Answer: i really dont know
Step-by-step explanation: but 46
Answer:
93 degrees
Step-by-step explanation:
first, lets add 38+49 to see the sum
38+49=87
since the sum of all three angles in every triangle equals 180, we can subtract this sum from 180 to get the answer
180-87=93
so the missing angle would be 93
Answer:
-6x^2-288
Step-by-step explanation:
18x - 432 - 18x - 6x² +144
Combine like terms
-6x^2+18x-18x-432+144
-6x^2-288
Answer:
<em>(D).</em>
Step-by-step explanation:
= A + 
(A). 12 + 16 > 20
(B). 10 + 18 < 30
(C). 4 + 5 < 12
<em>(D). 8 + 16 = 24</em>
Answer:
130.826 kilojoules
Step-by-step explanation:
The Work required to pump water = pgV
Where, p = density of water = 1000 kg/m³
g = acceleration due to gravity = 9.81ms-¹
V = volume of water
Since, radius r = 5 ft and height h = 9ft
Volume of water in the cylindrical tank = (2/3)πr²h
V = (2/3)π *5²*9 = 471.24 ft³ = 471.24 * 0.0283m³ = 13.336m³
Work required = 1000*9.81*13.336
W = 130.826 KJ
Therefore, the work required to pump water 2/3 of the volume of the cylindrical tank = 130.826 kilojoules.
