Answer:
83 degrees
Step-by-step explanation:
vertical degrees show that angles across from one another have the same value. All three angles will add up to 180 degrees. Subtract both 56 and 41 from 180 degrees to get a remainder of 83.
Answer:
Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.
Step-by-step explanation:
An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075
Considering the GMAT score x, and the GPA y, this situation is modeled by the following inequality:

Robbin's GMAT score was 800.
This means that
, and thus:



What must her grade point average be in order to be unconditionally accepted into the program?
Solving the above inequality for y:



Thus:
Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.
Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x
