Schach [20]

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

100 - 60 = 40%

then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

1 dime = $0.10

9 dimes = 9 • $0.10 = $0.90

then, find how much money kerry had:

$2.65 - $0.90 = $1.75

finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

1 quarter = $0.25

$1.75 ÷ $0.25 = 7 quarters

Show that any finite set is closed.

Alecsey [184]

If you know that a single point is closed (as a set), then any finite set is closed because they are finite unions of closed (single point) sets.

The missing measures are listed below:

$m \angle 1 = m \angle 3 = m \angle 6 = 59^{\circ}$
$m\angle 2 = m\angle 4 = m\angle 5 = m \angle 11 = 31^{\circ}$
$m\angle 7 = m\angle 8 = m\angle 9 = m\angle 10 = 118^{\circ}$

<h3>Procedure - Finding missing angles in a quadrilateral</h3>

In this question we must determine the measures of the missing angles by both geometric and algebraic means, whose procedure is presented below:

$x = 59^{\circ}$ Given
$m \angle 3 = 59^{\circ}$ Alternate internal angles
$m \angle 11 = 31^{\circ}$ Complementary angles
$m \angle 4 = 31^{\circ}$ Alternate internal angles
$m \angle 6 = 59^{\circ}$ Isosceles triangle
$m \angle 9 = 62^{\circ}$ Sum of internal angles in a triangle
$m \angle 10 = 118^{\circ}$ Supplementary angles
$m \angle 8 = 62^{\circ}$ , $m\angle 7 = 118^{\circ}$ Vertical angles
$m \angle 2 = 31^{\circ}$ Sum of internal angles in a triangle
$m \angle 5 = 31^{\circ}$ Sum of internal angles in a triangle
$m \angle 1 = 59^{\circ}$ Sum of internal angles in a triangle/Result

The missing measures are listed below:

$m \angle 1 = m \angle 3 = m \angle 6 = 59^{\circ}$
$m\angle 2 = m\angle 4 = m\angle 5 = m \angle 11 = 31^{\circ}$
$m\angle 7 = m\angle 8 = m\angle 9 = m\angle 10 = 118^{\circ}$
