Given:
28/36 ratio
annual income: 86,250
28+36 = 64
28/64 * 86,250 = 0.4375 * 86,250 = 37,734.375
36/64 * 86,250 = 0.5625 * 86,250 = 48,515.625
28/36 ⇒ 37,734.375/48,515.625
Answer: The answer is D
Step-by-step explanation:
P=4s
s=p/4
a=s^2, using s found above
a=p^2/16, we were told that p=40 so
a=40^2/16
a=100 in^2
7) 2-9= -7 because, if you have two cookies and promised nine friends cookies, you would still owe 7 friends cookies or -7
8) -3 - (-4)= 1 because you owe 3 friends cookies, then you get 4 cookies and have one left over
9) 11 - (-12)= 23 because a negative plus a negative is a positive
