A rectangle fence was installed yesterday around gemma's house. The students from the near high school were asked to find out the dimensions of the rectangular fence as part of their exam. They asked one of the workers the perimeter of the fence and they were given 350 meters. What is the dimensions of the rectangular fence?
For a project in his Geometry class, Mamadou uses a mirror on the ground to measure the height of his school’s football goalpost. He walks a distance of 13.75 meters from his school, then places a mirror on flat on the ground, marked with an X at the center. He then steps 2.6 meters to the other side of the mirror, until he can see the top of the goalpost clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.75 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.

The spacing of the frets on the neck of a classical guitar is determined from the equation d=(21.9)(2)(20−x)12/, where x = the fret number and d = the distance in centimeters to the x-th fret from the bridge. *Determine the distance from the bridge for three consecutive frets. Round each answer to 3 decimal place. For example, you can calculate the distance from the bridge for the 4th, 5th and 6th fret.*
Morris is designing a new sign for his ice cream shop to be placed by the exit from a nearby highway. The sign needs to be big. Really big. He plans on making the height of the bottom triangle 3 times the height of the semicircle on top of having a total area of 74 square feet. If the county will not allow any signange taller than 15 feet, will Morris be allowed to put up his cone?
For a project in her Geometry class, Nicole uses a mirror on the ground to measure the height of her school’s football goalpost. She walks a distance of 9.65 meters from the goalpost, then places a mirror flat on the ground, marked with an X at the center. She then walks 4.95 more meters past the mirror, so that when she turns around and looks down at the mirror, she can see the top of the goalpost clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.65 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.
For a project in her Geometry class, Chloe uses a mirror on the ground to measure the height of her school’s football goalpost. She walks a distance of 10.65 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.2 meters to the other side of the mirror, until she can see the top of the goalpost clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.75 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.
