Answer:
200 questions
Step-by-step explanation:
Given data
Let the total questions be x
so that
21% of x= 42 questions
let us solve for x
21/100*x= 42
0.21*x= 42
0.21x= 42
Divide both sides by 0.21
x= 42/0.21
x= 200 questions
Hence the questions are 200 questions
We have that
<span>A' (2,1)
C(-2,2)-------> </span>Using the transformation-----> C' (-2+2,2+1)----> C' (0,3)
with
A' (2,1) and C' (0,3)
find the distance <span>C'A'
d=</span>√[(y2-y1)²+(x2-x1)²]----> d=√[(3-1)²+(0-2)²]----> d=√8----> 2√2 units
the answer is
the distance C'A' is 2√2 units
