Answer:
80
Step-by-step explanation:
10 x 1 = 10
10 x 2 = 20
10 x 3 = 30
When you times any single-digit number with 10 just add a zero at the end of the number :)

Hope this helped ya!
Maybe you should write the raport between colours,,,i dont now exactly
Answer:
0.62kg
Step-by-step explanation:
Let
x = 40/kg coffee
y = 11/kg coffee
two equations can be derived from the question
x + y = 12 equation 1
40x + 11y = 114 (9.5 x 12) equation 2
multiply equation 1 by 11
11x + 11y = 132 equation 3
subtract eqn 3 from eqn 2
29x = 18
divide both sides of the equation by 29
x = 0.62kg
Multiplying by 2, the next one would be 160
Yes, this is a function because the mapping is one to one. The domain is the the different inputs that can be put into the function, so the domain is {1,2,3,4,5}. The range is the different outputs the function can produce. So the range would be {40,80,120,160,200}.
