Answer:
450
Step-by-step explanation:
We know that Cole did jump rope for 7 1/2 minutes.
In one minute there are 60 seconds. So we know that for each minute there is a 60 in it.
So, 7 x 60 = 420 then a half minute is thirty seconds (we know this because half of sixty is thirty.)
So we simply add 30 to 420 getting 450.

In this complex number, assuming that the equation actually is <span>18- √-25</span>, the real part is already simplified. However, the imaginary part can be simplified by taking out "i" from the root using the relation i = <span>√-1. This is done below:
18 - </span><span>√-25
18 - </span>√(-1)(25)
18 - 5i
From the choices, the correct answer is 18 - 5i.
