Mathematics

Answer:

14400km/h

Step-by-step explanation:

Given that

The speed of the car increased from 40 km/hr to 60 km/hr

And, the time taken is 5 seconds

we need to find out the acceleration of the car

So,

Here

u =  initial velocity =40km/h

v = final velocity =60km/h

t = time = 5s =5 ÷ 3600h

a = acceleration

Now as we know that

a = (v - u) ÷ t

= (60 - 40) ÷ (5 ÷ 3600)

= (20 × 3600) ÷ 5

= 14400km/h

A vessel has 4 liters and 500 ml of curd. In how many glasses, each of 25 ml capacity, can it be filled?
dalvyx [7]

Step-by-step explanation:

easy to look up : mili stands for 1/1000

so,

500 ml are 500/1000 liters.

25 ml are 25/1000 liters (a tiny glass).

and 1 Iiter is of course, 1000/1000 liters (1000 ml).

4 liters 500 ml are then

4×1000/1000 + 500/1000 = 4500/1000 l = 4500 ml.

how many glasses of 25 ml can be filled with that ?

this is the same question as into how many parts of 25 can 4500 be split ? or, how often does 25 fit into 4500 ?

all this is done by division :

4500 / 25 = 180

so, 180 of such glasses can be filled.

If the size of bacteria is 2000 initially and doubles after every half hour

It means in the 1st 30 min its size is 2000

And in 60 min its

30min=2000

60min=?

60×2000=120000

120000÷30

=4000

And in 9hrs

1hr=60min

9hrs=?

60×9=540min

30min=2000

540min=?

2000×540

=1080000÷30

=360000
