Answer :
Miranda has 8.25 milliliters of medicine in her measuring cup when she measures out 15 drops, assuming 20 drops equal 11 milliliters.
To solve this problem, we first need to determine the conversion rate between drops of medicine and milliliters (mL). According to the information given by Miranda, 20 drops of medicine is equal to 11 mL. Now, we want to find out how many milliliters are in 15 drops of medicine.
First, we set up a proportion to find the conversion factor:
20 drops = 11 mL
1 drop = 11 mL / 20 drops
Now, we calculate the volume for 15 drops:
15 drops × (11 mL / 20 drops) = 165 mL / 20
165 mL / 20 = 8.25 mL
Therefore, there are 8.25 milliliters of medicine in the measuring cup when Miranda measures out 15 drops.
Answer: Her measuring cup has 8.25 mL of medicine.
Step-by-step explanation:
As per given,
In 11 mL of medicine, there are 20 drops.
That means quantity in 1 drop = [tex]\dfrac{11}{20}[/tex] mL
Now , the quantity in 15 drops = 15 x quantity in 1 drop
= [tex]15\times\dfrac{11}{20}[/tex]
[tex]=\dfrac{33}{4}[/tex]
= 8.25 mL
Hence, her measuring cup has 8.25 mL of medicine.
