Peter was told by his teacher that he needed to measure the height of the building in which his classroom was located. He backs

away from the building and places a mirror an the ground between him and the wall When he can see the top of the building in the mirror, Peter is 2 feet 9 inches away from the mirror and the mirror is 11 feet away from the wall of the building. Peter knew his eye level was exactly 5 ft 6 inches off of the ground, so he was able to calculate the height of the building. How tall is the building in feet?

Which set of measurements can represent the lengths of a triangle's sides?
zepelin [54]
Triangle, not a triangle, not a triangle, triangle

Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.[

George has $3.71 in pennies,nickels dimes and quarters in his pocket. He has twice as many dimes as nickels, two more nickels th
FromTheMoon [43]
<span>pennies = 0.01 $
 nickels = 0.05 $
 dimes = 0.1 $
 quarters = 0.25 $
 We must write the system of equations that best suits this problem and solve it:
 Let:
 x = pennies
 y = nickels
 z = dimes
 w = quarters
 Writing the equations
 0.01x + 0.05y + 0.1z + 0.25w = 3.71
 I have twice as many dimes as nickels
 z = 2y
 two more nickels than quarters
 y = w + 2
 three fewer pennies than three times the number of nickels
 x = 3y-3.
 Solving the system of equations:
 x = 21
 y = 8
 z = 16
 w = 6
 answer
 He has
 21 pennies
 8 nickels
 16 dimes
 6 quarters
