Answer:
He lost 147.35 marks
Step-by-step explanation:
Take the total marks and subtract the marks he got to find the marks he lost
600-452.65= 147.35
-9+8k=7+4k
subtract 4k from both sides
-9+4k=7
add 9 to both sides
4k=16
divide both sides by 4
k=4
Answer:
Mauricio needs 10.5 liters of oil for frying.
Step-by-step explanation:
It is given that,
Mauricio can fry 6 potatoes using 1 liter of oil.
So, he can fry 18 potatoes using
= 3 liters of oil.
Thus, Mauricio fries 18 potatoes using 3 liters of oil per hour
Now, Mauricio wants to fry the 18 potatoes for 3.5 hours.
So, the total amount of oil needed by him = 3.5 × 3 = 10.5 liters.
Hence, Mauricio needs 10.5 liters of oil for frying.
It would be half an inch long because there is 6 halves in 3 so 5/6 of it would be half an inch
