Answer:
35%
Step-by-step explanation:
1. Multiply 78.75 by 100
78.75* 100 = 7875
2. Divide this by 225
7875/225 = 35
3. Make this number a precent 35%
Answer:
Step-by-step explanation:
(1/4) (2-5x+6)
=(1/4)(8-5x)
= 8/4 - 5x/4
=1/2 - 5x/4
Answer:
25.047 or roughly 25.
Step-by-step explanation:
I solved it wrong the first time then i double check with wolframalpha and got the correct number.
We know that the area of the tile is 18
and it makes a triangle, we also know the base and height. In this case the base is 2
and the height is also given which is
.
Area of triangle =
,
substituting we will end up with 18
=( 2
*
) / 2
Here is the tricky part
, i totally forgot about that lol.
Simplifying: we will get 18
= 
Now, in order to find the x, we will need to take the log of both sides.

Solving for x we end up getting:
= x
where x = 25.047.
To be honest I deserve a nobel prize not a brainliest lol.
Good question bro, take it easy.
The triangle height is calculated by Pythagorean Theorem
height^2 = 15^2 - 9^^2
height^2 = 225 - 81
height^2 = 144
height = 12
We can calculate the value of Angle a
cosine (a) = adj / hyp = 9/15 = .6
arc cosine (a) = 53.13 degrees
angle b = 180 -90 -53.13
angle b = 36.87 degrees
tangent b = height / x
tangent 36.87 = 12 / x
x = 12 / .75
x = 16
Yes, it's just that "simple" LOL
