Answer:
1:3
Step-by-step explanation:
10 red cards, 10 black cards, and 20 blue cards
We want the ratio of red to other cards
red : blue and black
10 : 10+20
10 : 30
Divide each side by 10
10/10 : 30/10
1:3
Simple...there'a a LOT of combinations...
so to simply solve this;there is 5 appetizers, 7 entrees and 3 desserts....
Just take 5*7=35
and
35*3=105
Thu,s there is 105 combinations possible to make.
Thus, your answer, D.
All you do is multiply 15 and 6 you get 90. then divide 90 by 9 and you get 10.
17.4736843 or 17 remainder 45
The answer is 25 because of the Pythagorean theorem. 49+576=625 625 squared=25
