Answer:
6,5
Step-by-step explanation:
1 dollar 30 cent = 130 cent
20 copies=130
1 copy=130/20=6,5
1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700.
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.
Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° =
, sin30° =
, then
cos30° =
=
=
( cross- multiply )
2x = 20
×
= 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° =
=
=
( cross- multiply )
2y = 20
( divide both sides by 2 )
y = 10
The first one because .33 is not repeating .33 33 33 33 33 and .3 is .3 3 3 3 3 3
So that's why it's the first one.
Hope this helps!
