Answer:
Jiao's total swimming time is 59.73 seconds
Step-by-step explanation:
i) Ava took 31.49 seconds to finish her first lap.
ii) Ava took 30.03 seconds to finish her second lap.
iii) Therefore Ava took 31.49 + 30.03 = 61.49 seconds to complete her two laps.
iv) Jiao finished her two-lap swimming race 1.76 seconds before Ava.
v) Jiao's total swimming time = 61.49 - 1.76 = 59.73 seconds
Answer:
A
Step-by-step explanation:
Because the mean has to describe
You will need to use the Pythagorean Theorem and plug in the varibles. The rope is the hypotenuse of the right triangle formed, and the 40ft water is the vertical leg, which leaves the ocean floor to be the horizontal leg.[a^{2}+b^{2}=c^{2}\] \[a^{2}+40^{2}=140^{2}\] Then solve for a. \[a^{2}=18000\] \[a=134.164\]
Y=-X
This is because as the value of x goes up, the value of y goes down
