I don't know about estimate but the answer is 7 7/8 hours
Answer:
Jessica spent 10 months in Spain and 8 months in Colombia.
Step-by-step explanation:
Let x be the number of months Jessica lived in Spain, then she lived 18 - x months in Colombia.
She learned an average of 160 words per month when she lived in Spain, so she learned 160x words in Spain.
She learned an average of 200 words per month when she lived in Colombia, so she learned 200(18-x) words in Colombia.
In total, she learned a total of 3,200 new words, thus
Jessica spent 10 months in Spain and 8 months in Colombia.

Answer:
1. false; they are only skew if they have no congruency or similarity to the other segment
2. true
3. true
4. false; one is vertical and one is horizontal
5. true
6. false; they are not in the same locations on the cube
Step-by-step explanation:
7. m1 is 45 becuase it is alternate interior angles with b
m2 is 135 because the pair needs to add up to 180
The answer is 44, to solve, add 39 to 5
