Answer:
B
Step-by-step explanation:
It is B because to find the volume you multiply all three values together, which gets you 68.448. I multiplied 9.2x3.1, which got me 28.52, and then I multiplied 28.52 by 2.4 which got me 68.448.
Answer:
-76
Step-by-step explanation:
A positive digit multiplied by a negative digit will result as a negative digit.
So,
6 · -8 = -48
Now if there is a problem where a number is added by a negative digit number, you turn the "plus" sign into a "negative" sign.
So,
- 48 + (- 28)
-48 - 28
If you subtract a negative by a negative, the answer will be negative BUT you have to ADD those two negative digits together and put the negative sign after.
- 48 - 28 = -76
I believe the answer is B.
Sorry is it's not but i strongly believe it is!!!
Given:
A train travels 288 km at a uniform speed.
If the speed has been 4 km per hour more it would have taken one hour less for the same journey.
To find:
The initial speed of the train.
Solution:
Let x km/h be the initial speed on the train.
New speed of train = (x+4) km/h
We know that,

Time taken by the train initially to cover 288 km is
hours.
New time taken by the train to cover 288 km is
hours.
It is given that If the speed has been 4 km per hour more it would have taken one hour less for the same journey.





Splitting the middle term, we get




We know that the speed cannot be negative. So, the only possible value of x is 32.
Therefore, the speed of the train is 32 km/h.
3/8
Just divide to find the equal decimal.
3/8 = 0.375
