Answer:
34
Step-by-step explanation:
4(2)-2(7)+40
8-14+40
-6+40=34
The first thing to do is find the rectangular warehouse area.
We have then:
A = (12) * (18) = 216
A = 216 m ^ 2
We now look for the area of each acoustic tile square:
A '= (1) ^ 2 = 1
A '= 1 m ^ 2
We look for acoustic tile squares number:
N = (A) / (A ')
N = (216) / (1)
N = 216
Finally we look for the total weight:
W = (1/4) * (216)
W = 54 Kg
Answer:
The total weight of the tile required to cover the ceiling is:
W = 54 Kg
Answer:
see explanation
Step-by-step explanation:
(1)
x² - 6 = 2 - 18x ( add 18x to both sides )
x² + 18x - 6 = 2 ( add 6 to both sides )
x² + 18x = 8
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(9)x + 81 = 8 + 81
(x + 9)² = 89
(2)
(x + 9)² = 89 ( take square root of both sides )
x + 9 = ±
( subtract 9 from both sides )
x = - 9 ±

Answer:
The price of one ticket is $76.
Step-by-step explanation:
5% of $330 is $16.50 and 45% of $330 is $148.50. Add those two together and then add $13 to it. You should get 178 and subtract it from 330 which leads you to 152. It asks for the price of one ticket, so you divide that by 2 which results to $76.
