Answer:
-8
Step-by-step explanation:
you only have to add -1 to -7
The museum is at (2, -1 3/4). To find the reflection, the y-value of the point becomes the opposite sign , but the x-coordinate remains the same. In other words, the hotel is the same distance away from the x-axis as the museum, just in the opposite direction. This means that the hotel is at (2, 1 3/4)
Answer:
Step-by-step explanation:
When you multiply and irrational by a rational, you are doing nothing to change the nature of an irrational number. The two numbers have different kinds of properties and though a multiplication can be indicated, there is no way you can change the properties of an irrational number with a rational.
Their properties just do not mix.
It is like take a solvent and mixing it with something that is not a solvent. You cannot do anything to anything to the insolvent to make it solvent simply by adding more. Their properties remain in tact.
Take 3 * 4√7
The properties of the 3 and 4 remain the same when multiplied and they can be combined. 3*4 = 12
But nothing can be done with √7. The 3 cannot effect it, anymore than what the 4 did.
Answer: Angles are 
and 
Step-by-step explanation:
Here, the ratio of the angles formed by diagonals and the sides of the rhombus is 6:5.
Let the angles formed by diagonals and the sides of the rhombus are 6x and 5x.
Where x is any number.
Thus, By the property of rhombus,
Diagonals perpendicularly bisect each other.
Therefore, 
⇒ 
⇒ 
⇒ 
Therefore, the angles formed by diagonals and the sides of the rhombus are 
and 
⇒ The angles of rhombus are 
and
Answer:
200 miles
Step-by-step explanation:
80 = 40% of the trip
Divide 40% and 80 by 10
40% / 10 = 4
80 / 10 = 8
8 = 4% of the trip
100 / 4 = 25
8 x 25 = 200
The trip is 200 miles.
