Answer:
Step-by-step explanation:
Use vertical angles to help solve the problem. Angles that are across from each other are congruent. For exmaple,  <2 = 85 degrees because the angle across from it is 85 degrees. I assume angle 1 is 95 degrees, so angle 3 would also be 95 degrees.

Answer:
The density of cube is 6.17959 
Step-by-step explanation:
The density is given by ration of a mass of body and volume occupied by a body.

Where, 
 is density.
 is density. 
m is mass of a body
V is the volume of a body
Given that one side of the cube is 0.53cm
Hence, the volume of a body is V= =0.148877
=0.148877
Now, the Density of the cube will be 



Thus, The density of cube is 6.17959 
 
        
             
        
        
        
Answer:
 
 
Step-by-step explanation:
The correct question is
Susan works as a tutor for $10 and hour, and as a waitress for $11 an hour. This month, she worked a combined total of 90 hours at her two jobs. Let t be the number of hours Susan worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month
Let
t -----> the number of hours that Susan work as a tutor
y ----> the number of hours that Susan work as a waitress
z ---> the combined total dollar amount she earned this month
we know that 

 -----> equation A
-----> equation A
we know that
The combined total dollar amount she earned this month is equal to the number of hours that Susan work as a tutor multiplied by $10 plus the number of hours that Susan work as a waitress multiplied by $11
 ----> equation B
 ----> equation B
substitute equation A in equation B
 
 
 
 
 
 
therefore
The expression for the combined total dollar amount is $(990-t)
