Answer:
2000 cm^2/min
Step-by-step explanation:
According to the given question,
12 m^2/h = ? cm^2/min
We know,
1 h = 60 min and 1 m = 100 cm
So, by putting the values we get
- 12 m^2/h = 12 × (100)^2/60
Thus the answer of the given question is 2000 cm^2/min .
Step-by-step explanation:
Let the number of books of Physics be x . Then , No. of chemistry books =3.5x
Now , according to question :
x+3.5x=90
Or , 4.5x=90
Or , x=90/4.5
Or , x=20
Now ,
3.5x= 3.5×20
= 70
Therefore , there were 70 chemistry books and 20 physics books in that question bank.
Answer:
3000 m
Step-by-step explanation:
Using Pythagoras theorem
Similarly
Length of the Tunnel = |AB|+|BC|
=1999.9+999.7
=2999.6
=3000 m
You would use the function root(Xsub2-Xsub1)^2+(Ysub2-Ysub1)^2.
Now plug in your numbers.
This gives you root(7-1)^2+(5-(-3))^2.
Simplify to root(6)^2+(8)^2. Simplify again to root36+64.
Simplify one more time to root 100. now solve.
Your answer is 10.
The answer is 20 because if you divide 15:20 by 5, you get 3:4. hope this helps!
