With a problem like this, set up a proportion (like when making lemonade from a mix).
is our proportion.
We fill in the the two weights and the 24 grams of medicine in the proportion and solve for the fourth piece not there.
We shorten medicine to M and we solve for M by cross multiplying.
The woman should get 19.2 grams of medicine.
Answer:
900 L
Step-by-step explanation:
Let x be the number of litres when the tank is full.
Then 5/6 x - 30 = 4/5 x
Solve this by converting to /30:
25/30 x - 30 = 24/30 x
1/30 x = 30
x = 30*30 = 900
Answer:
c
Step-by-step explanation:
Answer:
216.90 units
Step-by-step explanation:
Using Pythagoras Theorem:
a² + b² = c²
9² + 10² = 81 + 100 =181 = c²
c = √181 = 13.45
x² + y² = z²
6² + 13.45² = 36 + 180.9025 = 216.9025
= 216.90 units
