20% because 10% of 40 is 4 so 4+4=8 then that is 10%+10% so 20% will be your answer. :)
We let x be the length (in minutes) of a certain science class. 65% of this period is spent with the experiment which lasted for about 52 minutes. Mathematically, this can be expressed as,
52 = (0.65)(x)
The value of x from the generated equation is 80. Thus, the science class is 80 minutes long.
D (x, y) ---> (x, -y)
We can look at Point X and Point X'.
Point X is at (2, -2), and Point X' is at (2, 2).
The y-value has been multiplied by -1, or turned positive, so the answer would be D.
Answer:
The answer to your question is: 48.6 ft
Step-by-step explanation:
See the picture below
Use the Thales's theorem to solve this exercise
x / 27 = 45 / 25
x = 45(27) / 25
x = 1215 / 25
x = 48.6 ft
Answer: 
Step-by-step explanation:
You know that "Z" is the midpoint of "YA". This means the following:

Now, you know that the expression for "YZ" is:

And the given expression for "ZA" is:

Knowing these expressions, you can substitute them into
, as following:

Finally, you must add these expressions in order to get "YA".
Therefore, this is:
