A 39-foot-long speaker wire is to be cut into three pieces. One piece is to be 13 feet long. Of the remaining pieces, one must b
alexira [117]
39 foot into 3 pieces
one is 13 feet
 the other pieces add up to the remaining wire
 which is 39-13=26 so
 the two remaining pieces are x and y
one must be 2 less than 3 times the other
 x must be 2 less than 3 times the y
x=-2+3y
 x=3y-2
 x+y=remaining=26
 26=x+y
 x=3y-2
 subsitute
 26=3y-3+y
 add like terms
 26=4y-2
 add 2 to both sides
 28=4y
 divide by 4
 7=y
 subsitute
 7+x=26
 subtract 7
 x=19
 19>7
 7 feet is the legnth of the shorter piece

Write a paragraph proof of the Triangle Angle Sum Theorem using the following figure. A line should pass through F as part of th
BabaBlast [244]

Answer:

Step-by-step explanation:

To prove the triangle angle sum theorem,

We will do a construction by drawing a line PQ passing through point F and parallel to line DE.

                Statements                              Reasons

1). ∠PFD + ∠QFD = 180°                     1). linear pair postulate

2). ∠QFD = ∠QFE + ∠EFD                 2). Angle addition postulate

3). ∠PFD + ∠QFE + ∠EFD = 180°       3). Substitution property

4). ∠PFD ≅ ∠FDE                               4). Alternate interior angles

    ∠QFE ≅ ∠DEF                                

5). ∠FDE + ∠DEF + ∠EFD = 180°       5). Substitution property

Hence sum of interior angles of ΔDEF is 180°.

The grades on an easy quizquiz Choose the correct answer below.
Zigmanuir [339]

Answer:

B)

Step-by-step explanation:

If it's an easy quiz, there would be a lot of students with high grades, therefore, the data set would be skewed left, the mode would be in the right side of the graph, then we would have the median and the mean would be the lower value. There would be just a few students with lower grades and this grades would pull the mean away from the median toward the left.
