Answer:
Step-by-step explanation:
tan47=x/18
x=18tan47
cosCDB=7/x
cosCDB=7/(18tan47)
CDB=arccos(7/(18tan47))
CDB=68.74
Answer:
179 minutes
Step-by-step explanation:
- Divide both sides by 75.5 to see how many minutes it would take to drive 1 mile. (54 / 75.5) =108/151
- She can drive 1 mile in 108/151 minutes
- Times by 250. (108/151 * 250) 178.8
- 179 to nearest minute
You are using the distributive property so you will multiply all the numbers in the parentheses by 5. So the end expression would be 30m+20n-15p
This is something I’ve never seen before I think you have to add the numbers.
