Surface area for a cuboid of length, l, bredth, b and height h.
= 2*(lb + bh + lh)
for 15 by 7 by 4 1/2 = 15 by 7 by 4.5
Surface area = 2*(15*7 + 15*4.5 + 7*4.5)
= 2*(105 + 67.5 + 31.5)
=2 *(204) = 408
Surface area of box = 408 in²
Answer:
a)0.8280
b)0.7691
c)0.4503
Step by step Explanation:
It was Given that 13% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).Each shaft is independent of the other and probability for non conforming is the same for each trial.
If X the denote the number among these that are nonconforming and can be reworked. Then
n =200 and
p = 0.13
Then, CHECK THE ATTACHMENT FOR DETAILED EXPLATION
Oh yes... Wonderful Proportions. There are ways to do proportions but this is how I learned how to do them :
PART %
=
WHOLE 100 That is the formula. I'm not sure of an example but I hope it helps
Flat fee for the 4 days = 29*4 = $116
Cost day 1 = 0.12 * 140 = $16.80
Cost dat 2 = $1.80
Cost day 3 = $1.80
Cost day 4 = $16.80
Total fixed cost = $153.20 Answer
Answer:
D. a + 4b – 24
Step-by-step explanation:
4(1/4a + b – 6)
distribute
4*1/4a + 4* b -4*6
a +4b-24
