Answer:
Hey there!
A congruence transformation maintains the size of the shape.
Thus, a dilation with scale factor 2 is not a congruence transformation.
Let me know if this helps :)
The probability of choosing one of us is 2 / 80 .
If that happens, then the probability of choosing
the other one is 1 / 79 .
The probability of both things happening is
(2/80) x (1/79) = 1/3160 = 0.0003165... = 0.032... percent
Answer:
Total number of painters = 25 painters
Step-by-step explanation:
Interior painting = 10 painters
These painters made up 40% of the painting crew
how many painters in all worked on this job?
Let
Total number of painters = x
Interior painters = 40% of x
10 = 40% * x
10 = 0.4 * x
10 = 0.4x
x = 10/0.4
x = 25 painters
Total number of painters = x = 25 painters
