a pump can fill 2400 litres an hour and its replacement model can fill 2.5% more, how man litters an hour can the new model fill

2,460 liters per hour

Step-by-Step Explanation:

The problem above requires only two operations: multiplication and addition. First, you have to answer this question: How much is 2.5% of 2,400 liters?"

You may do this by multiplying 2,400 by 2.5%.

2,400 x 2.5% (0.025) = 60 liters (this is the amount that the new model can fill more than old model).

Then, you have to add 60 liters to 2,400 liters.

2,400 liters + 60 liters = 2,460 liters

This means that the new model can fill 2,460 liters per hour.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
