A = C = 180 - B = 80 So A + C = 160
b^3 - 25b^2 - 4b + 100 = 0 b = 25 or b = -2
that would be a solid B
40/50 reduces to 4/5 which would be 80 percent thus making it a B
The area is A and the parameter is P.Two sides of the garden must be length a and the other two sides must be length b.ab = A = 1402a + 2b = P = 48ab = 140 and2a = 48 - 2bdividing bother sides by 2:a = 24 - bPlugging in this formula for a in terms of b into the equation for area we can conclude that:(24 - b)b = 14024b - b2 = 1400 = b2 - 24b + 140This can be factored as such:0 = (b - 14)(b - 10)therefore b = 10, 14.Logically, b can only be either 10 or 14, and amust be the other value.
100-80 a b = 20
p/b=r/100 16/b=80/100 (16/80)100=b b=20 Check your work: 80% of 20 is 20x.8=16, work checked
question: find the percentage A is of B or, 7 (A) is what percente of 35 (B) (B-A)/B x 100 =C. then subtract C from 100 B-A 35-7=28 /B 28/35=0.8 x 100 =C 0.8 x 100=80 - C 100-80=20. so, 7 is 20 percent of 35
It is 80% If your class or school grades: 90-100% =A, 80-89% =B. Then you have a B. A low B.
The 130 reading is pre high blood pressure, the 65 is ideal. The ideal blood pressure is between 90 and 120 over 60 to 80
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
B. It's the equivalent of receiving 85 out of 100, which falls in the middle of the B, which is 80 to 89. To find the answer, you take 8.5 and multiply it by 10 to get 85.
Depends on how many were possible. For instance on a test of 100 questions 80% would be a B.
If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.
Assume that B is 100% A therefore is 140% —> B + 40% C therefore is 120% —> B + 20% Therefore A : C = 140 : 120 Therefore A exceeds C by 16.67%

To find A as a percentage of B, calculate 100*A/B To find A as a percentage change from B, calculate 100*(A/B -1) or, equivalently, 100*(A - B)/B. B should be positive else you will need great care in interpreting the result.
