Answer:
250 litters
Step-by-step explanation:
To solve this question, we first need to know the conversion from cubic meter to liter.
1 cubic meter is equal to 1000 liters.
So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:
1 m3 -> 1000 L
1/4 m3 -> x L
x * 1 = (1/4) * 1000
x = 1000 / 4 = 250 L
So we need 250 liters of water.
It's a false statement.
On the left side, 28 - 0.3 = 27.7
On the right side, 0.7 - 12 = -11.3
The equation says that 27.7 is equal to -11.3 , but it's not.
Answer:
$98.4.
Step-by-step explanation:
Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:
10 x 1.2 + 24 x 1.1 + 60 = X
12 + 26.4 + 60 = X
98.4 = X
Thus, the level 2 course will cost $ 98.4 next year.
