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.
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%
100-700 usd
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.
80-100 is normal B/S
