Answer:16cm^3
Step-by-step explanation:
height=3
Length of base edge=4cm
Area of base= length x length
Area of base=4x4=16
Volume =1/3 x base area x height
Volume=1/3 x 16 x 3
Volume =(1x16x3) ➗ 3
volume=48 ➗ 3
Volume=16
Volume =16cm^3
Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x = 
Then
∠ BOC = 2x = 2 ×
=
≈ 54.67° ( to 2 dec. places )
Amount spent = $40 - $10 = $30
Price for each bag of popcorn = Amount spent / Number of bags of popcorn bought
Price for each bag of popcorn = 30 / 12 = $2.5
Answer will be D. Absolute value can never be negative.
