A.) 1/3 is your scale factor
The sum of 1010 and 210 would be 1,220
because the word “and” means addition so you add the two numbers together! hope this is helpful.
What does it say? Could you take a better picture
Height:shadow
so 3.5:1.06 and is the same as 50.5:x
we treat it as a fraction and get
3.5/1.06 and x/50.5
they should be equal
we know that if we multiply two equal fractions, with one flipped, then we will get 1 exg 1/2=4/8 1/2 times 8/4=8/8=1
so 3.5/1.06=x/50.5 3.5/1.06 times 50.5/x=1
176.75/1.06x=1
multiply both sides by 1.06x
176.75=1.06x
divide both sides by 1.06
166.745=x
round up to hundreds place
