Answer:
Correct answer is:
The transformation was a 180° rotation about the origin.
Step-by-step explanation:
Given the triangle RST formed by points:
![R (1, 1),\\S (3, 1)\ and\\T (1, 6)](https://tex.z-dn.net/?f=R%20%281%2C%201%29%2C%5C%5CS%20%283%2C%201%29%5C%20and%5C%5CT%20%281%2C%206%29)
is transformed using (x, y) → (–x, –y) such that coordinates of triangle R'S'T' :
![R' (-1, -1),\\S' (-3, -1)\ and\\T' (-1, -6)](https://tex.z-dn.net/?f=R%27%20%28-1%2C%20-1%29%2C%5C%5CS%27%20%28-3%2C%20-1%29%5C%20and%5C%5CT%27%20%28-1%2C%20-6%29)
Please refer to the attached image for the given dimensions and coordinates.
It is clearly visible that:
The given triangle RST has coordinates in first quadrant.
and the resulting coordinates R'S'T' are in third quadrant.
The rotation of angle from 1st quadrant to 2nd quadrant is
and
The rotation of angle from 2nd quadrant to 3rd quadrant is
.
<em></em>
<em> total rotation is </em>
.
You multiply them together so it is 360 it will sometimes also look like this
8(45+7) and with that you would then just multiply the 8 to the 45 and the 7

Answer:
20 kilograms of dough
Step-by-step explanation:
Given that;
12 kilograms working 6 hours
Rate = 12/6 kilogram per hour = 2 kilogram per hour
So,
In 10 hours he would produce;
Amount of dough = Time × rate
Time = 10 hours
= 10 hours × 2 kilograms per hour
= 20 kilograms of dough
