To convert a percent to a decimal, divide the percent by 100.
0.8/100 = 0.008 <<<<<< answer.
Answer:
(20 + n)¢
Step-by-step explanation:
With Company X, it costs 35¢ to connect and then 5¢ for each minute.
So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢
Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.
So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.
Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)
Answer:

Step-by-step explanation:
*Notes (clarified by the person who asked this question):
-The triangle on the right has a right angle (angle that appears to be a right angle is a right angle)
-The bottom side of the right triangle is marked with a question mark (?)
<u>Triangle 1 (triangle on left):</u>
Special triangles:
In all 45-45-90 triangles, the ratio of the sides is
, where
is the hypotenuse of the triangle. Since one of the legs is marked as
, the hypotenuse must be 
It's also possible to use a variety of trigonometry to solve this problem. Basic trig for right triangles is applicable and may be the simplest:

<u>Triangle 2 (triangle on right):</u>
We can use basic trig for right triangles to set up the following equations:
,

We can verify these answers using the Pythagorean theorem. The Pythagorean theorem states that in all right triangles, the following must be true:
, where
is the hypotenuse of the triangle and
and
are two legs of the triangle.

Answer:
Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase. Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.

hopefully this explains it coz i don’t have a clue either
