➷ 4 parts red pigment = 8(4) parts of base = 32 parts of base
7 parts red pigment = 8(7) parts of base = 56 parts of base
12 parts red pigment = 8(12) parts of base = 96 parts of base
20 parts red pigment = 8(20) parts of base = 160 parts of base

Answer:
4 kg of sugar would contain 
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
Solve for x. Cross multiply.
Divide both sides by 3
4 kg of sugar would contain crystals.
<span>It doesn't matter that she guessed correctly on the first two questions, guessing the third question correctly is independent of guessing any other question correctly. Therefore, the probability is one out of four, 1/4.</span>
Hi there. I think that this question is supposed to go in the Physics category but I'll help you.
the equation for kinetic energy is 1/2mv^2.
Plug the given values in.
18=1/2(m)(3)^2
18=1/2m(9)
36=9m
m=4
