Let sum of 3 numbers be x.
Average of 3 numbers and 8 =
25 =
100 = x +8
x= 92.
The sum of 3 numbers is 92.
Average of 3 numbers and 8 =

Answer:
t = 24 yards
Step-by-step explanation:
Since the trapezoids are similar then the ratios of corresponding sides are equal, that is
=
Substitute in given values
=
( cross- multiply )
0.25t = 6 ( divide both sides by 0.25 )
t = 24
Given:
Circle C and circle R are similar.
The length of arc AB is
The radius of circle C (AC) = 4 unit
The radius of circle R (QR) =6 unit
To find the length of arc QP.
Formula
The relation between s, r and is
where,
s be the length of the arc
r be the radius
be the angle.
Now,
For circle C
Taking r = 4
According to the problem,
or, [ eliminating
from both side]
or,
or,
Again,
For circle R
Taking, r = 6 and we get,
The length of arc QP is
or,
Hence,
The length of QP is . Option C.
