Answer:
8/15
Step-by-step explanation:
Since this is a right triangle
tan C = opp side / adjacent side
tan C = 8/15
62.5 mg sample will remain after 240 days
Step-by-step explanation:
Given
Half-life = T = 60 days
The formula for calculating the quantity after n half lives is given by:
Here
N is the final amount
N_0 is the initial amount
n is the number of half lives passed
The number of half lives are calculated by dividing the time for which the remaining quantity has to be found by half life
The quantity has to be calculated for 240 days so,
Given
Putting the values in the formula
Hence,
62.5 mg sample will remain after 240 days

There is nothing to solve.
You can simplify the expression by making use of the distributive property and collecting like terms.
.. 7(2 -j) -5
.. = 7*2 -7*j -5
.. = 14 -7j -5
.. = 9 -7j
Answer:
x=116
Step-by-step explanation:
180-C will get you F since they are adjacent angles, which would be 116. We know that the opposite angles of a parallelogram are equal, so x=116
