Answer:
64 : 343
Step-by-step explanation:
When working with scale factors
Lengths are related by the scale factor
perimeters are related by the scale factor
areas are related by the scale factor squared
volumes are related by the scale factor cubed
The scale factor is 4:7
The volumes are related by 4^3 : 7^3
64 : 343
Answer : 
Explanation:
Since we have given that
n(U) = 120, where U denotes universal set ,
n(F) = 45, where F denotes who speak French,
n(S) = 42 , where S denotes who speak Spanish,
n(F∪S)' = 50
n(F∪S) = n(U)-n(F∪S) = 120-50 = 70
Now, we know the formula, i.e.
n(F∪s) = n(F)+n(S)-n(F∩S)
⇒ 70 = 45+42-n(F∩S)
⇒ 70 = 87- n(F∩S)
⇒ 70-87 = -n(F∩S)
⇒ -17 = -n( F∩S)
⇒ 17 = n(F∩S)

Answer:
-1.96312>-2.2360
Step-by-step explanation:
first find -
which is -2.2360679775
now round it to match the lenth of the other problem
-1.96312...
-2.2360...
now remember that the bigger the negitive number, the smaller it really is,
so
-1.96312>-2.2360
Answer: 9 fewer
Step-by-step explanation:
Add 13 and 11 which gives you 24. Then add 8 and 7 which gives you 15. Then subtract 24 - 15 which gives you a difference of 9.
Answer:
2x + 4y = 14 = x= −2y+7
3x - 4y = -39= x= 4=3
