Answer:
the distancev from 7±9y±11=0 is 0.97
The correct answer is A. 109 degrees.
Explanation:
Because the angles are supplementary, their sum is 180 degrees.
We know that one of them is 71 degrees, so we substract that from 180, therefore the other angle is 109 degrees.
Divide 7 by both sides and it should be s=4
Answer:
452.45mmm^2
Step-by-step explanation:
Step one:
Given data
outer radius R= 20mm
inner radius r= 16mm
let us find the area of the outer circle
Area= πR^2
Area= 3.142*20^2
Area= 3.142*400
Area= 1256.8 mm^2
let us find the area of the inner circle
Area= πr^2
Area= 3.142*16^2
Area= 3.142*256
Area= 804.35 mm^2
Hence the area of the section is
Area of outer- Area of inner
=1256.8-804.35
=452.45mmm^2
Absolute value equations are x^2 + x + n(number) so
My best guess is x^2 + x - 25
I’m sorry if I’m wrong
