If maria winks exactly 5 times every minute and she sleepsexactly 8 hours a day, how many times does maria wink everyday?

She winks 192 times every day.

This is just basic arithmetic.

In a day, we have 24 hours.

Now, 60 minutes make an hour.

Thus,

Number of minutes in a day = 60 × 24 = 1440 minutes

She sleeps 8 hours a day.

This is same as; 8 × 60 = 480 minutes

Thus, total time she is awake in a day = 1440 - 480 = 960 minutes

She winks every 5 minutes.

Thus, number of winks = 960/5 = 192 winks

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
