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.
Answer:
Therefore, x is 1 and 2.
Step-by-step explanation:
As you plot both equations on the same graph, you will get something like this, shown in the graph.
Then, you have to find the x solutions where they intersect.
So, both equations intersect at x = 1 and 2.
The answer is 35.
We have the ratio 7/9 cross multiply with x/45
7*45 = 315
315/9 = 35
Step-by-step explanation:
Sa = b • h/ 2 = 5 • 11 /2 = 55/2 = 27.5ft²
