Answer:
750 more movies.
Step-by-step explanation:
![1003 - 253 = 750](https://tex.z-dn.net/?f=1003%20-%20253%20%3D%20750)
A)
I:2.25*pretzels+1.5*drinks=463.50
II:pretzels+drinks=257
b)
with II:
pretzels+drinks=257
pretzels=257-drinks
substitute pretzels=257-drinks into I:
2.25*pretzels+1.5*drinks=463.50
2.25*(257-drinks)+1.5*drinks=463.50
2.25*257-2.25*drinks+1.5*drinks=463.50
-0.75*drinks=463.5-2.25*257
0.75*drinks=114.75
drinks=114.75/0.75=153
in II:
pretzels=257-drinks
pretzels=257-153=104
Answer:
The correct answer is D
Multiply by 1000 and divide by 3600
Step-by-step explanation:
We know that in 1 km we have 1000 m and in 1 h we have 60 minutes and each minute have 60 seconds, then we multiply 60*60 to know how many seconds are in an hour and we have that 1 h have 3600 s. Using a conversion factor we have:
![\frac{km}{h}(\frac{1000 m}{1km})(\frac{1h}{3600s})](https://tex.z-dn.net/?f=%5Cfrac%7Bkm%7D%7Bh%7D%28%5Cfrac%7B1000%20m%7D%7B1km%7D%29%28%5Cfrac%7B1h%7D%7B3600s%7D%29)
With this we can see that to convert a quantity from kn/h to m/s we must multiply by 1000 and divide by 36000
