When he buys lottery tickets he spends $10, he gets $7 back in winnings so he actually spends $3 on lottery tickets.
17.01+3=20.01
100-20.01=79.99
He would receive $79.99 in change
Answer:
16% of people are wearing hats
Step-by-step explanation:
500-80=420
420/500 = 42/50

100-84=16; 16% were wearing hats
Answer:
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (-3,5).
Point on the circle is (x,y) = (1,8)
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (-3,5) and (x,y) = (1,8) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(1 - (-3))^2 + (8 - (5))^2 = r^2
(4)^2 + (3)^2 = r^2
16 + 9 = r^2
r^2 = 25
r = 5
