Answer:
Volume of composite is 483 
Step-by-step explanation:
We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):
Volume of the prism = 7 x 12 x 3 = 252
Volume of the semi-cylinder = 
Therefore the sum of both volumes gives:
(252 + 230.907) = 482.907
WHich can be rounded to the nearest whole number as: 483
Let's say the APR is 5%. That means you get 5% of your balance back every year. The $100 balance would get $5 back, the $500 balance would get $25 back, and the $1000 balance would get $50 back. Therefore, all of the balances would take the same amount of time to double, and it would take all of them 20 years.
$5*20 years=$100
$25*20 years=$500
$50*20 years=$1000
Answer:
B. 29.5
Step-by-step explanation:
Cos=A/H
=12/x
x=12/cos66
105% =$34.02
100% (cost without sales tax) = 34.02/1.05 =$32.40
