Answer:
Partial Answer
The height of one floor is 12ft.
Step-by-step explanation:
84/7 = 12
At 16 feet we have
16 = 3 + 30t - 16t^2
16t^2 - 30t + 13 = 0
t = [- -30 +/- sqrt(30^2 - 4*16*13) ] / 32
t = 1.20 , 0.68 seconds answer ( correct to the nearest hundredth)
To take a percent, move the decimal point of the percent two places to the left. 7% = 0.07
Then multiply:
12.60 • 0.07 = 0.88
12.60 + 0.88 = 13.48
The total cost is: $13.48
Answer:
26.88
Step-by-step explanation:
20%*22.40=4.48
22.40+4.48=26.88
Answer:
The coordinates of A could be anything in the form of (x, y, z) if you have a third axis. First you count where A is on the x-axis then the y-axis and if you have a 3-dimensional graph then the z-axis.
