Darina [25.2K]

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.

Let x be the number of ml you need.

Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg

(1 ml)/(1 mg) = (x ml)/(0.1 mg)

Cross multiply.

1 * x = 1 * 0.1

x = 0.1

Answer: 0.1 ml

16 feet 10 minutes. 40 feet write as proportion
WINSTONCH [101]
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense

Triangle ABC is a right triangle. If AC =7 and BC=8, find AB . Leave your answer in simplest radical form.
almond37 [142]

AC=\sqrt{15\\

Step-by-step explanation:

AC is the base, BC is the hypotenuse, so the side length is AB.

We are given that AC=7 units, and BC is equal to 8.

Thus we have 8^2-7^2=(AB)^2

64-49=(AC)^2

15=(AC)^2

AC=\sqrt{15\\
