Answer:
465
Step-by-step explanation:
Since we are looking for the the number of combinations to have 2 different flavors in the ice cream, we can use the formula for combination.

Our variables are:
n = 31
k = 2




The number of possible combinations of having 2 different flavors out of 31 different flavors is 465.
2. Because if 1/3 + 2/3 is 1 then 1+1=2
Answer:
452 km is 452,000 meters
Step-by-step explanation:
This question can be solved using a rule of three.
1 km is 1000 meters.
How many meters are 452 km?
1km - 1000m
452km - xm
x = 1000*452
x = 452,000
452 km is 452,000 meters
So we know that:
City A is -96ft in elevation
City C is -24ft in elevation
City D is (1/4C)ft in elevation.
So, knowing this we can make an equation: 1/4•-24/1=-24/4=-6
So from that, we get the result of City D being -6ft in elevation, or 6ft below sea level.
