Answer:
4
Step-by-step explanation:
you need 4 halves to make 2 whole!
12% of 68 is 8.16. In order to find this answer you must change 12% into a decimal (.12) and then multiply by 68. (68×.12=8.16).
The 9 is higher than 5, so the 3 will round up to 4
502.644
The standard equation of the circle is:
(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...
so
30.
(x-2)^2+(y-7)^2=16
31.
We need to find the radius...(I'll just use the Pythagorean Theorem)
r^2=6^2+8^2
r^2=36+64
r^2=100 (so the radius is 10) and its center is (-6,-8) so
(x+6)^2+(y+8)^2=100
