Answer:
$10.50
Step-by-step explanation:
First, find the cost of a pound of nuts.
Divide the price by the number of pounds:
60/4
= 15
Calculate the price with the 30% discount by multiplying this by 0.7:
15(0.7)
= 10.5
So, after the discount, a pound of nuts will cost $10.50
The angles are
1 & 2

Answer:
72 cm³
Step-by-step explanation:
Volume of a triangular pyramid = a*(h/3), where a is the area of the base triangle and h is the height from the base to the highest point.
We need to first find a, the area of the bas triangle:
Area of triangle = (1/2)bh, where b is the length of the base and h is the perpendicular height.
a = (1/2)12*4
a = 6*4
a = 24 cm²
Knowing a, we can know find the volume:
Volume = a*(h/3)
= 24*(9/3)
= 24*3
= 72 cm³
