The answer to the question is C
Answer:
y = –3x + 9
Step-by-step explanation:
expand the equation y = –3(x – 3)
-3 × x is -3
-3 × -3 is +9
Answer:
<u>h ≥ 8 cm</u>
Step-by-step explanation:
Solving :
V ≥ 32 cm³
a = 4 cm²
h ≥ 32/4
<u>h ≥ 8 cm</u>
Answer:
we know,
area of circle = πr²
area of semicircle of circle having diameter of 16.
according to formula = πr²
radius = 16/2 = 8 cm
22/7 × (8)² → 22/7 × 64 → 1408/7 = 201.14/2 = 100.57 cm (approx.)
area of semicircle of circle having diameter of 20 cm.
22/7 × 20² = 22/7 × 400 = 8800/7 = 1257.14/2 = 628.57
to get the area of shaded part 628.57 - 100.57 = 528 cm² (approx.)

Answer:
9 small boxes and 15 large boxes
Step-by-step explanation:
x = small box
y = large box
x + y = 24
9x + 24y = 441
-9x - 9y = -216
15y = 225
y = 15
x + 15 = 24
x = 9
