Answer:
y ≠ 9, y ≠ 3
Step-by-step explanation:
y² -12y +27 = (y - 9) (y - 3)
Denominator ≠ 0
y ≠ 9 or y ≠ 3
Answer:
18h
Step-by-step explanation:
let the number of ripe apples on a tree be x
2x/3 = 1/2
x = 1/2 ÷ 2/3 = 3/4
time taken for him to pick all the ripe apples from 1 tree = 3/4 h
total amount of time taken = 24 x 3/4 = 18h
Answer:
m∠A ≈ 39.865°
Step-by-step explanation:
C² = 16² + 15² - 2 × 16 × 15 × cos (97°)
=> C = 23.22708085
sin (97°)/23.22708085 = sin A/15
=> sin A = sin (97°) × 15/23.22708085
=> A = 
(sin (97°) × 15/23.22708085)
=> A ≈ 39.865
Answer:
11.3
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2
8^2+8^2=128
the square root of 128 is 11.3137085
then you round to the nearest tenth and get 11.3
