Nice computer my dear sir
Answer:
Step-by-step explanation:
sin(90-a)=cos
cos = angle adjacent
theta=BC/CA
Answer:
X= -1 or X= -3 . Probably the first one
Step-by-step explanation:
1. 2/100 or 1/50, as 0.02 is equal to 2 hundreths. Simplifying gets you 1/50
3. 1/2 or 50/100, as 0.50 is equal to 0.5 which is equal to 50 hundreths. Simplify to get 1/2
5. 88/100 or 44/50 , as 0.88 is equal to 88 hundreths. After simplifying, you get 44/50
Depending on your teacher, you may be told to not simplify. It depends
Answer:
The rate of current is 2.5 mph.
Step-by-step explanation:
The speed in the water when current is absent is 9 mph.
If the speed of the current is v mph then the upstream speed is (9 - v) mph and the downstream speed is (9 + v) mph.
Now, it takes 5 hours longer to travel 74 miles upstream than down stream, then we can write the equation as
⇒
⇒ 148v = 405 - 5v²
⇒ 5v² + 148v - 405 = 0
Applying Sridhar Acharya's formula we can write
(Neglecting the negative root)
⇒
mph (Rounded to the nearest 10th) (Answer)
