4 0

Answer:

1, 5 and 6.

Step-by-step explanation:

The sides of this triangles has lengths in the ratio x : √3x : 2x where 2x is the hypotenuse.

When C = 30,  the side AB is the small leg  (=x).

When B = 90, the hypotenuse is  AC ( =2x).

When A =  60, the larger leg is BC (=√3x).

1.  AB = 4, BC = 4√3 :- Are possible legs.

5 AB = 7, AC = 14. :-  AB = small leg, AC = hypotenuse.

6. AB = 11, BC = 11√3:-   AB = small, BC = larger leg.

A restaurant has 75% of its tables being used. Which ratio compares the used tables with all the tables in the restaurant?
Bogdan [553]
75%=75/100=75:100=3/4

4-3=1

1/4=tables not used.

1/4=25/100=25:100

So....25:75 = not used tables : used tables
