Answer:
18 meters by 9 meters (or 9 meters by 18 meters)
Step-by-step explanation:
lets say the dimensions are x and y. we have x*y=162, and 2x+2y=54. from the second equation we have x+y=27 so y=27-x. plug this into the first equation to get x(27-x)=162 or -x^2 + 27x = 162. x^2 - 27x + 162 = 0. simplify to get (x-18)(x-9)=0. so x=18 or x=9. when x=18, y=9, when x=9, y=18 so the dimensions are 18 by 9 meters
Answer:

Answer:
Multiply the number of attempts by the percentage:
75 attempts x 0.65 = 48.75
Round up to 49 shots.
To find out whether n = 112 is a solution to the inequality, plug 112 for n into the inequality and simplify.
10 + n/28 > 14
10 + 112/28 > 14
10 + 4 > 14
14 > 14
This reads "fourteen is greater than fourteen," which is false.
n = 112 is NOT a solution to the inequality 10 + n/28 > 14.
