Answer:
c. 21/32 inches
C. 1.992
b. 0.3125
Step-by-step explanation:
Given
The inside diameter = 1/2 inches
Wall thickness = 1/16 inches
clearance = 1/32 inches
As it is given that the outside diameter is twice the thickness and diameter.
So,
Outside diameter = 1/2 + 2(1/32)
= 1/2+2/16
= 1/2+1/8
=(4+1)/8
=5/8
We also have to give clearance of 1/32 inches so,
Diameter of hole = 5/8+1/32
=(20+1)/32
=21/32 inches
So the correct answer for question 1 is:
c. 21/32 inches
<u>Rounding off 1.99235 to three decimal places:</u>
1.992
C. 1.992
<u>Expressing 5/16 as a decimal fraction:</u>
0.3125
b. 0.3125
16 completely divides 5 so the answer is already 4 decimal places ..
