Answer:
=1.53 hr
Step-by-step explanation:
In your question 30mm should be the thickness. Also, the minimum possible time is required.
SOLUTION:
The part should be oriented on its side in stereo lithography, thus laser Area A is same for all layers.
A= 1/2 (b x h) =>0.5 (36 x 38)
A= 864 mm²
Time to complete one layer 'T' is same for all layers
T= [(A/spot size x velocity)+ last time]
T=[(864/ 0.15x2200) +25]
T=27.62 sec
Number of layers 'n' is given by:
n= t/ layer thickness =>30/0.15
n= 200 layers.
Next is to determine minimum possible time required,
= n x T =>200 x 27.62
=5524 s /60
=92.06 min/60
=1.53 hr
Since Tameka has 30% worth of a dollar. The total value of the coins in her purse = 0.30* $1 = $0.30 or 30 cents
Total worth of coins in Tameka's purse = 30 cents
The coins that are available are 1 cent coin, 5 cents coin (nickel), 10 cent coin (dime) or a 25 cent coin (quarter)
The only possible way for her to have 4 coins that add up to 30 cents is that she has two dimes and two nickels
2 dimes + 2 nickels = 2 *10 + 2* 5 = 20 + 10 = 30 cents
Answer: 2 dimes (10 cent coins) and 2 nickels ( 5 cent coins)
