Answer
1530 cubic centimetres( to 3 sf)
workings in the picture below:)
7.5% of $80 = $6
Here's why:
Using proportions.
⠀
⠀
⠀ x 7.5
⠀ ------- = --------
⠀ 80 100
⠀
7.5 times 80 = 600
100 times x = 100x
600 divided by 100 = 6
x = 6
Answer:
#7 can be simplified to -10 √15x -40 √5
#8 = -20 √6x +30x√2
#9 = 10x√6+3 √15xx
#10 = -20√6a -15 √2
