Okay, well we're gonna find the LCM (least common multiple)
3: 3, 6, 9, 12, 15, 18, 21
7: 7, 14, 21
So...21 days
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.

= 8.25 mL
Hence, her measuring cup has 8.25 mL of medicine.
Answer:
4.02 meters.
Step-by-step explanation:
In the diagram, the length of the ladder is |AC|.
If the foot of the ladder is x meters from the base of the ladder
Then the distance of the ladder up the wall, AB=2x meters.
Using Pythagoras Theorem

Therefore, the distance of the ladder up the wall,
AB=2 X 2.01 =4.02 meters.
