You have to look up how many miles are in one km.
You need that number to solve this problem.
<u> 1 km = about 0.62137... mile</u> (rounded)
160 km = (160) x (0.62137) = <em>99.419 miles</em> (rounded)
14 and 15
14^2 = 196
15^2 = 225
225+196 = 421
9514 1404 393
Answer:
160°
Step-by-step explanation:
The path is a triangle with side lengths 796, 1054, and 411 meters. The turn is opposite the short side. The interior angle of the triangle at that point can be computed using the law of cosines. If we label the sides a, b, c, respectively, then ...
c² = a² + b² - 2ab·cos(C)
C = arccos((a² +b² -c²)/(2ab)) = arccos(1575611/1677968) ≈ 20.116°
The external angle at the buoy is 180° -20° = 160°.
The jet skier's turn was about 160°.
Answer:
D is the correct answer.
Step-by-step explanation:
D is the correct answer.
When you add fractions, the answer is always rational.
1/5+-2/3= 3/15-10/15 = -7/15
Answer:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by
2.1
gives the next term. In other words,
