The value is 21 Because three represents those to variables which both equal to 21.
1 kg = 2.205 pounds. So, 75 kilograms= 165.347 pounds.
Answer:
option 3
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
= 
, that is
= 
( cross- multiply )
CA × sin30° = 20 × sin45° ( divide both sides by sin30° )
CA = 
→ (3)
In 3 hours, at 10 mph, Albert travels 30 miles. In 10 minutes (1/6 hr), while his son overtakes him, he travels 10/6 miles more, placing him at 30 + 10/6 = 190/6 = 95/3 mi.
His son covers 95/3 mi in 1/6 hr, so he's moving at (95/3)/(1/6) = 190 mph.
