Answer:
15 feet
Step-by-step explanation:
The diagonal of a 9 ft by 12 ft rectangle is given by the Pythagorean theorem as ...
d = √(9² +12²) = √225
d = 15 . . . . feet
The banner should be 15 feet long to match the length of the door diagonal.
Answer:
A ≈ 153.1 units²
Step-by-step explanation:
area (A) of rectangle is
A = length × breadth = 16 × 8 = 128 units²
The diameter of the circle is 8 , then radius = 8 ÷ 2 = 4
area of semicircle = × πr² ( r is the radius )
= × π × 4²
= × π × 16
= 8π
Then area of figure = 128 + 8π ≈ 153.1 units² ( to the nearest tenth )
This question is worded slightly strangely but I believe I understand it.
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
<span>Then you can subtract 4x on the top by 4x on the bottom to eliminate it. </span>
