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
.5 inch / 50 miles = 5 inches / x miles
x = 500 miles
Answer:
1544.1 ft to the nearest tenth.
Step-by-step explanation:
We have a triangle where we have to find the hypotenuse and the opposite side to the given angle = 1200 feet.
So we use the sine function ( sin = opp / hyp).
sin 51 = 1200 / h
h = 1200 / sin 51
h = 1544.111 ft.
let us represent the question with a diagram for better understanding.
