While mining, Benny found a large metal bar that weighed 40 ounces. Benny was also able to determine that the bar contained 35% copper. How many ounces of copper are in the metal bar? Round your answer to the nearest whole number if necessary.

Step-by-step explanation:

=40×35%

=0.35 ounce

there are 0.35 ounce of copper in the metal bar

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
