Answer:
Option 2
Step-by-step explanation:
To find the sine of F, we have to find the length of the hypotenuse which is 2√13 from the Pythagorean Theorem. Then, sinF = opposite side / hypotenuse = 4 / 2√13 = 4√13 / 26 = 2√13 / 13. Hope this helps!
Answer:
k=2/5
Step-by-step explanation:
It is the ratio of the amounts y and x:
k = y/x
Put another way: y = kx
Set both fraction to a common denominator
7/16 and 4/16
now add them together
7/16 + 4/16 = 11/16
now subtract that from a full cake
16/16 - 11/16 = 5/16
there are 5/16 of the cake left
To get the equivalent you have to half the denominator and the numerator so therefore it is 1/5 as you divide it by 2.
I hope this helps you
