Answer:
283.3%
Step-by-step explanation:
5/6 equals 0.83 repeating and it already has 200% for the whole number 2
Let b= length and a=width
Area= a*b and the problem said b=2a+3 (the length is 3ft more than double the width)
Replace b into Area formula:
Area= a*(2a+3) and we know that Area=77ft from the problem, so:
77=2a^2+3a now order and equal to zero:
2a^2+3a=77 now solve this with quadratic formula and you will get so values for a: -7ft and 5.5ft as you know the dimensions could not be negative so the correct answer for "a" side is 5.5ft, for getting the b side you haeve to replace a=5.5 into b=2a+3 and you will get b=2*5.5+3= 14ft.
Finished.

Answer:
R2 > R1
Step-by-step explanation:
Here in this question, we want to select which of the relations best gives the answer.
Mathematically;
Power = Voltage * current
But current = voltage/resistance
Power = voltage * voltage/resistance
P = V^2/R
For 40 W
40 = (220)^2 * R1
R1 = 40/(220)^2
For 60 W
60 = (220)^2 * R2
R2 = 60/(220)^2
Mathematically, since we have the same denominator (220)^2 but with 60 greater than 40, that automatically translates to the fact that the value of R2 is greater than the value of R1( You can finish evaluating each of the expressions using a calculator).
