What's this "<span>13/255/99/2110/117" all about?
Write the ratio described:
6 1/9 tons 55 2 110
--------------- = ----- * ------- = ----------- This is the desired ratio.
6 1/2 tons 9 13 117</span>
Answer: 1/4
Step-by-step explanation:
We can actually write an equation to find what should be added to get -1.

We get this equaiton because the problem asks what should be added to -5/4 to get -1. We put x in place to see what number fits. X is being added to the -5/4.



Step-by-step explanation:
Y=9
Replace y in the equation:x+9=3
X=9-3=6
So it's D(6,9)
Answer:
The number will be 
Step-by-step explanation:
Let us assume the number as
.
Given:
⇒
less than twice a number that will be
, which is equal to half the difference of three times the number and 13
We have to find the number.
Solution:
The difference of three times the number and 13 could be represented as : 
The value be equal to
of this
⇒ 
As we can see here,
- That we got a equation ⇒

Now, we can solve the above equation:

We have multiply both sides by
⇒ 
then, ⇒ 
⇒
Hence we can say that number which was assumed as
will be 
Adjacent side to angle 60º=2/3
opposite side to angle 60º=b
hypotenuse=a
cos 60º= adjacent side / hypotenuse
cos 60º=(2/3) / a
a=(2/3) / cos 60º=(2/3) / (1/2)=4/3
tan 60º= opposite side / adjacent side
tan 60º=b / (2/3)
b=(2/3)*tan 60º=(2/3)* √3=2√3 /3
Answer:
a=4/3
b=2√3 /3
