13/30, because you find the common denominator, 30.

From there, what you do is think, what times 5 is 30? (Talking about 3/5) 6! So you multiply 3 and 6, and get 18/30.  

Next, do the same with 1/6, and you get 5/30.  
Finally, subtract 5/30 from 18/30, and you get 13/30.

Hope this helps!

Lorico [155]
I would start like this: which year was the seventh AMC 8??

the first was in 1985
The second: 1986
3: 1987
4: 1988
5: 1989
6: 1990
7: 1991

so seventh AMC 8 took place in 1991.
she was then 12, so we can subtract this age from 1991:

1991-12=1979

so she was born in 1979!

You are measuring the height of a statue. You stand 17 feet from the base of the statue. You measure the angle of elevation from
olga_2 [115]

Answer:

height ≈ 31 ft

Step-by-step explanation:

The illustration below will form a right angle triangle. He is standing 17 ft away from the base of the statue.  The angle of elevation from the ground to the top of the statue  is 61°. The height of the statue can be computed below.

adjacent side of the triangle = 17 ft

opposite side = a

Using SOHCAHTOA principle

tan 61° = opposite/adjacent

tan 61° = a/17

cross multiply

a = 17 tan 61°

a = 17 × 1.80404775527

a = 30.6688118396

a ≈ 31 ft
