Answer:
6. Multiply 2 by 6
7. 71 + 9(8) = 71 + 72 = 143
8. 52 + 3(4) = 12 + 52 = 64
9. 19.25 + 2.75(7) = 19.25 + 19.25 = 38.50
10. 2(0.6)^2 + 4(0.6)(5) = 0.72 + 12 = 12.72
Srry if they r wrong
Alright
so
28% of 2 m³=0.28 times 2=0.56 m³ of silt in the first mixture
13% of the 1 m³=0.13 times 1=0.13 m³ of silt in 2nd
total is 0.56 m³+0.13 m³=0.69 m³ of silt
and the total is 2m³+1m³=3m³
so
0.69/3=0.23=23%
answer is D
It would be 8:5.
Ratios are very simple. There're basically just writing one number per the other number, exept instead of writing per, you write : or /.
