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) =
If the calcium carbonate solution contains 1250 mg per 5 mL,
Then, Ratio of amount of calcium carbonate to amount of solution =
By using proportion we have :-
Hence, 2.5 mL solution were given to the patient.
Answer:
C) QT
Step-by-step explanation:
We must first find the coordinates of C(x,y) which divides AB in the ration m:n=3:2.
We use the formula
and
We plug in the coordinates of A(-5,9) and B(7,-7) and m=3, n=2 to get:
and
C has coordinates
The line segment that contains C is
