The correct answer: 7.428 inches
Explanation:
Given the equation is D(r) = 0.145r^2
Where D is the depth and r is the radius
Putting D = 8 inches in the equation
8 = 55.2
r^2= 8/ 0.145
r^2 = 55.2
R^2= 7.428 inches
The radius of depth is 7.428 inche

Step-by-step answer:
1/8" long piece is not very much. However, mathematically,
we divide the total length by the length of each piece to get the number of pieces. So
4 2/5 / (1/8)
= (5*4+2)/5 * (8/1) [convert to fraction, and division to multiplication
= (22/5) * (8/1)
= 176/5
= 35 pieces with 1/5" left over.

The surface area of the parallelogram based prism is 1548 units squared.
<h3>Surface area of a parallelogram based prism.</h3>
The prism has 2 parallelogram base and 4 rectangular faces.
Therefore,
surface area of the prism = 2 (area of the base) + area of the 4 rectangular faces
Therefore,
surface area of the prism = 2(12 × 17) +2(19 × 13) + 2(19 × 17)
surface area of the prism = 2(204) + 2(247) + 2(323)
surface area of the prism = 408 + 494 + 646
surface area of the prism = 1548 units²

Answer:
-1.3125
Step-by-step explanation:
-16(d+1) = 20
-16d - 1 = 20
+1 +1
-16d = 21
d = -1.3125
or -1.3
