Answer:
Richard's cumulative GPA = 2.5
Step-by-step explanation:
Richard's cumulative GPA for 3 semesters was 2.0 for 42 credits.
Average = 2
Total credits = 42
Average = sum of terms/total no of terms
2 = sum of terms/42
sum of terms = 84 ....(1)
His fourth semester GPA was 4.0 for 14 course units
Average = 4
Total credits = 14
sum of terms = 56 .....(2)
Average for 4 semesters,

Hence, Richard's cumulative GPA for all 4 semesters is 2.5.
Answer:
y is 70° and x is 40 °
Step-by-step explanation:
the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.
Answer: 80
Step-by-step explanation:
Sin x = cos (90-x)
Like sin 30 = cos (90-30) =cos 60
So
90-x=90-80
Then
X=80
Verify your solution by finding the sum of the angles of sin and cos, it will be 90
Answer: 2.3
Step-by-step explanation:
Once you add all of the numbers of shoes together you get 14 pairs. To find the mean, you have to divide the total number by the number of values which is 6.
