First year:
.3 x 2593 = 777.9
$2593 - $777.90 = $1815.10
Second year:
.3 x 1815.10 = 544.53
$1815.10 - $544.53 = $1270.57
Third year:
.3 x 1270.57 = <span>381.171
$1270.57 - $381.171 = $</span>889.39900
$889.39900 rounded to the nearest hundredth is $889.40
$180 for 6 months
Why: Well the equation is " y = 25x + 30 " where x represents the months. First you do 25 x 6 because the equation says $25 PER MONTH. After that, add the initial fee of $30 giving you the total of $180.
Answer:
D—
The histogram will have a horizontal or an x axis of time/minute intervals of the calls (5 minutes in each), and the vertical axis or y axis will be the number of calls made.
Answer:
The class in the second and longest bar graph (the one labeled 3) has the most students.
Step-by-step explanation:
When looking for the largest amount of something in bar graphs, the largest bar graph is correct. In this case the second bar graph is the longest, and we can see it indicates the class contains 28 students.
From the unit circle:
sin 30 = 1/2, cos 30 = √3 / 2, tan 30 = √3 / 3 , tan 60 = √3;
sin 30 * sin 60 = ( cos 60 * tan 30 ) * ( cos 30 * tan 60 )
Left side of an equation:
sin 30 * sin 60 = 1/2 * √3 / 2 = √3 / 4
Right side:
( cos 60 * tan 30 ) * ( cos 30 * tan 60 ) =
= ( 1/2 * √3 / 3 ) * ( √3 / 2 * √3 ) =
= √3 / 6 * 3 / 2 = √3 / 4
√3 / 4 = √3 / 4 ( correct )
