Answer:
2.236
Step-by-step explanation:
you could estimate it to be between 2 and 3 (because 5 is between 4 and 9)
or you just put it into a calculator
Answer:
B
Step-by-step explanation:
To find how many hours she worked you must divide $65 by $5 and B is the only equation where you can do that.
The answer for this is 12.
Answer:
Step-by-step explanation:
Since DE is parallel to AB, it means that Triangle CDE is similar to triangle CAB. This means that the ratio of the length of each side of ∆CDE to the length of the corresponding side of ∆CAB is constant. Therefore,
AB/DE = DC/CA
Therefore,
DE/40 = 15/24
Cross multiplying, it becomes
24DE = 40 × 15
24DE = 600
Dividing the left hand side and the right hand side of the equation by 24, it becomes
24DE/24 = 600/24
DE = 25
The relationship between triangle CDE and triangle CAB is similar triangles. This is because CD is parallel to AB as given.
