Answer:
5.38
Step-by-step explanation:
- 145.4 - 140.02 = 5.38
Answer: 2.5 mL
Step-by-step explanation:
Given : A patient is given a solution containing 0.625 g of calcium carbonate.
i.e. Patient required calcium carbonate = 625 mg [∵ 1 g = 1000 mg]
Let x be the amount of solution ( in millimeters) given to the patients.
Ratio of amount of calcium carbonate (mg) to amount of solution (ml) =![\dfrac{625}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B625%7D%7Bx%7D)
If the calcium carbonate solution contains 1250 mg per 5 mL,
Then, Ratio of amount of calcium carbonate to amount of solution =![\dfrac{1250}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1250%7D%7B5%7D)
By using proportion we have :-
![\dfrac{625}{x}=\dfrac{1250}{5}\\\\\Rightarropw\ x=\dfrac{5\times625}{1250}=2.5](https://tex.z-dn.net/?f=%5Cdfrac%7B625%7D%7Bx%7D%3D%5Cdfrac%7B1250%7D%7B5%7D%5C%5C%5C%5C%5CRightarropw%5C%20x%3D%5Cdfrac%7B5%5Ctimes625%7D%7B1250%7D%3D2.5)
Hence, 2.5 mL solution were given to the patient.
Add the total distances of how much he drives in the chart and yeah! :d
It has 5 lines of symmetry
