3679578475848 that's the answer
Answer:
42%
Step-by-step explanation:
You have essentially A fraction, 21/50, which gives you a decimal of 0.4 the 2, or 42%
Answer:
43.94?
Step-by-step explanation:
I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.
cos(∅) = 
cos(∅) = 0.72
cos⁻¹(0.72) = 43.94
I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)
Let's get the data out of the problem:
d = 38.4 km
t = 6 h
Now, we can apply in this equation and find his speed:
v = d / t
v = 38.4 / 6
v = 6.4 km/h
Joe has a speed of 6.4 km/h.
Hope it helps.
