Answer:
Step-by-step explanation:
1 cm = 10 mm
a) 0.1 cm = 1 mm
1 mm = 1000 m
b) 25000mm = 25 m
1 g = 0.001 kg
c) 7g = 0.007 kg
1ml = 0.000001
d) 30000ml = 0.03 kl
Answer:
The given situation is in direct variation.
The dependent variable is the distance covered and the independent variable is the number of hours.
Step-by-step explanation:
We are given the following information in the question:
Steve drove 300 miles in 5 hours.
After stopping for gas, he drove an additional 120 miles in 2 hours.
We calculate the ratios and if these ratios are equal then, we can say that the situation represent a direct variation.
For direct variation, the equation is of the form y = kx that is , we can write,

To check the ratio:

Thus, the given situation is in direct variation.
The dependent variable is the distance covered and the independent variable is the number of hours.
Answer:
12 Days.
Step-by-step explanation:
12×25=300
400+300=700
1000-300=700
Answer:
NaOH(s) --> Na+(aq) + OH–(aq)
Step-by-step explanation:
A basis of Arrhenius is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution.
So the answer is :
NaOH(s) --> Na+(aq) + OH–(aq)
