Answer:
73.2km
Step-by-step explanation:
first you have to decompose 46 km into y and x components.
x=sin40°*46km
x=0.64*46km
x=29.44km
y=cos40°*46km
y=0.76*46km
y=34.96
now you add the y components together
32+34.96=66.98
finally use Pythagorean thereom to find the resultant vector.
a*a+ b*b=c*c
66.98*66.98+29.44*29.44=c*c
c*c= 4486.3+866.7
c=√5353
c=73.2 km this is the approximate value
Answer:
The easiest way is: You can change them to decimals, subtract and then change back to fraction
Step-by-step explanation:
166 is the total of how many jumps they made all together
Answer is
C=4+2.75b
Step by step explanation
You just need to read the question carefully if you don’t get it
100/5 = 20
20/4 = 5
Therefore, 20x5, or vice versa, 5x20. =^)
