Answer:
A is the answer
Step-by-step explanation:
Answer: 25%
Step-by-step explanation:
Given : A pharmacist added 50 g of drug to make a total of 200 mL of solution.
Here, Resultant solution = 200 mL
Amount of drug = 50 g
We know that 1 gram = 1 ml
So, we can say the amount of drug = 50 ml
Now, the percentage of drug in the resultant solution:-

Hence, the percentage of drug in the resultant solution= 25%
Answer:
Area = 28 cm² (check the attached diagram for better clarity)
Step-by-step explanation:
The question is incomplete but let's see a similar example
The front of a rectangular pyramid can refer to either one of two possibilities: it could be either the side that has the breadth and the height or the side that has the length and the height. In this case, we were given the formula for calculating the area of the front face of this rectangular prism as the product of breadth and height
Mathematically,
A = bh
From the attached diagram, we will see the properties of the rectangular prism as:
length = 5 cm, breadth = 4 cm, height = 7 cm
To calculate for the front face, we use A = bh,
⇒ A = 4 * 7 = 28 cm²
Example 2
If the breadth of the rectangular prism is 2 cm and the height is 3 cm, we have:
A = 2 * 3 = 6 cm²
Answer:
The answer is A, 18.84.
Step-by-step explanation:
The two points are 6 places apart, so that can be 6 units as radius. To find the circumference of a circle you do r x 3.14 (to abbreviate pi). 6 x 3.14 is 18.84 so A is your answer.
