Maggie bought a total of 30 pounds of three different types of produce to feed her hungry hippopotamus.
1 answer:
Let b pounds be the weight of bananas, d pounds - weight of dragon fruit and g pounds - weight of guavas Maggie bought.
1) Maggie bought a total of 30 pounds of bananas, guavas and dragon, then
b+d+g=30.
2)
- Bananas cost $1 per pound, then b pounds of bananas cost $b;
- Guavas cost $2 per pound, then g pounds of guavas cost $2g;
- Dragon fruit costs $3 per poundd pounds cost $3d.
In total Maggie spent $46, thus,
b+2g+3d=46.
3) The weight of the bananas (b pounds) that Maggie bought was twice the weight of the guavas (g pounds) and dragon fruit (d pounds) combined. So
b=2(g+d).

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.
