$21.50 - $4 = $17.50 If you start with $21.50, subtract the $4 entrance fee, you have $17.50 left to spend on rides. To figure out how many rides you can go on, divide $17.50 by $2.50. You can go on 7 rides. Here's the equation:
(21.5-4)/2.5=amount of rides
(21.5-4)/2.5= 7 rides
Answer:
2
Step-by-step explanation:
x2+3x=6
Step 1: Subtract 6 from both sides.
x2+3x−6=6−6
x2+3x−6=0
For this equation: a=1, b=3, c=-6
1x2+3x+−6=0
Step 2: Use quadratic formula with a=1, b=3, c=-6.
x=
−b±√b2−4ac

The store sells a product for 40% more than the what they buy it for.
40% is 0.40 in decimal because all percents are out of 100 (divide by 100)
300×(1+0.40)=$420
Answer:
8 potential winners ( 444, 446, 644, 464, 466, 646, 664, 666)
Step-by-step explanation:
To alter the odds the balls numbered 4 and 6 werent injected with liquid and hence they will float making it certain for their selection and determination as the winning digits. The potential of the winning numbers are (2)^3=8.
Since 4 and 6 ain't filled with liquid, they would be selected and determine the digits in the winning numbers in 8 ways ( 444, 446, 644, 464, 466, 646, 664, 666). The potential winning number is among them.
