Answer:
9 green peppers and 3 red peppers
Step-by-step explanation:
Lupe's chili recipe makes 12 servings and uses green peppers = 12
Therefore, for 1 serving he uses =
= 1 green pepper
He uses red peppers for 12 servings = 4
for 1 serving he uses =
red pepper
∴ for 9 servings Lupe needs green pepper = 1 × 9 = 9 green peppers
and for 9 servings Lupe needs red pepper =
× 9
= 
= 3 red peppers
Lupe needs 9 green peppers and 3 red peppers for 9 servings
Let the exterior angle be y.
We know that the exterior angle is the sum of opposite two interior angles.
Therefore, y = 3x + 90 --- (1)
Also, y and 5x - 6 are linear pair.
Therefore, y + (5x - 6) = 180
Substituting y = 3x + 90 from (1), we get,
(3x + 90) + (5x - 6) = 180
8x + 84 = 180
8x = 180 - 84 = 96
x = 12 degrees
Hence, exterior angle y = 3(12) + 90 = 126 degrees.
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
