The sin ratio is the side opposite the reference angle over the hypotenuse. If Z is our reference angle, then the side opposite it has a length of 32. The hypotenuse has a length of 40. Therefore, the sin of Z = 32/40. We will reduce that to sin Z = 4/5. First choice above.
Answer:
It took him 13.8 sec to run
Step-by-step explanation:
Time to spin 6 times can be represented mathematically by "6 s". Then the total time it took him to get to the tree (which must be the addition of the time spinning plus the time running) is:
6 s + r = 21 sec
since each spin takes him 1.2 sec, then we have:
6 (1.2 sec) + r = 21 sec
7.2 sec + r = 21 sec
r = 21 sec - 7.2 sec
r = 13.8 sec
Answer:You are just converting a larger unit into a smaller unit easy peasy
Step-by-step explanation:
Answer:
(-8, -21)
Step-by-step explanation:
y=2x-5
3x+3=y
------------
2x-5=3x+3
2x-3x-5=3
-x-5=3
-x=3+5
-x=8
x=-8
y=2(-8)-5=-16-5=-21
Answer: x=-8, y=-21.
