2x+20=58 then your would subtract 20 from 58 which would turn into 38 and your would divide 38/2 it would be 19 so the answer is x=19 if I’m not mistaken this is correct hope this helps
Answer:

Step-by-step explanation:
From the question we are told that:
Radius 
Height 
Rate 
Surface Radius 
Generally the equation for Volume is mathematically given by

Since radius to height ratio gives



Therefore


Generally the equation for Change of Volume is mathematically given by





Answer:
173.01
Step-by-step explanation:
To area of a sector or portion of a circle is found using:

Substitute N = 50 and A = 27.93.
It becomes 
The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.
200.94 - 27.93 = 173.01
I believe that triangle B and E are right triangles.
Option b) and c) is correct, i.e. 2/3 and 0.66(line over 66)7
6/9 is a rational number.
similar ration number can be given as -
<h3>What is rational number?</h3>
Rational numbers are the numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.
From the option, by above definition 2/3, 0.66(line over 66)7 seems to be an equivalent rational numbers because
6/9=2/3= 0.66(line over 66)7.
Thus, Rational numbers 2/3, 0.66(line over 66)7 are equivalent to 6/9.
