Answer:
20 students
Step-by-step explanation:
The percentage of students scoring a B or A = 38 + 25 = 63%
We need to evaluate 63% of the 32 students who did the test
(63/100)*32 = 20.16
Therefore, approximately 20 students earned a B or higher
Answer:5
Step-by-step explanation:
Volume of a cylinder = πr² h
V = volume
R = radius
H = height
² = squared
radius = 10 cm
Height = 8 cm
V = π10²×8
V ≈ 3.14 * 100*8
V ≈ 2512
Distribute the negative sign

Combine like terms
-9x^2 + 7x^2 = -2x^2
9x - 3x = 6x
13 - 6 = 7
