So, 932.4miles (.75)=699.3miles are the miles that she wants to drive by the start of three days. so each day is 25% because of 75%/3=25%
In two days it will be 50% so, .50(932.4miles)=466.2 miles is the answer.
So, you want 4 of each kind.
Pick any set of 4 from each kind, and then there will be 12! ways to play them.
21C4 * 13C4 * 25C4 * 12! = 2.593*10^19
Answer:

Step-by-step explanation:
37/15 or 2 7/15
Answer:
There are 81 girls.
Step-by-step explanation:
First, take what we know and find how many people 1 in the ratio is:
54 / 2 = 27
(in this problem) 1 = 27
Now find how many girls are at the dance by multiplying by three:
27 x 3 = 81
There are 81 girls at the dance.
X=-b+-sqrt (b^2-4ac)/2a
x=-11+-sqrt (11^2-4(8)(-300)/16
x=-11+-sqrt (121+9600)/16
x=-11+-sqrt (9721)/16
x=-11+-98.6/16
x=5.48 or x=-6.85
