We have given three school there, School A, School B and School C.
We are going to use following formula.
Total number of student in a school = Mean of number of student × Number of classrooms.
School A
Mean of students in School A = 32.5.
Number of classroom in School A = 25.
Number of students in School A = Mean × number of classrooms = 32.5×25 = 812.5
School B
Mean of students in School B = 29.6.
Number of classroom in School B = 12.
Number of students in School B = Mean × number of classrooms = 29.6×12 = 355.2
School C
Mean of students in School C = 15.3.
Number of classroom in School C = 10.
Number of students in School C = Mean × number of classrooms = 15.3×10 = 153.
Total sum of number of classes in all schools = 25+12+10 = 47.
Total sum of all students in all schools = 812.5 +355.2 +153 = 1320.7 .
The mean number of students per classroom for all the schools combined =
= 
= 28.1
The mean number of students per classroom for all the schools combined= 28.1
The GCF of 12, 21, and 30 is 3.
The factors of 12 are: 1, 2, 3, 4, 6, 12
<span>The factors of 21 are: 1, </span>3, 7, 21
<span>The factors of 30 are: 1, 2, </span>3, 5, 6, 10, 15, 30
<span>Then the greatest common factor is 3.
</span>
The GCF of 11, and 44 is 11.
The factors of 11 are: 1, 11
The factors of 44 are: 1, 2, 4, 11, 44
Then the greatest common factor is 11.
Hope this helps.
Answer:
He paid $253.09 in interest.
Step-by-step explanation:
To find how much did he pay in interest, we use the simple intrest formula, that is given by:
In which I is the value paid in interest, P is the money borrowed, r is the yearly interest rate and t is the time.
In our problem, we have that:
He borrowed $4,400, so 
At 4.75% yearly. We measure the time in days, so we have to divide this value by 365. So 
.
From December 26, 2019 to February 21, 2021, there are 422 days, so 
.
He paid $253.09 in interest.
Answer:
Step-by-step explanation: one has to be 90 degrees, so 34 plus 90. The angles of a triangle always add up to 180 so, subtract the answer of 34 plus 90 from 80 and you should get the answer.
