Answer:
6 for $24.96
Step-by-step explanation:
$5.90 * 3 = $17.70
Therefore 4 books would be $17.70 because you get one for free
$24.96/6 = $4.16
Therefore if you got 4 books it would be $16.64
So, buying 6 books would be cheaper.
Step-by-step explanation:
a(n) = a +(n-1)d
a=13
d=9-13=5-9=-4
°.° a(n) = 13 +(n–1)-4
hope this helps
Answer:
94.7 revolutions
Step-by-step explanation:
In the question above, we are given the following values for the fan
Angular velocity = 6.2 radians per seconds
Time = 1.6 minutes.
Step 1
We would convert the time given to seconds
1 minute = 60 seconds
1.6 minutes = ?
We cross multiply
1.6 minutes × 60 seconds
= 96 seconds
Step 2
Number of revolutions made by the fan is calculated as :
Angular velocity(rad/s)
× time(seconds)
Number of revolutions = 6.2 radians per seconds × 96 seconds
=595.2 radians
Converting from radians to revolution
1 radian = 0.159155 revolutions
595.2 radians =
Cross multiply
= 595.2 radians × 0.159155 revolutions
= 94.729056 revolutions.
Approximately to the nearest tenth = 94.7 revolutions.
Therefore, the number of revolutions the fan blade makes in 1.6 minutes is 94.7 revolutions.
