1/8
If you can make the bottom numbers (denominator) The same that you can use subtract the top numbers like normally
Basically, the unit rate is 1.99/18 or 0.110.
If we round 1.99 to 2.00, we instead get 0.111~
Answer:
it is clawed ed-unity
Step-by-step explanation:
tfgggg
First, we determine the volumes of the posts may it be cylindrical in shape or rectangular prism.
(A) cylindrical:
( π(26.7/100)² - π(24.2/100)²)*(7.5) = 0.3 m³
(B) rectangular prism:
(40/100)²(7.5) - (35/100)²(7.5) = 0.28125 m³
Then, we calculate for the amount of substance
(A) cylindrical: (0.3 m³)(2700 kg/m³) = 810 kg
(B) rectangular prism : (0.28125 m³)(2700 kg/m³) = 759.375 kg
Then, calculate for the costs
(A) (810 kg)($0.38/kg) = $307.8
(B) (759.375 kg)($0.38/kg) = $288.56
Thus, the answer for A is rectangular post
B. About $19.24 can be saved.
3. A
2. C
Idk if you should repost this with a better pic though
