Answer:
735x0.01
Step-by-step explanation:
Width = x
length = x+10
Area of deck = 144 square feet
Area = length * width
144 = x(x+10)
Solving for x in a quadratic:
x²+10x = 144
x²+10x-144 = 0
Factor:
(x+18)(x-8) = 0
Solving for x:
x = 8, x = -18
Dimensions cannot be negative, therefore x = 8, only.
Length = x + 10
Length = 18
Width = 8
The answer would be a-v(2,0),domain: x E R, Range: y E (00,2]
Answer:
66.00
Step-by-step explanation:
Convert 10% to a decimal by moving the point from 10. to 0.10 (back two places) and multiply it by 50 which gives you $5, which equals the tax they payed. Now they want to tip 20% of the entire bill including tax, so convert 20% to a decimal 20. to 0.20. Now multiply .20 * 55(55 is the $50 payed in meals and the $5 payed in taxes added) And you get $11 for the tip. Add 55 +11 and there's your answer
