It helps to draw a picture so you can visualize it better.
For the rug, since the area = 144, what two numbers multiplied give you 144? You might already know that 144 is a perfect square, so 12 x 12 = 144. 12 is the length of each side of the rug.
√144 = 12
12 + 3 = 15. (Add 3 because the rug only covers a portion of the floor. The entire floor = the length of the rug + the part that isn't covered)
15 x 15 = 225 ft squared (Multiply both sides of the floor to get the area.)
225 ft squared - 144 ft squared = 81 ft squared <-- your answer
Answer:
240π
Step-by-step explanation:
Turbine blade that was 24 inches long is the radius of the circle the bug travels.
So the Circumference is = 2rπ = 2*24*π = 48π
The bug held on for 5 rotations. so the distance that the bug travels = 5*48π = 240π
To solve the inequality, you isolate the variable on one side using transformations that produce equivalent inequalities, which have the same solution(s). Solve x+5≥3. Graph the solution. The solution is all real numbers greater than or equal to -2.
