A*25+b*35=10250
a +b = 350 | * -25
25a + 35b= 10. 250
-25a -25 b= -8.750
------------------------------
10b = 1500
b=1500:10
b=150 tickets cost 35 $
a= 350-150
a= 200 tickets cost 25 $
Since each table had 7 women and 3 men at each table, that would mean each table has 10 people. Since there are 9 tables he was waiting on, and 10 people at each table, multiply 9 x 10, and you will find that he served 90 people in total.
Answer:
67 eghan says the difference between the least amount of time it takes a student to say the alphabet and the greatest amount
Step-by-step explanation:
we have the function
Remember that
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2
In the general form of the equation of the sine
The amplitude is the factor A
so
In this problem
The amplitude is 1/2
using a graphing tool
Note that the amplitude is the height from the center line to the peak (the center line is the x-axis, so the distance is 0.5.
F ( x ) = tan ( 2 x );
f ` ( x ) = (1 / cos² x )· ( 2 x )` = 2 / cos² x
f` ( π/6 ) = 2 / cos² (π/6) = 2 / (√3/2)² = 2 : 3/4 = 8/3
