2.75 I think
I hoped this helped
C - is a hypotenuse,
so we can use Pythagorean theorem.
c² =a² +b²
c² = 8²+12²=64 + 144 = 16*4 +16*9=16(4+9) =16*13
c²=16*13
c=√(16*13)=√16*√13=4√13
c=4√13
Answer C. 4√13
J = 20
it's very easy, aren't you really able to find that by yourself?
30% in a decimal is .30. Take .30 and multiply it by 365. You get the answer of 109.5. Then, subtract 365 by 109.5 which equals 255.5.
I do not know if this is the right answer but I tried
225 + 225*0.35 = x
225 + 78.75 = x
303.75 = x
