Answer:
aₙ= 47 -3n
Step-by-step explanation:
44, 41, 38, 35, 32
This is AP with 1st term of 44 and common difference of -3
nth term of this AP:
- aₙ= a₁+(n-1)d= 44+(n-1)*(-3)= 44 - 3n+3= 47-3n
12 tables seat 4 people = 48 seats
28 tables seat 2 people= 56
therefore there are 104 seats
Answer:
X = 75
Step-by-step explanation:
here, DY || FS ,
SO, Angle DFS = Angle JDY
( Corresponding angle pair )
Angle JSF = Angle JYD
( Corresponding angle pair )
Hence, triangle JDY ~ JFS ( By AA CRITERIA )
Now, JY / YS = JD / DF
=》42 / 63 = 50 / X
=》X = 50/42 × 63
=》X = 75
i hope you got it
The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
