If I have 4 A’s and 1 B, what is my GPA?
svetoff [14.1K]

Answer:

3.8

Step-by-step explanation:

Hey! Let's start by assuming that these are all normal courses, and that <u>GPA is given by the following scale:</u>

A - 4.0

B - 3.0

C - 2.0

D - 1.0

F - 0.0

That said, this question really just involves calculating the averages.

To find the average, we add all the values together and divide the sum by the total number of values.

<u>Therefore, our expression would look like:</u>

(4.0 + 4.0 + 4.0 + 4.0 + 3.0)/5

This is because there are 5 total values.

Simplify:

19/5

3.8

This means your GPA would be 3.8

3. Classify the triangle with the given side lengths as acute, right, obtuse, 10 points
Alex_Xolod [135]

Answer:

3) Obtuse

4) Right

Step-by-step explanation:

3)

11 + 13 > 25 It is a triangle

11² + 13² = 25²

121 + 169 = 625

290 ≠ 625

Since hypotenuse is larger, the triangle is obtuse

4)

21 + 28 > 35 It is a triangle

21² + 28² = 35²

441 + 784 = 1225

1225 = 1225

Since the hypotenuse is equal to the legs, it's a Right triangle
