Step-by-step explanation:
y is the hypotenuse.
to find the hypotenuse:
a² + b² = c²
c = √ ( a² + b² )
y is the hypotenuse, a = 3, b = 3
y = √( a² + b² )
y = √ ( 3² + 3² )

Step-by-step explanation:
For surface area all you have to do is multiply each number by one of the other numbers x2.
Step-by-step explanation:
The final grade is the average of the two semesters.
70 = ½ (60 + x)
x = 80
So Catherine needs a Semester 2 grade of 80%.
The average of RC3 and RC4 is ½ (62 + 53) = 57.5. This accounts for 90% of the Semester 2 grade. The other 10% is the Spring final.
80 = 0.90 (57.5) + 0.10 (x)
x = 282.5
Catherine would have to score 282.5% on the Spring final in order to pass.
