Answer:
227 is the 74th term of your question.
Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.

Cross multiplication!
=
7 × 24 = 8x

=
8 and 8 cancels out
21 = x
Answer:
30
120
706.5
Step-by-step explanation:
circumference= 94.2 inches, circumference is pi x diameter so-
diameter = 94.2/pi inches.
Using 3.14 as an approximation for pi we get:
Diameter=30 inches.
So would need a length of at least
4x30 = 120 inches of felt for four wheels.
The area of the circular wheel is pi x diameter 2/4 square inches.
Area is 706.5 square inches which is how much felt is needed to cover one wheel.
