Answer:
13.7
Step-by-step explanation:
a^2+b^2=c^2. 9.2^2 +x=16.5^2 x=16.5^2-9.2^2. x=root187.61 which is 13.7.
Hope this helps plz mark brainliest :D
Answer:5
Step-by-step explanation:
Form the equation 27.75n+5.50=144.25
Subtract 5.50 from 144.25.
144.25-5.50=138.75. Now you have 27.75n=138.75. Divide 138.75 by 27.75, 138.75/27.75=5. So n=5
Answer:
ok so first we divide 54 by 6 and get 9 so now we now that we have two sixes and two 9s for our edges now we add 6 plus 9 plus 6 plus 9 and we get 30
Answer:
cost = 1296 × 2 = $2592
Step-by-step explanation:
The concrete is likely a rectangular prism base on it dimension . The width, length and height is known. The volume of the prism should be calculated since the concrete prize is known base on it volume.
volume of a rectangular prism = Lwh
where
L = length
w = width
h = height
volume = Lwh
volume = 18 × 18 × 4
volume = 1296 ft³.
The cost of the concrete is $2 per cubic ft. Therefore, the volume for 1296 ft³ can be calculated below
$2 is the cost for 1 cubic fit
how much for 1296 cubic ft
cross multiply
cost = 1296 × 2 = $2592
