Answer:
The average per week flow rate of students to the gym is <u>2700</u>.
Step-by-step explanation:
Given:
Baruch college has 1000 students in the spring of 2018. 30 percent of the students use the gym twice per week, 70 percent of the students use the gym three times a week.
Now, to find the average per week flow rate of students to the gym.
Total number of students = 1000.
So, 30 percent of the students use the gym twice per week:

Now, 70 percent of the students use the gym three times a week:

Now, to get the average per week flow rate of students to the gym by adding 30 percent of the students use the gym twice per week and 70 percent of the students use the gym three times a week:


Therefore, the average per week flow rate of students to the gym is 2700.
Answer:
You have to work backwards here
so if you had 100 dollars left and u spent 50 on a radio
100+50=150
Then You spent a 1/6 of it on stationery
So you mustve had 5/6 money left or 150 dollars
so you multiply that to find that
5/6=150/x
5x=900
x=180
so add 30 dolalrs to 150 and you have 180.
the you spent a third
you repeat the same process
the you have ur ANSWER
Angle R is the reference angle as its the only given angle (other than the 90 degree angle).
Opposite angle R is segment PQ
PR is the hypotenuse
Use the sine rule to find that...
sin(angle) = opposite/hypotenuse
sin(R) = PQ/PR
sin(19) = PQ/11
11*sin(19) = PQ
PQ = 11*sin(19)
PQ = 3.58124969902872 <<-- use a calculator (degree mode)
PQ = 3.58
Answer: 3.58
