is 15. 15•4 = 60. There ya go
