D. 7 miles
Step-by-step explanation:
26.5/4 =6.62
So the best estimate is 7 miles
Answer:
Step-by-step explanation:
You know that the triangle ABC and the triangle DEF are similar.
Therefore, if the lenght of AC is 12 centimeters and the lenght of DF is 10 centimeters, then you can find the ratio as following:
Then, the calculte the length of EF, you must multiply the lenght BC of the triangle ABC by the ratio obtained above.
Therefore, the lenght EF is the following:
Answer:
sqrt of 3m (sorry I can't figure out how to get the symbol)
Step-by-step explanation:
M+2n^2=7m
2n^2=7m-m
2n^2=6m
n^2=3m
n= sqrt(3m)
Answer:
36-54i
Step-by-step explanation:
(9+9i)(-1-5i)
v
-9-9×5i-9i-9i×5i
v
-9-45i-9i-45i^2
v
-9-45i-9i-45×(-1)
v
(-9)-45i-9i+(45)
v
36(-45i)(-9i)
v
36-54i
<ACB = 1/2(100 - 42)
<ACB = 1/2(58)
<ACB = 29
answer is A. 29
