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.
Answer:
it is 3,100
Step-by-step explanation:
bc you cant round up 0 so your answer is 3.100
The x values can be anything, the y value is dependant on the x and your x value would depend on the scale of your x axis
Let us calculate the teacher's initial speed. It can be calculated as thus:
She does 5 papers in 30 minutes. Thus means her speed is 6 minutes per paper (Because
minutes per paper).
Now, if the teacher has to complete the remaining 30 papers in the remaining 150 minutes (2 hours 30 minutes=120+30=150 minutes), she will have to go through one paper in
minutes. Thus, her speed now will have to be 5 minutes per paper.
Now, we know that 1.2 times 5=6. Therefore, it will not be wrong to say that '' she has to be 1.2 times faster instead of 20% faster" because both mean the same.
Answer: 0.75 seconds
