In this case, to flip any of the points to map
up accurately to the other points, we would have to do a transformation of reflection
about the y-axis. The reason behind this is that out of other transformation
process, we can only achieve the image of triangle ∆A’B’C’ through reflection.
Dilation will not work since it only changes
the size of the object. The shape and position will not affected.
A translation will not work because although
the shape can move, it still needs to flip to achieve triangle ∆A’B’C’.
A rotation will also not work because when you
rotate it, the shape will still not map over the new one.

reflect triangle ∆ABC about the y-axis.</span></span>
#1 would be 12 cm as the actual length of the thermos! This is because the scale given is 1:3 right? if you find what number 1 is multiplied by to get 3, you will obviously have 3. then, the given length of the thermos would be multiplied by 3, so it would be 3 x 4, which would be 12!

Answer:
I can tell you the first one and you can figure it out from there. 70 is 40% persent of what number? Well, we can chop 40% to 20% and chop 70 in half and we get 35. So 35 = 20% So we multiply 35 by five, and get 175. So 70 is 40% of 175.
Step-by-step explanation:
Write it as a power of 10
200 x 10
2 x 10^2
