so that
which translates to a speed of about 16.5 km/hr in a direction of 25.48º South of East.

Simplify your answer as much as possible.
Step-by-step explanation:
8.5cm · 250,000 = 2,125,000cm
1m = 100cm therefore 1cm = 0.01m
2,125,000cm = 2,125,000 · 0.01 = 21,250m
1km = 1,000m therefore 1m = 0.001km
21,250m = 21,250 · 0.001km = 21.25km
Answer: 21,250m = 21,25km
Answer:
160 quarters
Step-by-step explanation:
multiply 40 by 100, because there are 100 cents in a dollar, and divided 4,000 by 25, because there are 25 cents in a quarter
Cost to buy one = $ 10
Cost to buy two without discount = $ 20
Cost to buy two with the discount = 10 + (1/2 *10) = 15
True percent discount on the dog food = 5/20 x 100 % = 25 %
