Using the given information, the average of r and s is 35.5
<h3>Calculating Average</h3>
From the question, we are to determine the average of r and s
From the give information,
The average of p, q and 27 is 28.
That is,
(p + q + 27)/3 = 28
p + q + 27 = 3×28
p + q + 27 = 84
p + q = 84 - 27
p + q = 57
Also,
The average of p, q, r, s and 27 is 31
That is,
(p + q + r + s + 27)/5 = 31
p + q + r + s + 27 = 5 × 31
p + q + r + s + 27 = 155
Thus,
57 + r + s + 27 = 155
r + s = 155 - 57 - 27
r + s = 71
The average of r and s is (r + s)/2
(r + s)/2 = 71/2
(r + s)/2 = 35.5
Hence, the average of r and s is 35.5

Lets get started!
height = -16t² + 91t + 42
After 3 sec means, t = 3, so we substitute t with 3
H = -16(3)² + 91(3) + 42
= -144 + 273 + 42
= 171 feet
D = -1<x<5
R = -3<y<3
ps can I have a brainliest
Circumference = 2 x pi x radius
27 in = 2 x 3.14 x radius
Solve for the radius
