Using a straightedge and compass, construct the perpendicular bisector of FG

Mathematics

Maurinko [17]4 years ago

This is how I learned.
Place a point above the line segment.  Open the compass so that you can create arcs on the line segment.  One arc should intersect on the right side, the other on the left.  Name these points (A and B, for example). Move the compass to one point.  Use the same radius in the compass<em /><em /> and make an arc below the line segment.  Then move the compass to the opposite point and make another arc (with the same radius).  The two arcs should intersect.  Draw a line from the point above the line segment to the new intersection and you have your perpendicular bisector.

A theater can seat 273 people. The number of rows is 8 less than the number of seats in each row. How many rows of seats are the
artcher [175]
R * s = 273
r = s - 8.....s = r + 8

r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0

r - 13 = 0
r = 13

r + 21 = 0
r = -21.....extraneous solution...not ur answer

r = 13
s = r + 8 = 13 + 8 = 21

so there are 13 rows.....each row containing 21 seats

. A square picture frame occupies an area of 112 ft2 . What is the length of each side of the picture in simplified radical form
saw5 [17]
Recall that a square is just a rectangle with all sides equal.

and the area of a rectangle is just length * width.

\bf \textit{area of a rectangle}\\\\&#10;A=length\cdot width\quad &#10;\begin{cases}&#10;length=x\\&#10;width=x\\&#10;A=112&#10;\end{cases}\implies 112=x\cdot x\implies 112=x^2&#10;\\\\\\&#10;\sqrt{112}=x\implies \sqrt{16\cdot 7}=x\implies \sqrt{4^2\cdot 7}=x\implies 4\sqrt{7}=x

The difference of two numbers is 16 and the sum of their squares is 130. What are the numbers.
Korvikt [17]
x - y = 16
x^2 + x^2 = 130

----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108
