Answer:
Last year there were 1070 students.
Step-by-step explanation:
Since 856 students represent a 20% drop from last year's number of students, then 856 students is 80% of last year's number.
80% of x = 856
0.8x = 856
x = 856/0.8
x = 1070

4*3+6+3=17
hope this helps!
Answer:
answer is 36 centimeter
Step-by-step explanation:
volume of a cylinder=πr^2h
1696=3.14*r^2*15
1696=47.1=r^2
1696-47.1=r^2
1648.9=r^2
=r
40.60 =r
here according to the question and option given 40.60 is closest to 36 centimeters.so answer is option d.
