Answer:
the answer is d
Step-by-step explanation:
its the only answer that makes sense in my opinion
We know that
a) find <span>the ratio of the perimeters
</span><span>
the ratio of the perimeters is equal to the scale factor
</span>scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3
b) find <span>the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]</span>²*area smaller figure
scale factor²=area larger figure/area smaller figure
the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9
the answer Part b) is
169/9
the complete answer is
13/3 and 169/9
Answer:
These two lines are parallel and system of these equations have no solution
Step-by-step explanation:
Parallel Lines: Lines having same slope and different x and y intercept are parallel lines. System of such equations does not have any solution as these lines does not intersect at any finite points.
Standard form of line is 
where 
is slope and 
is y-intercept.
First Line:
Second Line:
Hence these two lines are parallel and system of these equations have no solution
Answer: 1 13/30 hrs left
Step-by-step explanation:
his class lasts 2 5/6 hrs...and he has already been in there for 1 2/5 hr
so the time he has left can be found by subtracting the time he has been there from the total time of the class
2 5/6 - 1 2/5....
(2 - 1) = 1 : (5/6 - 2/5 = 25/30 - 12/30 = 13/30)
so he has 1 13/30 hrs left
