Answer: x^2+5x+6
Step-by-step explanation:
Percentage means 'out of 100 100 '. Convert the decimal number to a fraction by shifting the decimal point in both the numerator and denominator. Since there is 1 1 number to the right of the decimal point, move the decimal point 1 1 place to the right.
Answer:
i have no idea lol make it more clearer
So it should be y = 2*2^x
Where x is the time and y is the final width after x minutes
The appropriate price is
(150 ft)*(($0.15/in)*(12 in/ft)) = $270.00
Apparently, the factor (12 in/ft) was left out of the computation, so the charge was for $0.15 per foot.
a) The price was not correct. The correct price was $270.00
b) The mistake was charging by the foot rather than by the inch.
