You go out to dinner and the bill comes to $ 34.63. how much should you tip if you want the tip to be 20.0 % of the bill? express the dollar amount to the nearest cent.

we say 692 Cents or 6.92 $

Explanation:

Total Bill comes  = $34.63

Tip want  = 20%

So , convert dollars in to cents

1 dollar = 100 cents

so, $34.63 becomes

34.63 dollar = 3463 cents

now, get 20% of 3463 cents

(3463/100) * 20 = 692.6 Cents

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.

the answers would be

the first one and the second one
